This experimental methodology has been applied to cultured benthic foraminifera <i>Rosalina globularis</i>, and to <i>in situ</i> foraminifera collected in a plastic remain found buried into superficial sediment in the Mediterranean seafloor, <i>Rosalina bradyi</i>, <i>Textularia bocki</i> and <i>Cibicidoides lobatulus</i>. <i>In vitro</i> foraminifera were treated with bis-(2-ethylhexyl) phthalate (DEHP) molecule to explore its internalization in the cytoplasm. Benthic foraminifera are marine microbial eukaryotes, sediment-dwelling, commonly short-lived and with reproductive cycles which play a central role in global biogeochemical cycles of inorganic and organic compounds. Despite the recent advances and investigations into the occurrence, distribution, and abundance of plastics, including microplastics, in marine environments, there remain relevant knowledge gaps, particularly on their effects on the benthic protists. No study, to our knowledge, has documented the molecular scale effect of plastics on foraminifera.Our analyses revealed three possible ways through which plastic-related molecules and plastic debris can enter a biogeochemical cycle and may affect the ecosystems: 1) foraminifera <i>in situ</i> can grow on plastic remains, namely <i>C. lobatulus</i>, <i>R. bradyi</i> and <i>T. bocki</i>, showing signals of oxidative stress and protein aggregation in comparison with R. globularis cultured in negative control; 2) DEHP can be incorporated in the cytoplasm of calcareous foraminifera, as observed in <i>R. globularis</i>; 3) microplastic debris, identified as epoxy resin, can be found in the cytoplasm and the agglutinated shell of <i>T. bocki</i>.We hypothesize that plastic waste and their associated additives may produce modifications related to the biomineralization process in foraminifera. This effect would be added to those induced by ocean acidification with negative consequences on the foraminiferal biogenic carbon (C) storage capacity.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Plastics, (bio)polymers and their apparent biogeochemical cycle: an infrared spectroscopy study on foraminifera","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-26 01:32:04.578251","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Plastics, Marine pollution, Foraminifera, FTIR, Cellular stress","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-07-13","DateCreate":"2021-07-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000647790400020","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.envpol.2021.116912"},"refs":null,"anarec":{"AnaID":340003,"PubliDate":2021,"Pagination":"116912","XtraPublOfAnaID":null,"ISBN":null,"Volume":"279","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42834,"SerRR":"Environmental Pollution.
