Abstract

Microplastics are particles smaller than 5 mm that can enter to the environment through primary or secondary sources. These particles can be vector for various chemical compounds in the environment, such as pesticides and pollutants. The absorption of these particles into the body of organisms, especially aquatic organisms, causes changes in the activity of their enzymes, especially antioxidant enzymes. The aim of our study was to investigate the effect of polystyrene microplastic and chlorpyrifos pesticide alone and in combination on the superoxide dismutase (SOD) activity tissues of rainbow trout (Oncorhynchus mykiss). Fish were exposed to two concentrations of chlorpyrifos (2 μ g / L, 6 μ g / L), polystyrene microplastic (30 μ g / L, 300 μ g / L), and their combination. Then the superoxide dismutase activity was examined in the liver, kidney and muscle tissues of fish. Analysis of the results with significance level of Pvalue <0. 05 showed that in liver and kidney combination of microplastic and pesticide increased SOD activity and consequently microplastic decreased chlorpyrifos toxicity. In muscle enzyme activity increased at combination of 300 μ g/L microplastic and 30 μ gL-1 MPs pesticide and in combination of 30 μ g / L microplastic and 2 μ gL-1CPF pesticide enzyme activity was decreased. In general, it was concluded that microplastics in liver and kidney decrease the bioavailability of chlorpyrifos pesticide and in muscle increases the toxicity and bioavailability of pesticides.
