镉是一种机体非必需元素,体内积蓄超过临界量时会导致慢性中毒。本文探讨慢性镉中毒亚临床诊断指标研究的进展。Ghezzi I,等调查83名长期接触镉烟男工的血镉、尿β_2—微球蛋白、24小时尿和现场镉含量。现时接触量和累积性接触量(现场镉浓度乘接触持续时间)较高的工人,血镉量明显增高,但受接触持续时间影响较少。累积性接触量较高的工人,尿镉量明显增高,但较少受现时接触量的影响。就群体而言,血
Cadmium is a non-essential element of the body, the body will accumulate more than the critical amount will lead to chronic poisoning. This article explores the progress of subclinical diagnosis of chronic cadmium poisoning. Ghezzi I, et al investigated the blood cadmium, urinary beta 2-microglobulin, 24-hour urinary and on-site cadmium levels in 83 long-term exposed workers. At present, workers with a higher level of exposure and cumulative exposure (on-site cadmium concentration by contact duration) have a significantly higher blood level of cadmium, but are less affected by the duration of exposure. Workers with higher cumulative exposure had significantly higher urinary cadmium levels, but were less affected by the current level of exposure. In terms of the group, blood
