摘要
1991年8月对新疆南疆和田、喀什、阿克苏三地区的13个县(市)的部分地区调查表明:所采142份近年来新建水源水样中,有89份含氟量超过国家标准(1mg/L),同地区所采的70份以往饮用水源水样中有13份含氟量超过1mg/L。不同类型水源含氟量比较以浅层地下水超标比例最高为89.7％(35/39),深层地下水次之为52.4％(54/103),地表水最低为18.5％(13/70)。儿童尿氟均值随其所饮用水源含氟量升高而升高。由于使用新水源时间长短不同,水氟超标水源周围人群的氟中毒病情高低不同,个别饮用高氟水时间较长地区已出现严重的儿童和成人氟中毒流行。南疆特殊的自然、地理、气侯及民族生活习惯等诸因素都对氟中毒流行产生一定影响,近年南疆新建水源很多,其含氟量升高的后果令人担忧。
An investigation which carried out in some part of 13 counties (or cities )in the 3 prefectures of Hotan, Kaxgar and Aksu in south Xinjiang in August 1991, showed that of the 142 water samples collected from the newly built water sources, 89(62.7%) samples had fluoride level exceeding 1mg/ L, whereas in 13(18.5%) out of 70 smples collected from previous using drinking water sources in the same place did the water fluoride content exceed 1mg/L. The shallow ground water had the highest rate of fluoride content exceeding 1mg/L(89.7%)followed in turn by deep ground water (52.4%) and surface water (18.5%). The mean urinary fluoride level of children increased with the elevation of drinking water fluoride level. The dental fluorosis rates of children in the vicinity of these water sources with fluoride level exceeding 1mg/ L were different for the use of the water supplies differed in length. In individual areas where high fluoride level water supplies had been used for longer period was observed harmfulness in the form of severe fluorosis in children and adults. There have been many newly built drinking water sources in the south of Xinjiang in recent years, since the natural condition, climate, geographical feature and some customs of the minority inhabitant etc., in the south of Xinjiang can aggravate the condition of fluorosis, we are warned about the possible disastrous consequences in the future.
