农药企业搬迁土地挥发性有机物风险评价

Risk Assessment of Pesticides Enterprise Relocation Land Contaminated by VOCs

对常州某农药生产场地土壤中挥发性有机物（VOCs）污染状况以及健康风险和生态风险进行了调查评价。结果表明，该场地土壤中挥发性有机物污染以苯系物和卤代烃为主。苯系物质量浓度为0～56．6 mg/kg，卤代烃质量浓度为0～1．14 mg/kg。健康风险评价结果均在可接受范围内，而生态风险评价显示生产车间内的土壤 VOCs 生态风险较大，存在着对生物的危害。

The concentration and health and ecological risk assessment of volatile organic compounds （VOCs）in soil samples col-lected from the location of a factory that previously manufactured pesticides in Changzhou was evaluated.The results showed that BTEX and halohydrocarbon were the dominant contaminants with mass concentration ranges of 0 ~56.6 mg ＆#183; kg -1 and 0 ~1.14 mg＆#183;kg -1,respectively.The result of health risk assessment was in an acceptable value.However,the ecological risk assess-ment indicated a serious risk of the VOCs in the soil of the production workshop and there might be a biological hazard.
