Assessment of toxicity of heavy metal contaminated soils by the toxicity characteristic leaching procedure.
Environ Geochem Health. 2006 Feb-Apr; 28(1-2):73-8.EG

Abstract

The concentrations of Cu, Zn, Pb and Cd in soils near a lead-zinc mine located in Shangyu, Zhejiang Province, China, were determined and their toxicity was assessed using the toxicity characteristic leaching procedure (TCLP) developed by the United States Environmental Protection Agency. The TCLP method is a currently recognized international method for evaluation of heavy metal pollution in soils. The available levels of Cu, Zn, Pb and Cd were 8.2-36, 23-143, 6.4-1367 and 0.41-2.2 mg kg(-1), respectively, while the international standards were 15, 25, 5 and 0.5 mg kg(-1), respectively. Soils around the mine were more polluted with Zn and Pb, followed by Cd and Cu. Moreover, the levels of heavy metals in the soils extracted by TCLP indicated that extraction fluid 2 was more effective than extraction fluid 1 in extracting the heavy metals from the polluted soils and there was a positive correlation between fluids 1 and 2. Available heavy metal contents determined by TCLP were correlated with soil total heavy metal contents.
