The presence of ferruginous bodies (FB) at 90 autopsy cases were analysed. The cases belong to 1975, 1982 and 1988. Two grams of lung was digested and observed the following results: 4.2 FB/g in 1975, 17.0 FB/g in 1982 and 42.5 FB/g in 1988. Males, Mexico City dowlers, smokers and carcinoma bronchogenic group were exposed to higher FB. The correlation between employment and FB was observed. Three parameters of FB concentration: 0-100 environmental exposure, 100.1-1,000 environmental and occupational exposures, and more 1,000 to occupational exposure was observed. The asbestos core was predominant in all FB analysed. No correlation between age and FB was observed. Finally there is a nonoccupational exposure to asbestos fibres in our environment.
对90例尸检病例中含铁小体（FB）的存在情况进行了分析。这些病例来自1975年、1982年和1988年。取2克肺组织进行消化处理，观察到以下结果：1975年为4.2个FB/克，1982年为17.0个FB/克，1988年为42.5个FB/克。男性、墨西哥城居民、吸烟者和支气管癌组接触到的FB含量更高。观察到职业与FB之间的相关性。观察到FB浓度的三个参数：0 - 100为环境暴露，100.1 - 1000为环境和职业暴露，超过1000为职业暴露。在所有分析的FB中，石棉核心占主导地位。未观察到年龄与FB之间的相关性。最后，在我们的环境中存在对石棉纤维的非职业性暴露。
