Brassica rapa subsp. chinensis; arsenic; cadmium; case studies; crops; environmental quality; equations; guidelines; heavy metals; lead; planting; polluted soils; pollution; soil resources; soil sampling; vegetables; China
Abstract:
... Regional guidelines for soil heavy metals, in conjunction with specific crops, are proposed to better assess soil environmental quality. In this study, large amounts of soils with different levels of Pb/Cd/As pollution were collected in Guangdong Province, China, to carry out a pot experiment, which was closer to the actual situation and properties of the heavy metal contaminated soils. Taking the ...

Abstract:
... Biochar (BC) derived from waste products is a cost-effective sorbent for remediation of metal-contaminated soils. We studied the kinetics and adsorption mechanisms for removal of metal ions, such as lead (Pb2+) and cadmium (Cd2+) with biochar. The adsorption capacities of BC for Pb2+ and Cd2+ increased after alkaline treatment. The highest sorption capacities were 175.53 and 68.08 mg g–1, for Pb a ...
