Sammanfattning

In the Marine Paint Optimization project a broad range of settling tests are used to assess the efficacy of antifoulants, in order to provide a basis for the subsequent development of optimized antifoulant mixtures. Since the fouling community is very complex, and composed of a large number of different species with vastly different sensitivities to the different antifoulants, the test approach has been to select key organisms from all the main fouling groups. By doing so the whole sensitivity range of the fouling community is captured. The “test battery” includes invertebrate larvae (barnacles (Amphibalanus improvisus), sea squirt (Ciona intestinalis) and bryozoans (Bugula neritina)) macro algae (sea lettuce (Ulva lactuca)) and biofilms (periphyton community, also referred to as slime). The sensitivity range for each individual species has been tested for a list of antifouling compounds, either in use today or likely to be registered and approved by the European Biocidal Product Directive, including Medetomedine, Copper Pyrithione, Zinc Pyrithione, Tolylfluanid, Sea-Nine (DCOIT), Copper, Borocide (TPBP) and Irgarol. EC99 for all tested species and biocides will be presented. This study is a part of the Marine Paint research programme funded by MISTRA.
