Description Red swamp crayfish (Procambarus clarkii) were placed for a
period of 7 days in Bayou Trepagnier, a Louisiana waterway
which received petroleum-laden effluents from a manufacturing
complex several decades ago. However, coolant water from the
plant continued to be released into the bayou until 1995. Analyses
of sediments at the exposure site revealed heavy contamination by
lead, chromium, and copper, while concentrations of arsenic and
cadmium were very low. Significant bioaccumulation of lead was
observed in the hepatopancreas and gills of 7-day-exposed crayfish,
whereas chromium accumulated the most in the gills and
blood. Concentrations of copper in the crayfish did not change
during the course of the study, suggesting that this essential metal
constituent of the respiratory pigment is successfully regulated
even when crayfish are exposed to relatively high levels of copper
in the sediments. There was no metal accumulation in the abdominal
muscle of the crayfish. That damage to the hepatopancreas
occurred during the exposure is suggested by histopathological
studies which revealed swollen and vacuolated R cells and an
increase in the pH of the digestive juices. Blood glucose levels, as
well as ovarian and hepatopancreatic indices, were unchanged.
This study demonstrates that accumulation of nonessential metals
in crayfish tissues in a wetland environment contaminated by
mixed pollution (metals and hydrocarbons) reflects the concentrations
of metals in the sediment.
