Based on years of research conducted by himself and colleagues, Dr. Beyer related sediment lead concentrations to injury to waterfowl in the Coeur d'Alene River Basin. He tied the contamination in the sediments directly to death and to sublethal measures of lead poisoning. The results became critical to the Department of the Interior's Coeur d'Alene River Basin Natural Resource Damage Assessment case, in which he was called as an expert witness.
Dr. Beyer has
demonstrated that estimating the exposure of waterfowl to lead and to
related metals is simpler than thought previously. When field data were
examined, it became clear that exposure to lead depends mainly on the
amount of sediment ingested and the sediment lead concentration.
In a series of papers he showed that for a risk assessment on
waterfowl to be credible, the assessor must consider sediment ingestion.
The researcher received a Scientific Achievement Award from the
U.S. Geological Survey for this work.
With coeditors Gary
Heinz and Amy Redmon-Norwood, Dr. Beyer edited a book entitled
"Environmental Contaminants in Wildlife: Interpreting Tissue
Concentrations," published in 1996.
