Changes in oxygen consumption and biochemical composition of the marine fouling dreissinid bivalve Mytilopsis sallei (Recluz) exposed to mercury.

Abstract

The effect mercury (Hg) on tolerance, oxygen consumption, and body biochemical composition of a marine dreissinid bivalve Mytilopsis sallei was investigated. The 96-hr LC50 of Hg for M. sallei was found to be 0.2571 mg/liter and the safe concentration was 2.6 micrograms/liter. Exposure of M. sallei to Hg resulted in a significant decrease in oxygen… (More)
