一般认为,血镉浓度是近期镉接触最理想的生物学指标。但是,由于镉是一种蓄积性毒物,在人体内的生物半衰期约为20年。因此,在普通人群中,用血镉浓度的高低来反映人体负荷及低浓度近期镉接触的可靠性如何,尚不清楚。本文测定了生活在扎格布拉市区及在同一学校教学或学习的192名教师(男60名、女132名)和52名儿童(男30名、女22名)的 Is generally believed that blood cadmium concentration is the most recent biological indicators of exposure to cadmium. However, since cadmium is an accumulative poison, its biological half-life in humans is about 20 years. Therefore, in the general population, the level of serum cadmium concentration to reflect the human body load and low concentrations of recent exposure to cadmium how the reliability is not clear. This paper measures the total number of 192 teachers (60 males, 132 females) and 52 children (30 males and 22 females) living and studying in the same school in the city of Zagabla
