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). These high levels were För Irgarol är teoretiska beräkningar av halten när fri fas kan uppkomma inte helt relevant eftersom halterna blir orimligt höga långt innan risk för frifas kan förekomma.

Irgarol 1051 is an effective herbicidal biocide mainly used as an antifouling agent in paints for boats and vessels. It is applied at marine as well as at inland freshwater sites. Referring to the technical information provided by the former producer, an amount of Irgarol between 1 - 6 % (on weight-% binder solids) is recommended for marine

This brings us to Irgarol 1051, an antifouling algaecide that is added to boost the performance of the copper biocide in antifouling paint.

Acts as an algaecide. Offers very slow leaching rates, extended antifouling action, low biological activity to animals in general, including fish, shellfish and humans. The toxicity and persistence of antifouling booster biocides are of major concern.
