La qualità delle acque potabili in relazione allo stato di contaminazione causato da sostanze organoalogenate

In many drinking water treatment plants, the chlorination process is one of the main techniques used for water disinfection. This treatment leads to the formation of trihalomethanes and other halogenated compounds that draw significant scientific attention due to their potential adverse health effects on human beings. The Italian law (D.Lgs. 31/01, referring to EU directive 98/83) fixes restrictive limits (μg/L range) to regulate the concentration of disinfection by-products in drinking water. Considering these limits, in order to assure the drinking water quality, headspace solid-phase micro-extraction (HS-SPME) technique was applied for the organohalogenate compounds analysis. This method shows a good sensibility and precision for the determination of contaminant traces.
