[目的]为查清拟建工程周边人群地方性氟中毒患病与流行情况。[方法]2010年1月对民和县拟建某电解铝厂周边人群(儿童与成人比较)进行与氟相关的健康危害因素基线调查。儿童氟斑牙诊断采用Dean氏法。儿童尿氟含量,饮用水氟含量均采用氟离子选择电极法测定。粮食和蔬菜氟含量测定用加热-酸浸-电极法测定。[结果]拟建某电解铝厂周围人群饮用水、粮食、蔬菜氟化物含量均在国家规定的最高限值内,分别为:0.21 mg/L、1.17 mg/kg、0.08 mg/kg;44名儿童与61名成人的尿氟未超过国家卫生标准正常值;45名儿童与60名成人中未检出氟斑牙。[结论]当地人群中未检出氟斑牙,拟建电解铝厂周围环境无氟化物污染。
[Objective] To find out the prevalence and prevalence of endemic fluorosis in peripheral population of the proposed project. [Method] In January 2010, a baseline survey of health risk factors related to fluoride was conducted in Minhe County, a population surrounding the proposed aluminum smelter in Minhe County (comparison between children and adults). Diagnosis of children’s dental fluorosis using Dean’s method. Urine fluoride content in children, drinking water fluoride content were determined by fluoride ion selective electrode method. Determination of fluorine content in food and vegetables by heat - acid leaching - electrode method. [Result] The fluoride content of drinking water, foodstuff and vegetables in the surroundings of the proposed aluminum smelter were all within the national maximum limits of 0.21 mg / L, 1.17 mg / kg and 0.08 mg / kg respectively. 44 Urinary fluoride in children and 61 adults did not exceed the normal national health standards; dental fluorosis was not detected in 45 children and 60 adults. [Conclusion] The dental fluorosis was not detected in the local population, and the environment around the proposed aluminum smelter was free of fluoride pollution.
