Environmental distribution, transport and ecotoxicity of microplastics: A review
AI summary Read the abstract
This review covers the environmental distribution and transport of microplastics across marine, freshwater, soil, and atmospheric compartments, and analyzes their toxicity to organisms at different trophic levels including potential effects on human health.
Microplastics (MPs) have become a global environmental pollutant because of their unique properties. The extensive MP toxicity reports have focused on the aquatic environment, while the pervasive MP contamination in the soil and air has largely been overlooked. This review summarizes the abundance, sources and transport of MPs in different environments. It analyzes the toxicity of MPs based on various environmentally relevant bacterial, cellular, plant, aquatic animal and mammalian test groups, using both in vitro and in vivo experiments. The combined toxicity effects of MPs and various other environmental pollutants on ecosystems are also discussed. Currently, data on the adverse effects on combined MP toxicity are very limited. Thus, a systematic assessment of the environmental risk in different environments and in various species from MPs is challenging. Thus, this review proposes the possible risks and identifies the knowledge gaps posed by MPs to food safety and human health.

A review of microplastics in the aquatic environmental: distribution, transport, ecotoxicology, and toxicological mechanisms
AI summary Read the abstract
This review examines how microplastics are distributed, transported, and accumulate throughout aquatic environments, and the toxicological effects they have on aquatic organisms. The study suggests that microplastics can affect human health through the food chain, but notes that understanding of combined toxicity mechanisms remains very limited. The authors identify significant knowledge gaps and call for more systematic environmental risk assessments across multiple species.
