Projects Related to the Emerging Contaminants

Contaminants of Emerging Concern Strategy

More than 100,000 chemicals have been registered or approved for commercial use in the US. For many of these chemicals, major information gaps limit evaluations of their potential risks, and environmental monitoring of these chemicals has not been required by regulatory agencies. Nevertheless, researchers and government agencies have begun to collect occurrence, fate, and toxicity data for a number of these chemicals.

A Broad Scan of Bay Contaminants: Non-targeted Analysis of Bay Wildlife

A cutting edge analysis identifies low levels of five unmonitored compounds in wildlife of San Francisco Bay. Bay mussel and harbor seal samples were tested for previously unmonitored contaminants using a non-targeted analysis that screens mainly for long-lived, fat-soluble, chlorine and bromine-rich chemicals. The 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.
