“…The VOCs from ARIs spraying often involve aromatics, halocarbons, ketones, alcohols, ethers, esters, acids and alkanes. Previous research mainly focused on the analysis of VOCs pollution sources (Hu et al 2022; Hu et al 2021), secondary organic aerosol (SOA) (Teng et al 2023) and ozone formation potential (OFP) (Jiang et al 2023). VOCs emissions resulted from tremendous growth in the use of spraying materials not only causes air pollution problems but also causes diseases (Chardon et al 2021).…”

The increasing automobile repair industries (ARIs) with spray facilities have become an important volatile organic compounds (VOCs) pollution source in China. However, the VOCs health risk assessment for long-term exposure in ARIs have not been well characterized. In this study, though sampled VOCs from 51 typical ARIs in Beijing, the relationship between emission patterns, average daily exposure concentrations (EC) and health risks were comprehensively analyzed with the health assessment method for spray operators, and the studies consider the health effects of the sprayers for ve processes due to the difference in raw materials. Results showed that oxygen VOCs (OVOCs) and aromatics were the main VOCs components in solvent-based and water-based workshops, respectively. And ARIs operator's daily VOCs inhalation EC was 11.24-1460.70 µg•m − 3 . The method of inhalation exposure health risk assessment was rstly used to evaluate carcinogenicity and non-carcinogenicity risk for sprayers in ARIs.The cumulative lifetime carcinogenic risk (LCR) for 24 sampled VOCs were within acceptable ranges, while the mean hazard index (HI) with 44 sampled VOCs was over 1. Among them, the LCR and HI of VOCs in solvent-based spraying workshops were 8.72E-12 to 5.66E-7 and 0.13 to 22.37, and ethanol had a high carcinogenic risk. Of these, the mean HI associated with aromatics were 6.45 to 9.64. Our study will provide the important references for the standard of VOCs occupational exposure health limits in ARIs.

The increasing automobile repair industries (ARIs) with spray facilities have become an important volatile organic compounds (VOCs) pollution source in China. However, the VOCs health risk assessment for long-term exposure in ARIs have not been well characterized. In this study, though sampled VOCs from 51 typical ARIs in Beijing, the relationship between emission patterns, average daily exposure concentrations (EC) and health risks were comprehensively analyzed with the health assessment method. Results showed that concentrations of 117 VOCs from the samples ranged from 68.53 to 19863.32 µg·m− 3, aromatics were the main VOCs component in mix paint (MP) workshops and water-based paint spraying (WPS) workshops, accounting for 44.00% and 70.08%, respectively. And ARIs operator's daily VOCs inhalation EC was 11.24-1460.70 µg·m− 3. The method of inhalation exposure health risk assessment was firstly used to evaluate carcinogenicity and non-carcinogenicity risk for sprayers in ARIs. The cumulative lifetime carcinogenic risk (LCR) for 24 sampled VOCs were within acceptable ranges, while the mean hazard index (HI) with 44 sampled VOCs was over 1. Among them, the LCR and HI of VOCs in solvent-based spraying workshops were 8.72E-12 to 5.66E-7 and 0.13 to 22.37, and ethanol had a high carcinogenic risk. Of these, the mean HI associated with aromatics were 6.45 to 9.64. Our study will provide the important references for the standard of VOCs occupational exposure health limits in ARIs.

In this study, though sampled VOCs from 51 typical ARIs in Beijing, the relationship between emission patterns, average daily exposure concentrations (EC) and health risks were comprehensively analyzed with the health assessment method for spray operators, and the studies consider the health effects of the sprayers for five processes due to the difference in raw materials. Results showed that oxygen VOCs (OVOCs) and aromatics were the main VOCs components in solvent-based and water-based workshops, respectively. And ARIs operator's daily VOCs inhalation EC was 11.24-1460.70 µg·m− 3.
