I reviewed published literature reporting the behaviour, occurrence, and toxicity in aquatic environments of the organotin-free new antifouling biocides. Our analysis included the representative alternative new biocides; 2,4,5,6-tetrachloro-isophthalonitrile（chlorothalonil）, N’-dimethyl-N-phenylsulphamide（dichlofluanid）, 1-（3,4-dichlorophenyl）-3,3-dimethylurea（diuron）, 2-methylthio-4-t-butylamino-6-cyclopropylamino-s-triazine（Irgarol 1051）, 4,5-dichloro-2-（n-octyl）-4-isothiazoline（Sea Nine 211）, 2- （thiocyanomethylthio）benzothiazole（TCMTB）, bis-（1-hydroxy-2（1H）-pyridinethionate-O,S） zinc（zinc pyrithione, ZnPT）, zinc ethylene bis-（dithiocarbamate）（zineb）, pyridinetriphenylboron（PK）, and bis-（1-hydroxy-2（1H）-pyridinethionate-O,S） copper（copper pyrithione, CuPT）. These new biocides are classified as “toxic to very toxic” according to guidelines of the Organization for Economic Co-operation and Development, with toxicity values similar to those of TBT. The new biocides are decomposed by hydrolysis, photolysis, and biological activity and thus are less persistent in the environment than TBT, but low vapour pressure limits their evaporation. Because of medium octanol-water coefficient（Kow） and organic carbon partitioning coefficient（Koc） values, these new biocides, except for zineb, ZnPT, and CuPT, tend to be distributed in both seawater and sediments but have low bioaccumulation in aquatic organisms. Chlorothalonil, dichlofluanid, diuron, Irgarol 1051 and its degradation product, 2-methylthio-4-tert-butylamino-6-amino-s-triazine（M1）, and Sea Nine 211 have been found in natural waters, with higher concentrations in marinas and small harbours for fishing boats than in coastal waters, but insufficient data are available to assess contamination by these biocides. The reported concentrations of Irgarol 1051, M1, and Sea Nine 211 exceed their respective predicted no-effect concentration values, especially in marinas and fishery harbours, suggesting that these new biocides are already harming aquatic ecosystems in some areas. Further research is needed to assess the ecotoxicological risks of these biocides and to develop methods for estimation of their concentrations in ambient water.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"有機スズ化合物（TBT） の代替新規防汚物質の水域環境における挙動や濃度，水生生物に対する有害性を既往文献情報に基づき取りまとめるとともに，得られた情報により水域生態系に対するリスクを予察した。新規防汚物質の有害性は TBT に匹敵するが，分解しやすく，環境リスクは TBT より小さいと推察された。しかし，Irgarol 1051及び Sea Nine 211の海水中濃度が無影響濃度を超えるため，リスク評価研究の深化の必要性を指摘した。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_k_21_31","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"日本農学文献記事索引（AgriKnowledge）"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010751347","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11589591","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-9894","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"https://isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Yamada, Hisashi","creatorNameLang":"en"},{"creatorName":"山田, 久","creatorNameLang":"ja"},{"creatorName":"ヤマダ, ヒサシ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Yamada","familyNameLang":"en"},{"familyName":"山田","familyNameLang":"ja"},{"familyName":"ヤマダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Hisashi","givenNameLang":"en"},{"givenName":"久","givenNameLang":"ja"},{"givenName":"ヒサシ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2785","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-02"}],"filename":"fra_k_21_31.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010854/files/fra_k_21_31.pdf"},"version_id":"c9844ae2-d2cb-48a1-aa98-e7e854b6dfb8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"TBT-free antifouling paint; biocide; fate in environment; toxicity; risk assessment; aquatic organisms","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"新規防汚物質の水域環境における挙動、汚染状況及び水生生物に対する有害性並びに水域生態系に対する予備的リスク評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"新規防汚物質の水域環境における挙動、汚染状況及び水生生物に対する有害性並びに水域生態系に対する予備的リスク評価","subitem_title_language":"ja"},{"subitem_title":"Behaviour, Occurrence, and Aquatic Toxicity of New Antifouling Biocides and Preliminary Assessment of Risk to Aquatic Ecosystems","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1724310837549"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-02"},"publish_date":"2024-10-02","publish_status":"0","recid":"2010854","relation_version_is_last":true,"title":["新規防汚物質の水域環境における挙動、汚染状況及び水生生物に対する有害性並びに水域生態系に対する予備的リスク評価"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-01-29T06:24:15.939983+00:00"}
