Liver lead burden in hunter-killed ducks from the Coeur d'Alene River Valley of northern Idaho.
Liver lead burden was evaluated in ducks from an area in northern Idaho contaminated with mining waste and lead shot. Hunter-killed ducks with lead shot in their gizzard had a mean liver lead concentration of 15.18 +/- 2.51 micrograms/g wet-weight (N = 23) and ducks without lead shot had a mean liver lead concentration of 4.21 +/- 0.47 micrograms/g wet-weight (N = 85). The most hazardous source of lead for waterfowl in this area has been thought to be mining waste-contaminated soils and sediments. Three sediment samples had a mean concentration of 4,520 micrograms lead/g wet-weight.
