| 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. An internationally recognized four-step evaluation model of health risk assessment (HRA) was adapted to preliminarily assess the health risks caused by volatile organic compounds (VOCs) in urban-rural juncture belt area in Beijing. Results of HRA indicated that non-carcinogenic risk indexes of VOCs are below 1 and non-carcinogenic risk indexes of aromatic substances range from 10(-4)-10(-5), halohydrocarbons in the 10(-4)-10(-1). Volatile pollutants would not cause non-carcinogenic health hazard to exposed population. However, the cancer risk index exposed to carcinogenic benzene was 2.21 x 10(-5), which is higher than that suggested value of USEPA (1x10(-6)) and may cause potential harm to human health. The greatest health risk is in winter, followed by autumn, summer minimum" |
