Abstract

A method is described for the determination of the rate at which compounds of the toxic metals, copper and mercury, leach into sea water from anti‐fouling compositions. The method is suitable for stations where sea water is not directly accessible. Colorimetric procedures for the determination of copper and mercury in sea water arc described, and such aspects as the state in which the toxic metals arc dissolved, and the stability of the leachates, are dealt with. The practical implications of the functioning of anti‐fouling compositions, and the maintenance of a sufficiently high leaching rate arc discussed, special reference being made to the work of U.S. investigators at the Woods Hole Marine Biological Laboratories.
