Exposure to airborne methacrylates in nail salons

Assessing occupational exposure of airborne PMs and TVOCs in the nail salons in Tehran city, Iran

There are concerns about the health of nail salon technicians due to the inherently harmful agents such as volatile organic compounds (VOCs) and released particles in the salons. For this reason, this study was conducted to investigate the occupational exposure of nail salon technicians to VOCs and particulate matters (PMs) in the nail salons in Tehran, Iran. In this cross-sectional study, indoor air quality and measurement continually Total VOCs and PMs in the various size of PM1-PM10 using PhoCheck Tiger and particle counter device investigated, respectively. site observation, and an interview with the manager in 49 salons in Tehran. Data was analyzed using SPSS software (version 22). Mean concentrations of PM1 with 2.56 μɡ/m3 was the lowest amount and PM10 with 346.86μɡ/m3 had the highest concentration. Also, the mean concentration of TVOCs was equal 2.61 ppm. The results of the regression model showed that there is a statistically significant between the number of services with airborne PMs (PM2.5), (p-Value≤0.050). In salons only with nail activities, the concentration of PM4 was less than the others, although this correlation was statistically significant just for PM1 (p-Value = 0.010). By implementing effective local exhaust ventilation systems equipped with dust collectors and utilizing safe products, the emission of particles and chemical compounds within salons can be significantly reduced.

Challenges in the classification of chemical respiratory allergens based on human data: Case studies of 2-hydroxyethylmethacrylate (HEMA) and 2-hydroxypropylmethacrylate (HPMA)

Occupational asthma resulting from workplace exposure to chemical respiratory allergens is an important disease. No widely accepted or formally validated tests for the identification of chemical respiratory sensitizers. Consequently, there is a heavy reliance on human data from clinical examinations. Unfortunately, however, although such investigations are critical for the diagnosis of occupational asthma, and in guiding remedial actions, they do not reliably identify specific chemicals within the workplace that are the causative agents. There are several reasons for this, including the fact that specific inhalation tests conducted as part of clinical investigations are frequently performed with complex mixtures rather than single substances, that sometimes inhalation challenges are conducted at concentrations above the OEL and STEL, where effects may be confounded by irritation, and that involvement of immune mechanisms cannot be assumed from the observation of late asthmatic reactions. Further, caution should be taken when implicating substances on lists of "recognised" asthmagens unless they have undergone a formal weight of evidence assessment. Here the limitations of clinical investigations as currently performed for the purposes of regulatory classification and decision making are explored by reference to previously published case studies that implicate 2-hydroxyethylmethacrylate (HEMA) and/or 2-hydroxypropylmethacrylate (HPMA) as respiratory allergens.

Characterizing Occupational Health Risks and Chemical Exposures Among Asian Nail Salon Workers on the East Coast of the United States

The products used in nail care services contain toxic chemicals. This study aimed to characterize occupational health risk factors and chemical exposures among Asian nail salon workers on the East Coast of the U.S. for informing the development of more effective, culturally appropriate interventions. We conducted a community-based participatory research (CBPR) study to characterize occupational health risks. A face-to-face, self-reported survey was performed, and personal exposure to volatile organic compounds (VOCs) was evaluated. Three VOCs, acetone, methyl methacrylate (MMA), and toluene, were measured using 3M 3500 organic vapor monitors. We collected data on 112 workers with 100 personal chemical exposure measurements from 25 nail salons. Self-reported health problems that emerged or worsened after participants started working in the nail salon industry included headaches (8%); lightheadedness (9.8%); and irritation to the nose, eyes, throat, and skin (21.2%). Approximately 70% of participants reported that they had been pregnant, 11.7% of whom had at least one miscarriage. The mean concentrations of acetone, MMA, and toluene were 18.51 parts per million (ppm), 39.45 ppm, and 0.09 ppm, respectively. Mean concentrations of acetone and MMA measured from salons in New York City were significantly lower than those measured in Philadelphia and southern New Jersey. CBPR proved to be as an efficient approach for recruiting hard-to-reach Asian immigrant nail salon workers. Adverse health symptoms and problems associated with providing nail salon services were identified in these workers. Further studies are needed to better understand the long-term health effects of chronic chemical exposures in nail salon environments.

"Worrying About Getting Sick in the Future": Lived Experience of Health Seeking and Healthcare Utilization Among Korean Immigrant Nail Salon Workers

To understand the health and safety concerns of Korean immigrant women nail salon workers in the Greater New York City area and their experiences of health seeking and health service utilization, 20 semi-structured interviews were conducted and analyzed using interpretive hermeneutic phenomenology. Most worried about working in nail salons and experienced work-related health symptoms. However, they were disinclined toward personal protective device use because of discomfort and inconvenience. Major barriers to healthcare utilization limited their healthcare use to times when they had intolerable symptoms, preventing opportunities for regular screening tests. To overcome these limitations, workers actively sought available resources and health-related information online and through personal networks, the latter facilitated by living in a Korean community. Despite efforts to maintain their health and manage their symptoms, Korean nail salon workers worried about getting sick as they got older due to prolonged occupational chemical exposure and limited healthcare access. Appropriate education and intervention should aim to resolve current barriers to personal protective device use and healthcare use and provide a source of care for uninsured workers.

Phenotyping Occupational Asthma Caused by Acrylates in a Multicenter Cohort Study

BACKGROUND

While acrylates are well-known skin sensitizers, they are not classified as respiratory sensitizers although several cases of acrylate-induced occupational asthma (OA) have been reported.

OBJECTIVE

To evaluate the characteristics of acrylate-induced OA in a large series of cases and compare those with OA induced by other low-molecular-weight (LMW) agents.

METHODS

Jobs and exposures, clinical and functional characteristics, and markers of airway inflammation were analyzed in an international, multicenter, retrospective cohort of subjects with OA ascertained by a positive inhalation challenge to acrylates (n = 55) or other LMW agents (n = 418) including isocyanates (n = 125).

RESULTS

Acrylate-containing glues were the most prevalent products, and industrial manufacturing, dental work, and beauty care were typical occupations causing OA. Work-related rhinitis was more common in acrylate-than in isocyanate-induced asthma (P < .001). The increase in postchallenge fractional exhaled nitric oxide was significantly greater in acrylate-induced OA (26.0; 8.2 to 38.0 parts per billion [ppb]) than in OA induced by other LMW agents (3.0; -1.0 to 10.0 ppb; P < .001) or isocyanates (5.0; 2.0 to 16.0 ppb; P = .010). Multivariable models confirmed that OA induced by acrylates was significantly and independently associated with a postchallenge increase in fractional exhaled nitric oxide (≥17.5 ppb).

CONCLUSIONS

Acrylate-induced OA shows specific characteristics, concomitant work-related rhinitis, and exposure-related increases in fractional exhaled nitric oxide, suggesting that acrylates may induce asthma through different immunologic mechanisms compared with mechanisms through which other LMW agents may induce asthma. Our findings reinforce the need for a reevaluation of the hazard classification of acrylates, and further investigation of the pathophysiological mechanisms underlying their respiratory sensitizing potential.

Work-Related Symptoms, Safety Concerns, and Health Service Utilization Among Korean and Chinese Nail Salon Workers in the Greater New York City Area

The purpose of this study was to determine similarities and differences in health effects, safety concerns, and health service utilization among Korean and Chinese immigrant women working in nail salons in the Greater New York City area. In this cross-sectional study, analyses involved descriptive statistics, t tests, and χ2 tests. Koreans had longer work experience and more work-related health effects and concerns, but were less likely to use personal protective equipment than Chinese workers. Although Koreans reported better socioeconomic status than Chinese workers, they were less likely to have health care access and utilized less health services. To prevent prolonged exposure to toxic chemicals, nail salon employees need education regarding the importance of personal protective equipment use. Reducing structural barriers and increasing health care access for all nail salon workers are especially important in improving their health service utilization.

Factors Influencing Health Service Utilization Among Asian Immigrant Nail Salon Workers in the Greater New York City Area

Most nail salon workers in the greater New York City area are Asian immigrant women. They are exposed daily to potentially toxic chemicals and hazards in their workplace, making them more vulnerable for possible health problems. The study's primary purpose was to identify factors influencing past year healthcare utilization among Asian immigrant women working in nail salons. A cross-sectional study was conducted based on a modification of Andersen's behavioral model of healthcare utilization in which 148 Korean and Chinese immigrant women currently working in nail salons were surveyed. The questionnaire included: (1) individual health determinants, (2) health service utilization in the past year, and (3) work environment, work-related health concerns, and work-related health problems. Descriptive statistics and multivariate logistic regression models assessed factors related to past year healthcare utilization. Women who had health insurance (p < .01), a usual source of care (p < .01), low educational attainment (p < .05), and more work-related health symptoms (p < .05) were more likely to visit a primary care provider. Women who had health insurance (p < .01), a usual source of care (p < .05), and low educational attainment (p < .05), were also more likely to visit a woman's health provider. Korean (rather than Chinese) women (p < .05) and women who perceived themselves to be in fair/poor health (p < .05) were more likely to see a traditional provider of Eastern medicine. Asian immigrant women who work in nail salons have workplace health and safety concerns. They generally use Western rather than traditional medicine, with different factors related to these two types of medicine.

Indoor air quality survey of nail salons in Boston

Employees in nail salons, largely Vietnamese immigrant women in Boston, are exposed to a range of volatile organic chemicals from the products used in salons, including solvents, glues and polishes. Some of these chemicals have the potential to cause short and long-term adverse health effects. Only limited research has been performed on assessing occupational exposures. This project aimed to characterize total volatile organic compound (TVOC) and PM_2.5 concentrations in nail salons as a function of ventilation, building characteristics, customer and employee occupancy, and type of services being performed. Students conducted sampling in 21 salons in Boston, MA from September to December, 2011. Study visits included: indoor environmental quality measurements (TVOCs, PM_2.5 and carbon dioxide), site observations, and an interview. CO₂ levels in 15 of 21 salons exceeded 800 ppm, suggesting that these salons may have insufficient ventilation. Higher TVOC and PM_2.5 levels were found in salons with less ventilation (as estimated using CO₂ concentrations). Contrary to our a priori hypothesis, average levels of TVOCs, CO₂ and PM_2.5 were consistent throughout salons, indicating that exposures may not be restricted to areas in the salon where work is being performed (e.g., at the manicure table). Higher TVOC concentrations were observed when tasks were being performed, yet were not dependent upon the number of tasks being performed. Improving ventilation conditions in salons to meet minimum outdoor air delivery requirements can reduce exposures to TVOCs.

Identifying Health and Safety Concerns in Southeast Asian Immigrant Nail Salon Workers

Nail salon workers are exposed to a variety of toxic chemicals at levels that remain unreported and have undetermined health consequences. The objective of the study was to gather information about the hazards in nail salons along with safety practices and health concerns of nail salon workers. A survey was conducted on 65 nail salon workers who were immigrants from Southeast Asia in Oregon, USA. More than 20% of the participants reported nose irritation and allergies as the most common health problems. Rare and no use of gloves and mask were reported among 72% and 32% of the participants, respectively. A significantly higher number of participants with "fair" or "poor" self-reported general health condition was found among the workers who applied acrylic nails compared with those who were not involved in this application. Findings of the study emphasize the need for more research to determine the relationship between chemical exposures in nail salons and health outcomes.
