The hypothesis that low-level contamination of a sandy loam soil with cadmium and lead at 0.01-9.0 and 3.0-54.0 ug g-1 soil respectively could induce a response in grasses as measured by the accumulation of soil Cd and Pb in sudan sorghum hay, was verified at the 0.08 and 0.05 levels respectively. Employing these data and the concentrations of Cd and Pb in blood, liver, kidney, select brain tissues and fetal tissues of pregnant goats as test animals consuming the hay over a 98 day feeding period, an assessment of the magnitude of these metals retained along select pathways of the agricultural food chain was developed.
