Title: Survey of volatile halogenated organics (VHO) in Italy
Abstract: A survey undertaken in Italy (Emilia-Romagna region) has shown that Volatile Halogenated Organics (VHO) are present in many water samples; analysis has been performed by static head-space gas chromatographic technique. In drinking water samples low levels of pollution have become evident before any treatment, while after chlorination with sodium hypochlorite, or chlorine as a gas, VHO have appeared, almost exclusively as trihalomethanes (THM), sometimes at fairly high levels (max = 41.8 μg l−1). Surface water samples have been collected every other month in one year, and have shown different levels of contamination; in most cases VHO (mainly chlorinated solvents) appeared just as traces, seldom at high concentration (max = 263 μg l−1). Swimming pool samples have shown the high levels of contamination (max = 177.4 μg l−1), mainly due to THM, as a consequence of chlorination with sodium hypochlorite. As a matter of fact, it has become evident that VHO pollution is wide-spread in every kind of water; while contamination of surface waters can only involve environmental and aquatic life, contamination especially of drinking waters, and also of swimming pool waters must be controlled as it can directly act on human health.
