摘　　要：对南方典型玻璃钢生产场地土壤开展了污染调查与评价。共钻孔31个,采集样品137个,分析无机指标和有机指标63项,包括重金属指标8项、石油烃(C10~C40)等挥发性有机物(VOCs)27项、半挥发性有机物(SVOCs)25项(含邻苯二甲酸酯6项)以及多氯联苯3项。结果表明,在土壤样品中检出了7种不同程度的重金属,即砷、镉、铜、铅、镍、汞和总铬,质量分数在0.0300~152.0000 mg/kg;还检出了10种有机污染物,包括石油烃(C10~C40)、2-氯酚、邻苯二甲酸二(2-二乙基己基)酯、苯并(a)芘、氯仿、乙苯、间二甲苯、邻二甲苯、苯乙烯和邻苯二甲酸二正丁酯,检出量为0~50.4000 mg/kg。所有指标检出量均低于风险筛选值。因此,该地块土壤污染程度较低,造成的健康风险在可接受范围内。The soil pollution of typical glass fiber reinforced plastics production sites in South China is investigated and evaluated.A total of 31 boreholes are drilled,137 samples are collected,and 63 inorganic and organic indexes are analyzed,including 8 heavy metal indexes,27 volatile organic compounds(VOCs)such as petroleum hydrocarbons(C10~C40),25 semi volatile organic compounds(SVOCs)(including 6 phthalates)and 3 polychlorinated biphenyls.The results show that 7 kinds of heavy metals with different degrees are detected in soil samples,namely arsenic,cadmium,copper,lead,nickel,mercury and total chromium,with a mass fraction of 0.0300~152.000 mg/kg;10 kinds of organic pollutants are also detected,including petroleum hydrocarbons(C10~C40),2-chlorophenol,di(2-diethylhexyl)phthalate,Benzo(a)pyrene,chloroform,ethylbenzene,m-xylene,o-xylene,styrene and di-n-butyl phthalate,the detection amount is 0~50.4000 mg/kg.The detected quality scores of all indicators are lower than the risk screening value.Therefore,the soil pollution degree of this plot is low,and the health risk is acceptable.
