Includes bibliographical references. "In 1993, a collaborative study was conducted by J.L. Metcalfe-Smith, Aquatic EcosystemProtection Branch, National Water Research Institute (NWRI), and E.T. Howell, Environmental Monitoring and Reporting Branch, Ontario Ministry of Environment and Energy (MOEE), to identify potential biomonitors for the Great Lakes Long-Term Sensing Sites Project (LTSSP). The objective of the LTSSP is to identify changes in environmental conditions in the nearshore areas of the Great Lakes by monitoring water and sediment. quality and biological indicators over time at index stations. In the past, caged mussels (Elliptic complanata) were used to monitor the bioavailability of contaminants at sites throughout the Great Lakes. Sampling was conducted at sites considered to represent exposure to contaminants under ambient (background) conditions, and at sites on the periphery of impacted locations where chronic low-level exposure to contaminants was expected. Results to date have been disappointing. Even afier fairly lengthy exposure periods, concentrations of metals in the soft tissues of mussels typically did not change from pre-exposure levels, and concentrations of organic contaminants were frequently non-detectable or extremely variable (e.g., Pope 1993). The main goal of the present study was to explore altemative biomonitors that may be more suitable candidates for the LTSSP"--Introd., p. 1.
