摘要：Heavy metal concentrations in the industrially polluted soils (wheat field soil and onion field soil) amended with lake sediments were examined. Top soil (0-15cm) and sub soil (45-60cm) were sampled from the field irrigated with wastewater in the area of Hattar Industrial State, KP, Pakistan. Lake sediments were amended with the polluted soil samples and analysed for heavy metal’s concentrations. The concentration of zinc was found maximum in the wheat field soils while minimum in the onion field soils. The concentration of heavy metals such as Zn, Cu, Pb and Ni varied and found more in onion soil (OS) than wheat soils (WS). Extractable, water soluble and total forms of the heavy metals were detected in the amended polluted soils. It can be concluded that sediments can be suitable for detecting heavy metals in the polluted soils and help in reducing toxicity and eutrophication in lakes and dams.
