1988年选长沙市某瓷厂幼儿同3～6岁幼儿109钙(男52,女57人),在枕部剪1.0克头发,用ICPSS—V型中阶梯光栅光电直读仪测定。本研究结果表明,幼儿发镉随年龄增加而直接增加,发锌则相反。按血红蛋白<10克分组时,则发镉和发锌异常(高)检出率均显著高于血红蛋白≥11克组(P<0.05)。按发镉是否超过0.045ppm(正常值上限)将幼儿分两组,则发锌值显著有差别(P<0.05),
In 1988, a porcelain factory in Changsha City, Changsha, with 3 to 6-year-old children 109 calcium (52 males and 57 females), cut in the occipital hair 1.0 grams, with ICPSS-V-type ladder grating photoelectric direct reading instrument measured. The results of this study show that cadmium cadmium directly increases with age, hair zinc is the opposite. When hemoglobin was less than 10g, the detection rates of abnormalities of cadmium and zinc were significantly higher than those of hemoglobin≥11g (P <0.05). According to hair cadmium is more than 0.045ppm (upper limit of normal) will be divided into two groups of children, the hair zinc value was significantly different (P <0.05)
