The COVID-19 pandemic has exacerbated the problem of environmental contamination disposable personal protective equipment, in particular face masks (FMs). As a result factors, FMs undergo aging and fragmentation processes become source microplastics (MPs) chemical additives. Taking into account scale accumulation used their fragments coastal zone, it should be expected that most appreciable ecotoxicological consequences observed hydrobionts inhabiting ecosystems. Based on this, aim this study was to investigate toxicity leachates from pristine weathered using sperm sand dollars Scaphechinus mirabilis. In our work, we FMs, which for 200 days were kept external environment under natural conditions exposed complex climatic factors.

Microplastic contamination is rapidly becoming an increasingly worrying environmental problem and poses a real threat to marine ecosystems human health. The aim of this research was conduct traditional review the current state art regarding sources MPs in environment, including assessment their toxic effect on organisms transfer within food webs up humans. An extensive literature search (from 1 January 2024 15 February 2025) yielded total 1027 primary articles topic. This overview revealed that can be ingested by organisms, migrate through intestinal wall, spread other organs. They biomagnify along chain carriers chemicals pathogen agents. Exposure lead several risks, tissue damage, oxidative stress, changes immune-related gene expression, neurotoxicity, growth retardation, behavioural abnormalities. toxicity depends mainly particle size distribution composition/characteristics polymer. main routes exposure have been identified as ingestion (mainly seafood), inhalation, dermal exposure. There strong evidence seafood MPs, which pose potential risk study provides basis for assessing MPs’ health impacts.
