“…The process of assessing risk to humans of household products entails a sequence of actions relevant to human health, such as identification of hazardous substances in products, characterization of these substances, exposure assessment, and risk characterization (ECHA, 2012(ECHA, , 2013(ECHA, , 2016. The current study investigated the exposure database of single-use patterns and reliable exposure factors concerning household products (Kim et al, 2019). The current study provides data on the couse and multiple use of 11 household products and 40 uses of 11 products.…”

“…This study analyzed the co-use and multiple-use pattern of 11 household products collected from survey study of 6,397 respondents that carried was out over two years (2016−2017) in 15 metropolitan areas and provinces including rural areas in Korea (Kim et al, 2019). The previous study investigated a national exposure factor database to be used in exposure assessment and risk assessment of household products to human health.…”

“…Reference reliable exposure factors of Korean consumers were already established by the NIER (KNLIC, 2017(NIER, No. 2017; Kim et al, 2019). Reference exposure factors for household products consists of the frequency of use, the duration of use, and the amounts of use per application divided by usages and their application types.…”

To accurately evaluate the health risk of consumers from the combined effects of substances in multiple used household products, data on co-use and multiple-use habits and practices of consumers necessarily constitute a fundamental element of the exposure assessment process. To understand the current combined use pattern of household products, reliable combined exposure data were investigated. Eleven household product categories were selected and divided by 40 product use purposes. This approach analyzed the information of single-use, co-use, and multipleuse patterns of the 11 products at home collected from 6,397 respondents. All possible multiple combinations of products and product usage categories were analyzed. As expected, the participants used several products and product usage categories simultaneously. The data yielded important personalized combined exposure patterns that can be used in exposure assessment for hazardous substances that are used as ingredients of products. Furthermore, this study investigated the combined exposure amount of 11 products to user at home. Aggregate exposure amount per month to user was calculated to be 7479.6 g/month (six products in 1 st survey) and 4056 g/month (five products in 2 nd survey). This study provides valuable information on the individual use patterns and circumstances of household product use by consumers. b 107 (multiple-users: DEP, IAP, ARP, TIP) c 281 (co-users: IAP, TIP) b 116 (multiple-users: IAP, ARP, TIP) c 445 (co-users: ARP, TIP) b 2030 aAFP, air-freshener; DEP, deodorant; IAP, ironing auxiliary; ARP, algea remover; TIP, toner and ink cartridge in printer. a numbers of respondents using single product, b numbers of respondents using two products, c numbers of respondents using multiple products.

“…In this study, eight product groups were selected on the basis of their frequency of use; the target household products have been established by the Korean Ministry of Environment (KMOE) as products of concern based on risks to residential consumers (Table 1) [29]. According to the results of our previous study [25], the web survey questionnaires were used to determine combined exposure to household products by the studied families, and were divided as follows: (1) information on the retention and use of products, namely lists of retained target products, amounts of retained products, product use/purchase periods, and qualitative descriptions of product co-use habits; and (2) information on demographics, namely ages of family members, average time spent indoors for each member (separately for working and non-working days), occupation (employed, unemployed, student, housewife, or other), type of house, and average house size. Single-product-use exposure data were obtained from national survey data (Korean consumer exposure factors to household products) [26].…”

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.
