| | Title | Toxicity of lead-contaminated sediments to juvenile waterfowl, including estimation of |
| | sediment consumption by waterfowl |
| | Project Description | As the result of many decades of mining and smelting along the Coeur dAlene River in Idaho, |
| | waterfowl have been dying from lead poisoning since the early 1900s. This study is part of a |
| | Natural Resources Damage Assessment (NRDA) for the Department of Interior, designed to |
| | evaluate the effects of sediment ingestion on growth, survival, histopathology, behavior, and |
| | potential bioindicators of exposure in pertinent species of juvenile waterfowl, mallards (Anas |
| | platyrhynchos) and goslings (Branta canadensis). The objectives of this study are to (1) determine |
| | whether ingestion of Coeur dAlene River sediments is harmful to juvenile waterfowl (mallard |
| | ducklings and goslings), (2) estimate the consumption of sediment by waterfowl and several |
| | passerine species on the Coeur dAlene River and their exposure to lead, and (3) relate the above |
| | to field exposures of waterfowl in the Coeur dAlene area to better interpret field data at given |
| | residue levels for lead and needs for appropriate restoration. |
