Women's strategies for handling household detergents

Risk factor for children in the pandemic: the use of cleaning products at home

Background

Intensified cleaning protocols to maintain a safe environment during the pandemic caused an increase in the use of disinfectants. The use of cleaning products in safer conditions by mothers is one of the important practices that will reduce the risk of household accidents.

Objective

The aim of research was determine the practices of mothers about the safe use of cleaning and disinfectant products in the COVID-19.

Methods

Data were collected by online survey among 255 mothers of the children 0-6 age from April and July 2021. Percentage, mean and chi-square tests were used to evaluate the data.

Results

It was reported that the amount of cleaning product usage (69%) increased significantly, 26.3% of the mothers store the products in a locked cabinet and 29.4% use the product in the recommended amount. It was detected 28.7% of the mothers use disinfectants close to children. It was detected that 37.6% of the families were exposed to cleaning and disinfectant products. There was not significant difference between exposure situations and maternal age, education, employment status.

Conclusions

It can be suggested that health workers should organize screening and training programs for the community about safe cleaning and disinfection practices.

Consumer knowledge and awareness of the toxicity and handling of household products at a tertiary care center in Beirut, Lebanon

Household products intoxication is a common and preventable problem. Household product hazard awareness is lacking among consumers in Lebanon, posing a public health hazard. A cross-sectional observational study was conducted at the American University of Beirut Medical Center by administering surveys to 176 adult participants. The surveys focused on demographics, awareness of product toxicity, practices used to avoid intoxication, and sources of information. Each participant was given a score for behavior and awareness. Informative brochures were handed to increase awareness among consumers. We surveyed 176 patients, of whom (84.7%) were females with a mean age of 42.2 ± 13.5 years. Most were married (77.3%), had a college education (76.7%), were employed (62.5%), and were in charge of household cleaning (76.7%). Toilet cleaners were the substances most perceived to be toxic (94.0%). Most people (86.4%) had low to medium scores on behavior, while most (77.3%) had high scores on awareness. Male gender and using product labels as sources of information were associated with higher behavior scores, while referring to a friend or a relative as a source of information on product intoxication was associated with a lower behavior score. Greater awareness scores were strongly associated with being married, having a higher monthly income, and referring to warning signs presented on the labels as a source of knowledge. Unsafe handling and storage of household products are common among consumers in our population. Therefore, it may be necessary to launch education campaigns to improve consumer handling of household products.

Consumers' decision-making process when choosing potentially risky, frequently used chemical household products: The case of laundry detergents

Chemical household products are a common cause of accidents in the domestic sphere. Despite such products being associated with certain risks in the event of swallowing or contact with the skin or eyes, they are used in nearly every household worldwide for hygiene purposes. In most European countries, chemical household products feature warnings of the Globally Harmonized System (GHS) as well as other warnings. In this eye-tracking study (N = 147), which was conducted in a virtual environment, we examined (i) whether consumers use such warnings when choosing a laundry detergent, (ii) whether they consider information irrelevant to risk assessment and (iii) whether they make use of this information for their final product choice. For this, the participants were split randomly into three experimental groups (a risk priming group, an effectiveness priming group, and a control group) that each received different tasks while purchasing a laundry detergent. The results indicate that the warnings found on laundry detergents are effective when they are used, although the majority of consumers do not look at the warnings. Therefore, we suggest that the alternative placement of warnings or the use of simplified warnings should be considered to improve consumers' awareness of potential risks.

History of injury in a developing country: a scoping review of injury literature in Lebanon

BACKGROUND

Lebanon, an Eastern Mediterranean country, suffers a large burden of injury as a consequence of conflict and war, political instability, and the lack of policies and safety regulations. This article aims to systematically map and comprehensively describe the injury research literature in Lebanon and, to identify gaps for future research.

METHODS

MEDLINE, Embase, Eric and SafetyLit, and the grey literature, including conference proceedings, theses and dissertations, government and media reports, were searched without any date or language limits. Data were extracted from 467 documents using REDCap.

RESULTS

War-related injuries were the most prevalent type of injury in Lebanon, followed by homicide and other forms of violence. While existing literature targeted vulnerable and at-risk populations, the vast majority focused solely on reporting the prevalence of injuries and associated risk factors. There are considerable gaps in the literature dealing with the integration of preventive programs and interventions across all populations.

CONCLUSIONS

Lebanon, historically and currently, experiences a high number of injuries from many different external causes. To date, efforts have focused on reporting the prevalence of injuries and making recommendations, rather than implementing and evaluating interventions and programs to inform policies. Future injury related work should prioritize interventions and prevention programs.

Safe Use and Storage of Cleaners, Disinfectants, and Hand Sanitizers: Knowledge, Attitudes, and Practices among U.S. Adults during the COVID-19 Pandemic, May 2020

Cleaning and disinfection of frequently touched surfaces and frequent hand hygiene are recommended measures to prevent transmission of SARS-CoV-2, the virus that causes COVID-19. Since the onset of the COVID-19 pandemic, poison center calls regarding exposures to cleaners, disinfectants, and hand sanitizers have increased as compared with prior years, indicating a need to evaluate household safety precautions. An opt-in Internet panel survey of 502 U.S. adults was conducted in May 2020. Survey items evaluated knowledge regarding use and storage of cleaners, disinfectants, and hand sanitizers; attitudes about household cleaning and disinfection; and safety precautions practiced during the prior month. We assigned a knowledge score to each respondent to quantify knowledge of safety precautions and calculated median scores by demographic characteristics and attitudes. We identified gaps in knowledge regarding safe use and storage of cleaners, disinfectants, and hand sanitizers; the overall median knowledge score was 5.17 (95% CI: 4.85-5.50; maximum 9.00). Knowledge scores were lower among younger than older age-groups and among black non-Hispanic and Hispanic respondents compared with white non-Hispanic respondents. A greater proportion of respondents expressed knowledge of safety precautions than the proportion who engaged in these precautions. Tailored communication strategies should be used to reach populations with lower knowledge of cleaning and disinfection safety. In addition, as knowledge alone did not shape individual engagement in safety precautions, health promotion campaigns may specifically emphasize the health risks of unsafe use and storage of cleaners, disinfectants, and hand sanitizers to address risk perception.

Pattern of disinfectants use and their adverse effects on the consumers after COVID-19 outbreak

BACKGROUND AND OBJECTIVE

The aim of this study was to investigate the pattern of disinfectants use within outbreak of COVID-19 and estimate their adverse effects on the consumer's health.

METHODS

In this descriptive-analytical study, 1090 participants were entered into the study without age and gender limitations. A researcher-made electronic checklist containing 43 questions was applied to collect data. The checklist included three sections: demographic characteristics (8 questions), disinfection of body and non-living surfaces (21 questions), and adverse effects of disinfectants on health (15 questions).

RESULTS

87% of participants used the incorrect proportions of water and alcohol to make this disinfectant available at home. The percentage of people with wrong proportion of sodium hypochlorite was 74.2%. Approximately 42% of participants experienced at least one disorder on their hands, feet, eyes, respiratory or gastrointestinal systems after sequential uses of disinfectants. The most common disorders among the participants were found to be skin dryness (76.3%), obsession (42.2%), skin itching (41.2%), coughing (41.1%), and eyes irritation (39.5%). The mean frequency of hand washing and hand disinfecting were 15.28 and 10.74 times per a day, respectively, and the clean-up in case of surfaces was 2.99 times a day. The frequency of hand washing and disinfecting in women group (16.4 and 11.2 times a day) were higher than in men (14.0 and 10.3 times a day) group. In addition, these self-care actions in married people (15.6 and 11.0 times a day) were higher compared to those in single people (14.0 and 10.6 times a day).

CONCLUSION

Being unaware of participants with instruction for preparation and use disinfectants may harm their health. Therefore, it is suggested that the authorities provide the necessary training program for public through official media.

Consumers' perceptions of chemical household products and the associated risks

Accidents with chemical household products are prevalent worldwide and often involve young children. Previous research has shown that consumers use both analytical factors (e.g., warning symbols) and potentially misleading heuristics to evaluate the riskiness. However, it remains unclear whether consumers intuitively think of the specific risks of these products when handling them. We conducted an online survey with Swiss consumers (N = 1109) aiming to investigate consumer's spontaneous and prompted risk perception of chemical household products. First, we asked them about their free associations to laundry detergent, descaler, mold remover and essential oils. While participants were aware of the risks when prompted about them, they did not name them intuitively, but mainly thought of the possible uses and attributes of the product. Next, we examined prerequisites to safe handling of chemical household products. This included applied knowledge about the products, but also factors like perceived barriers to safe use. Finally, we assessed the predictors of perceived severity of accidents in order to estimate the potential behavioral changes that these predictors might elicit. For interventions, particular attention should be accorded to personal risk awareness and the perception of potential barriers, which were significantly related to the perceived severity of accidents.

Toxicological exposures reported to a telephonic consultation service at a tertiary care hospital in Lebanon

Introduction: This study aims to describe the epidemiology of toxicological exposures reported to a telephonic medical toxicology service at a tertiary care center in Lebanon during a 46-months period.Methods: This study is a secondary analysis of a database for a telephonic medical toxicology service at a tertiary care center in Lebanon. Clinical information from all pediatric and adult patients, presenting with intentional or unintentional toxicological exposure, was entered into the database by the medical toxicology team.Results: Four hundred and seventy-seven exposures were recorded from 1 March 2015 to 31 December 2018. Female patients were involved in 60.2% of cases. Children less than 5 years old constituted 23.5% of cases and adults aged 20-49 constituted 48.6%. Up to 51.6% of cases were intentional, with 37.7% resulting from suicidal attempts. The majority of patients displayed no effects (33.1%) or minor effects (39.2%). Almost half of patients were treated and discharged from the Emergency Department (ED) without further hospitalization, and another 18.9% of patients left the ED against medical advice. The most common pharmaceutical agents involved were sedative/hypnotics/antipsychotics (14.7%), analgesics (12.6%) and antidepressants (11.3%). The most common non-pharmaceutical agents involved were household cleaning substances (8.0%), pesticides (5.2%) and bites and envenomations (3.8%).Conclusions: The results of this study suggest that sedative/hypnotics/antipsychotics, analgesics, antidepressants and household cleaning substances are the most common agents involved. Adult women and children ≤5 years old constitute a large portion of patients with toxicological exposures. Prevention strategies and policies should be implemented to mitigate these hazards.

Barriers to the safe use of chemical household products: A comparison across European countries

Chemical household products, such as cleaning and washing products or pest control and garden chemicals, are frequently involved in poisonings in private households. Consumer research has identified a number of barriers that impede the safe use of these products, ranging from unfamiliarity, to misconceptions and a lack of risk perception, to behavioural or situational barriers. This study aimed at investigating these barriers for consumers in eight European countries. Participants from eight European countries were recruited and asked to fill out an online questionnaire on their familiarity with hazard pictograms, perceptions and self-reported behaviour (Total: N = 5631, Austria: N = 731, Switzerland: N = 698, Germany: N = 711, France: N = 708, Italy: N = 695, Poland: N = 693, Sweden: N = 682, UK: N = 713). Across all countries, the lowest consumer familiarity was found for the meaning of the pictogram for "health hazard" (65% indicated having never seen it before). Small-sized differences between the eight countries were observed regarding people's familiarity, perceptions and self-reported behaviour. The results suggest that people apply hazard-related as well as product- and marketing-related strategies to judge the dangerousness of a chemical household product. These findings suggest a number of starting points for risk regulation and communication regarding hazardous household chemical products. Further, the results suggest that positive outcome expectancies and rules of thumb for judging the risks of a chemical household product are particularly relevant for people's self-reported safe use of chemical household products.

Cosmetics in use: a pharmacological review

Cosmetics" really comes from its utilization in Ancient Rome. They were commonly delivered by female slaves known as "cosmetae," which is the place "cosmetics" originated from. Cosmetics are utilized to upgrade appearance. Makeup has been around for a long time. The primary known individuals who utilized cosmetics to upgrade their beauty were the Egyptians. Makeup those days was simply basic eye shading or some material for the body. Presently a-days makeup assumes an imperative job for the two men and women. In developmental brain science, social challenge of appearance reinforces women's wants for perfect beauty. As indicated by "The Origin of Species", people have developed to exchange qualities to future ages through sexual determination that respects the body state of perfect beauty as astounding richness. Also, since women's beauty has as of late been viewed as an upper hand to make social power, a body that satisfies the social guidelines of a culture could accomplish restricted social assets. It's hard to believe, but it’s true, even men have turned out to be more beauty cognizant and are worried about their looks. Cosmetics can be delivered in the natural and hypoallergenic structure to fulfill the needs of clients. Makeup is utilized as a beauty help to help develop the self-esteem and certainty of a person. The significance of cosmetics has expanded the same number of individuals need to remain youthful and alluring. Cosmetics are promptly accessible today as creams, lipstick, scents, eye shadows, nail shines, hair showers and so forth. Different cosmetics like face powder offer gleam to the skin subsequent to applying the base cream. At that point we have lipsticks, which are connected by numerous women all things considered. They are produced using wax and cocoa butter in the ideal sum. Cosmetics like creams, gels, and colognes are utilized consistently by the two women and men. Creams go about as a chemical for the face as a rule. All the more as of late enemy of maturing creams have been made which can hold more youthful looking skin for a long time. The best cleansing specialists are cleansing cream, cleanser and water. Cosmetic creams fill in as skin sustenance for hard, dry and dry skin. It fundamentally greases up, diminishes and expels undesirable earth from the skin. Some famous fat creams that are utilized incorporate Vaseline and Lanolin. Dry creams are utilized in the assembling of cleanser and gelatin which is utilized as a base for the skin. Hair care has turned out to be one of the quickest creating markets in the beauty business. Numerous young fellows swing to oils and gels to keep up and style their hair. Items like hair gels, oils, and moisturizers have been acquainted in the market with assistance ensure hair fall and dandruff. A few callings, similar to the entertainment biz industry, center on the significance of the external appearance. Numerous identities and craftsmen have used makeup to beat the brutal lights and the glare of camera flashes. They know the significance of their looks and keep up them by utilizing an assortment of cosmetics. Their appearance is their most profitable resource and they accept each undertaking to show up as the fans need them to show up. Late research has demonstrated that makeup helps in assurance from destructive beams of the sun. Numerous beauty items producers have used the necessities of individuals to shield themselves and their skin from the beams of the sun. This is an extraordinary achievement on the grounds that prior make up and sun assurance could not mix together. Today Cosmetics help to upgrade our appearance and make us feel increasingly certain. With more cosmetics available today than any other time in recent memory, it ends up clear to us that they assume an extraordinary job in our regular daily existence (Figure 1).

Consumer behaviour survey for assessing exposure from consumer products: a feasibility study

Evaluating chemical exposures from consumer products is an essential part of chemical safety assessments under REACH and may also be important to demonstrate compliance with consumer product legislation. Modelling of consumer exposure needs input information on the substance (e.g. vapour pressure), the product(s) containing the substance (e.g. concentration) and on consumer behaviour (e.g. use frequency and amount of product used). This feasibility study in Germany investigated methods for conducting a consumer survey in order to identify and retrieve information on frequency, duration, use amounts and use conditions for six example product types (four mixtures, two articles): hand dishwashing liquid, cockpit spray, fillers, paints and lacquers, shoes made of rubber or plastic, and ball-pens/pencils. Retrospective questionnaire methods (Consumer Product Questionnaire (CPQ), and Recall-Foresight Questionnaire (RFQ)) as well as protocol methods (written reporting by participants and video documentation) were used. A combination of retrospective questionnaire and written protocol methods was identified to provide valid information in a resource-efficient way. Relevant information, which can readily be used in exposure modelling, was obtained for all parameters and product types investigated. Based on the observations in this feasibility study, recommendations are given for designing a large consumer survey.

Consumers' Risk Perception of Household Cleaning and Washing Products

A large share of accidental and nonaccidental poisonings are caused by household cleaning and washing products, such as drain cleaner or laundry detergent. The main goal of this article was to investigate consumers' risk perception and misconceptions of a variety of cleaning and washing products in order to inform future risk communication efforts. For this, a sorting task including 33 commonly available household cleaning and washing products was implemented. A total of 60 female consumers were asked to place the cleaning and washing products on a reference line 3 m in length with the poles "dangerous" and "not dangerous." The gathered data were analyzed qualitatively and by means of multidimensional scaling, cluster analysis, and linear regression. The dimensionality of the sorting data suggests that both analytically (i.e., written and graphical hazard notes and perceived effectiveness) and intuitively driven risk judgments (i.e., eco vs. regular products) were applied by the participants. Furthermore, results suggest the presence of misconceptions, particularly related to consumers' perceptions of eco cleaning products, which were generally regarded as safer than their regular counterparts. Future risk communication should aim at dispelling these misconceptions and promoting accurate risk perceptions of particular household cleaning and washing products.

Cleaning products, environmental awareness and risk perception in Mérida, Mexico

Cleaning products are associated with many health and environmental problems. Contamination of water resources by cleaning products is more likely to occur with septic tanks as sewage treatment systems especially in karstic terrains. We explored women’s ideas about water sources and the risk cleaning products pose to health and sewage in Mérida, a city in the Yucatán peninsula of Mexico. Women were unaware of the city’s water management system. We found a positive and statistically significant association between risk perception and environmental awareness, education level and employment status. We suggest developing education and risk communication strategies to inform residents about the hydro-geological features in the Yucatán, the vulnerability of its karstic aquifer and the health and environmental risks associated with cleaning agents.

Inhalation exposure to cleaning products: application of a two-zone model

In this study, modifications were made to previously applied two-zone models to address important factors that can affect exposures during cleaning tasks. Specifically, we expand on previous applications of the two-zone model by (1) introducing the source in discrete elements (source-cells) as opposed to a complete instantaneous release, (2) placing source cells in both the inner (near person) and outer zones concurrently, (3) treating each source cell as an independent mixture of multiple constituents, and (4) tracking the time-varying liquid concentration and emission rate of each constituent in each source cell. Three experiments were performed in an environmentally controlled chamber with a thermal mannequin and a simplified pure chemical source to simulate emissions from a cleaning product. Gas phase concentration measurements were taken in the bulk air and in the breathing zone of the mannequin to evaluate the model. The mean ratio of the integrated concentration in the mannequin's breathing zone to the concentration in the outer zone was 4.3 (standard deviation, σ = 1.6). The mean ratio of measured concentration in the breathing zone to predicted concentrations in the inner zone was 0.81 (σ = 0.16). Intake fractions ranged from 1.9 × 10(-3) to 2.7 × 10(-3). Model results reasonably predict those of previous exposure monitoring studies and indicate the inadequacy of well-mixed single-zone model applications for some but not all cleaning events.

High burden of musculoskeletal conditions: a problem that has only recently come to recognition

OBJECTIVES

Musculoskeletal conditions have only recently been acknowledged and research on their burden is scarce in the Middle East and North African (MENA) region. For the first time, a population based study was conducted in Lebanon to assess the prevalence, level of disability, and health seeking behaviours related to musculoskeletal pain and rheumatic disorders.

METHODS

A random sample of 500 participants aged ≥ 15 years from Southern Lebanon was interviewed using the COPCORD (Community Oriented Program for Control of Rheumatic Diseases) questionnaire.

RESULTS

The prevalence of current musculoskeletal pain was 31.2% [CI (27.0-35.2%)]. Being a female [OR=1.8, CI (1.2-2.8)] and of advancing age [OR=1.03, CI (1.01-1.05)] were the only significant factors associated with current musculoskeletal pain. Prevalence of current functional disability was 6.4% [CI (4.2-8.5%)]. Around quarter (26.0%) [CI (22.3-30.1%)] of our sample sought some kind of treatment. The overall prevalence rate of rheumatic disease was 17.0% [CI (13.7-20.3%)].

DISCUSSION

Our findings indicate that musculoskeletal conditions are common in Lebanon. This is a timely public health issue that needs further investigation and solid recognition by health authorities. Community-based interventions should target patients to prompt them to seek early help in order to prevent the development of musculoskeletal pain into disorders.

Hard work at home: musculoskeletal pain among female homemakers

This study explores the relationship between housework and musculoskeletal symptoms among homemakers, adjusting for social, demographic and economic factors. A cross-sectional survey was carried out on 435 women from Nabaa, a low-income community in Lebanon. In total, 77% of women reported having musculoskeletal pain in the previous 12 months. Both psychosocial and physical factors showed significant associations with musculoskeletal symptoms. Related psychosocial factors included feelings of stress associated with homemaking and homemakers' number of children and self-rated health. The physical factors associated with musculoskeletal pain were feeling fatigued at the end of a housework day, working long hours and working in awkward postures or frequently engaging in repetitive hand movements. Ergonomic stressors were also associated with pain in the back and upper and lower extremities. Women from this community engage in a large number of hours of housework that, alongside other factors, were associated with high prevalence of musculoskeletal pain.

PRACTITIONER SUMMARY

This study contributes to the literature by studying women's housework activities in association with musculoskeletal pain. The role of women in homemaking activities is explored together with physical exposures leading to reported symptoms. This study adds a perspective of a Middle Eastern context to the literature of women's musculoskeletal health.

Effect of women's perceptions and household practices on children's waterborne illness in a low income community

An ecosystem approach to human health was adopted in a community-based study carried out in Bebnine, an underserved town in Lebanon. The objective of the study is to examine the association between women's household practices and diarrhea among children in a setting where contaminated drinking water and intestinal diseases are common. A total of 280 women were randomly selected and interviewed using a structured questionnaire. Data were collected on 712 children between the ages of 6 and 14. The study instrument included determinants of diarrhea such as sociodemographic characteristics, water, sanitation, hygiene practices, gender variables, and behavioral risk factors. Multivariate regression analysis was employed to examine the association between water handling practices and diarrhea. The prevalence of diarrhea is 5%. Female children are more likely to suffer from diarrhea than male children (OR = 2.58; 95% CI: 1.19-5.62). Treatment of drinking water at the household level and the use of drinking water for cooking and the preparation of hot beverages are protective against diarrhea (OR = 0.15; 95% CI: 0.03-0.65). Female caretakers' behaviors such as daily bathing and seeking medical care at times of illness are protective against diarrhea in children. The findings suggest that diarrhea is a gendered health problem. Female children, who are generally more involved in household activities than male children, are at higher risk of suffering from diarrhea. Female caretakers' personal hygiene, household practices, and perceptions of diarrhea are additional risk factors. Intervention activities would be more effective if based on a better understanding of gender roles and household power relations.

Volatile pollutants emitted from selected liquid household products

BACKGROUND, AIM, AND SCOPE

To identify household products that may be potential sources of indoor air pollution, the chemical composition emitted from the products should be surveyed. Although this kind of survey has been conducted by certain research groups in Western Europe and the USA, there is still limited information in scientific literature. Moreover, chemical components and their proportions of household products are suspected to be different with different manufacturers. Consequently, the current study evaluated the emission composition for 42 liquid household products sold in Korea, focusing on five product classes (deodorizers, household cleaners, color removers, pesticides, and polishes).

MATERIALS AND METHODS

The present study included two phase experiments. First, the chemical components and their proportions in household products were determined using a gas chromatograph and mass spectrometer system. For the 19 target compounds screened by the first phase of the experiment and other selection criteria, the second phase was done to identify their proportions in the purged-gas phase.

RESULTS

The number of chemicals in the household products surveyed ranged from 9 to 113. Eight (product class of pesticides) to 17 (product class of cleaning products) compounds were detected in the purged-gas phase of each product class. Several compounds were identified in more than one product class. Six chemicals (acetone, ethanol, limonene, perchloroethylene (PCE), phenol, and 1-propanol) were identified in all five product classes. There were 13 analytes occurring with a frequency of more than 10% in the household products: limonene (76.2%), ethanol (71.4%), PCE (66.7%), phenol (40.5%), 1-propanol (35.7%), decane (33%), acetone (28.6%), toluene (19.0%), 2-butoxy ethanol (16.7%), o-xylene (16.7%), chlorobenzene (14.3%), ethylbenzene (11.9%), and hexane (11.9%). All of the 42 household products analyzed were found to contain one or more of the 19 compounds.

DISCUSSION

The chemical composition varied broadly along with the product classes or product categories, and it was different from that reported in other studies abroad, although certain target chemicals were identified in both studies. This finding supports an assertion that chemical components emitted from household products may be different in different products and with different manufacturers. The chlorinated pollutants identified in the present study have not been reported to be components of cleaning products in papers published since the early 1990s. Limonene was identified as having the highest occurrence in the household products in the present study, although it was not detected in any of 67 household products sold in the U.S.

CONCLUSIONS

The emission composition of selected household products was successfully examined by purge-and-trap analysis. Along with other exposure information such as use pattern of household products and the indoor climate, this composition data can be used to estimate personal exposure levels of building occupants. This exposure data can be employed to link environmental exposure to health risk. It is noteworthy that many liquid household products sold in Korea emitted several toxic aromatic and chlorinated organic compounds. Moreover, the current finding suggests that product types and manufacturers should be considered, when evaluating building occupants' exposure to chemical components emitted from household products.

RECOMMENDATIONS AND PERSPECTIVES

The current findings can provide valuable information for the semiquantitative estimation of the population inhalation exposure to these compounds in indoor environments and for the selection of safer household products. However, although the chemical composition is known, the emissions of household products might include compounds formed during the use of the product or compounds not identified as ingredients by this study. Accordingly, further studies are required, and testing must be done to determine the actual composition being emitted. Similar to eco-labeling of shampoos, shower gels, and foam baths proposed by a previous study, eco-labeling of other household products is suggested.

Head-space, small-chamber and in-vehicle tests for volatile organic compounds (VOCs) emitted from air fresheners for the Korean market

The present study investigated the emission characteristics of gel-type air fresheners (AFs), using head-space, small-chamber, and in-vehicle tests. Five toxic or hazardous analytes were found in the headspace phase of AFs (toluene, benzene, ethyl benzene, and m,p-xylene) at a frequency of more than 50%. Limonene and linalool, which are known to be unsaturated ozone-reactive VOCs, were detected at a frequency of 58 and 35%, respectively. The empirical model fitted well with the time-series concentrations in the chamber, thereby suggesting that the empirical model was suitable for testing emissions. Limonene exhibited the highest emission rate, followed by m,p-xylene, toluene, ethyl benzene, and benzene. For most target VOCs, higher air change per hour (ACH) levels exhibited increased emission rates. In contrast, higher ACH levels resulted in lower chamber concentrations. The mean concentration of limonene was significantly higher in passenger cars with an AF than without. For other target compounds, there were no significant differences between the two conditions tested. Consequently, it was suggested that unlike limonene, the emission strength for aromatic compounds identified in the chamber tests was not strong enough to elevate in-vehicle levels.

Characterization of emissions composition for selected household products available in Korea

The present study investigated the emission composition for 59 household products currently sold in Korea, using a headspace analysis. The chemical composition and concentrations of total volatile organic compounds (VOCs) broadly varied along with products, even within the same product category. Up to 1-17 organic compounds were detected in the headspace gas phase of any one of the products. The chemical composition of certain household products determined in the current study was different from that of other studies from other countries. Between 4 and 37 compounds were detected in the headspace gas phase of each product class. Several compounds were identified in more than one product class. Of the 59 household products analyzed, 58 emitted one or more of the 72 compounds at chromatographic peak areas above 10(4). There were 11 analytes which occurred with a frequency of more than 10%: limonene (44.2%), ethanol (30.5%), acetone (18.6%), alpha-pinene (18.6%), o,m,p-xylenes (18.6%), decane (17.0%), toluene (17.0%), beta-myrcene (11.9%), ammonia (10.2%), ethylbenzene (10.2%), and hexane (10.2%).
