Title: EFFECTS OF TEMPERATURE AND SALINITY OF NAPHTHALENES UPTAKE IN THE TEMPERATURE CLAM, RANGIACUNEATA AND THE BOREAL CLAM, PROTOTHACASTAMINEA
Abstract: The temperate clam, Rangiacuneata, and the boreal clam, Protothacastaminea, were exposed. to a 25% WSF (water soluble fraction) of Southern Louisiana crude oil for three days under varying temperature and salinity regimes. The R. cuneata were exposed under temperature and salinity combinations of 15, 20, 25 and 30°C and 0, 10, 20 and 30 °/oo. Temperature-salinity combinations of 5, 10 and 15°C and 25, 30 and 35 °o were used in P_. staminea exposures. Clams were allowed to depurate for three days under these same temperature-salinity combinations. In three uptake experiments, two using I*, cuneata and one using P_. staminea, the greatest naphthalenes concentrations were measured in those clams exposed at the lowest temperatures. Statistical analysis confirmed that naphthalenes uptake in the different temperature-salinity groups in each experiment was significantly different. Temperature was shown to have the greatest effect on this difference. Salinity had a slight effect in only one of the R. cuneata uptake experiments. Tissue naphthalenes concentrations in P. staminea were less than those measured in R. cuneata after the same exposure period. Temperature and salinity had no effect on the release of naphthalenes in either R. cuneata or P. staminea.
