Abstract：Focused on thesurface soilssurroundingatypical electroplating industrial park ineastern Zhejiang，this study employed multiple methodologies toassess polution statusand healthrisks.Theresultsshowed thatinthesurface soil ofthestudyarea，exceptfor Hg，theaveragevalues ofother heavymetals exceeded thebackground values，showing enrichment，andsomeheavy metals hadlargecoeficientsofvariationandunevenspatialdistribution，whichwereseverely affcted byhumanactivities.Thecumulative index method indicates thattheoverallpolutionintheregion is light，but somepointshave heavy metalpolution.The potential ecologicalriskindex methodshows that theregionis heavilypollted by Cd，andattentionshouldbepaidtoelementssuchasHg，As，Cu，ndNi.Thehealthriskassessmentresultsshowthat adults face potentialnoncarcinogenicrisks，withoralintakebeingthe mainrouteandCrelementcontributingsignificantly; Thecarcinogenicriskis withinanacceptablerange，Cddoes notposeacarcinogenicisk，hileAs，Cr，andNihavecertain but controllable risks.
