Desorption efficiency of perfluorinated compounds from microplastics in a model considering digestion in fish and humans
Micro-plastics (MP) are fragments of plastic less than 5 mm in size formed, among other things, by the breakdown of plastics when exposed to external conditions. Perfluorinated compounds belong to a group of persistent organic pollutants released into the marine environment, which pose a serious threat to the health and life of many marine organisms. The research proposed in this project will help us understand the potential impact of MP on selected links in the food chain and its role in the transport of selected organic pollutants. Fish and seafood constitute an important part of the balanced diet of many people. At the same time, these organisms are particularly vulnerable to exposure to MP, which when entering the gastrointestinal tract can release previously adsorbed contaminant molecules, potentially increasing the pool of contaminants entering marine organisms. Research is needed to allow us to determine the efficiency of the process of adsorption of organic compounds on the MP surface and subsequent desorption through digestive processes. The research is designed to reveal the efficiency of transfer of perfluorinated compounds from the MP surface to the fish and human body and what percentage further remains on the MP surface and can re-enter the environment.
