摘要
本研究调查了某化工园区及其邻近地区的水和土壤样品中55种目标挥发性有机化合物(VOCs)的赋存、分布和风险情况。水和土壤样品中55种VOCs的浓度分别为1.22~1 905.99μg/g和0~11.58 ng/g。土壤样品中以芳烃为主,水样中以卤代脂肪烃为主。在不同地点采集的水样中,VOCs浓度存在1~3个数量级的差异,园区内河水的平均浓度明显高于园区外河水。然而,风险商结果表明,VOCs对河水中相关的敏感水生生物的风险较低;园区土壤中VOCs的平均浓度略高于周边地区。
This study investigated the occurrence,distribution,and risk of 55 target volatile organic compounds(VOCs)in water and soil samples from a chemical park and its adjacent areas.The concentrations of 55 VOCs in water and soil samples ranged from 1.22~1905.99μg/g and 0~11.58 ng/g,respectively.Aromatic hydrocarbons were predominant in soil samples and halogenated aliphatic hydrocarbons were predominant in water samples.VOCs concentration in water samples collected at different sites was different by 1~3 orders of magnitude,and the average concentration of river water in the park was significantly higher than that of river water outside the park.However,risk quotient results suggest that VOCs pose a low risk to related,sensitive aquatic organisms in river water;the average concentration of VOCs in the soil in the park was slightly higher than that in the surrounding areas.
