非有機スズ系代替船底防汚塗料の開発状況と水生生物に対する有害性評価 Present status on the development of alternative tributyltin-free antifouling paints and toxicity of new biocides to aquatic organisms - Review - Yamada, Hisashi 2785 山田, 久 ヤマダ, ヒサシ Kakuno, Akira 462 角埜, 彰 90371963 カクノ, アキラ TBT compound; anrifouling paint; biocide; aquatic organisms; toxicity; risk assessment The present status on the development of an alternative tributyltin (TBT) -free antifouling paints was reviewed in order to consider the hazardous effects of new biocides to aquatic organisms. Although 15 organic chemicals and cuprous oxide were selected for a biocide in the alternative organotion-free antifouling paints and the antifouling agents for fishing net, bis- (1-hydroxy-2 (H) -pyridine thionate-O,S) zinc (zinc pyrithion; ZnPT) and bis- (1-hydroxy-2 (H) -pyridine thionate-O, S) copper (copper pyrithion; CuPT), 4,5-dichloro-2-n-octyl-3-isothiazolone (Seanine-211), pyridinetripehnylboron (PyB), and 2-methylthio-4-t-butylamino-6-cyclopropylamino-s-triazine (Irgarol 1051) were mainly used in the newly developed anti-fouling paint. These organic chemicals were used with cuprous oxide in order to improve the anti-fouling efficiency. Irgarol 1051 was detected in water collected at several regions of Japan and Europe, however, other chemicals were not detected in the aquatic environment. Acute toxicity of ZnPT, CuPT, Seanine-211, PyB, and Irgarol 1051 on aquatic organisms was 2~1,780 µg/L, 4.3~43.6 µg/L, 2.7~1,312 µg/L, 2.15~242 µg/L, and 0.1~12,000 µg/L, respectively. These chemicals showed the almost same acute toxicity as TBT. As these chemicals are not stable and persistent, it is suggested that the risk of alternative biocides to aquatic organisms is smaller than TBT. departmental bulletin paper 水産総合研究センター 2003-03 VoR application/pdf 水産総合研究センター研究報告 6 56 72 Bulletin of Fisheries Research Agency AA11589591 1346-9894 https://fra.repo.nii.ac.jp/record/2010791/files/fra_k_6_56.pdf https://fra.repo.nii.ac.jp/records/2010791 jpn fra_k_6_56 日本農学文献記事索引（AgriKnowledge） https://agriknowledge.affrc.go.jp/RN/2010671197 open access
