发铅作为铅接触指标的研究,近年来国内外已有不少报导。有人认为发铅和铅中毒的临床症状及其生化指标密切相关,可作为急性铅中毒的诊断指标。一般认为:铅作业工人头发含铅量较高;大气污染严重的城市,居民的发铅量也相对较高;所以可用发铅作为估价环境对人作用的指标之一。更有人强调指出,由于发铅受到年龄、性别、居住地区、饮食等因素的影响,在使用发铅这一指标时,必须参照当地相同的性别和年龄组的正常值。本文的目的在于了解南宁铁路地区一般人群发铅的正常值,并探讨它和年龄、性别的关系。

Some people think that lead and lead poisoning clinical symptoms and biochemical indicators are closely related, can be used as a diagnostic indicator of acute lead poisoning. It is generally believed that lead workers have higher levels of lead in their hair. In cities with severe air pollution, residents also have a relatively high level of lead in their hair. Therefore, lead can be used as an indicator of the role of the environment in valuing the environment. It was further emphasized that due to age, sex, place of residence, diet and other factors, hair lead should be referenced to the same local gender and age group as normal. The purpose of this paper is to find out the normal value of lead in the general population in Nanning railway and to explore its relationship with age and gender.
