“…Its resistance to the toxic effects of common biocidal control agents such as chlorine has permitted the establishment of extensive populations of C. fluminea in industrial cooling water systems (Goss & Cain, 1977;Cherry et al, 1980;Harvey, 1981). The extent of the distribution of this organism and its resistance to the lethal effects of aquatic pollutants have prompted its use as a biomonitoring organism in freshwater environments similar to efforts with bivalves (Crassostrea gigas, Mya arenaria, Mytilus edulis, and Rangia cuneata) in brackish and marine water systems (Butler, 1969;Goldberg et al, 1978;Popham et al, 1980). Graney et al (1983) demonstrated that the Asiatic clam accumulates heavy metals such as cadmium (Cd), copper (Cu), and zinc (Zn).…”

The valve movement patterns of immobilized Asiatic clams (Corbiculafluminea) were monitored during exposure to constant concentrations of cadmium (0.0, 0.1, 0.2, 0.3, and 0.4 mg 1-') or zinc (0.0, 0.1, 0.3, 0.5, and 0.9 mg 1-l) for 24 h following a 24-h acclimation period. Data indicate that the duration of response was concentration dependent and toxicity related. Durations of periods with valves parted declined as the concentration of heavy metal increased. Behavior was consistent for both mean time to first closure following the initial exposure and mean time per valve parting episode over a 24-h exposure period. Mean time per valve parting episode during the 24-h exposure period ranged from = 600 minutes for control trials to 36 and 69 minutes for the highest concentrations of cadmium and zinc tested, respectively. There was no association between durations of periods with valves sealed and solutions of cadmium; however, lengthening durations of periods with valves sealed coincided with exposure of clams to progressively more concentrated zinc solutions. In addition, Asiatic clams demonstrated a greater rate of response (

“…The California mussel watch program (e.g., Ladd et al 1984), the U.S mussel watch (Goldberg et al 1978(Goldberg et al , 1983Farrington et al 1983), and the NOAA status and trends program (Boehm 1984) illustrate the use of both resident and caged transplant mussels to monitor bioaccumulation of toxic chemicals over space and time. Toxic chemical residues in mussels are excellent indicators of point source discharges as well as pollution gradients (Phillips 1976;Popham et al 1980;Phelps et al 1981). U.S. EPA (1982) described recommended protocols for caged mussel studies.…”

Through theoretical analyses and computer simulations sponsored by the Office of Naval Research, we are investigating hull coatings that can improve a vessel's performance by reducing the turbulence and associated noise and drag generated by the motion of the vessel through the water. Detoxification of Environmental Copper in the Common Mussel 9Laboratory environmental scientists are investigating the bivalve mollusc MI/II/HS edulis to understand its ability to metabolize increased quantities of potentially toxic metals found in polluted ecosystems. Modeling EMP Damage to Semiconductors 20Our computer models for predicting EMP damage to semiconductors have generated significant results that should help us design circuits with enhanced survivability.
