Passage 3

Topic

饮用水中是否含氟FLUORIDATION

FLUORIDATION OF PUBLIC WATER SUPPLIES

Water fluoridation is the process of releasing small amounts of fluoride into the public water

supply as a way to reduce dental health problems. The process of reducing tooth decay

through fluoridation is clearly understood, and research confirms water fuoridation's effect

on limiting instances of tooth decay. Nevertheless, fluonide is not harmless in all quantities.

At levels moderately above those desired, it can result in something known as floozies, and

at very high levels acute fluoride poisoning can occur.
