Cyanobacterial Extracellular Polymeric Substances Mediated Eco Corona Formation on Micro and Nanoplastics: Mechanisms, Environmental Fate, and Implications for Harmful Algal Blooms

The interaction of micro/nano plastics and the environment: Effects of ecological corona on the toxicity to aquatic organisms.

AI summary · Read the abstract

This review examines how the ecological corona — the layer of organic matter, proteins, and microbes that form on micro- and nanoplastic surfaces in water — affects their toxicity to aquatic organisms. The ecological corona can either increase or decrease toxicity depending on its composition, making real-world plastic hazard assessment more complex than laboratory tests with clean particles suggest.

Coexistence of cyanobacteria and microplastics in eutrophic lake ecosystems: Interactions and combined effects

AI summary · Read the abstract

Microplastics and harmful algae (cyanobacteria) often build up together in polluted lakes, and this review of existing research shows they actually affect each other, plastics stress out the algae, while algae can coat plastics and change how they break down or sink. This combo appears to make lake pollution worse for fish and other wildlife than either problem alone, which matters since these same lakes can be sources of drinking water and food, meaning the risks to human health may be greater than previously understood.

A brief overview of the interaction between micro/nanoplastics and algae

AI summary · Read the abstract

This review synthesizes research on how micro- and nanoplastics harm algae — disrupting growth, pigmentation, photosynthesis, and oxidative balance — while also exploring algae as a promising eco-friendly method to remove plastic particles from water. Because algae anchor aquatic food webs as primary producers, MNP-driven algal stress cascades upward through trophic levels, ultimately threatening ecosystem health and human seafood safety.

Impacts of Biofilm Formation on the Physicochemical Properties and Toxicity of Microplastics: A Concise Review

AI summary · Read the abstract

Researchers reviewing biofilm formation on microplastics found that microbial colonization alters the particles' surface chemistry, density, and pollutant adsorption capacity, ultimately affecting how microplastics are ingested by organisms and how they influence nutrient cycling in aquatic ecosystems.
