Chemistry and Fate of Organotin Antifouling Biocides in the Environment
Organotin antifouling paints are degraded relatively rapidly in seawater mainly by microorganisms, but they have high affinities to sediment and...
-
Toxicity and Preliminary Risk Assessment of Alternative Antifouling Biocides to Aquatic Organisms
Published literature has been reviewed regarding the toxicity of representative alternative antifouling biocides (Chlorothalonil, Dichlofluanid,...
