A sampling has been undertaken to investigate the variation of haloacetic acids formation and nature organic matter through 81 samples were collected from three water treatment plant and three major rivers of Tehran Iran. Changes in the total organic matter (TOC), ultraviolet absorbance (UV254), specific ultraviolet absorbance (SUVA) were measured in raw water samples. Haloacetic acids concentrations were monitored using a new static headspace GC-ECD method without a manual pre-concentration in three water treatment plants. The average concentration of TOC and HAAs in three rivers and three water treatment plants in spring, summer and fall, were 4, 2.41 and 4.03 mg/L and 48.75, 43.79 and 51.07 μg/L respectively. Seasonal variation indicated that HAAs levels were much higher in spring and fall.
已进行采样以研究伊朗德黑兰的三个水处理厂和三条主要河流中卤乙酸形成和天然有机物的变化。在原水样品中测量总有机碳 (TOC)、紫外线吸收率 (UV254) 和特定紫外线吸收率 (SUVA) 的变化。使用新的静态顶空 GC-ECD 方法在三个水处理厂中无需手动预浓缩即可监测卤乙酸浓度。三个河流和三个水处理厂在春季、夏季和秋季的 TOC 和 HAAs 平均浓度分别为 4、2.41 和 4.03 mg/L 和 48.75、43.79 和 51.07 μg/L。季节性变化表明，春季和秋季的 HAAs 水平要高得多。
