Abstract
The overarching aim for the JPI-Oceans project EPHEMARE was to describe uptake, accumulation and effects of microplastics and contaminants associated with microplastics (MPs) in both pelagic and benthic marine organisms. The project had 16 partners from 10 countries and had a focus on the most common MP in the oceans, i.e. LDPE, but also included PET, PP and PVC. Microplastics are expected to accumulate in sediments and this sub-project had a main focus on effects of LDPE on sediment-dwelling organisms. Laboratory exposure experiments were performed with environmentally relevant bivalve species, i.e. the surface deposit-feeding Abra and subsurface deposit-feeding Ennucula. The results show that environmentally relevant concentrations of microplastics affect the metabolism of Abra and Ennucula. A field study in the inner Oslofjord has also been performed. All species sampled in the inner Oslofjord had microplastics in their gut and/or tissues, and the prevalence varied from 5 to 60%.
