PCB Exposure and Disease Susceptibility

Active
By Marrowstone Marine Field Station (MMFS) November 18, 2020

Pacific herring

Researchers at that MMFS are experimentally determining the impacts of high PCB body burdens on the immunocompetency and disease susceptibility of Pacific herring.

High levels of Polychlorinated biphenyls (PCB’s) occur in the Puget Sound food web, with the highest concentrations occurring in top order charismatic species such as orcas.  Unfortunately, the biological effects of high PCB body burdens are poorly investigated in most marine species.  We are experimentally determining the impacts of high PCB body burdens on the immunocompetency and disease susceptibility of Pacific herring.

Contaminants in Puget Sound Forage Fishes and Impacts to the Marine Food Web

Toxic chemical pollutants have been released into Puget Sound for decades by human activities. There’s a wide range of contaminants, from persistent compounds like polychlorinated biphenyls (PCBs) and flame retardants to contaminants of emerging concern. Aquatic species can be exposed to and accumulate contaminants, causing disease or disruption of biological processes like growth or reproduction...
