Abstract
Industry emission is an important source of anthropogenic volatile organic compounds (VOCs) in China, which have caused elevated ground-level ozone (O3) and fine particulate matter (PM2.5) concentrations and potential adverse human health effects. This study investigated compositions, sources, and health risks of ambient VOCs in a residential area near an industrial park in Southeast China. The concentrations of total VOCs in spring and autumn were 16.7 +/- 10.2 ppbv and 14.7 +/- 8.35 ppbv, respectively. Alkanes and oxygenated VOCs (OVOCs) were the predominant components that contributed to the ozone formation potential (OFP), while the greatest contribution to secondary organic aerosol formation potential (SOAFP) was due to benzene, toluene, ethyl-benzene, and xylene (BTEX). Based on the positive matrix factorization model analysis, the relative contributions of individual VOC sources are as follows: industrial process (49.6% and 53.5% in spring and autumn, respec-tively), vehicle exhausts (26.9% and 33.2%), solvent usage (17.9% and 8.6%), and biogenic source (5.6% and 4.7%). The carcinogenic risk of benzene in autumn and those of 1,2-dibromoethane in both seasons exceeded the acceptable level of 1.00 x 10-6. The hazard index of the observed 21 toxic VOCs was less than 1, suggesting no non-carcinogenic risk at the monitoring site. This study provides valuable information on public health man-agement by taking effective measures to control benzene and halogenated hydrocarbon pollution from industry.
