Today, plastics have been used in many areas and their use have been increasing day by day. This increase in the use of plastic causes environmental pollution as well as negatively affects organisms in the environment and therefore human health. Plastics reach to the water environment through different transport routes. Microplastics that have reached to the water environment are consumed by aquatic organisms. Microplastics in aquatic species (fish, mussels, shrimp, seals, etc.) were highlighted in many studies. Microplastics consumed by aquatic organisms are included in the food network, reaching as far as human consumption. Therefore, the importance of the subject have been emphasized, the evaluation of the studies on microplastics and the risks it poses have been examined in this compilation study which was carried out in order to raise awareness about this issue and to ensure that the necessary measures will be taken.
