摘要
化工厂是重金属释放到土壤、地下水环境中的主要途径之一。识别影响重金属污染的因素对于更好地预防和管理土壤污染至关重要。本研究对一个大型废弃工厂土壤中的重金属进行了全面调查,提出了一种综合方法来分类和量化现场重金属污染的影响因素。此外,本研究还建立了水文地质特征、污染传播途径、化工生产过程和重金属污染之间的定量关系。地质探测器探测结果表明,潜在污染源和土壤渗透性是重金属分布和积累的主要驱动因素。不同重金属的主要驱动因素是可变的,各因素之间的相互作用也增强了土壤重金属的污染。本文分析说明了如何提取复杂环境因素的混杂影响,以确定污染形成的关键因素,从而指导未来的补救策略。
Chemical plants are the main way for heavy metals to be released into the soil and groundwater environment.It is very important to identify the factors affecting heavy metal pollution for better prevention and management of soil pollution.In this study,heavy metals in the soil of a large abandoned factory were investigated comprehensively.A comprehensive method is proposed to classify and quantify the influencing factors of heavy metal pollution in the field.In addition,the quantitative relationship between hydrogeological characteristics,pollution transmission routes,chemical production processes and heavy metal pollution has been established.The results of geological detectors show that potential pollution sources and soil permeability are the main driving factors for the distribution and accumulation of heavy metals.The main driving factors of different heavy metals are variable,and the interaction of various factors also enhances the pollution of heavy metals in soil.This paper analyzes how to extract the mixed effects of complex environmental factors to determine the key factors of pollution formation,so as to guide future remediation strategies.
