Cattle allowed to graze pastures variously treated with anaerobically digested sludge (ADS) for up to 8 years, contained higher concentrations of heavy metals and organic compounds in some tissues than did cattle not exposed to ADS. Chemical analyses were made on heart, diaphragm, liver, kidney, brain, and bone to determine the amount of Zn, Cu, Cd, Cr, Ni, Pb, Fe, and Hg. Determinations for organic compounds (polychlorinated-biphenyls, dieldrin, and heptachlor/epoxide) were made on visceral… CONTINUE READING
