Effects of subchronic simazine exposure on some biometric, biochemical, hematological and histopathological parameters of common carp (Cyprinus carpio L.).

OBJECTIVES: This study assessed the subchronic effects of a triazine compound, simazine, on common carp (Cyprinus carpio L.) though, via by means of biometric, biochemical, hematological, and histological examination.

DESIGN: One-year-old fish were exposed to simazine at four concentrations, 0.06, (reported concentration in Czech rivers), 4, 20, and 50 microg L-1 for 28 days and compared to carp in a non-treated control group.

RESULTS: Exposure of fish to simazine at 0.06 microg L-1 had no effect on measured parameters. However, exposure to simazine at the concentrations of 4, 20, 50 microg L-1 showed significant differences in biochemical, hematological, and histopathological profiles of fish compared to controls.

CONCLUSION: Our data suggest that simazine in the recorded environmental concentration 0.06 microg L-1 had no effect on common carp. Subchronic exposure to 4, 20, and 50 microg L-1 of simazine was associated with alterations in biochemical and hematological indices and in fish organ tissues.
