Cross-species extrapolation of prediction models for cadmium transfer from soil to corn grain. [PDF]

PLoS ONE, 2013
Cadmium (Cd) is a highly toxic heavy metal for both plants and animals. The presence of Cd in agricultural soils is of great concern regarding its transfer in the soil-plant system. This study investigated the transfer of Cd (exogenous salts) from a wide
