摘要
探讨了空气中不同浓度铅对作业工人健康的影响.选择本地区不同铅浓度的两个厂矿的177名接触铅工人为调查对象,并以不接触铅而其它条件相同的行政人员为对照组.对接触不同浓度铅和对照组的人员作全面查体并结合实验室作有关生物指标检测.结果表明,接触较高铅浓度的某蓄电池厂98名工人,受铅职业危害较严重,检出慢性铅中毒14人（占14.2％）,铅吸收10人（占10.2％）,且发生症状和体征之阳性率亦比铅锌矿和对照组明显高（P＜0.05）,而低浓度铅的铅锌矿与对照组则未见明显区别（P＞0.05）.空气中铅浓度高低对接触者健康影响成剂量-反应关系.
The health of workers exposed to air lead of different content was studied from two industrial enterprises (one was an accumulator factory, air lead content: highest to 2 .7 mg/m3, average 0.649 mg/m3; the other one was a lead-zine mine, air lead content: highest to 0. 75 mg/m3, average 0. 048 mg/m3) and the cadres non-exposed to any air lead were taken as controls. The health of 98 workers exposed to the higher content air lead for the accumulator factory was damaged severer. Fourteen of them were diagnosed as chronic lead poisoning (14.2%) and ten of them as lead absorbing (10.2%). The rate of clinical symptoms was also higher than that from the lead-zine mine and the controls (P < 0.05). The health difference between the workers exposed to the low air lead and the controls were not significant (P>0.05). The relationship of dose-effectiveness exists between the contactors health and the conten of air lead.
