Abstract：Theenvironmental hazardsofatmosphericdepositionhazardous waste treatmententerprisesin Chinaaremainly manifestedintheaccumulationofheavy metals insoil.To studytheimpactofsuchenterprisesonthesuroundingsoil environment in eastern Henan，atypical hzardous waste treatment enterprise ineastern Henan was taken asanexample.Heavy metal elementssuchasAs，Cd，Cr，Cu，Pb，Hg，Ni，Znwereselected，andthemerowcomprehensiveindexmetod，lad accumulation index method，andpotential ecologicalhazard index method wereused tocarryout soilmonitoringandrisk assessmentinthesurroundingarea.Theresults showedthattherewasasignificantaccumulationofheavy metals inthesoil around the enterprise，and the order of contribution to ground accumulation pollution was Cd>Hg>Cu>Cr>Zn> （20 Pb>As>Ni. Cd and Hg reached a strong ecological hazard level.Research has shown that soil monitoring and pollution preventioninthe vicinityofatmospheric depositionhazardous waste treatmententerprises ineastern Henan shouldfocus on the soilenvironmentofadjacentareas，andstrengthentheinvestigationofsoilpolltionhazardsandself-monitoringofsoil in enterprises in response to the discovery of high pollution contributing heavy metals.
