Reducing antifouling toxins to the Baltic Sea

The coastal ecosystem is of utmost importance to the well-being of the whole of the Baltic Sea. It is vital as the spawning ground and nursery for a wide range of organisms, i.e., fish, algae and invertebrates. It is also important as feeding grounds for pelagic fish and a source of pleasure for the human population. Some 3.5 million leisure boats in the Baltic Sea use the coastal areas for recreational boating. A great majority of these boats use toxic compounds to prevent fouling organisms to attach to the boat hull (antifouling). Today, the most commonly used biocide in antifouling paints is copper oxide but other prohibited compounds such as TBT is still being released to the environment during hull cleaning and maintenance work.

The overall objective of the CHANGE project is to reduce to a minimum the supply of toxic compounds from antifouling paints used on leisure boats in the Baltic Sea. This will be achieved by changing antifouling practices on leisure boats into a sustainable consumption of antifouling products and techniques. For that purpose CHANGE will develop an interdisciplinary and integrated scientific platform of Business administration, environmental law and natural science that will work in close collaboration with stakeholders and end-users to identify the interrelated impacts and driving forces inherent in the problem.
