Lungs taken at autopsy from 100 urban residents were studied to determine concentrations of 21 trace metals, dust, free silica and hydroxyproline. Medical, occupational and environmental histories were collected so that correlation studies might be done. The potential value of this data as a baseline for further studies of occupationally diseased lung tissue was assessed by evaluating the results of an analysis of variance. The personal histories were used as the criteria for classifying the observations (lung concentrations) into groups for the statistical analysis.
对从100名城市居民尸检中获取的肺部组织进行研究，以测定21种痕量金属、灰尘、游离二氧化硅和羟脯氨酸的浓度。收集了医疗、职业和环境史，以便进行相关性研究。通过评估方差分析结果，评估了这些数据作为进一步研究职业性病变肺组织基线的潜在价值。个人史被用作将观察结果（肺部浓度）分类为不同组以进行统计分析的标准。
