采用原子吸收分光光度法测定了106名7～14岁农村儿童头发中氟、锌、铜、铁、镁的含量,其中高氟区50名(男24,女26);对照区56名(男25,女31)。分析结果显示:高氟区儿童发氟明显高于对照区(P<0.05)发铜、镁则低于对照区(P<0.01)。在同一地区,发氟随年龄增长而升高;发中铜、镁、铁、氟的含量有性别间差异,均为女性高于男性(P<0.05);锌与铁呈负相关,镁分别与锌、铜、铁呈正相关(P<0.05)。
The contents of fluorine, zinc, copper, iron and magnesium in hair of 106 rural children aged 7-14 years were determined by atomic absorption spectrophotometry. Among them, 50 were high fluoride (male 24, female 26) and 56 were male 25, female 31). The results showed that the incidence of fluoride in children with high fluoride was significantly higher than that in the control (P <0.05), but lower in the control group (P <0.01). In the same area, the content of fluoride increased with age. The content of copper, magnesium, iron and fluoride in the hair had gender differences, both were higher in female than in male (P <0.05) And zinc, copper, iron was positively correlated (P <0.05).
