Iron ore mining was the main cause of the increased concentrations of As and Cd, which represent a cancer risk for humans. We have measured the concentrations of toxic elements (Cd, Pb, As, and Hg) in 29 samples from agricultural soils in an iron ore mining area in the northern piedmont of Mount Wutai in Shanxi Province, China

Iron ore is the world’s third most produced commodity by volume - after crude oil and coal - and the second most traded commodity - only beaten by crude oil. The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators
