The separate and interactive pollution effects of cadmium and mercury on the electrophoretically detected allozyme frequencies of the phosphoglucomutase isozyme were tested in Palaemon elegans. Our results indicate differential survivorship of allozyme genotypes specific for each metal and for their interaction. These results reflect the adaptive nature of the allozyme genotypes tested in this shrimp and seem to be inconsistent with the neutral theory of allozyme polymorphisms. Furthermore, these findings suggest that the interactive contamination of cadmium and mercury acts as a specific contaminant. Therefore, differential tolerance of allozyme genotypes to metals can be used as a detector of heavy metal contamination in the sea not only for individual pollutants, but also for many pollutants and their interactive effects.
