Predictive Model for the Accumulation of Cadmium by Container-Grown Plants

摘要

Research into the dietary availability of Cd, a toxic heavy metal, called for prediction of Cd accumulation by edible crop species to be grown to maturity under greenhouse conditions. Examination of the literature revealed that Cd accumulation in plants grown under greenhouse and oxic conditions could be generally described, with high correlation, by the equation: log P = alpha + Beta log Cd sub DTPA, where P is plant Cd (micrometer/g Cd/g dry wt), Cd DTPA is the DTPA.
