This brings us to Irgarol 1051, an antifouling algaecide that is added to boost the performance of the copper biocide in antifouling paint. Irgarol (listed as NCN in the Booster column of the accompanying tables) first earned approval from the EPA in 1994, and was introduced in bottom paint in 1998. A previously unknown s-triazine species present in commercially available Irgarol-1051, a booster biocide additive in copper-based antifouling paints for the replacement of organotin-based antifoulants, has been identified in the coastal aquatic environment.

The highest concentrations were found in the Norfolk and Suffolk Broads in May. The rivers Great Ouse, Wissey, Bure and Yare also contained all three compounds, as did the Great Ouse Cut-off Channel.

Five different enzyme-linked immunosorbent assays (ELISAs) have been developed and applied for the detection of five representatives of important families of chemical pollutants in seawater: Irgarol 1051® (triazine biocide), sulfapyridine and chloramphenicol (antibiotics), 17β-estradiol (hormone), a … Overlapping and unique toxic effects of three alternative antifouling biocides (Diuron, Irgarol 1051 ®, Sea-Nine 211 ®) on non-target marine fish Ecotoxicol Environ Saf . 2019 Sep 30;180:23-32. doi: 10.1016/j.ecoenv.2019.04.070.

Irgarol 1051 (2-methythiol-4-tert-butylamino-6-cyclopropylamino-s-triazine) is an algaecide commonly used in antifouling paints. It undergoes photodegradation which yields M1 (2-methylthio-4-tert-butylamino-6-amino-s-triazine) as its major and most stable degradant.

2-methythiol-4-tert-butylamino-6-cyclopropylamino-s-triazine (Irgarol-1051) has been widely used as effective alternative antifouling paint in marine structures including ships. However, it has been causing deleterious effects to marine organisms including reef building corals. The main objective of this study was to establish baseline levels of Irgarol-1051 around coral reefs and nearby

Contamination of coastal waters by booster biocides was first reported in the early 1990s. Irgarol 1051 concentrations of up to 1700 ng/L were reported around the Cote d'Azur on the French Riviera (Readman et al., 1993).

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

Author information: (1)Institute of Oceanography and Environment, University of Malaysia Terengganu, 21030 Kuala Terengganu, Malaysia. hassanrashidali@yahoo.com 2016-08-15 · The coastal areas including the coral reef ecosystems have been ubiquitously contaminated with antifouling biocide Irgarol 1051. However, the levels are not at alarming in terms of acute toxicity. • The main possible sources of Irgarol 1051 are shipping/boating activities at the port and dockyard and tourism activities. • 2013-05-15 · Irgarol-1051 is very effective in prevention of attachments of biofoulings in recreational boats and yachts (Gardinali et al., 2002, Knutson et al., 2011).

It undergoes photodegradation which yields M1 (2-methylthio-4-tert-butylamino-6-amino-s-triazine) as its major and most stable degradant. (e.g. Irgarol 1051) and personal care products such as the anti‑dandruff agent zinc pyrithione. Contamination of coastal waters by booster biocides was first reported in the early 1990s. Irgarol 1051 concentrations of up to 1700 ng/L were reported around the Cote d'Azur on the French Riviera (Readman et al., 1993).
