“…The target species of VOCs consisted of 117 compounds, namely, photochemical assessment monitoring stations (PAMS) for ozone precursors (57 species), VOCs in the toxic organics (TOs)-15 standard (47 species), and aldehydes and ketones (13 species). The detailed analysis methodology was described by Jiang et al (2023) [27].…”

In recent years, commercial air transport has increased considerably. However, the compositions and source profiles of volatile organic compounds (VOCs) emitted from aircraft are still not clear. In this study, the characteristics of VOCs (including oxygenated VOCs (OVOCs)) emitted from airport sources were measured at Shenzhen Bao’an International Airport. The results showed that the compositions and proportions of VOC species showed significant differences as the aircraft operating state changed. OVOCs were the dominant species and accounted for 63.17%, 58.44%, and 51.60% of the total VOC mass concentration during the taxiing, approach, and take-off stages. Propionaldehyde and acetone were the main OVOCs, and dichloromethane and 1,2-dichloroethane were the main halohydrocarbons. Propane had the highest proportion among all alkanes, while toluene and benzene were the predominant aromatic hydrocarbons. Compared with the source profiles of VOCs from construction machinery, the proportions of halogenated hydrocarbons and alkanes emitted from aircraft were significantly higher, as were those of propionaldehyde and acetone. OVOCs were still the dominant VOC species in aircraft emissions, and their calculated ozone formation potential (OFP) was much higher than that of other VOC species at all stages of aircraft operations. Acetone, propionaldehyde, formaldehyde, acetaldehyde, and ethylene were the greatest contributors to ozone production. This study comprehensively measured the distribution characteristics of VOCs, and its results will aid in the construction of a source profile inventory of VOCs emitted from aircraft sources in real atmospheric environments.

“…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.
