ABSTRACT

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 concem 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.
