【Abstract】 [Objective]To understand the spread and distribution of the local fluorosis in Zhengzhou,and the progressing,running and scrapping situation of Water Improvement and Fluoride Reduction Project.[Methods]Fluoride Water was determined by Fluoride-ion electrode method.Fluoride speckle tooth were examined according to Dean.[Results]According to this general investigation upon fluorosis,it was confirmed that 258 natural villages were still suffering from fluorosis of drinking water type at present.The project was carried out in 464 different places from 1982 to the end of 2004,which benefited 671 natural villages and 311 118 people.The project was running well in 434 places(93.5%)and scrapped in 30 places(6.5%).[Conclusion] Based on the investigation,we clarify the current spread and distribution of the local fluorosis as well as the state of progressing,running and scrapping in the Water Improvement and Fluoride Reduction Project before 2004,which provides scientific basis for preventing and controlling of local fluorosis in long-term.更多还原
