Show moreThis thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research. Specifically, the thesis addresses the topic of microplastics in the freshwater environment. The research presented covers both the environmental presence and abundance of microplastics, in addition to ecological effects, investigated using observational and experimental studies. These studies give a greater understanding of the abundance, types and sources of microplastics in freshwater systems in the UK, how organisms and chemicals interact with microplastics and the potential ecological effects on a range of freshwater organisms from different functional feeding groups and trophic levels.

Show moreThe sources of microplastics in the oceans—and in the Mediterranean Sea—are multiple. One of the sources are microplastics that are added to cosmetic products. Several states have adopted national bans on microplastics in rinseoff products. Before EU regulation might accomodate a ban on microplastics in cosmetics, the REACH Regulation has to be amended to include the registration, evaluation and, if necessary, restrict the use of polymers as chemical substance in certain products. Informing consumers about microplastics in cosmetic products, for example by labelling, remains essential as long as there is no ban on microplastics. Show less
