The environment and health of a working population exposed simultaneously to jute and hemp were studied. Classical symptoms of byssinosis were not present but 21 workers (7%) complained of atypical tightness of the chest. The prevalence of chronic bronchitis among the exposed workers was statistically significant in comparison with controls. Effects of dust concentrations, age and duration of exposure on the prevalence of chronic bronchitis were studied. A statistically significant reduction in FEV1.0 at the end of a work shift occurred in all the exposed workers. Bronchodilators given after the shift showed that acute reductions in forced expiratory volumes were nearly fully reversible in all exposed workers. Smokers and those with chronic bronchitis had greater reductions in FEV1.0 values at the end of the work shift.
对同时接触黄麻和大麻的在职人群的环境与健康状况进行了研究。棉尘病的典型症状并不存在，但有21名工人（7%）主诉胸部有非典型的紧绷感。与对照组相比，接触工人中慢性支气管炎的患病率具有统计学意义。研究了粉尘浓度、年龄和接触时长对慢性支气管炎患病率的影响。所有接触工人在一个工作班次结束时FEV1.0均出现具有统计学意义的下降。班次结束后给予支气管扩张剂显示，所有接触工人用力呼气量的急性下降几乎完全可逆。吸烟者和患有慢性支气管炎的工人在工作班次结束时FEV1.0值下降幅度更大。
