摘要

According to the National Standard of the People''s Republic of China (GB/T18407.1-2001), environmental quality assessment of heavy metal in soil of pollution-free vegetable produced in Hebei Plain Area was carried out. The results by the single-index model indicated that the areas of the Grade I of pollution-free vegetable soil with As, Hg, Pb, Cd, Cr were all above 94%, others were Grade II and upward except Cd with 0.34% area of Grade III. The result by the multi-index models showed that the areas of the Grade I, II, III were 93.02%, 6.62% and 0.31% respectively. To sum up, environmental quality of heavy metal in soil of Hebei Plain Areas is benign, and the heal mental excessive rate in soil (GB/T18407.1-2001) is relatively low, which lays a solid foundation for the wide future developments of pollution-free vegetable and green vegetable planting bases.
