January 15, 2024 New paper by PhD student Stephanie Holbert: Polychlorinated biphenyl and polybrominated diphenyl ether profiles vary with feeding ecology and marine rearing distribution among 10 Chinook salmon (Oncorhynchus tshawytscha) stocks in the North Pacific Ocean provides compelling new insight into the drivers of contaminant accumulation in Chinook salmon, raises important questions about the consequences for their health, and explains a major pathway to the heavily POP-contaminated Resident killer whales that consume them.

 

August 10, 2023 New paper by PDF Dr. Antoine Simond: Declining concentrations of chlorinated paraffins in endangered St. Lawrence Estuary belugas (Delphinapterus leucas): Response to regulations or a change in diet? reveals that chlorinated paraffin concentrations have declined (1.3% per year, 28% over 2 decades), likely due in part to the implementation of regulations of this industrial chemical in 2012.

​

January 23, 2023 Paper by PhD student Bonnie Lo: Acute Toxicity of 6PPD-Quinone to Early Life Stage Juvenile Chinook (Oncorhynchus tshawytscha) and Coho (Oncorhynchus kisutch) shows that newly feeding coho exhibit a lethal concentration of 6PPD quinone that is 2.3 times lower than previously reported for 1+ year
coho salmon and that coho salmon are 3 orders of magnitude more sensitive to this tire associated chemical than Chinook.

August 30, 2022 New paper by PDF Dr. Antoine Simond: A Multi-Matrix Metabolomic Approach in Ringed Seals and Beluga Whales to Evaluate Contaminant and Climate-Related Stressors
