Calling out for studying microplastics at environmentally relevant conditions: aquatic distribution, differential impacts on microalgae by aged and pristine microplastics, and mechanisms of altered toxicity

Persistent Microplastics in Ecosystem: The Role of Microalgae-Microplastic Interactions

AI summary · Read the abstract

This review examines interactions between microalgae and microplastics in aquatic environments, focusing on how algae can adsorb, ingest, and respond to plastic particles, and how these interactions affect microplastic persistence and transport. Microalgae form the base of aquatic food webs, so their uptake of microplastics initiates the trophic transfer chain that ultimately delivers plastic particles and associated chemical contaminants to human consumers through seafood.

Microplastics and freshwater microalgae: what do we know so far?

AI summary · Read the abstract

A review of 20 studies found that microplastics inhibit freshwater microalgae growth, reduce photosynthetic activity, alter pigment profiles, and induce oxidative stress, with effects varying by plastic shape, size, concentration, and exposure duration. Because microalgae form the base of aquatic food webs, microplastic-driven disruption of algal communities could have cascading effects on freshwater ecosystem health.

Evidence that microplastics at environmentally relevant concentration and size interfere with energy metabolism of microalgal community

Marine Microplastics: Abundance, Ecotoxic Consequences of Associated Anthropogenic Contaminants and Interactions with Microorganisms

AI summary · Read the abstract

Researchers reviewed the rapid growth of microplastic pollution in the ocean, highlighting how these particles accumulate toxic chemicals and interact with microorganisms in ways that amplify their ecological harm. As plastic production continues to rise, the marine food web faces increasing exposure to contaminated microplastics that can ultimately reach humans through seafood.

Occurrence and Ecotoxicological Effects of Microplastics on Aquatic and Terrestrial Ecosystems

AI summary · Read the abstract

Researchers reviewed how microplastics — now present in the water we drink, the food we eat, and the air we breathe — accumulate in and harm both aquatic and land-based ecosystems, highlighting the broad reach of plastic pollution as a threat to wildlife and potentially to human health.
