Abstract
    In a study of the toxicity of mercury, silver, copper, nickel, and zinc to larvae of the American oyster Crassostrea virginica and hard clam Mercenaria mercenaria, the concns at which 5% (LC5), 50% (LC5), and 95% (LC5) of the larvae died were determined, as well as growth at the LC 95 of the larvae died were determined, as well as growth at the LC5 and LC50 values. The order of toxicity for oyster larvae was Hg>Ag>Cu>Ni, and for clam larvae Hg>Cu>Ag>Zn>Ni. Growth of larvae of both spp, with the exception of clam larvae in nickel-treated water, was not reduced at the LC 5 values, but was markedly reduced at the LC5 values.
