Both macro- and micro-plastics are found in the ocean, but as yet little is known about their ultimate fate and their impact on marine ecosystems. In this study we present the first evidence that microplastics are already becoming integrated into deep-water organisms. By examining organisms that live on the deep-sea floor we show that plastic microfibres are ingested and internalised by members of at least three major phyla with different feeding mechanisms. These results demonstrate that, despite its remote location, the deep sea and its fragile habitats are already being exposed to human waste to the extent that diverse organisms are ingesting microplastics.<\/p>\n<\/div>\n<\/section>\n<section aria-labelledby=\"introduction\">\n<div id=\"introduction-section\" class=\"serif article-section js-article-section cleared clear\">\n<div id=\"introduction-content\" class=\"pl20 mq875-pl0 js-collapsible-section\">\n<p style=\"text-align: justify;\"><span style=\"font-size: 18pt;\"><strong><span style=\"color: #008000;\">Introduction<\/span><\/strong><\/span><br \/>\nThere appears to be no environment on Earth that has escaped plastic pollution.

If this general observation (albeit based on very few samples), of filter-feeders having lower microplastic loads, holds true more widely, the implication is that deposit-feeding organisms may be more vulnerable to microplastic ingestion than suspension feeders. Of course, load depends on a wide range of factors, such as an animal\u2019s ability to avoid microplastic ingestion, any size or shape-selection of food particles etc. and the abundance and density of microplastics found in an organism\u2019s environment. Knowledge of background microplastic load, systematic surveys with multiple replicates of sediment, seawater collections and sampling of deep-sea organisms across a range of feeding strategies would be required to test if feeding strategy alone impacts organism vulnerability to microplastic ingestion.<\/p>\n<p style=\"text-align: justify;\">Despite microfibres being the majority of microplastic pollution<sup><a id=\"ref-link-section-66\" title=\"Ivar do Sul, J.

All of these facets of the microplastic biological impact problem are relevant to deep-sea organisms however as science knows less about deep-sea biology and ecology (as there are fewer experimental opportunities in this challenging environment) these aspects of marine pollution will be relatively difficult to pursue.

This could suggest that microplastics are transient within the organisms studied. Or, this could be indicative of low densities of microplastics in the deep-sea feeding areas of organisms studied here, or that microfibres have different residency times to other more intensively studied microplastics (e.g. microbeads), or that the organisms here have different gut residency times to other organisms studied. It may also be that certain feeding strategies convey less suspectibility to microplastic bioaccummulation. Given the low number of organisms it was possible to sample here, and without concurrent environmental sampling, the link between background microplastic densities and microplastic abundance within organisms is not possible to establish.<\/p>\n<\/div>\n<\/div>\n<\/section>\n<section aria-labelledby=\"conclusions\">\n<div id=\"conclusions-section\" class=\"serif article-section js-article-section cleared clear\">\n<div id=\"conclusions-content\" class=\"pl20 mq875-pl0 js-collapsible-section\">\n<p style=\"text-align: justify;\"><span style=\"font-size: 18pt;\"><strong><span style=\"color: #008000;\">Conclusions<\/span><\/strong><\/span><br \/>\nStudied organisms have a range of feeding mechanisms, from suspension feeding (sea pens, zoanthids, anemones, barnacles, armoured sea cucumbers) to deposit feeders (sea cucumbers), detritivores and predators (hermit crabs, squat lobsters). Given the breadth of feeding strategies found in deep-sea organisms and their reliance on \u2018marine snow\u2019 (which is the same size fraction as microplastics), and evidence of ingestion in shallow-water counterparts, there is a high likelihood of microplastic ingestion across a wider range of taxa than presented here. However, without the context of environmental sampling of microplastics (water and sediment) or investigations into the impacts of the chemicals ingested, it is not easy to understand the impact microplastic presence will have on biology, and subsequently ecology, of deep-sea organisms. Broadly, the important individual organism effects of microplastic ingestion are being investigated (albeit mostly with microbeads rather than the more commonly found microfibres) but, given the ubiquity of microplastics in our marine environments, research should start considering population and ecosystem level effects<sup><a id=\"ref-link-section-88\" title=\"Browne, M.

Dredge sampling also causes organisms to be in a highly disturbed condition on recovery at the sea surface and trawls are often made of plastic fibres precluding the study of plastic contamination. By using ROVs the exact location and habitat is known, as the collections are made using a suction hose or manipulator arm and deposited into sample containers (bioboxes \u2013 made of plastic but not of the type and colour found). These sampling methods limit the potential for contamination by surrounding sediments and reduce trauma, maintaining the structural integrity of organisms. There is potential for contamination when ascending to the surface in bioboxes as they have some seawater through flow. However this type of contamination (and feeding during ascent) is unlikely and should result in microfibres of similar compositions being found on the external surfaces of the organisms<sup><a id=\"ref-link-section-90\" title=\"Woodall, L.
