Microplastic Particles’ Effects on Aquatic Organisms and Their Role as Transporters of Organic Pollutants

Microplastic (MP) contamination is considered a growing problem in terms of its production and observed impacts on aquatic organisms. In this study, we investigated the adverse effects that could occur from pure polyethylene (PE) MPs PE contaminated with phenanthrene (Phe) chlorpyrifos (CPF) D. magna podocopid ostracods. The organisms were exposed to different sizes (1–5, 27–32, 45–53, 212–250 μm) concentrations (0, 16, 160, 1600, 16,000 particles/mL) using static dynamic model exposition. results indicate both daphnia ostracods can ingest MPs, effect most cases directly proportional concentration MPs. Exposure MP did not affect However, at 21 days, they induced significant decrease (p < 0.05) neonatal compared control. + CPF negatively affected crustaceans when concentration, exposure time increased size was decreased. Neonatal sensitive juveniles adults. Phe caused mortality increasing size, while ostracods, decreasing particle size. would depend time, organisms, It also shown toxicity increases these particles are associated contaminant, which role as transporter organic contaminants.
