Photodegradation of Organic Materials Used as Biocides.
Abstract
In an effort to evaluate the possible environmental impact of discharging biocide-containing ballast or displacement water from shipboard fuel tanks, a study has been made of the effects of sunlight on the toxicity of three organic biocides to algae. A thiopyridine and a thiocyanate compound in solution in seawater lost most of their toxicity in less than 24 hours exposure to sunlight; a triazine compound was relatively unaffected. The results suggest that it may be possible to select a biocide which is active indefinitely against the microorganisms which infest ships' fuel tanks but becomes degraded so rapidly when discharged that no serious impact of the marine environment would result.
