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.

There has been a notable increase in occurrence and intensity of marine heatwaves (MHW) over the past decades, with consequent remarkable risk to vulnerable species as bivalves. This study examines responses farmed Mytilus galloprovincialis 2022 MHW that impacted Northwestern (NW) Adriatic Sea. Expression key transcripts involved functions digestive glands mantles were investigated explore putative acclimatory processes contributing mussel fitness. The was characterized by persistent sea temperature anomalies, elevated salinity, dramatically low chlorophyll-a levels. Despite temporal trends pH extreme seawater temperatures reached July August, carbonate system never undersaturation state, being favourable for bivalve biomineralization. Transcriptional profiles displayed 2-step response. In glands, metabolism lysosomal response functional categories showed an initial decrease (late May), recovery late August. Antioxidant cytoprotective related gene products February August increased expression, strong up-regulations mantles, shell biomineralization prompted stage MHW, likely withstand abrupt changes parameters maintain growth. At high intensities, energy diverted towards stress activation relative mRNA levels transcripts. Results trade-off between core physiological may contribute mussels cope adverse conditions NW
