为探讨微量元素与儿童某些疾病的关系,需确定本地区童发中微量元素正常值范围。检测了415名儿童发样,结果:据根对数正态分布,童发铜含量均值为13.52μg/g,发铅、发镉用百分位数法求正常值95%上限,Pb:男9.679μg/g,女14.878μg/g,Cd:男0.382μg/g,女0.18μg/g。Cu-Pb,Cu-Cd,Pb-Cd含量均高度正相关。
In order to explore the relationship between trace elements and some diseases in children, we need to determine the normal range of trace elements in children’s hair in this area. 415 children were tested for hair samples. Results: Based on the root logarithmic normal distribution, the average copper content in children hair was 13.52 μg / g. The upper limit of 95% of the normal value was found for lead and cadmium by the percentile method. Pb: Male 9.679 μg / g, female 14.878 μg / g, Cd: male 0.382 μg / g, female 0.18 μg / g. Cu-Pb, Cu-Cd, Pb-Cd content were highly correlated.
