Microplastics (MPs) have emerged as a significant global concern, having permeated the most remote reaches of the world. MPs have been detected in Arctic pack ice, seawater and seafloor sediments, but limited information exists on the mechanisms underlying their distribution and the scale of contamination. MPs may be expected to settle out over time onto sediments, where they will ultimately be buried. Ingestion of MPs by numerous species have been documented across the various habitats around the world, from benthic to pelagic and across all levels of the marine food web. Laboratory-based studies suggest the potential for significant harm associated with MP ingestion, although the real-world health consequences for sealife remains unclear.
