Contaminant and health monitoring of endangered Southern Resident killer whales
The Environmental Chemistry Program at NOAA’s Northwest Fisheries Science Center has been analyzing chemical tracers, including environmental pollutants, stable isotope ratios and fatty acids, in support of studies related to NOAA trust resources for more than 40 years. These analyses are conducted...

The Environmental Chemistry Program at NOAA’s Northwest Fisheries Science Center has been analyzing chemical tracers, including environmental pollutants, stable isotope ratios and fatty acids, in support of studies related to NOAA trust resources for more than 40 years. These analyses are conducted for a range of NOAA mission-critical projects such as: ensuring the safety of seafood in response to natural and anthropogenic disasters and providing scientific support on NOAA Natural Resource Damage Assessment litigation-sensitive studies on protected species such as Chinook salmon, marine mammals and sea turtles, and providing data that help describe the population age structure and foraging ecology (including marine distribution) of populations of ESA-listed marine mammals and salmonids. Southern Resident killer whales were listed as endangered in the United States and Canada as a result of the population declining. Since the early 1990s, US and Canadian studies have characterized toxic persistent organic pollutants (POPs) as a threat to this population.
