研究了1943-1973年间在美国田纳西州橡树岭的3个工厂工作的1059名白色男性焊工的死亡率和死亡原因。根据截至1974年报告的死亡，所有原因的标准化死亡率（SMR）为87（观察到173例死亡，而根据美国白色男性的死亡率预期为199例）。没有鼻窦癌导致的死亡，肺癌的SMR为150（95%置信限= 87和240）。在橡树岭气体扩散（K-25）工厂，这些焊工中的一个小组（536人）暴露于NiO;最近的空气中Ni浓度（来自个人空气采样器）高于拟定标准。K-25工厂焊工肺癌和呼吸系统疾病的标准化死亡率并不高于其他焊工（523）。雇用的焊工基于少量死亡（观察到5例vs.预期2.66例），K-25工厂50周的肺癌SMR为188（95%置信限= 61和438）。需要对这些群体采取进一步的后续行动。
Mortality and causes of death were examined among 1059 white male welders employed between 1943-1973 at 3 plants in Oak Ridge, Tennessee [USA]. Based on deaths reported as of 1974, the standardized mortality ratio (SMR) for all causes was 87 (173 deaths observed vs. 199 expected on the basis of death rates for USA white males). There were no deaths resulting from sinonasal cancer and the SMR for lung cancer was 150 (95% confidence limits = 87 and 240). A subgroup of these welders (536) was exposed to NiO at the Oak Ridge Gaseous Diffusion (K-25) Plant; recent air concentrations of Ni (from personal air samplers) were greater than proposed standards. Standardized mortality ratios for lung cancer and diseases of the respiratory system were not higher among K-25 Plant welders than among other welders (523). Welders employed for .gtoreq. 50 wk at the K-25 Plant had an SMR for lung cancer of 188 (95% confidence limits = 61 and 438) based on small numbers of deaths (5 observed vs. 2.66 expected). Further follow-up of these groups is needed.
