A method for microextraction and GC-ECD analysis specific for volatile disinfection by-products (DBPs) in drinking water was optimized based on US EPA Standard Method 551. The method was validated in terms of linearity, recovery, and detection limit and was found to be linear over a wide concentration range (5.00- 250 µg/L) with acceptable recoveries (70- 110% at the 150.0 µg/L level in water). The optimized method was used to determine the levels of volatile DBPs in water samples from various sources in Metro Manila. The DBPs found in the water samples were chloroform (18 - 379 µg/L), bromodichloromethane (2.6 - 9.5 µg/L), dichloroacetonitrile (5.6 - 157 µg/L), dichloroacetone (0.86-1.7 µg/L), trichloroacetone (1.6 - 7.3 µg/L), and bromochloroacetonitrile (1.7 - 1.9 µg/L). The level of chloroform in the samples exceeded guideline values for total trihalomethanes as set in most countries. The levels of the brominated DBPs were also very low compared to those of the chlorinated analogs.Downloads
