目的了解职业卫生达标环境铅作业人员血铅(PbB)和血锌原卟啉(ZPP)的变化。方法选择金华市某蓄电池厂149名铅作业人员为研究对象,用火焰原子吸收光谱法测定空气中铅烟和铅尘的浓度,用石墨炉原子吸收光谱法测定PbB的浓度,用ZPP-3800型血液锌卟啉仪测定ZPP的浓度。结果经蓄电池行业整治后该生产车间岗位铅烟、铅尘的超标率为0,149名铅作业人员的PbB浓度为53μg/L~593μg/L,超标19人,超标率为12.8%;ZPP浓度为0.09μmol/L~9.95μmol/L,超标36人,超标率为24.2%。女性工人的PbB和ZPP超标率>男性工人。不同工龄铅作业工人的PbB和ZPP超标率差异无统计学意义。男性铅作业工人的PbB浓度和ZPP浓度有相关性,而女性工人无相关性。结论职业卫生达标环境铅作业人员的健康监护也不容忽视,建议对铅作业工人开展PbB和ZPP的联合检测。
Objective To understand the changes of blood lead (PbB) and zinc protoporphyrin (ZPP) in lead workers in occupational health standards. Methods 149 lead workers in a battery factory of Jinhua City were selected as the research objects. The concentrations of lead and lead dust in the air were determined by flame atomic absorption spectrometry. The concentration of PbB in the air was determined by graphite furnace atomic absorption spectrometry. Blood zinc porphyrin instrument for the determination of the concentration of ZPP. Results The over-standard rate of lead smoke and lead dust in the post-production workshop was 0,149 lead workers. The PbB concentration was 53μg / L ~ 593μg / L, exceeding the standard of 19 by 12.8%. The ZPP concentration was 0.09 μmol / L ~ 9.95μmol / L, exceeding the standard of 36, exceeding the rate of 24.2%. Female workers PbB and ZPP exceeded the rate of> male workers. There was no significant difference in PbB and ZPP over-standard rates for lead workers of different ages. There is a correlation between PbB concentration and ZPP concentration in male lead workers, but no correlation in female workers. Conclusion The health care of lead workers in occupational health standard environment should not be neglected. It is suggested that PbB and ZPP should be jointly tested by lead workers.
