Greenpeace called for an immediate ban on the use of toxic chemicals in ship paint after analyses revealed that they are severely polluting the Mediterranean Sea off the coast of Greece. Research commissioned by Greenpeace of sediment taken from Piraeus and Thessaloniki harbours and the sea close to popular swimming beaches around Salamina island have shown that toxic TBT and other organotin compounds are leaching from the anti-fouling paint used on ships into the Mediterranean Sea.
