Název v původním jazyce

Effects of pesticides on catfish (Silurus glanis) embryos

Popis výsledku v původním jazyce

Pesticides and many other types of contaminants have been constantly entering the aquatic environment. Pesticides, which are commonly used in agriculture, can have a negative impact on nontarget species as well as human health. In the few past decades, water pollution caused by pesticides has become a commonly discussed issue. Residues of pesticides enter water environment, where they persist and have bioaccumulation potential. The aim of this research was to compare the effects of herbicide MCPA (4-chloro-2-methylphenoxyacetic acid), fungicide prochloraz and herbicide metazachlor on catfish (Silurus glanis) embryos in 96 hours long acute toxicity test with the five different tested concentrations. In the study, statistically significant changes were observed only at high concentrations that do not occur in nature. The results of the study show that the substances had a negative effect on fish development at some tested concentration. However, this screening study must be followed by studies of sub chronic and chronic toxicity with focus on lower tested concentrations in order to reveal a potential negative impact of long-term exposure to non-target species.
