- ... PURPOSE: Cd-contaminated soil is a common environmental problem. Stabilization is an effective way of in situ remediation for Cd contamination in soils, but there is a lack of information about the influences of the amendments on soil ecosystems and Cd uptake by crops, especially under field conditions. In this study, surface-modified nano-silica (SMNS) was used to stabilize a Cd-contaminated soil ...

- ... PURPOSE: Tannery waste–contaminated soil has a high amount of several toxic chemicals and heavy metals including chromium (Cr), which makes it unsuitable for agriculture practices. Majority of studies have reported the use of biochar (BC) as an amendment to restore contaminated soil. The efficiency of BC to immobilize Cr depends on its pretreatment and feedstock. This study aimed to investigate th ...
