Abstract

Earthworms and soils were collected from subsidence area of Xieyi coal mine and were analyzed for Zn, Pb, Cd, Cr and Cu by ICP-OES. The Zn and Pb could be accumulated much higher in earthworm with bioconcentration factors of Zn (1.39) and Pb (2.17) above 1. In addition, the Cd concentrations in earthworm related with that concentrations in soil (r = 0.95, p < 0.05) and were best described by a linear equation (y = ax + b), which indicating that earthworm could be used as a biological indicator in Cd contaminated soil in the subsidence area.
