Experimental ingestion of microplastics in three common Antarctic benthic species

Microplastics (MP) have spread to every corner of the globe, reaching remote areas like Antarctica. Recentstudies detected MP in marine environments, including biota. Benthic organisms suffer negative effects upon MPingestion, leading to impacts on their populations. To address the current knowledge...
