The extensive use of the organotin compounds tributyltin (TBT) and triphenyltin (TPT) in ship/boat antifouling paints has created a serious global pollution problem. Consequently, the International Maritime Organisation (IMO) will ban the application of organotin paints by 2008. As a result TBT and TPT are now being replaced by other biocides, with relevance to copper oxide, copper thiocyanate, zinc oxide, zinc naphthenate and zinc pyrithione. The overall goal of this project is to assess the ecological risk posed by the increase environmental concentration of copper and zinc in the Portuguese coast, and compare it with the risks posed by the organotins. The risk assessment will consider both the (i) exposure potential of the organisms to TBT, TPT, copper and zinc in the Portuguese coast and the (ii) effects potential of the above organometals and metals to biota in order to assess the potential to cause adverse impacts in the Portuguese coast.
