Cadmium contamination of agricultural soils and crops

23 The biogeochemistry and bioavailability of cadmium, released during sphalerite 24 weathering in soils, were investigated under contrasting agricultural scenarios to assess 25 health risks associated with sphalerite dust transport to productive soils from mining. 26

Fertilizer usage and cadmium in soils, crops and food

Phosphate fertilizers were first implicated by Schroeder and Balassa in 1963 for increasing the Cd concentration in cultivated soils and crops. This suggestion has become a part of the accepted paradigm on soil toxicity. Consequently, stringent fertilizer control programs to monitor Cd have been launched. Attempts to link Cd toxicity and fertilizers to chronic diseases are common. A re-assessme...

Fertilizer Impacts on Soils and Crops of Sub-saharan Africa

Editors The MSU International Development Paper series is designed to further the comparative analysis of international development activities in Africa, Latin America, Asia, and the Near East. The papers report research findings on historical, as well as contemporary, international development problems. The series includes papers on a wide range of topics, such as alternative rural development...

Cadmium Levels in Soils and Crops in the United States

The concentrations of cadmium in agricultural soils depend upon the amounts present in the parent rocks from which the soils form, the amounts added in the form of fertilizers and soil amendments, the amounts deposited onto soils from the atmosphere, and the amounts removed by harvested crops and by leaching. On average, sedimentary rocks contain greater concentrations of Cd than either igneous...
