We examined the acute lethal toxicity and multi-generational sublethal toxicity (fecundity and reproduction) of perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA) and salts of perfluoro-1-octansulfonic acid (PFOS) using 1.7% agar Nematode Growth Medium (NGM) plates. The fluorine compounds affected the fecundity of C. elegans at concentrations 105- to 108-fold lower than the median effective concentrations (EC50). In particular, worm abundance during the first generation did not differ significantly from controls, while in contrast, the number of worms in the fourth generation at 10 pM PFOS-tetraethylammonium (TEA) decreased significantly to about 50% of control (p < 0.01) and the number of eggs and worms in the fourth generation at 1 nM PFNA decreased significantly to about 30% of control (p < 0.01). However, no dose-response relationship was observed in this study. We confirmed that perfluoro organic compounds strongly disrupt fecundity in C. elegans.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Health Science v.50(5) p.545-550, 2004","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Pharmaceutical Society of Japan"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1248/jhs.50.545","subitem_relation_type_select":"DOI"}}]},"item_2_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://dx.doi.org/10.1248/jhs.50.545"}]}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11316464","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13449702","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-5207","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tominaga, Nobuaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kohra, Shinya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iguchi, Taisen"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arizono, Koji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-24"}],"displaytype":"detail","filename":"JHS50_545.pdf","filesize":[{"value":"639.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JHS50_545.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/23156/files/JHS50_545.pdf"},"version_id":"097111ab-56bc-404c-adfd-67e09ef36186"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Caenorhabditis elegans","subitem_subject_scheme":"Other"},{"subitem_subject":"sublethal toxicity","subitem_subject_scheme":"Other"},{"subitem_subject":"bioassay","subitem_subject_scheme":"Other"},{"subitem_subject":"perfluoro organic compound","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Effects of Perfluoro Organic Compound Toxicity on Nematode Caenorhabditis elegans Fecundity","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of Perfluoro Organic Compound Toxicity on Nematode Caenorhabditis elegans Fecundity"}]},"item_type_id":"2","owner":"2","path":["56"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-10-12"},"publish_date":"2007-10-12","publish_status":"0","recid":"23156","relation_version_is_last":true,"title":["Effects of Perfluoro Organic Compound Toxicity on Nematode Caenorhabditis elegans Fecundity"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T00:58:45.458089+00:00"}
