Abstract

A cross-sectional survey of the work force at an iron ore surface mine and beneficiation plant in Labrador identified cases with a radiologic diagnosis compatible with simple pneumoconiosis by the International Labour Organization (ILO) classification (1980). Their distribution by ILO categories 1, 2, and 3, after excluding those with confounding diagnoses for pneumoconiosis, was 30, 10, and 2 cases, respectively. ILO category was related to age, duration of current employment, and cumulative respirable dust and quartz levels, as well as to decrement in ventilatory function.

摘要

对拉布拉多一个铁矿石露天矿和选矿厂的劳动力进行的横断面调查，通过国际劳工组织（ILO，1980年）分类法确定了放射学诊断与单纯尘肺相符的病例。在排除那些有尘肺混淆诊断的病例后，按照ILO分类1、2和3类划分，其分布分别为30例、10例和2例。ILO类别与年龄、当前就业时长、累积可吸入粉尘和石英水平以及通气功能下降有关。
