Sažetak
Pollution of aquatic ecosystems by plastics with a particle size <5 mm, or microplastics, is becoming a global problem. This presents a threat to aquatic organisms but also to other organisms due to the possibility of transmission through trophic levels. The toxic effects of these particles have been partially proven, but a large part is still unexplored. Microalgae, as primary producers, are at the bottom of the trophic chain in the aquatic ecosystem. They are often used as tested organisms in various ecotoxicological studies. In this study, the toxicity of microplastics: polyethylene (PE), polypropylene (PP), polystyrene (PS), poly (vinyl chloride) (PVC) and poly (ethylene terephthalate) (PET), has been observed on freshwater microalgae Chlorella sp. and Scenedesmus sp. The influence of three particles sizes - 100-300, 300-500 and 500-700 μm at three different concentrations of microplastics, 50, 500 and 1000 mg/L during 72 hours was investigated. According to the results, the toxic effect of microplastics on microalgae depends on the type, concentration and particle size of the tested microplastics. The highest toxicity was observed for PE with inhibition of 12, 99 % for Scenedesmus sp., and 8, 62 % for Chlorella sp., followed by PS, PVC, PP and PET.
