Abstract

Due to using of nanoplastics in a wide range of applications such as biosensors, photonics, nanocomposites and etc., and highly enhancement of plastic debris in aqueous environments have raised concerns about the potential effects of these substances on microalgae that are primary producers. The aim of this study was, to investigate the effects of different concentrations (0. 25, 2. 5, 25, and 250 mg/L) nanopolystyrene particles (PS-NH2+) after 96 hours on the growth, chlorophyll a content, and amount of antioxidant production of microalgae chlorella vulgaris. The growth rate (counting of cells) and chlorophyll a content and amount of antioxidant (measuring optical density/absorbance) were evaluated. The growth and chlorophyll a content showed a decreasing trend than the control group, with increasing concentration of nanoplastic and exposure time (12 days). Also, the results demonstrated that the amounts of antioxidant production in the exposed samples to nano-polystyrene were higher than the control samples. Finally, it`s suggested that this nanoparticle causes acute impacts on this microalgae in a long time and has the ability to affect cellular mechanisms.
