某废弃化工厂土壤污染状况调查研究

Investigation and Research of Soil Pollution in Abandoned Chemical Plants

本文以曾生产氰化钠的某废弃化工厂遗留场地作为研究对象,对厂区内外土壤进行了采样、分析,重点测定了重金属、有机物和特征污染物,评价了该废弃场地土壤污染物状况。厂区内共设9个建设用地土壤监测点位,采集44个土壤样品,厂外共设3个农用地土壤监测点位,采集3个表层(0~20 cm)样品,结果表明:所有监测因子含量均低于《土壤环境质量建设用地土壤污染风险管控标准(试行)》(GB36600-2018)第一类用地风险筛选值。

This paper took the site of an abandoned chemical plant that produced sodium cyanide as the research object.Soil inside and outside the factory was collected for analysis.It evaluated the soil pollutant status of the abandoned site by measuring heavy metals,organic matter and characteristic pollutants.There was a total of 9 soil monitoring points for construction land in the plant area,and 44 soil samples are collected.A total of 3 agricultural land soil monitoring points were set up outside the factory,and 3 surface(0-20cm)samples are collected.The results showed that the contents of all monitoring factors were lower than the first category land risk screening value of the Soil Environmental Quality Construction Land Soil Pollution Risk Control Standard(Trial)(GB36600-2018).
