San Francisco Bay wildlife were tested for previously unmonitored contaminants using a non-targeted analysis that screens mainly for long-lived, fat-soluble, chlorine and bromine-rich chemicals. Bay mussel and harbor seal samples contained five contaminants not previously identified in Bay wildlife, and for which toxicity is largely unknown. Most of the Bay chemical contamination was from high priority contaminants that the RMP already monitors, or closely related compounds. Future non-targeted analysis could include techniques that examine water-soluble compounds.

A cutting edge analysis identifies low levels of five unmonitored compounds in wildlife of San Francisco Bay.

Ariel Rubissow-Okamoto’s article “Beyond the Blubber,” based on interviews with SFEI Senior Scientist Rebecca Sutton and NIST Investigator John Kucklick, provides the scientists’ perspective on a just-completed RMP study that searched Bay biota for unknown contaminants.
