Protective effects of allozyme genotype during chemical exposure in the grass shrimp, Palaemonetes pugio.

The primary objective of this research was to determine if the genotype of the enzymes glucose phosphate isomerase (Gpi), phosphoglucomutase (Pgm), or mannose phosphate isomerase (Mpi) are factors affecting survival during acute endosulfan, fluoranthene, and chromium(VI) exposures. Palaemonetes pugio were exposed in the laboratory to 6.3 microg/L endosulfan, 100 mg/L chromium(VI), or 0.
