Özet
Micro and nano-sized plastic particles are found almost everywhere, especially the aquatic system and because of their size, they can be in-gested as food by many organisms and these plas-tics which enter the food chain, raise a great con-cern. In this study, the effects of 50 nm diameter of polystyrene nanoplastics (PNPs) on Brachionus plicatilis and Daphnia magna were investigated. The acute toxicity tests were conducted on Bra-chionus plicatilis. According to the tests LC50 value was determined as 1.22 mg/mL (0.34-15.13, 95% confidence limits). Three parameters, tail length, tail intensity and tail moment were evaluat-ed to detect genotoxic effect of PNPs on Daphnia magna with single cell gel electrophoresis (Comet). According to the result PNPs were increased three parameters compared to the control. As a result, PNPs have negative effects on both aquatic organ-isms Brachionus plicatilis and Daphnia magna. © 2019 Parlar Scientific Publications. All rights reserved.
