摘要
目的进一步明确乌苏市高砷、高氟区分布范围,为防治工作提供科学依据。方法对已确定和可疑的高砷、高氟区进行拉网式筛查,测定饮水砷、氟水平。结果采集的1069份压井和机井水样中,水砷超标率58.56%,水氟超标率41.12%,不同乡镇水砷、水氟超标率差异有统计学意义(χ2=739.58、384.72,P<0.001),不同井深水砷、水氟超标率差异也有统计学意义(χ2=790.89、384.72,P<0.001)。结论调查地区水氟、水砷超标情况十分严重;不同乡镇水砷、水氟差异较大,且有在同一乡(镇)、村不同井水含砷、氟差异大,高砷、高氟水点呈点状或片状分布的特点;水砷、水氟可能与井深有关;应加强高砷、高氟水区地方性氟中毒、砷中毒防病知识健康教育工作。
Objective To deepen the depth and widen the range of the surveillance on the distribution of high arsenic and high fluoride in Wusu City thus to provide scientific basis for prevention. Methods In confirmed and suspected area of high arsenic.and high fluoride, screening survey was carried out, and the levels of arsenic and fluoride in the water were determined. Results Amongth 1 069 water samples collected from manual wells and mechanized wells, 58.56% exceeded the criteria for arsenic and 41.12% for flouride. There were significant differences of the rates of water arsenic and fluoride going beyond the criteria among different villages and towns （X^2 = 739.58,384.72, P 〈 0.001 ） and among the water samples from different depth of wells （X^2 = 790.89,384.72, P 〈 0.001）. Conclusions The over-criterion water arsenic and water fluoride prevails seriously;there are differences of levels of the water arsenic and fluoride in different villages and towns as well as in the different wells in the same village and town; high arsenic and high fluoride distribute in spots or patches.
