Description
Summary:Effects of carbofuran on the energy metabolism, Na super(+)/K super(+) ATPase activity, and reproductive parameters in Hyalella pleoacuta and Hyalella curvispina are investigated. It is observed that the diets are capable of sustaining the energy homeostasis of the amphipods, namely the formation of couples, the number of ovigerous females, and the mean number of eggs. The animals treated with carbofuran show lower levels of glycogen and total lipids than do the animals collected in the wild or are maintained only on the diet, independent of the length of time that they remain on the diet. The results reveal that carbofuran induces significant depression of glycogen, proteins, lipids, triglycerides, and Na super(+)/K super(+)ATPase, as well as a significant increase in lipoperoxidation. It is suggested that the reproductive parameters may provide sensitive criteria for assessing ecotoxicological effects.
