污染与治理-119-工业场地重金属污染分布和形成关键因素的实用方法分析王珑(江苏佳蓝检验检测有限公司,江苏常州213000)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。关键词:重金属;污染空间分布;热点识别中图分类号:TS5文献标志码:ADOI:10.20025/j.cnki.CN10-1679.2023-02-41PracticalMethodAnalysisontheDistributionandKeyFactorsofHeavyMetalPollutioninIndustrialSitesWangLong(JiangsuJialanTestingCo.,Ltd.,Changzhou213000,China)Abstract:Chemicalplantsarethemainwayforheavymetalstobereleasedintothesoilandgroundwaterenvironment.Itisveryimportanttoidentifythefactorsaffectingheavymetalpollutionforbetterpreventionandmanagementofsoilpollution.Inthisstudy,heavymetalsinthesoilofalargeabandonedfactorywereinvestigatedcomprehensively.Acomprehensivemethodisproposedtoclassifyandquantifytheinfluencingfactorsofheavymetalpollutioninthefield.Inaddition,thequantitativerelationshipbetweenhydrogeologicalcharacteristics,pollutiontransmissionroutes,chemicalproductionprocessesandheavymetalpollutionhasbeenestablished.Theresultsofgeologicaldetectorsshowthatpotentialpollutionsourcesandsoilpermeabilityarethemaindrivingfactorsforthedistributionandaccumulationofheavymetals.Themaindrivingfactorsofdifferentheavymetalsarevariable,andtheinteractionofvariousfactorsalsoenhancesthepollutionofheavymetalsinsoil.Thispaperanalyzeshowtoextractthemixedeffectsofcomplexenvironmentalfactorstodeterminethekeyfactorsofpollutionformation,soastoguidefutureremediationstrategies.Keywords:heavymetals;spatialdis...
