Detection of Fluoride Content in Drinking Water of Cangzhou City

[Objective]To identify the background value of fluoride content in the drinking water of Cangzhou City,and provide basic data for detecting the adulteration in milk with fluoride selective electrode method. [Methods]Different types of drinking water were randomly sampled within Cangzhou City.Then the fluoride content in the drinking water was detected with fluoride selective electrode. [Results]There were significant differences in fluoride content of drinking water from different sources.The fluoride content in water from self-supply wells and taps in a county was 1.434 9~6.007 9 mg/L,which was higher than the national standard of drinking water.The fluoride content in the tap water of the urban area was 0.589 2 mg/L,which complied with the national standard of drinking water.The fluoride content in water from household faucet filter was 0.484 7mg/L,barreled water for sale 0.023 00~0.040 40 mg/L and mineral water 0.148 2 mg/L. [Conclusion]The fluoride content is different in drinking water from different sources of Cangzhou City,and that in water from self-supply wells and taps in a county exceeds the standards.Further effort should be made to promote the monitoring of the water quality.And measures should be taken to reduce the level of fluoride in water from self-supply wells and taps.Meanwhile,the appropriate level of fluoride should be marked on its labeling.
