Optimization of Analytical Methods for the Determination of Dbps: Application to Drinking Waters From Konya-turkey

Chlorine disinfection is a generally used process for eradication pathogenic microorganisms from drinking water to prevent water-born diseases. It has been demonstrated that natural organic matter (NOM) in raw water may react with chlorine to form disinfection by-products (DBPs) which are carcinogenic or mutagenic. The occurrence of disinfection by-products (DBPs) in drinking water has been an issue of major concern during the last years due to their adverse health effects. The development and optimization of analytical methods for the determination of DBPs in water are key points in order to estimate human exposure to DBPs after water treatment. During this study, analytical methods for the determination of major categories of DBPs haloacetonitriles, haloketones, chloral hydrate and chloropicrin were optimized and evaluated in order to be applicable for the routine analysis of these compounds in drinking water. Application of the methods to water samples from Konya-Turkey was performed in order to determine the formation potential of the DBPs studied during chlorination. Mostly found disinfection by products in water treatment plant and water distribution network are 1,2-Dibromoethane, trichloroethene, 1,1,1-Trichloroethane, Dichloroacetonitrile and Bromochloroacetonitrile.
