The lung function status of workers in a cadmium-nickel battery factory was re-examined 3 years after an initial study which showed a mild restrictive effect. During this period, further measures were taken to reduce the cadmium exposure. Of the 44 'original' cadmium-exposed workers, 17 were still exposed to cadmium. Another 13 were transferred to non-cadmium work at least 6 months and 14 left the company at least 1 year before the present study. Blood and urine cadmium concentrations were considerably lower than previously, consistent with the decreased cadmium-in-air levels. The total lung capacity increased both in the workers who were still exposed to cadmium and those who ceased exposure. The latter group also had increased vital capacity and forced expiratory volume in one second. The prevalence of respiratory symptoms decreased particularly in the workers who were no longer exposed to cadmium.
在一项初步研究显示存在轻度限制性影响三年后，对一家镉镍电池厂工人的肺功能状况进行了重新检查。在此期间，采取了进一步措施以减少镉暴露。在最初接触镉的44名工人中，17人仍接触镉。另有13人至少在6个月前被调至非镉作业岗位，14人在本次研究前至少1年离开公司。血液和尿液中的镉浓度比之前大幅降低，这与空气中镉水平的下降一致。仍接触镉的工人以及停止接触镉的工人的肺总量均有所增加。后一组工人的肺活量和一秒用力呼气量也有所增加。呼吸道症状的患病率尤其在不再接触镉的工人中有所下降。
