Summary

This data release contains analytical results of organohalogenated compounds and mercury in lamprey and sediment that were collected from rivers in Oregon and along the Pacific northwest coast from 2017 to 2021. In 2017, 20 lamprey were collected off the Washington and Oregon coasts by the National Oceanic and Atmospheric Administration. These ocean-caught juvenile lamprey were parasitizing targeted fish and were bycatch. In 2019, larval lamprey were collected by the Confederated Tribes of Warm Springs of Oregon from 8 sites on the Warm Springs Reservation. Larval lamprey were collected by electroshocking depositional sediment areas. Collocated depositional sediment samples also were collected along with the larval lamprey. In 2021, [...]

Purpose

Contaminants in multiple life stages of the Pacific lamprey were analyzed to evaluate 1) the compounds and concentrations that are detected in tissues, 2) possible contaminant sources, and 3) concentrations in adult lamprey that may be consumed by humans. This data release contains the supporting information for the interpretative publication.
