Evaluation Heavy Metals Pollution in Topsoil around Dalate Power Plant in Erdos

Abstract:

The concentrations of heavy metals(Cd, Cr, Zn, Cu and Pb) in topsoil and dust-fall around Dalate Power Plant were analyzed for assessing heavy metals pollution risk in Erdos, China. Topsoil and plants were collected in open area. The results show topsoil windward of Dalate Plant is clean. Topsoil leeward is polluted by heavy metals, heavy metals concentrations increase till 2500m, then decrease to background level. Dust-fall is an important heavy-metals source leeward.CF and PN indicate there are slight Cr and Cd pollution in 2500m topsoil. The rest topsoil is suspected contaminated by heavy metals. Ex indicate Cr and Cd pollution can be monitored and restored by Didymodon vinealis and Bryum argenteum Hedw., Zn and Cu pollution can be monitored and restores by Populus sinonii and Artemisia ordosica in the area.
