Over the past several decades, industrial development throughout the world has resultant in the contamination of soil with heavy metals. Especially, mining and metallurgical industrial areas which when dumped necessarily result in soil contamination. These metal contaminated soil occurrence a risk to humans, animals and environmental. There are many physical, chemical and biological methods to remediate the organic and inorganic pollutants in soil. These among, conventional physicochemical methods have been frequently applied to remediate contaminated soil, but its expensive and can be destructive to soil function. The treat of chemical amendment in a beneficial way may lead to the application of an environment-friendly soil remediation technology. Therefore, objective of this research was to evaluate the effectiveness of chemical amendments and soil layer engineering methods on the mobility of Cd in contaminated paddy soil near to a mining site. Field experiments were conducted in order to assess the effects of chemical amendments and soil layer engineering methods on the Cd stabilization in paddy fields near the abandoned metal mine where paddy soil was contaminated with Cd. Soil samples were taken with different time interval and Cd concentration (0.1 N HCl extraction) in soil were monitored accordingly. After harvest, Cd concentration in ri ... 전체 초록 보기
