Single and Combined Effects of Cuso4 and Polyethylene Microplastics on Biochemical Endpoints and Physiological Impacts on the Narrow-Clawed Crayfish Pontastacus Leptodactylus

Biomarker-assisted evaluation of toxicity of co-exposure of emergent pollutants triclosan and microplastics in striped catfish, Pangasianodon hypophthalmus

AI summary · Read the abstract

A 45-day exposure study in striped catfish found that co-exposure to triclosan and polystyrene microplastics suppressed immune function, elevated oxidative stress markers, increased tissue accumulation of triclosan, and caused haematological abnormalities compared to either contaminant alone. The synergistic toxicity observed when microplastics act as vectors for antimicrobial chemicals has implications for aquatic ecosystem health and for the safety of farmed fish consumed by humans.

Ecotoxicological Consequences of Microplastics in Aquatic Life

AI summary · Read the abstract

Researchers reviewed how microplastics — tiny plastic particles under 5mm — harm aquatic ecosystems, documenting that fish, invertebrates, and other marine life can ingest them, leading to physical damage, toxic chemical exposure, and disruptions to feeding and reproduction.

Microplastic Contamination in Aquatic Organisms: An Ecotoxicological Perspective

AI summary · Read the abstract

"This ecotoxicological review examined how microplastics accumulate in aquatic organisms across multiple trophic levels, documenting impacts on physiology, reproduction, and behavior, as well as the transport of associated chemical contaminants through food webs. Because humans sit at the top of aquatic food chains, the bioaccumulation dynamics described here translate directly into dietary microplastic exposure, making ecotoxicological endpoints in fish and shellfish key indicators of human health risk."

Spatial distribution and characterization of microplastics in crayfish from inland waters of Türkiye

AI summary · Read the abstract

Researchers analyzed 200 crayfish from eight Turkish lakes and detected microplastics in 62% of individuals, with significant spatial variation linked to land use and wastewater inputs, and polyethylene and PET fibers and fragments predominating. Freshwater crayfish prove effective bioindicators for mapping microplastic pollution across inland water bodies, revealing how human activity patterns drive contamination of food species consumed by local communities.
