This review examines how microalgae can remove microplastics from wastewater alongside producing biofuels, combining pollution remediation with energy generation. Microalgal systems could offer a dual-benefit approach to reducing plastic contamination in water treatment effluents.
Microplastics leachate may play a more important role than microplastics in inhibiting microalga Chlorella vulgaris growth at cellular and molecular levels
Researchers found that chemical compounds leaching from aged microplastics may be more harmful to algae than the microplastic particles themselves. UV-weathered polyethylene and PVC released substances that inhibited algae growth, caused oxidative stress, and altered gene expression more severely than direct particle exposure. The study suggests that the chemicals released by degrading microplastics deserve more attention as a source of aquatic toxicity.
