[Trihalomethanes and chlorites in finished drinking water in Sardinia (Italy) and possible health effects].
A five years monitoring was carried out in central and southern Sardinia (Italy) to assess the levels of two disinfection by-products (DBPs)--total thrialomethanes (TTHMs) and chlorites--in drinking water Between 1997 and 2002, about 1900 drinking water samples were analysed for both of them. The results showed that TTHMs exceeded very often the maximum admissible concentration. Chlorite concentration was found rising in all the distribution networks since the utilization of chlorine dioxide as disinfectant in 1999, exceeding the maximum contaminant level goals suggested by the World Health Organization. These results are relevant for epidemiological studies on health effects from DBPs exposure.
