上海某污染地块环境质量初步调查

Preliminary investigation on environmental quality of a contaminated plot in Shanghai

为了解某污染地块环境质量情况,对上海某地块进行环境质量初步调查,采集土壤样品进行重金属、多环芳烃类、邻苯二甲酸酯类、总石油烃及农药指标的测定。结果表明,土壤重金属指标均有不同程度的检出,其中镍的浓度超过相关标准;邻苯二甲酸酯类在部分样品中检出,浓度低于相关标准;总石油烃、多环芳烃类及农药指标均无检出。说明该地块需进一步调查评估污染物镍在场地内的分布范围,并根据结果评估土壤修复的可行性。

In order to understand the environmental quality of a contaminated plot,preliminary investigation on environmental quality was needed. Soil samples were collected for the analyzition of heavy metals,polycyclic aromatic hydrocarbons（ PAHs）,phthalate,total petroleum hydrocabons（ TPH）,and pesticide. The investigation showed heavy metals of the soil were detected in different degrees,and the detectable concentrations of Ni were higher than the related standards; phthalate was detected in some samples,the detectable concentrations were lower than the related standard; TPH,PAHs,and pesticide of the soil were not detected. The plot needs a further investigation to assess the distribution of Ni and to evaluate the feasibility of soil remediation.
