Abstract:

In order to evaluate heavy metals pollutions in the agricultural soil in southeast area of Zunyi, by using Sc as standardized factor, environment baselines models of heavy metals including Cd, Pb, Cr, Hg, As were obtained. At the same time, heavy metals pollutions in the agricultural soil in southeast area of Zunyi were evaluated by enrichment factor method. The results showed that 40% of soils were moderate polluted by Cd, Hg, As, 53% of soils were moderate polluted by Pb, 60% soils were moderate polluted by Cr. The rank of pollution was 1 level, and soils had been slight polluted by heavy metal pollutions in this area.
