Abstrakt:	Reports that concentrations of Cd, Cu, Ni and Zn in corn leaf and Cd and Ni corn grain have decreased, while Cu and Zn in grain remained constant 13 years following cessation of biosolids applications. Higher Cd and Zn concentrations in corn grain from biosolids-amended fields; Leaves from amended fields with higher Cd, Ni and Zn concentrations than leaves from unamended fields; Overprediction of the uptake of Cd, Cu, Ni and Zn into corn at this Illinois site.
