In this study,several soil Profiles near steel factories,representing different land uses forest,upland and paddy field,were selected.Soils were sampled by vertical high-resolution layers.In each profile,soils were sectioned in 2 cm intervals in the first 40cm,then 5cm intervals in next 40 cm,and 10 cm intervals in the last 20cm of profile.Additional dust samples near steel factories were also collected.The concentration of Cu,Zn,Pb,Cd and Ti was determined.Pb isotope ratios of some soil and dust depositions were measured by thermal ionization mass spectrometry.More detailed and precise information about the vertical distribution of trace metals in soil profiles was obtained by intensive layering sampling method than that by routine pedological horizon sampling.The distribution patterns of trace metals in the forest soils and arable soils were different,as in the forest soils,trace metals moved very slowly downward,reflected by the sharp declination of their concentration,while in the upland and paddy field,trace metals were distributed evenly in the agriculturally mixed layers and below the cultivated layer a new migration took place gain.The Pb isotope ratios in soils and dust deposition also suggested that the enriched trace metals in surface horizons were mainly from industrial emission and,also that anthropogenic Pb had moved to bottomsoils in paddy soil.Pb isotope signature is more accurate to reflect the migration of Pb in soils than simply by its apparent concentration.
