Research on microplastic pollution is currently a well-established field and has gone beyond the focus of academia to the general public. It was speculated in 2019 that the amount of microplastics in certain oceanic compartments would double by 2030. On the global point of view, key sources of primary microplastics released into the ocean, are (1) plastic pellets, (2) synthetic textiles, (3) tyres, (4) road markings, (5) marine paints, (6) personal care products and (7) city dust. Paints used for marine application can be damaged or degraded due to several factors, e.g. solar radiation, high salinity, temperature fluctuation, wet-dry cycles, mechanical friction, macro and micro living species. Such processes alter both physical and chemical properties of the paints and most often lead to generation of secondary microplastics. In 2017 marine paints were reported to contributed to 3.7% of global releases of microplastics to the world oceans. The most recent published technical report in 2022 indicated contribution of marine paints as high as 7%. Human exposure to microplastics may occur via ingestion, inhalation and dermal contact due to the presence of microplastics in products, food and air. Annual microplastics consumption, focusing on the American diet, ranges from 39 000 to 52 000 particles depending on age and sex. When inhalation is taken into account, these estimates increase to 74 000 and 121 000. The accumulation of microplastic particles in humans may lead to health risks, e.g. cytotoxicity, hypersensitivity, unwanted immune response, and acute response like hemolysis. As exemplified above, hazards of microplastic pollution needs a call for attention to reduce the plastic debris in marine environment. This report aims to investigate the current literature on the topic of microplastics, with special attention to microplastics from marine coatings in marine eco systems. The conclusion from this study is that research to find alternative coating systems for marine applications and for material in contact with drinking water and food is needed. The authors suggestions are that such research should focus on: • Efforts to produce paint that can be bio-degraded once it become microplastic litter • Efforts to produce plastic free paints with adequate anticorrosion/ antifouling properties. • Efforts to replace toxic, bio-accumulable materials/ ingredients from marine paint formulations
