A possible association between quality of drinking water and stomach cancer incidence among native and immigrant populations of a selected industrial city.
The city Zabrze (Upper Silesian Region, Poland) was divided into districts differing in respect to drinking water stations. Geographic correlation between the stomach cancer incidence in native and immigrant populations and the quality of water used for drinking were investigated. It has been shown that in the districts where water of greater hardness has been used for drinking, the stomach cancer incidence was much lower than in other areas, especially in native male populations.
