Yoon H, Kim TH, Lee BC, Lee B, Kim P, Shin BS, Choi J. Comparison of the exposure assessment of di(2-ethylhexyl) phthalate between the PBPK model-based reverse dosimetry and scenario-based analysis: A Korean general population study. CHEMOSPHERE 2022; 294:133549. [PMID: 35066077 DOI: 10.1016/j.chemosphere.2022.133549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 01/04/2022] [Accepted: 01/04/2022] [Indexed: 06/14/2023]
Abstract
Di (2-ethylhexyl) phthalate (DEHP), classified as a reproductive toxicant, is a ubiquitous pollutant in foodstuffs, dust, and commercial products. In this study, to provide a useful cross-check on the accuracy of the exposure assessment, the estimated daily intake of DEHP was compared using reverse dosimetry with a physiologically-based pharmacokinetic (PBPK) model and a scenario-based probabilistic estimation model for six subpopulations in Korea. For reverse dosimetry analysis, the concentrations of urinary DEHP metabolites, namely mono (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and mono (2-ethyl-5-oxohexyl)phthalate (MEOHP), from three human biomonitoring program datasets were used. For the scenario-based model, we evaluated the various exposure sources of DEHP, including diet, air, indoor dust, soil, and personal care products (PCPs), and also determined its levels based on the literature review and measurements of indoor dust. The DEHP exposure doses using both exposure assessment approaches were similar in all cases, except for the 95th percentile exposure doses in toddlers (1-2 years) and young children (3-6 years). The PBPK-reverse dosimetry estimated daily intakes at the 95th percentile ranged between 22.53 and 29.90 μg/kg/day for toddlers and young children. These exceeded the reference dose (RfD) of 20 μg/kg bw/day of the US Environmental Protection Agency (EPA) based on the increased relative liver weight. Although, food was considered the primary source of DEHP, contributing to a total exposure of 50.8-75.1%, the effect of exposure to indoor dust should not be overlooked. The occurrence of high levels of DEHP in indoor dust collected from Korean homes suggests the use of a wide variety of consumer products containing DEHP. Furthermore, more attention should be paid to the high exposure levels of DEHP, especially in young children. Therefore, it is necessary to perform continuous monitoring of the indoor dust, consumer products, and the body burden of children.

Abstract
Exposure to environmental chemicals during early childhood is a potential health concern. At a tender age, children are exposed to fragrance chemicals used in toys and child care products. Although there are few initiatives in Europe and United States towards monitoring and regulation of fragrance chemicals in children's products, such efforts are still lacking elsewhere. Besides there has been no systematic effort to create a database compiling the surrounding knowledge on fragrance chemicals used in children's products from published literature. Here, we built a database of Fragrance Chemicals in Children's Products (FCCP) that compiles information on 153 fragrance chemicals from published literature. The fragrance chemicals in FCCP have been classified based on their chemical structure, children's product source, chemical origin and odor profile. Moreover, we have also compiled the physicochemical properties, predicted Absorption, Distribution, Metabolism, Excretion and Toxicity (ADMET) properties, molecular descriptors and human target genes for the fragrance chemicals in FCCP. After building FCCP, we performed multiple analyses of the associated fragrance chemical space. Firstly, we assessed the regulatory status of the fragrance chemicals in FCCP through a comparative analysis with 21 chemical lists reflecting current guidelines or regulations. We find that several fragrance chemicals in children's products are potential carcinogens, endocrine disruptors, neurotoxicants, phytotoxins and skin sensitizers. Secondly, we performed a similarity network based analysis of the fragrance chemicals in children's products to reveal the high structural diversity of the associated chemical space. Lastly, we identified skin sensitizing fragrance chemicals in children's products using ToxCast assays. In a nutshell, we present a comprehensive resource and detailed analysis of fragrance chemicals in children's products highlighting the need for their better risk assessment and regulation to deliver safer products for children. FCCP is accessible at: https://cb.imsc.res.in/fccp.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 782:146829. [PMID: 33838372 DOI: 10.1016/j.scitotenv.2021.146829] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 03/23/2021] [Accepted: 03/25/2021] [Indexed: 06/12/2023]
Abstract
Preservatives are essential additives in dishwashing detergents and wet wipes. Ensuring the safe use of preservatives in products is important for public health, as some preservatives are associated with health issues. In this study, the content of 12 preservatives in 105 dishwashing detergents and 105 wet wipes was determined, where these compounds are commonly found, among consumer products. A realistic exposure estimation was considered by using Korean consumer-specific exposure parameters for adults and babies. A probabilistic risk assessment was conducted by applying the Monte Carlo simulation method. Benzoic acid (41%) and cetylpyridinium chloride (30%) were the most commonly used preservatives in dishwashing detergents and wet wipes, respectively, although their content in different products (benzoic acid: 0.28-19.4 mg/g in dishwashing detergents; cetylpyridinium chloride: 0.003-0.64 mg/g in wet wipes) varied widely. The calculated median and upper-limit margin of safety (MOS) values related to systemic health effects and skin sensitization from exposure to preservatives largely exceeded the target MOS, which confirmed the safety of the products. Exposure to preservatives from wet wipes was several times higher in babies than in adults. Sensitivity analysis revealed that the amount of the product used, frequency of use, and weight fraction of the preservative were the major contributors to the exposure to preservatives from dishwashing detergents and wet wipes.

Abstract
Many consumer products are manufactured or synthesized from chemicals. However, consumers may be hesitant to purchase consumer products that are perceived as synthetic or derived with chemical substances. Prior studies suggested a preference for chemicals of natural origin and an irrational fear of synthetic chemicals, a phenomenon that is referred to as chemophobia. The aim of this study was two-fold as follows: to (1) investigate the levels of knowledge with respect to toxicological principles, chemophobia, and trust in stakeholders in South Korea and (2) experimentally test the effect of information provision on acceptance and willingness-to-buy for the specific case of trace chemicals in consumer products. For this purpose, an online survey and experiment was conducted with consumers in South Korea. Data suggested that in South Korea chemophobia correlated with an individual's knowledge regarding toxicological principles. Accordingly, a small intervention providing information on the dose-response mechanism increased consumers' acceptance of the presence of trace chemicals and subsequent willingness to purchase the products in this study. In conclusion, this investigation stresses the importance of educating the public regarding basic principles of toxicology to avoid chemophobia, while simultaneously discussing other factors that need to be taken into account such as attitudes and trust in communicators.

Abstract
Olfactory receptors (ORs) are a group of G protein coupled receptors (GPCRs) that initiate chemical odorant signals. Although ORs are predominantly located in nasal epithelia to detect smell, these receptors are also present in peripherally in non-nasal organs/tissues. Since the quality of life and cognitive and sensorial features of sense of smell are worsened in multiple chemical sensitivity due to the interaction of ORs with offending compounds, it is important to not only differentiate these receptors from other GPCRs but also characterize these organelles to understand the underlying mechanisms of smelling disorders. The aim of this study was develop computerized programs to differentiate ORs from GPCRs. The computer program was developed on the basis of widely accepted basic algorithms. It is noteworthy that an accuracy of 95.5% was attained, a level not achieved using other established techniques for screening of ORs from GPCRs. The high accuracy rate indicates that this method of differential identification appears reliable. Our findings indicate that this novel method may be considered as a tool for identification and characterization of receptors which might aid in therapeutic approaches to human chemical-mediated sensitization.

Abstract
Olfactory receptor (OR) genes are extensively distributed throughout the human organism. Although these receptors are predominantly located in the olfactory epithelium, binding between odorant chemicals and corresponding ORs initiates downstream events in other tissues. In particular, exposure to allergen fragrances results in the induction of contact dermatitis. At present, current methodologies are limited in their ability to predict the consequences of fragrancy chemicals on humans. The aim of this study was designed to simulate the bindingstructure between lyral and OR10J5, a known allergen which produces contact dermatitis, and its corresponding OR OR10J5 in an effort to predict dermal outcomes using computational methods. Results demonstrated that binding between lyral and OR10J5 involved amino acid residues Phe104, Val105, Cyx178, Ile180, and Tyr258, respectively, which were located on binding sites of the receptor transmembrane 3(TM3), TM3, extracellular loop 2(EL2), EL2, TM6. Evidence indicates that computer simulating binding interactions occurred between an odorant chemical and its receptors which initiated downstream alterations accounting possibly for the observed in vivo contact dermatitis.

Abstract
Olfactory receptor 5P3 is coded by OR5P3 gene in human OR5P3 and recognized as the receptor for coumarin present in 30% of fragrances and might adversely affect human health. OR5P3 are also associated with coumarin-related breast cancer development and acquired tamoxifen resistance in breast cancer cells. Previously various investigators noted that coumarin acts as a ligand for OR5P3 and binding of this molecule to OR5P3 leads to downstream changes in the olfactory bulb and central nervous system. However, the interaction between OR5P3 and its ligands at molecular level is not well understood. The aim of this study was to develop a computerized approach to simulate the binding process of coumarin to OR5P3 and determine the binding sites at a molecular level. It is conceivable that understanding this binding mechanism to a specific OR may aid in identification of receptors responsible olfaction and non-olfaction disorders such as breast cancer. The approach employed in this study may thus be utilized in future studies to simulate bind of specific chemicals to ORs and potentially have therapeutic applications.

Abstract
Understanding how indoor-air contaminants affect human health is of critical importance in our developed society. We assessed the combined exposure by inhalation of preschool children and children to household products. A total of 1175 families with 72 infants, 158 toddlers, 230 children, and 239 youths were surveyed to determine the combined respiratory exposure concentrations and amounts associated with 21 substances in eight household product groups. We determined the mean concentrations of these substances in each product, and derived reference toxicity values based on the information gathered in order to identify respiratory health risks. On average, cleaners were used at a rate of 1.0 × 10³ g/month, while coating agents and other substances were used at 43 g/month. The combined inhalation exposure concentrations of methanol to infants and toddlers were 5.1 and 4.2 mg/m³ per month, respectively, with values of 2.1 and 1.7 mg/m³ for isopropanol, respectively. Risks to preschool children and children should be assessed on the basis of the toxicity values of combined exposed hazardous substances, as well as their combined concentrations and amounts. This exposure assessment approach can be used to establish improved guidelines for products that may pose inhalation hazards to preschool children and children.

Abstract
Exposure assessment, a fundamental element of the risk assessment process, is the estimation of what consumers may be exposed to by using household products. Reliable exposure factors were investigated to understand the pattern of household products usage. Six household product categories were selected and divided by application types. Two surveys were carried out and 6397 participants completed the web-based questionnaires, and laboratory evaluations were also conducted to measure the actual level of exposure (g/use). We focused more on inhalation exposure from products (and/or their application types) that affect indoor air such as diffusible types. To estimate actual exposure amounts, the time spent to apply the products was investigated from the beginning to end of the product use. For spraying type products, the consumer could be exposed to the maximum amount of used product while using the triggering action and pressing the button on the aerosol spray product, and during cleaning, adhesion, and coating target, consumer could be exposed continuously. For diffuser type products, exposure duration was the time for which consumers were exposed to the diffused product. The exposure amount for trigger and aerosol spray type products were measured using the time taken to trigger or spray the product and the mass generated from the same. This study provides valuable information on the individual exposure factors that may be useful to conduct accurate exposure assessments and to manage household products.

Abstract
Cutaneous allergy occurs primarily as a result of using cosmetic, household, and laundry products available on the market that contain fragrances. The aim of this study was to develop a rapid and specific high-performance liquid chromatography with ultraviolet detection (HPLC-UV) method for quantification of 25 fragrance allergens (amyl cinnamyl alcohol, benzyl alcohol, benzyl benzoate, benzyl cinnamate, benzyl salicylate, citronellol, cinnamyl alcohol, citral, coumarin, eugenol, farnesol, geraniol, hydroxycitronellal, HICC (4-(4-hydroxy-4-methylpentyl)-3-cyclohexene-1-carboaldehyde), isoeugenol, isoeugenyl acetate, lilial (butyl phenyl methyl propional), limonene, linalool, methyl 2-octynoate, etc.). In addition, an exposure-based quantitative risk assessment (QRA) was performed to determine safe levels of fragrance ingredients in 107 perfumes. In 76 women's and 31 men's fragrances, 25 allergens were identified at concentrations ranging from undetectable (N.D.) to 8,997.68 mg/kg, and from N.D. to 17,352.34 mg/kg, respectively. An exposure-based sensitization QRA revealed that the ratios of acceptable exposure level (AEL) to consumer exposure level (CEL) of fragrance ingredients were greater than 1, suggesting an absence of skin sensitizing potential. However, the maximum level used in the exposure scenario was determined by the product purpose and application type, and AEL/CEL ratios of lilial, HICC, citral, isoeugenol, and methyl 2-octynoate analyzed in women's perfume were 0.53, 0.67 0.19, 0.13, and 0.57, respectively. As the ratios of AEL:CEL of these fragrance ingredients were below 1, the utilization of these potential skin sensitizers is not considered safe. Our findings indicate that the sensitization risk of allergens with AEL:CEL ratios below 1 detected in fragrances needs to be reduced to the appropriate human safety level for risk management.
