Abstract
By taking tap water samples from every district and county in Shanghai, we analyze six types of inorganic anions contained in these water samples, namely Cl-, Br-, NO3-, NO2-, PO43- and SO42-, by applying the Ion Chromatography System. The results indicate that among these six inorganic anions in Shanghai tap water, Cl- has the highest concentration while NO2- the lowest. Using the Nemerow Index in evaluating the inorganic anions in Shanghai tap water, we find that the average compliance rate of tap water in Shanghai is 58.3 percent, and that phosphorus pollution is serious. When PO43- is not calculated, tap water in Shanghai can be labeled as light pollution in general, from the suburbs to city areas tending to be cleaner; when PO43- is calculated, tap water in Shanghai is moderately polluted, and pollution in coastal areas is more serious than in inner areas.
