Ecological Risk Assessment of a Novel Marine Antifoulant


An ecological risk assessment was conducted for the novel marine antifoulant, Sea-Nine™ 211 Biocide. Extensive environmental fate testing and computer modeling of three United States harbor areas resulted in a worst-case Estimated Environmental Concentration (EEC) for Sea-Nine™ 211 Biocide of at least 1.5 orders of magnitude below the Maximum Acceptable Environmental Concentration (MAEC) of 0.63 ug/L obtained from extensive aquatic toxicology testing in a range of aquatic organisms. Overall characterization of the risk of Sea-Nine™ 211 Biocide as the active ingredient in antifoulant paint formulations indicates that use of the chemical is not expected to cause adverse effects to the marine environment.
