摘要
为建立全国化工园区监测网,化工园区等重点污染源周边地下水环境状况亟须调查。针对河南省某化工产业园,在初步调查的基础上,对该化工园区浅层地下水中重金属、无机物及挥发性有机物等85个检测因子进行取样分析。以《地下水质量标准》(GB/T 14848—2017)中的三类限值为标准,运用单指标评价法对调查范围内浅层地下水环境质量进行污染评价。结果表明:该化工产业园超标因子为常规指标,部分因子超标是企业和原生地质环境共同作用引起;部分特征污染物检出,但均未超标;园区内企业生产对园区地下水未有明显污染,但存在潜在风险,建议加强监测和监管。
In order to establish the national chemical park monitoring network,it is urgent to investigate the groundwater environment around the chemical park and other key pollution sources.Based on the preliminary investigation,85 factors of heavy metals,inorganic substances and volatile organic compounds in shallow groundwater of a chemical industry park in Henan Province were sampled and analyzed.Based on the three limits in the Groundwater Quality Standard(GB/T 14848—2017),a single index evaluation method was used to evaluate the environmental quality of shallow groundwater within the scope of investigation.The results show that the overstandard factors of the chemical industry park are conventional indicators,and some factors are caused by the joint action of enterprises and the original geological environment.Some characteristic pollutants were detected,but none exceeded the standard.There is no obvious pollution to groundwater in the park,but there is potential risk,so it is recommended to strengthen monitoring and supervision.
