In the course of a study on the health effects of vermiculite, 653 black rural industrial workers had their lung function measured. Since the study revealed no health effects of their industrial environment, the group was used to determine prediction equations for black men. Vital capacity, forced vital capacity, forced expiratory volume in 1 second, and peak flow were appreciably higher than the predicted values for blacks in the USA. The predicted values were, however, lower than those reported for white non-smokers but significantly higher than those reported for a non-smoking group of black miners in South West Africa/Namibia.
在一项关于蛭石对健康影响的研究过程中，对653名黑人农村产业工人进行了肺功能测量。由于该研究未发现其工业环境对健康有影响，因此该组被用于确定黑人男性的预测方程。肺活量、用力肺活量、1秒用力呼气量和峰值流量明显高于美国黑人的预测值。然而，这些预测值低于非吸烟白人报告的值，但明显高于西南非洲/纳米比亚一组非吸烟黑人矿工报告的值。
