[Source and fluctuation of trace geosmin and 2-MIB in drinking water of Shanghai].
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.
