Cadmium contamination of agricultural soils and crops resulting from sphalerite weathering
The biogeochemistry and bioavailability of cadmium, released during sphalerite weathering in soils, were investigated under contrasting agricultural scenarios to assess health risks associated with sphalerite dust transport to productive soils from mining. Laboratory experiments (365 d) on temperate...

•Sphalerite containing cadmium presents a hazard when present in agricultural soils.•Sphalerite dissolution was slow (0.6–1.2% y−1) but constant in contrasting soils.•Cadmium was released during dissolution and was bioavailable to wheat and rice.•Wheat grains accumulated potentially harmful cadmium concentrations.•Flooded paddy (reducing) soils reduced cadmium bioavailability to rice.
Sphalerite dissolves steadily in oxic agricultural soils and can release highly bioavailable Cd, which may contaminate food crops destined for human consumption.</description><identifier>ISSN: 0269-7491</identifier><identifier>EISSN: 1873-6424</identifier><identifier>DOI: 10.1016/j.envpol.2013.09.001</identifier><identifier>PMID: 24077256</identifier><identifier>CODEN: ENVPAF</identifier><language>eng</language><publisher>Kidlington: Elsevier Ltd</publisher><subject>Agriculture ; Applied sciences ; Bioavailability ; Biological and medical sciences ; Biological and physicochemical properties of pollutants.
