Effects of Spontaneous Fluorescent Polystyrene on Nostocaceae and Daphnia Magna

Microplastic pollution is widespread around the world and inevitably comes into contact with organisms. With accumulation of microplastics in environment, negative impact on organisms has become main focus field microplastics. In this study, different particle concentration effects fluorescent polystyrene (PS-MPs) Nostocaceae Daphnia Magna were researched. The results indicate that PS-MPs adhered to through static electricity, which hindered absorption photons CO2 by Nostocaceae, resulting a decrease chlorophyll, low growth rate high mortality for Nostocaceae. very small particles may be integrated blood Magna, leading an increasing trend spawning rate. research provides basic data reference effect freshwater implications further study
