%X Disinfection by-products and perchlorate in the raw water and finished water of Beijing's a drinking water plants were investigated. The results indicated that there was little bromate in the drinking water. Five haloacetic acids (HAAs) were found in the water. The concentrations of the sum of the five HAAs were ranged from 42.1 micrograms/L to 149.5 micrograms/L. In the HAAs, the chlorine-containing HAAs accounted for more than 90% of the total HAAs. In the five HAAs, the concentration order of the HAAs were trichloroacetic acid > dichloroacetic acid > bromochloroacetic acid > dibromoacetic acid > bromodichloroacetic acid. The HAAs in Beijing's drinking water were much influenced by the variation of season. They had the highest concentrations in September and lowest concentration in April, respectively. For perchlorate in Beijing's drinking water, it was greatly influenced by the groundwater. Its concentrations were between 0.1-6.8 micrograms/L in the finished drinking water. It had peak value in November and minimum value in July, respectively.
