Genotoxic evaluation of polystyrene microplastic

Abstract

Pollution of the aquatic environment by microplastic could be having a massive impact on marine life. As far as the dimensions of the microplastics decrease, the negative effects are also increasing. In this study, the effects of 1 µm diameter polystyrene microplastics (PSMs) on Daphnia magna and Neocaridina davidi were investigated. The acute toxicity test was conducted on Daphnia magna. According to the test LC50 value was calculated as 808.97 μg/mL. According to genotoxic evaluation on Neocaridina davidi with single cell gel electrophoresis (Comet), tail length, tail intensity and tail moment were increased by PSMs compared to the control.
