Evaluation of Phosphate-Containing Amendments on Remediation Effect and Influential Factors in a Lead/Zinc Mining Tailings Contaminated Soil Using TCLP and Forms
用TCLP和形态法评估含磷物质修复铅锌矿污染土壤的效果及其影响因素

A pot experiment was conducted to evaluate the effects of phosphate-containing(P) amendments on the toxicity and bioavailability of Pb and Zn in a soil contaminated by mining tailings using toxicity characteristic leaching procedure(TCLP) and water soluble,exchangeable leaching procedures in order to find out the appropriate P application rates to reduce the soil TCLP extractable Pb to below the USA EPA's regulatory limit levels.The results showed that TCLP extractable Pb concentrations were significantly d...
