英文摘要Domestic solid fuels combustion produces a mass of fine particulate matter (PM2.5). PM2.5-bound organics, including polycyclic aromatic hydrocarbons (PAHs), oxygenated-PAHs (OPAH5), phthalate esters (PAEs) and hopanes, were quantified in indoor, outdoor and personal exposure samples collected in rural Guanzhong Basin, China. The average concentration of total quantified PAHs in personal exposure samples was 310 +/- 443 ng m(-3), 1.5 times of those of indoor (211 +/- 120 ng m(-3)) and outdoor (189 +/- 115 ng m(-3)). Similar observations were found for the OPAH5 and PAEs, i.e., much higher concentrations were seen in personal exposure samples. Hopanes average personal exposure concentration (13 +/- 9.7 ng m(-3)) was comparable to indoors (15 +/- 9.7 ng m(-3)) and outdoors (13 +/- 9.6 ng m(-3)). Among four common heating ways applied in Chinese dwelling, the highest exposure levels to PAHs, OPAHs and PAEs were found for indoor coal chunks stoves. Concentration under electric power was 1.2-4.5 folds lower than those with solid fuels in this study, proved to be the cleanest energy for the household heating. The exposures to PM2.5 on cell viabilities were also investigated. The largest reduction of 70% on cell viabilities was seen for indoor coal chunks stove housewives, indicating that the emissions from coal combustion had the greatest cytotoxic effects. The results evidenced that the heating ways in rural area could greatly impact on the housewife health in northwestern china. Advanced heating technology and protection should be conducted to reduce the personal exposures to PM2.5 from domestic solid fuel combustions. (C) 2019 Elsevier Ltd. All rights reserved.
