Residues of organochlorine pollutants and heavy metals were determined in 50 aquatic organisms of five species, 31 eggs of four species of wading birds, water, and sediment collected at Donana National Park, (Spain) during the nesting season 1983 and 1984. Hg, Cd, Pb, Cu, and Zn were detected in all samples. The levels of contaminants investigated are generally below the levels known to cause direct effects on survival or reproduction. Biomagnification of the organochlorine pollutants and Hg is clearly illustrated; there is no evidence of accumulation of Cd, Pb, Cu, and Zn along a food chain.
