Microplastic contamination of the drilling bivalve Hiatella arctica in Arctic rhodolith beds

Abstract There is an increasing number of studies reporting microplastic (MP) contamination in the Arctic environment. We analysed MP abundance in samples from a marine Arctic ecosystem that has not been investigated in this context and that features a high biodiversity: hollow rhodoliths gouged by...
