Effects of Test Spills of Chemically Dispersed and Nondispersed Oil on the Activity of Aspartate Aminotransferase and Glucose-6-Phosphate Dehydrogenase in Two Intertidal Bivalves, and

Source

In 1981, two test oil spills were made in Maine. One spill was 975 L (250 gal) of Murban crude oil; the other was 975 L of Murban crude oil premixed with 97 L (25 gal) of Corexit® 9527. The uptake of the oil and its effects on enzymatic activity in two species of common intertidal bivalve mollusks, Mya arenaria and Mytilus edulis, were studied. Data were obtained on uptake and depuration of the oil for each species; data were also obtained on the activity of glucose-6-phosphate dehydrogenase and aspartate aminotransferase for each species. Data were collected both before and after each of the spills. Much less oil was taken up by the populations of animals exposed to chemically dispersed oil than by those exposed to nondispersed oil. Rates of depuration were the same for each species; they were also the same regardless of oil exposure. Significant long-term effects on enzyme activity were detected only in those animals exposed to nondispersed oil.
