Toxic metals such as chromium and lead have been widely detected at thousands of priority sites in the United States. To mitigate the toxic effects on human and environmental health, it is essential to reduce the leachability and bioaccessibility of these metals. Although the concept of in situ immobilization has elicited great interest for decades, cost-effective in situ treatment technologies for reducing leachability and bioaccessibility of metals ...
