近些年来,许多研究已指出,可使用发铅含量做为铅的职业接触指标,现代分析技术已能够测定在头发中的金属含量。这一试验对接触铅工人单根头中铅含量与血铅含量进行测定,以指示两者之间的关系。分别测定接触不同铅浓度男性工人发铅和血铅。第一组31人,接触空气中铅浓度较高。第二组33人,接触低浓度铅。对照组的10人从未接触过铅。
In recent years, many studies have pointed out that the lead content of lead can be used as an occupational exposure indicator, and modern analytical techniques have been able to determine the metal content in the hair. This test measures lead levels and blood lead levels in exposed heads of lead workers to indicate the relationship between the two. Male workers exposed to different lead concentrations were tested for lead and blood lead respectively. The first group of 31 people, exposed to high concentrations of lead in the air. The second group of 33 people, exposed to low concentrations of lead. Ten people in the control group had never been exposed to lead.
