Toxicity of Tolyltriazole to Bacillus Microorganisms.
Abstract
The safety of air travel in cold weather depends upon the use of aircraft deicing fluids (ADAF). The environmental and toxic effects of the ADAF component tolyltriazole are not well understood. Tolyltriazole is a potential human carcinogen and has exhibited microbial toxicity in Microtox test. This research used two methods to investigate the toxicity of tolyltriazole on bacillus shaped microorganisms. The first method compared the dissolved oxygen uptake of microcosms exposed to varying concentrations of tolyltriazole. When exposed to 1000 ppm tolyltriazole, all isolated species showed inhibition in respiration. There was no evidence that tolyltriazole at </- 500 ppm had a toxic effect. The second experiment used colony counts to determine if colony formation was inhibited by previous exposure to tolyltriaxole. There was no evidence to suggest that previous exposure to tolyltriazole inhibited colony formation.
