Effects of cadmium and lead ingestion on tissue concentrations of cadmium, lead, copper, and zinc in mallard ducks

摘要: Abstract Juvenile mallard ( Anas platyrhynchos ) drakes were offered one of seven diets containing different concentrations cadmium (Cd) and/or lead (Pb) for 42 days. The contained the following (μg/g) supplemental metal(s): 0 (controls); 10 Cd; Pb; 100 Pb, 5 Cd plus and 50 Pb. At conclusion experiment, kidneys had average both Pb that three times greater than those in livers. In livers kidneys, approximately 15 at equal dietary two metals. ulnar bones similar to livers; did not accumulate bones. ingestion increased kidney copper (Cu) zinc (Zn); no such effect. results this study suggest elevated tissue (e.g. liver 18 μg/g dry weight, a concentration considered indicative toxicosis) waterfowl are due most instances factors other contaminated foods, as shot. Additionally, appear be generally superior monitoring when analytical detection limits pressed.
