摘要: This study presents the seasonal and spatial variations of trihalomethanes (THMs) haloacetic acids (HAAs) in 30 sampling points within three water distribution systems Istanbul City, Turkey. The effects surface quality, variation, species differences were examined. occurrence chlorinated THMs HAAs levels was considerably lower system which raw is subjected to pre-ozonation versus pre-chlorination. Seasonal analysis data indicated that median concentration four (THM4) higher than nine (HAA9) concentrations all points. For monitored, highest THM4 HAA9 observed spring summer season, while lowest these disinfection byproduct (DBP) compounds obtained fall winter period. Due level bromide supplying waters two systems, moderate brominated DBP spe...
