Report: Few eagles suffer serious lead exposure

A new Iowa State University reports says only a small fraction of bald eagles suffer from high levels of lead exposure.

The Des Moines Register reports that the ISU study was released Friday.

Julie Blanchong is an associate professor of natural resource ecology and management who led the study. She says while few bald eagles in the wild were found to have high levels of exposure, many samples taken from eagles showed small amounts of lead. The samples were taken from excrement gathered from 110 Iowa eagle nests.

Raptor rehabilitation centers in Iowa have found that most bald eagles that arrive sick or injured have been poisoned by lead from ammunition. They have called for ending the sale of shot and slugs made of lead.
