The results showed a significant decrease in diversty and abundance in the lower, contaminated compartments compared to the upper zones. The results also highlighted that under an increased stress some species progressively increased in number, these were considered PAH-tolerant species such as <em>Odontophora villoti</em>, some others had an occasionally increased in number were considered as opportunistic species, such as <em>Paracomesoma dubium</em> and the species that showed a progressive decreased in number, such as <em>Metoncholaimus pristiurus</em> and <em>Steineria</em> sp., <em>Terschellingia. longicaudata</em>, and <em>Oncholaimellus</em> sp. were classified as PAH-sensitive. Moreover, an increase in the activity of biochemical biomarkers was observed following the exposure of males and gravid females of <em>T. longicaudata</em> to 29, 58 and 87&nbsp;ng&nbsp;g<sup>−1</sup> DW of chrysene and phenanthrene paralleled by a higher vulnerability of the latter demographic category. Besides, a significant decrease in fertility of females and an increase in pharyngeal sucking power were observed for both types of PAHs considered. The sex ratio was also significantly imbalanced in the favor of males, which suggest that chrysene and phenanthrene affect also the hormone system of <em>T. longicaudata</em>. The high affinities of these PAHs and their molecular interactions with both germ line development protein 3 (GLD-3) and sex-determining protein (SDP) may justify these results and explain the toxicokinetic attributes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Ecotoxicity of chrysene and phenanthrene on meiobenthic nematodes with a case study of <i>Terschellingia longicaudata</i>: Taxonomics, toxicokinetics, and molecular interactions modelling","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-01 01:32:21.051987","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2022-11-17","DateCreate":"2022-11-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000878606000002","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.envpol.2022.120459"},"refs":null,"anarec":{"AnaID":359287,"PubliDate":2023,"Pagination":"120459","XtraPublOfAnaID":null,"ISBN":null,"Volume":"316","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42834,"SerRR":"Environmental Pollution.
