摘要： 在重庆市各农产品的主产地，采集了柑桔果实、水稻、苋菜、莴笋、大葱、四季豆、辣椒、甘蓝及其土壤样品共314个，测定了样品中重金属铅、镉、汞、砷的含量。方差分析和聚类分析结果表明，八种农产品中柑桔果肉、甘蓝、辣椒、四季豆对土壤中铅、镉、汞、砷的吸收富集能力很小。在铅、镉、汞、砷含量相对较高的土壤宜选择种植这四种作物。

Abstract: Collection 314 samples of citrus fruits, rice, three-colored amaranth, asparagus lettuce, green Chinese onion, French bean, hot pepper, wild cabbage and the soil, test the content of heavy metal Pb, Cd, Hg and As in these samples. By direction difference analysis and clustering analysis, the accumulating ability of citrus pulp, wild cabbage, hot pepper, French bean is very small in the 8 kinds of agricultural products. It is fit to plant citrus pulp, wild cabbage, hot pepper, French bean in the soil where there is higher content of Pb, Cd, Hg and As.
