Residues of organochlorine chemicals and concentrations of heavy metals in ciconiforme eggs in relation to diet and habitat
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 Doñana National Park, (Spain) during the nesting season 1983 and 1984. The species analyzed were the Spanish frog...
