摘要
目的了解2005年山东省济宁市地方性氟中毒(简称地氟病)病区的水氟分布和改水降氟工程的现状。方法在济宁市选择有地氟病的任城区、梁山县和嘉祥县进行饮用水氟筛查和改水降氟工程运行情况调查,采用氟离子选择性电极法测定水氟。结果共筛查了671个村.饮水含氟量≤1.00mg/L的村为170个(占25.34%),〉1.00mg/L的村为501个(占74.66%),水氟最高为11.33mg/L。共检测改水降氟工程497处,其中报废工程161处(占32.39%),正常运行工程334处(占67.20%),间歇运行工程2处(占0.40%)。正常和间歇运行的336处改水降氟工程,饮水含氟量≤1.00mg/L的工程为281处(占73.18%),〉1.00mg/L的工程为55处(占26.82%),最高为4.28mg/L。结论济宁市地氟病防治形势仍然十分严峻,须尽快落实防治措施和加强改水降氟工程的监测和管理工作。
Objective To investigate water fluoride content and the current status of water-improving project in Jining, Shandong Province in 2005. Methods Water fluoride content and the status of water-improving project were investigated in Rencheng Ditrict, Liangshan and Jiaxiang Couties of Jining City. The fluoride content in drinking water was assessed by F-ion selective electrode. Results Water fluoride contents of 671 fluorosis villages were determined. One hundred and seventy villages had water fluoride content less than or equal to 1.00 mg/L (accounting for 25.34% ) and 501 villages water fluoride content higher that 1.00 mg/L (accounting for 74.66%), with the highest being 11.33 mg/L. Four hundred and ninty-seven projects were surveyed, in which 16l projects were discarded (accounting for 32.39%), 334 projects worked well(accounting for 67.20%), and 2 projects worked fitfully (accounting 0.40% ). Two hundreds and eighty-one projects had water fluoride content ≤ 1.00 mg/L and 55 projects had water fluoride content 〉 1.00 mg/L(accounting for 26.82%), with the highest being 4.28 mg/L. Conclusions The situation of endemic fluorosis control is still serious in Jining City. Countermeasures for endemic fluorosis must be carried out as soon as possible and surveillance of water-improving and defluoridation projects must be strengthend.
