[Evaluation of the quality of drinking water in Senigallia (Italy), including the presence of asbestos fibres, and of morbidity and mortality due to gastrointestinal tumours].

The aim was to evaluate the organoleptic quality of drinking water conducted in asbestos cement piping, in eleven towns in the Marche region (Italy) and the presence of asbestos fibres. A descriptive survey was also conducted to assess possible health effects in the population, in particular morbidity and mortality due to gastrointestinal (GI) cancer. Study results show a very low concentration of free asbestos fibres in water samples examined.
