摘要
针对在污水灌溉的土地上进行居住地或商业用地开发时可能存在的污染风险,在全面场地调查的基础上,以美国ASTM场地环境评价方法为基础,结合中国的人群特点和国内研究成果,对该场地污染土壤进行环境健康风险评价.结果表明:该场地部分点位两种重金属在土壤中的质量浓度超过中国现有的土壤环境标准,通过口腔摄入、皮肤接触和呼吸吸入污染物3种暴露途径所致的致癌风险未超过10-6,危害商未超过1,表明该场地对成人没有非致癌风险,污染物的致癌风险均在可接受范围之内,建议不用对该场地进行修复.
There may be health risk from the land that had been irrigated with sewage water and developed for residential and commercial land. Based on the full field investigation according to the site assessment procedure of American Society for Testing and Material(ASTM), human health risk was conducted to determine if the site need to be remediated. The results indicate that the site was mainly contaminated some kinds of heavy metal.Nickel and arsenic in soil samples were exceeded the national environmental standard. The carcinogenic risks and hazard quotients of these contaminants were not exceeded the accepted values, so remediation measures should not be taken for the site.
