Biotransformation Potential and Uncoupling Behavior of Common Benzotriazole-Based Corrosion Inhibitors
Abstract
Benzotriazole and its derivatives form strong complexes with transition metals and are the most widely used type of industrial corrosion inhibitor. Benzotriazole derivatives are present in high concentrations in deicing fluids, industrial cooling water systems, and antifreeze. Benzotriazoles are produced and applied in large quantities; total domestic production was 107(7) kg in 1977, and their use has markedly increased since. A recent USOS reconnaissance of 139 freshwater streams nationwide, found that 1/3 of them contained a single benzotriazole derivative (5- Methylbenzotriazole (MeBT)) in significant concentrations. Benzotriazole derivatives have been implicated as possible carcinogens, endocrine disempters, and plant hormone regulators, but the literature on their biological activity is dated and tenuous. More recently, acute toxic responses to benzotriazoles have been observed in MlCROTOX'M assays at concentrations less than 10 mg/L.
