Sentinel organisms
Sentinel organisms, or indicator species that accumulate pollutants in their tissues from the surrounding environment or from food, are important biomonitoring devices (Phillips and Rainbow 1993; Kennish 1992). The Mussel Watch is one such use of a sentinel species (Phillips and Rainbow 1993; Kennish 1992). Filter feeders, such as bivalves (clams and mussels), tend to concentrate metals in their gills or other tissues. The widespread blue mussel (Mytilus edulis) accumulates metals in certain tissues over time. As a result, M. edulis became a species monitored in U.S. waters as well as internationally for changes in levels of pollution (Phillips and Rainbow 1993; Kennish 1992). Seaweeds, (e.g., Fucus spp.) accumulate metals. Older algal tissue can be compared to newer tissue in the same individual to determine the history of contaminants in an area (Phillips and Rainbow, 1993). Metals and organochlorines accumulate in finfish and territorial species or non-migratory species such as pike, largemouth bass, can be used for an accurate indication of mercury and organochlorine pollution in a water body (Phillips and Rainbow, 1993).
