Abstract
2, 4, 6-tribromophenol was detected in the final effluent of a night soil treatment plant in Shizuoka, Japan. The concentration was determined from 0.26μg/l to 0.45μg/l by GC/MS analysis. It was suggested that 2, 4, 6-tribromophenol was formed by bromination of phenol with hypobromous acid, which was produced from bromide ions by treatment with sodium hypochlorite in disinfection process. Relatively high concentration of bromide ions is considered to arise from the ground water used in dilution aerating system, because this plant lies near the sea coast.
