Investigation and Analysis on Current Situation of Coal-Burning Fluorosis Prevalence
Abstract: Objective: The purpose of the paper is to provide the result from investigation on the current situation of coal-burning fluorosis prevalence in Chongqing City and make an assessment on the prevention and curing measures. Method: The Dean’s Method is applied to investigate on the fluorotic teeth of locally-born children aged between 8 to 12; investigate how modified cooking stoves are utilized by households and how food maize and hot pepper are being dried; and test the urinary fluorine content and pepper fluorine content. Result: The investigations show that, in the 661 villages with illness history from the 100 townships of 13 districts in Chongqing City, 11.28% (7464/ 66,162) of the children aged between 8 and 12 suffer from dental fluorosis; the stoves modified rate, qualified rate of modified stoves, and correct utilization rate of qualified modified stoves are respectively 100%, 98.82%, and 99.45%; and food maize and hot pepper’s drying rates are respectively 99.88% and 99.75%. Conclusion: The result shows that the coal-burning type fluorosis prevalence in the endemic area of Chongqing City has decreased dramatically, the preventive measure is effectively implemented, and a long-term preventive mechanism has preliminarily been established.
