目的了解蓄电池行业铅危害状况和工人尿铅水平。方法车间空气铅烟、铅尘采用火焰原子吸收光谱法进行测定,工人尿铅水平采用“尿中铅的双硫腙法”进行测定。结果车间各部位空气中铅浓度均有不同程度的超标,最高超过国家标准的25倍;272名工人尿铅超标(≥0.07mg/L)人数121人,超标率44.49%,接铅工人尿铅超标率(46.91%)高于行管后勤人员(24.14%)(P<0.05)。结论蓄电池行业铅危害严重,应加强监督管理,预防和控制职业性铅中毒病例的发生。
Objective To understand the lead hazard in the battery industry and the level of urinary lead in workers. Methods The air lead smoke and lead dust in the workshop were determined by flame atomic absorption spectrometry. The level of urinary lead in workers was measured by the method of “Dithizone method of urinary lead”. Results The lead concentration in air of various parts of the workshop exceeded the standard in different degrees, up to 25 times higher than the national standard. The number of 121 workers with excess lead (≥0.07 mg / L) in 121 workers exceeded the standard by 44.49% The rate of exceeding the standard (46.91%) was higher than that of the administrative staff (24.14%) (P <0.05). Conclusion The lead in the battery industry is seriously endangered. Supervision and management should be strengthened to prevent and control the occurrence of occupational lead poisoning cases.
