| Abstract: | "A method for determining volatile organic compounds (VOCs) by cryogenic dynamic adsorption in solid adsorbent tubes, subsequent thermal desorption with cryofocusing in a cold trap and analysis by gas chromatography and mass spectrometry was adapted for continuous ambient air monitoring. VOCs pollution characteristics and health risk assessment (HRA)were researched in detail. Moreover, the sources apportionment was reliably analyzed by positive matrix factorization (PMF) model. The results showed that the average concentration of VOCs was 332.34 mug.m(-3) per day, the concentrations of aromatic hydrocarbon and halo hydrocarbon were remarkably high compared to the other VOCs. Particularly, the PMF analysis results revealed that solvent/paint use emission, biomass or coal combustion and motor vehicle exhaust emissions were the main pollutants emission sources. Additionally, the cancer risk index of all carcinogenic substances was higher than the suggested value of USEPA(1x10(-6)), which could cause potential harm to human health" |
