Influence of microplastics on freshwater bivalves (review)
AI summary Read the abstract
This review synthesized knowledge on how microplastics affect freshwater bivalves, covering ingestion, tissue accumulation, physiological stress responses, and reproductive impacts. Bivalves are shown to be sensitive bioindicators of microplastic contamination in rivers and lakes.
Anthropogenic pollution of the aquatic environment with microplastics is one of the most urgent but least studied problems of modern ecotoxicology. The review, based on recent literature data, provides an analysis of studies in the field of absorption, bioaccumulation, and biological effects of microplastic exposure in freshwater bivalve molluscs (Bivalvia). A total of 22 studies have been conducted so far, which were performed on representatives of three families: Cyrenidae (45), Unionidae (25) and Dreissenidae (30%). The conducted studies are represented by field observations (43.5), field (8.7) and laboratory (47.8%) experiments. It has been shown that freshwater bivalves, as active filters, are able to absorb and accumulate in soft tissues (gills, hepatopancreas) microplastic particles from both water and bottom sediments, perceiving them as food objects. Bioaccumulation of microplastics in molluscs leads to functional and structural disorders in the body. The joint action of microplastics and other pollutants (cadmium, polychlorinated biphenyls, pharmacological drugs) can cause both synergistic and antagonistic effects in the biological responses of molluscs. Based on the conducted studies, it is suggested to use bivalve molluscs as organisms-bioindicators of freshwater pollution with microplastics.

Influence of Microplastics on Freshwater Bivalves (Review)
AI summary Read the abstract
This review analyzed studies on microplastic uptake, bioaccumulation, and biological effects in freshwater bivalves, which serve as both pollution sentinels and vectors for microplastic entry into food webs. The authors found consistent evidence for particle accumulation causing physiological stress, while calling for more standardized exposure protocols to improve cross-study comparability.
