Irgarol 1051 concentrations of up to 1700 ng/L were reported around the Cote d'Azur on the French Riviera (Readman et al., 1993). These high levels were Buy Irgarol 1051 10 µg/mL in Cyclohexane online at LGC Standards, for the highest quality reference standards for environmental analysis and testing. Here, we show the pennate diatom Nitzschia sp. isolated from the East China Sea decreased its photosynthetic performance under the combined influences of two typical marine organic pollutants (Irgarol 1051 and diuron), that are frequently used as biocides to prevent biofouling, and solar UV radiation (UVR). Irgarol 1051, as measured in coastal Western European waters, affect marine phytoplankton performance. The impact of Irgarol was investigated in the phytoplankton species Thalassiosira weissflogii, Emiliania huxleyi, Tetraselmis sp. and Fibrocapsa japonica.EC 50 concentrations for growth, effective quantum yield of Rank Term Type of term Relevance score (tfidf) Class's shr.

With the development of the shipping industry and the increasing number of marine development activities, there will be more and more problems caused by biological fouling. Low level contamination of coastal waters by Irgarol 1051 is reported, the herbicide being present in 85% of the 31 sites sampled.

Irgarol (10.0 μg/l) caused a significant reduction in phytoplankton biomass and primary productivity. HPLC pigment analysis indicated In 2000, a survey was carried out to assess contamination with diuron and Irgarol 1051 of a number of Dutch marinas and coastal waters.

Synonym. Source. Cybutryne. Irgarol is a highly effective biocide used in antifouling coatings to prevent the growth of periphyton. Environmental concentrations of Irgarol in marine and freshwater have often exceeded the effect concentrations of autotrophic organisms tested in the laboratory and give reason for concern that natural periphyton communities may be endangered. Irgarol is a highly specific and effective inhibitor of photosynthesis. This makes it ideal, combined with its very low water solubility, for use in long-life antifouling coatings for marine applicati ons to prevent the growth of algae.
