Abstract: Taking different extraction solvents to study the bioavailability of various heavy metal elements and correlation between the available concentration and the total in vegetable soil.The result indicates that there was considerable diversity in the bioavailability of different heavy metal elements.The sequence was CdPbHgAsCr,the higher were Cd and Pb,the bioavailability coefficient of them were 43.36% and 6.57%.whereas the lowest was Cr,it was barely 0.15%.It was showed that available Cd and Pb in soil easily transported and accumulated by vegetable,moreover there was potential ecological risk.There was a very notable linear correlation between available Cd and total Cd in vegetable soil of tillage layer,its regression was Y=1.598 9X+0.046(n=108,R=0.866).Available Pb and total Pb exist in linear correlation,the coefficient correlation was 0.769.Available As and total As exist in linear correlation,the coefficient correlation was 0.671.There was no linear correlation between the available concentration and the total with Cr and Hg.Available Cd,Pb and As could be considered as the significant and impersonal indicators of enviornmental stress of heavy metal on soil.
