Effects of antifouling paint components (TBTO, copper and triazine) on the early development of embryos in cod (Gadus morhua L.)

• To assess the risk of antifoulant use to the commercially important cod (Gudus morphua L.). fertilised cod eggs were exposed to triazine, copper and TBTO singly or combined in laboratory tests with running seawater. :fit the highest tested concentrations ( I 1.5 mug Cu l(-1); 5 mug TBTO l(-1)) larval mortality was increased. The highest concentration of triazine ( () ye I) did not cause any significant mortality. Fertilised eggs that had been exposed to all the three chemicals singly for five days shroud a higher buoyancy than the controls. No synergistic or antagonistic effects were indicated. Embryos/larvae exposed to 0.004-0.8 mug TBTO l(-1) did not show any changed respiration compared to the controls after hatching. It is concluded that existing known field concentrations of the three antifoulants are hardly expected to cause detectable effects on fish embryonic/larval development. (C) 2002 Elsevier Science Ltd.
