目的 了解全省地方性氟中毒防治工作的现状。方法 按照《山东省地方性氟中毒防治工作现状调查方案》的要求 ,对全省所有改水降氟工程和改水病村按统一表格进行调查登记。结果 全省共建改水降氟工程 5 934处 ,以打低氟井为主 ;运转基本正常的工程 4 15 9处 ,占 70 0 9% ,不正常的工程 2 6处 ,占 0 4 4 % ,停用报废的工程 174 9处 ,占 2 9 4 7%。全省病区已改水病村 7880个 ,占 6 7 6 0 % ;未改水病村 3776个 ,占 32 4 0 %。已改水病村中 ,有 5 6 89个村的工程运转基本正常 ,占 73 5 4 % ;有 2 110个村的工程运转不正常和停用报废 ,占 2 6 4 6 %。在改水工程运转基本正常的病村中 ,有 4 0 5 0个村的饮水含氟量≤ 1 0 0mg/L ,占改水村的 5 1% ,占全部病村的 35 %。改水实际受益人口 32 4万余人 ,仅占病区总人口的 1/ 3。结论 我省现仍有 76 0 0多个村 ,6 5 5万余人遭受高氟的危害 ,地方性氟中毒防治形势十分严峻 ,须进一步加大防治工作力度。
Objective To understand the status quo of endemic fluorosis in the province. Methods According to the requirements of “Investigation Plan of Local Fluorosis Prevention and Control in Shandong Province”, all the water-reducing and fluoride-reducing projects and water-changing diseases villages in the province were investigated and registered according to a unified form. Results A total of 5 934 projects were set up to reduce fluoride in the whole province, with the main purpose of fighting low-fluoride wells; 4 15 9 projects with normal operations, accounting for 70.9%; 26 projects with abnormal projects accounting for 0 4 4 In total, 174 projects were scrapped, accounting for 294.7%. The province’s ward has changed the number of water-stressed villages to 7880, accounting for 67 76%; 3776 unimpired water-deficient villages have been changed, accounting for 32 40%. Among the villages that have been rehabilitated, 569 projects have basically normalized operations, accounting for 73.5% of the total; 2l10l villages have been operating abnormally and were disused, accounting for 2646%. Among the sick villages where the water diversion works are basically normal, there are 4 0 5 villages whose drinking water fluoride content is less than 1 0 0 mg / L, accounting for 51% of the total, and 35% of the total sick villages. The actual beneficiary population of water diversion is more than 32,400, accounting for only one-third of the total ward population. Conclusion There are still more than 7600 villages in our province, more than 655,000 people suffer from high fluoride. The situation of prevention and control of endemic fluorosis is very serious, so we must further intensify prevention and control efforts.
