钒是稀有金属,广泛存在于自然界。1830年Sefstrom提纯钒元素后,钒即受到各方面的重视。大气中钒主要从呼吸道侵入人体,分布于骨和肾,并主要通过肾脏排出体外。据报导,侵入人体的钒在第一个24小时内能从肾脏排除大约61％,故研究钒对人体的影响可以用尿钒含量作指标。 我们于1983年6月对攀钢生活区的儿童进行了尿钒含量测定,以探索大气钒污染与儿童尿钒的关系。
Vanadium is a rare metal, widely found in nature. After the Sefstrom purification of vanadium in 1830, vanadium is valued by all parties. Vanadium in the atmosphere mainly invades the human body from the respiratory tract, distributes in the bones and kidneys, and excretes mainly through the kidneys. It has been reported that vanadium invaded the human body can exclude about 61% of the kidneys in the first 24 hours. Therefore, the study on the effect of vanadium on the human body can use the urinary vanadium content as an indicator. In June 1983, we measured urinary vanadium levels in children living in Panzhihua Iron and Steel Group to explore the relationship between atmospheric vanadium pollution and urinary vanadium in children.
