Contrary to widespread assumptions, PLA microplastics demonstrate comparable or even enhanced toxicity compared to conventional microplastics in multiple biological systems. Recent peer-reviewed studies reveal that PLA microplastics reduced survival rates in aquatic organisms to 52.4% compared to 85.7% for PET microplastics, caused more severe oxidative stress in earthworms than polyethylene, and inhibited algae growth by 47.95% - the highest rate among all tested plastics.
