- Abstract
Taking the surrounding region Second Ring of Eastern Xi'an as the study object, the lead forms and the atmospheric concentration of TSP and PM10 were analyzed by using Tessier's sequential extrac-tion method and Atomic Absorption Spectrophotometry, correlation analysis, and the biologic effective-ness. The results showed that the pollution of TSP and PM10 at the observation points were seriously. Pb mainly existed in the carbonate bound form in TSP,it was concerned with dust;Pb mainly existed in the exchangeable speciation and residual speciation in PM10, it was concerned with the industrial production and human life. The biological availability coefficients showed that Pb could threaten potentially human health. The biological effectiveness in TSP was greater than in PM10, and the coefficients in the non-heat-ing period was greater than in the heating period. The element of Pb in PMi0were richer than in TSP, the element of Pb in TSP and PM10, it's possible to follow the same migration and transformation, and they had the same source.
