Abstract:In order to investigate the situation of heavy metal contamination and pesticide residue in tobacco-growing soils in Liaoning province, the contents of As, Hg, Pb, Cd, Cr, Cu, Ni, HCH and DDT were measured in soils from 10 counties ( cities ) in Liaoning, and evaluated. The results showed that whether the whole tobacco-growing area or the each county(city),the contents of Cr,Ni ,Cu,As all reached the first standard of national soil environmental quality, Hg content all reached the second standard of national soil environmental quality;the contents of Cd ,Pb reached the second,first standard of national soil environmental quality respectively, for the whole tobacco-growing area, only which in individual area reached the first, second standard of national soil environmental quality respectively. Whether the whole tobacco-growing area or the each county ( city ) , the residues of HCH and DDT all reached the first standard of national soil environmental quality. The single factor pollution indexes of As, Hg,Pb,Cd,Cr,Cu,Ni,HCH and DDT were all less than 1,the Nemerow comprehensive pollution indexes of heavy metals, pesticide were 0. 60, 0. 042, respectively. These results suggested that the tobacco-growing soils in Liaoning were clean, and the soils were suitable for the production of nuisanceless agricultural products.
