镉不是人体必须的元素,但镉广泛存在于人们生活环境之中。为了正确评价环境镉污染对健康的影响,常需知道非职业接触人群镉的暴露水平,血镉浓度是反映近期暴露水平的良好指标.因此,我们测定了非职业接触人群血镉水平,为环境现状提供科学依据。方法、材料、结果我们在南宁市26所中学中随机抽取10所中学的240名教师(男122、女118),以一定浓度硝酸液处理过的玻璃注射器,尼龙座针头抽取静脉血4 ml,EDTANa_2抗凝,按“用基体改进剂无焰原子吸收光谱直接测定全血中镉和铅”的方
Cadmium is not an essential element of the human body, but cadmium is widely present in people’s living environment. In order to properly evaluate the health effects of cadmium pollution in the environment, it is often necessary to know the level of cadmium exposure in non-occupational exposure groups, and blood cadmium concentration is a good indicator of recent exposure levels. Therefore, we measured the level of serum cadmium in non-occupational exposure groups, The status quo provides a scientific basis. Methods, Materials, Results We randomly selected 240 teachers (122 men and 118 women) from 10 middle schools in 26 middle schools in Nanning City. Venous blood was drawn from the needle of a nylon seat using a glass syringe treated with nitric acid solution at a certain concentration.
