Abstract: This study investigated the effects of microplastics (MPs) on Skeletonema costatum growth by monitoring algal responses to polystyrene MPs (0.1 μm diameter) at concentrations of 0.10 mg/L and 10.00 mg/L. Results demonstrate that the addition of MPs plays an important role in algal growth, chlorophyll and oxidative stress. After three days of MP exposure, both low and high concentration exposures significantly increased cell growth and chlorophyll content, with pronounced effects observed under the low concentration exposure. Additionally, MP exposure markedly elevated superoxide dismutase (SOD) activity, indicating a physiological stress response in algal cells. Collectively, this work establishes critical data for assessing the impacts of MPs on marine phytoplankton in marine ecosystems.
