Abstract
Evolution of 46 disinfection by-products (DBPs) and organic compounds have been monitored in the Treatment and Distribution System of drinking water of Córdoba (Spain). All the compounds investigated were included into five categories: aldehydes and ketones, trihalomethanes, halonitromethanes, halo-acetonitriles and haloacetic acids. In this way, only the half were detected in our study. Aldehydes-ketones and haloacetic acids were found in raw water not being then DBPs strictly, while THM, halonitro-methanes and haloacetonitriles appeared during treatment. Finally, all the DBPs detected showed much lower levels than those of the international standard consulted, that implying a very safety to consumer.
