The distribution of Irgarol 1051 between sediments and water was significantly related to sediment organic carbon content. In addition, significantly higher concentrations of Irgarol 1051 were detected in paint particles than in sediment. The rate of release of Irgarol 1051 from paint residues is very slow, with a half life of approximately 1 y.

Oomori. 1 Faculty of Science, University of the Ryukyus, Okinawa 903-0213, Japan 2 Okinawa Prefectural Institute of Health and Environment, Nanjo City, Okinawa, Jap Occurrence and impacts of a new antifouling biocide Irgarol-1051 (2-methylthio-4-tert- butylamino -6-cyclopropylamino -s-triazine) have been studied in coral reef waters around Okinawa Islands, Japan. The average concentration of Irgarol detected at commercial and fisheries Ports was 24.70 ± 9.88 ng/L. The biocides irgarol and terbutryn enter the wastewater treatment plant (WWTP) via combined sewer systems after leaching from coatings and paints of materials. In this study, the biotransformation of irgarol and terbutryn was examined in aerobic batch experiments with activated sludge taken from the nitrification zone of a conventional WWTP, since currently there is no information about the booster biocides embedded in old paint particles. Therefore, this study attempted to assess the leaching of Dichlofluanid and Irgarol 1051 from. APP collected Organic booster biocides, such as Irgarol 1051®, Sea Nine 211®, dichlofluanid, chlorothalonil, zinc pyrithione, and Zineb are also added to the paint to enhance Dec 10, 2008 These biocides, such as Diuron, SeaNine 211, Dichlofluanid and.

The biocides carbendazim, terbutryn, diuron, and irgarol 1051, and their mixture, were used in two laboratory microcosm and one outdoor mesocosm studies at concentrations of 10, 100, and 1000 ng L1. The water samples were collected in a pond receiving signiﬁcant biocide contamination. No abstract available.

Irgarol 1051 has been widely used as a booster biocide in combination with copper (Cu) in antifouling paints. The combined toxicity of Irgarol with Cu on marine organisms, however, has not been

R. A. Dyer 1 Irgarol 1051 is a diamino-1,3,5-triazine that is 1,3,5-triazine-2,4-diamine carrying a N-tert-butyl, N'-cyclopropyl and a methylsulfanyl group at position 6. It has a role as an antifouling biocide, a xenobiotic and an environmental contaminant. It is an aryl sulfide, a … The toxicity of the anti-fouling biocides tributyltin (TBTO), copper, and Irgarol 1051 (irgarol) at nominal concentrations ranging from 10 to 10,000 microg l(-1) was investigated against the speed of encystment and successful formation of a protective cyst of the cercariae of Parorchis acanthus. For … This work clears that water polluted by the booster biocide Irgarol 1051 which leached out from the antifouling paints will cause high pollution rate in marine environment which leads to cause weak in growth, damage or death of the several phytoplankton species that considered to … Coral reefs are deteriorating worldwide due to various stresses, including pollution of hazardous chemicals such as antifouling chemicals.
