[目的 ]了解铅烟对钢铁冶炼工人血压的影响。 [方法 ]定期监测车间空气中铅烟浓度 ,对作业工人测定血铅及血压 ,并与对照组比较。 [结果 ]调查组低血铅检出率明显高于对照组 ,血铅含量和高血压、低血压之间未发现平行关系。 [结论 ]铅作业工人存在明显低血压危害。 [Objective] To understand the influence of lead smoke on the blood pressure of steel-smelting workers. [Methods] The concentration of lead smoke in the air of the workshop was monitored regularly. The blood lead and blood pressure of workers were measured and compared with the control group. [Results] The detection rate of low blood lead in the investigation group was significantly higher than that in the control group. There was no parallel relationship between blood lead level, hypertension and hypotension. [Conclusion] Lead workers have obvious hypotension.
