The organism fate of inland freshwater system under micro-/nano-plastic pollution: A review of past decade.
AI summary Read the abstract
This review synthesized a decade of research on how micro- and nano-plastics affect freshwater organisms including microalgae, macrophytes, zooplankton, benthic invertebrates, and fish, finding that impacts range from impaired photosynthesis and oxidative stress to reproductive disruption and behavioral changes across multiple biological levels.
Micro- and nano-plastics (MPs/NPs) are characterized by their small size and extensive surface area, making them global environmental pollutants with adverse effects on organisms at various levels, including organs, cells, and molecules. Freshwater organisms, such as microalgae, emerging plants, zooplankton, benthic species, and fish, experience varying impacts from MPs/NPs, which are prevalent in both terrestrial and aquatic inland environments. MPs/NPs significantly impact plant physiological processes, including photosynthesis, antioxidant response, energy metabolism, and nitrogen removal. Extended exposure and ingestion to MPs/NPs might cause metabolic and behavioral deviations in zooplankton, posing an extinction risk. Upon exposure to MPs/NPs, both benthic organisms and fish display behavioral and metabolic disturbances, due to oxidative stress, neural toxicity, intestinal damage, and metabolic changes. Results from laboratory and field investigations have confirmed that MPs/NPs can be transported across multiple trophic levels. Moreover, MPs/NPs-induced alterations in zooplankton populations can impede energy transfer, leading to food scarcity for filter-feeding fish, larvae of benthic organism and fish, thus jeopardizing aquatic ecosystems. Furthermore, MPs/NPs can harm the nervous systems of aquatic organisms, influencing their feeding patterns, circadian rhythms, and mobility. Such behavioral alterations might also introduce unforeseen ecological risks. This comprehensive review aims to explore the consequences of MPs/NPs on freshwater organisms and their interconnected food webs. The investigation encompasses various aspects, including behavioral changes, alterations in physiology, impacts on metabolism, transgenerational effects, and the disruption of energy transfer within the ecosystem. This review elucidated the physiological and biochemical toxicity of MPs/NPs on freshwater organisms, and the ensuing risks to inland aquatic ecosystems.

Toxicity of microplastics and nanoplastics for aquatic organisms along the freshwater-marine water continuum.
AI summary Read the abstract
I should note upfront that the abstract provided doesn't include specific findings, just a title and generic text, so I can't accurately summarize what this paper actually discovered. Based on the title alone: this appears to be a review looking at how tiny plastic particles (microplastics and even smaller nanoplastics) harm water-dwelling organisms as they move from rivers and lakes out to the ocean. Understanding this matters because these same waterways are where much of our seafood comes from, and plastic pollution that harms fish and other aquatic life could eventually work its way into the food we eat.
