| 摘 要： | 采用液液微萃取-气相色谱/质谱联用测定饮用水中痕量异嗅物质--土臭素(geosmin,GSM)和二甲基异冰片(2-Methylisoborneol,2-MIB或MIB).对上海市饮用水水源以及某水厂工艺出水进行调查发现,土霉昧的来源主要为2-MIB,异嗅问题暴发季节为7～10月,7、8月份达到顶峰,原水中2-MIB的最高检出浓度可达152.82 ng/L.水厂出水中最高检出浓度为97.94 ng/L.初步的来源分析推断2-MIB为水中颤藻的代谢产物.

| Abstract: | Liquid-liquid microextraction/GC/MS analysis method was employed in detecting trace odorants in drinking water. A-year-long investigation on odor chemicals was carried out in source water and drinking water in a certain waterworks of Shanghai. The results showed that 2-MIB was the main contaminant which induce disgusting odor to drinking water of Shanghai in July, August, September and October in a year with the peak concentration of 2-MIB 152.82 ng/L in raw water and 97.94 ng/L in finished water from waterworks. Oscillatoria was suspected as the resource of 2-MIB. |
