Microplastics da aka kama a cikin samfuran sun bambanta da girman daga 0.03 millimeters zuwa 4.6 millimeters. Za'a iya bincika barbashi na microplastic ƙanana kamar 0.03 millimeters ta hanyoyin ladabi masu ladabi. A sakamakon haka, babban adadin microplastics: a matsakaita, an gano 4,789 a kowace mita cubic na ruwa.
An sami mafi girman taro (26,334) kusa da Afirka ta Kudu, sannan gefen tashar Ingilishi kusa da Brest, Faransa (17,184), sannan wani maki kusa da Afirka ta Kudu (14,976) sannan Tekun Balearic (14,970) kuma a cikin Tekun Arewa a bakin tekun Denmark (14,457). Don haka, uku daga cikin manyan wurare biyar na duniya don gurɓatar microplastic na ruwa suna cikin Turai. Babban ayyukan ɗan adam a cikin yankuna yana haifar da haɓakar microplastics a cikin ruwayen da ke kewayen Turai, Brazil da Afirka ta Kudu. Duk da haka, ba a san dalilan da ke tattare da babban taro a cikin Tekun Kudu ba. Har ila yau, ba a bayyana ko microplastics suna tafiya kudu daga Kudancin Tekun zuwa Antarctica ba.
Har ila yau binciken ya tantance nau'in samfurin filastik da microplastics ya samo asali daga. An gano cewa, a matsakaita, 71% na microplastics a cikin samfurori sune microfibers, daga kayan aiki irin su polyester, wanda aka saki a cikin yanayi daga injin wanki (ta hanyar ruwa mai tsabta), bushewa (a cikin iska), zubar da kai tsaye daga.
