The substance is not readily biodegradable. However, if the substance is dechlorinated during use and/or discharge to STPs, its dechlorination product Benzenesulphonamide (BSA) will be readily biodegradable. A 90% dechlorination under realistic application conditions was verified in 0.01 and 0.1 g/L aqueous solutions within 0.5 and 14 hours, and after application of 50 g/L onto surfaces for disinfection purpose (residual chlorine up to 50 cm above ground: < 0.025 ppm).
