Flint, P.L., Petersen, M.R. 2023, Waterfowl lead exposure data in Alaska and Russia: U.S. Geological Survey data release,


This dataset identifies lead (Pb) concentration found in the blood of waterfowl sampled in western and northern Alaska and eastern Russia between 1993 and 2022. Data include age, sex, body measurement, capture location, presence or absence of lead shot on x-rays, and blood lead levels. Because the study took place over a number of years at the same study sites, many of the same birds were sampled in multiple years.

Birds were captured during spring, the breeding season, and the post-breeding season to determine changes and variability in lead contamination throughout the period birds were on land. These data have been used in a wide variety of scientific studies (see citation in the Cross-Reference Section of this metadata record) that are also useful for effective management decisions.
