Marine toxic contaminants
The Washington Department of Fish and Wildlife's Toxics Biological Observation System (TBiOS) team monitors the geographic extent and magnitude of toxic contaminants in marine and salmonid species in Puget Sound and Washington's Pacific coast. We evaluate and track complex patterns of pollution in these ecosystems using a number of indicator species within the food web, representing a wide range of habitat and movement patterns. Results from these studies help guide efforts to protect fish and shellfish health, ensure seafood safety, and promote ecosystem recovery.
Toxics Biological Observation System (TBiOS)
WDFW’S TBiOS team monitors the geographic extent and magnitude of toxic contaminants in fish and shellfish living in Puget Sound and Washington’s coast.
TBiOS monitors spatial and temporal trends of contaminant exposure in Puget Sound fish and shellfish and the effects of that exposure on the health of these resources.
Locations where TBiOS collects and evaluates levels of contaminants in various fish and shellfish species.
TBiOS monitors toxic contaminants in a number of indicator species within the food web, including Pacific herring, English sole, blue mussels, and Pacific salmon.
TBiOS monitors a wide range of toxic contaminants such as PCBs, PBDEs, DDTs, PAHs, inorganic metals and chemicals of emerging concern.
