The background value of heavy metals in agricultural soils is low, as is exposed in the investingation of soil heavy metals, Mercury, Arsenic, Chrome, Cadmium and Lead and their pollution. The status of heavy metal pollution is that the content of Mercury, Arsenic, Cadmium and Lead in the soil is 1~4 times higher than the background value, respectively (except Chrome). Mercury and Arsenic are the major contaminants in the soil. In terms of content of heavy metals (except for Mercury) paddy soils > lateritic red earth, according to soils type; and paddy field > vegetables soil > orchard soil, according to the ways of land utilization; and agricultural soil in the Jiulong River basin>others(except for Chrome), according to the basin. The pollutants come mainly from agricultural sources rather thanindustrial ones.
