Effect of reducing fluoride stove use and five-year dynamic monitoring report
Content; 8 to 12 year-old children the prevalence of dental fluorosis; Ding ~ l2 months each year to monitor and check the sampling of dental fluorosis. 2 results of the monitoring results of dental fluorosis 2,[link widoczny dla zalogowanych],1 in Table 1. Table 1 Monitoring the village children aged 8 to 12, the prevalence of dental fluorosis () Note kuai per year per village, number of monitoring 56 ~ 10522B ~ 12-year-old children in prison halo profile fluorine content results in Table 2. Table 2 Supervisor rob the village children aged 8 to 12 fluorine content in feces (geometric mean) (g / L,[link widoczny dla zalogowanych], Note: Each year the village to teach children in prison _ removed the main 502.3 for the 48 daily average concentration of fluoride in the air monitoring results in Table 3. Table 3 Village residents to monitor daily fluoride content of indoor air (mR / m) injection, with an annual household every five continents without r {2.4 samples per day 3 the amount of food monitoring fluoride boast tame the results in Table 4 . 2,[link widoczny dla zalogowanych],5 stove down to spend monitoring the use of scraping results in Table 5. Wushan County, Sichuan Province, 594,700 units of Health and Epidemic Prevention Station. Chen Hongjun men .43 years old, competent physician. a 99 - Table 4, the mean fluoride content of food monitoring Estate (mg / kg) Note t teach each sample year for each village to village 2o cases monitoring table 5 using the pass rate to reduce fluoride monitoring results stove (6) Note: Supervisor pay per year for each village 25 households. 3 to discuss the use of 3.1 to reduce fluoride stove dental cover to children in former times the relationship between halo is 5 years with the Wu Gorge, the village used to reduce fluoride stove frame rate of Taiwan from 1991 to 1994 remained at between 22 to 28, children's dental fluorosis rate of 79 to 86 of the same, in the urinary fluoride 2.5 ~ 3.9mg / L of smell,[link widoczny dla zalogowanych], no significant improvement in the role of Lang Ping frame rate in Taiwan between 52 ~ 84. the subject of dental fluorosis of children each year in 1991 to 90.2 in 1995 down to 73.4,[link widoczny dla zalogowanych], fluoride content in feces in the l9 ~ 2.9rag fluctuated between children, showing a certain effect, but full compliance rate remains fixed Jianping village in 8o ~ 9O, rate of dental fluorosis endemic in China in 1991, Journal of 16 March 1997 No. 2 gradually decreased to 63.4 in 1995 to 227 (P <0.05). Mean urinary fluoride remain in the normal range (1.0 ~ 1.3mg / L).} infer stoves can be used to reduce fluoride grind against coal-burning endemic fluorosis. the role of size proportional to their use of Ku Taiwan grid. but can come to use the station to maintain frame rate of more than 80 progressive control of endemic fluorosis needs further study occurred in 3.2 Conclusions stove defluoridation the use of air between the amount of fluoride co-Ping Liu, Jianping fluorine content in the air five years, two villages in the 0003 ~ 0.037mg / m fluctuated between, but mostly in the 0.015mg / m below the low level, while the village witch butterfly at a higher level, more than in the 0.065 ~ 0.093mg / m. This stove frame rate is consistent with Taiwan, that the use of qualified low. indoor air with high fluoride content. 3.3 down to win the use of stoves and food the relationship between fluoride levels of total fluoride Jianping village food (corn pepper) from the 1991 high fluoride (4.2,135 mg / kg, reduced to normal levels in 1995 (11,4 rag / kg, the villages of Mindanao Liu Ping Wu volatile fluoride content of food, jade surgery were o8 ~ 4.3,1.3 ~ 96mg/kg, pepper, respectively 20 ~ {2,7 ~ 142rngg. I think this format is used, use the stove to reduce fluoride rate instability about 4.
