Environmental geochemical features of arsenic in soil in china

摘要

The background content of As in soil in china was calculated on the basis of 4093 soil samples collected from about 9.6 millions km~2 except Taiwan province. Some environmental geochemical features of As in soil were revealed by discussing the distributive differences of As in various regions, soil types, parent materials and binding species, studying on the correlation between As and coexisting elements, and by analyzing the migration of As from soil to atmosphere and crop according to test data.
