Abstract: Using data of 6 pollution-free agricultural product bases in Guangxi Zhuang Autonomous Region, this paper analyzed content of heavy metals, including arsenic (As), mercury (Hg), lead (Pb), cadmium (Cd), and chromium (Cr) in soil. After Pb, Cd, Cr, Hg and As content in soil is determined, it evaluated the pollution of soil using single factor pollution index method and Nemerow synthetic pollution index method in combination with evaluation standard of heavy metals in soil and grading standard for soil pollution. Analysis results indicate that As, Hg, Pb, Cd, Cr content is different in pollution-free agricultural product bases, but all conform to related standards and there is no standard exceeding problem. It is concluded that the quality of soil in pollution-free agricultural product bases is excellent, not polluted and completely meet requirements of evaluation standards, and suitable for developing pollution-free agricultural products.
