AbstractSystematicallyxploredteverticaldistributionlawandharactersticsofhmcalboundedsofheavmetalsschasd，Hg， As，and Pb inthesoil around Xingyang City，Zhengzhou.Theresults showed thatCd wassignificantlyenrichedinthesurface soil （0- 20cm ），with concentrations2-3 timeshigher than that in the deep soil （ 150-200cm ） due to the influence of industrial and agricultural activities.Bounded form analysis showed that the proportion of exchangeable form of Cd was as high as 18% ，with outstandingbioavailabilityand significant environmental risks.And Pb mainly existed in the bounded form of iron and manganese oxides（ 40% ），which iseasilyactivated and migrated under acidic conditions.
