(·上海春招)A 69­year­old grandmother with  no teeth of her own has eventually won a long legal  battle to stop a Scottish regional council(政務(wù)委員會) adding fluoride(氟化物)chemical to the public water  supply.

In a case which has already cost the taxpayer ￡1,000,000，the judge ruled that it was beyond the powers of the local authority to add the chemical to the water in order to reduce tooth decay.

At her home last night Mrs Catherine McColl said, “I did what I thought was right and I would do it again，too.”She claimed that adding fluoride to public drinking water made it into some kind of dirty soup.“Where would it stop？”she asked.“They might come up with the idea of putting drugs into the water to keep the unemployed quiet.”It was a horrible poison，she said，that could have caused all kinds of diseases，including cancer.

The judge, however, concluded that there was no evidence  to suggest that the inclusion of fluoride in the water supply would have had a negative effect on public health. Although the chemical might serve as an efficient and convenient means of achieving a beneficial effect on  the dental health of consumers generally, he said, and its  use was greatly favoured by the dental profession, he  could also understand why some members of the public, Mrs McColl in particular，might be passionately opposed  to the action of the Water Authority in assuming the  right to improve public well­being without consulting the public in the first case. The Authority's legal duty to provide“wholesome” water for public consumption which was both safe and pleasant to drink，did not，he said，extend to their right to safeguard public health by chemical means.
