Scott, G., D. Middaugh, AND T. Sammons. INTERACTIONS OF CHLORINE-PRODUCED OXIDANTS (CPO) AND SALINITY IN AFFECTING LETHAL AND SUBLETHAL EFFECTS IN THE EASTERN OR AMERICAN OYSTER, 'CRASSOSTREA VIRGINICA' (GMELIN), INFECTED WITH THE PROTISTAN PARASITE, 'PERKINSUS MARINUS'. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/D-85/196 (NTIS PB85243129).
Description:
Exposure of oysters, infected with the protistan parasite, Perkinsus marinus, to high salinity and high salinity, chlorine-produced oxidants (CPO) conditions was quite toxic. The combination of high salinity and CPO exposure generally increased toxicity above levels measured in high salinity controls and was generally correlated with parasitism by the protistan parasite, P. marinus. Low salinity and the combination of low salinity and CPO exposure resulted in a significant reduction in P. marinus related oyster mortalities. Low salinity, CPO exposure reduced oyster mortalities from P. marinus infections by as much as 56%.
