Kapok is a cotton-like fibre obtained from the fruits of Ceiba pentandra, a tree surgeon in tropical countries. In Sri Lanka ginning of kapok is usually done by machine in poorly ventilated buildings where workers are exposed to a great deal of dust. Forty-one workers in five ginneries in Colombo were examined. Mill fever occurred in 28 (77-8%) of the 36 workers who were able to give a history. Chronic bronchitis, which is an uncommon condition in Sri Lanka, was detected to seven workers with an average of 20-9 years' service in the industry. It is suggested that chronic bronchitis is an occupational hazard of workers who are exposed to kapok dust for long periods. Byssinosis was not found in any of the workers studied.
木棉是一种类似棉花的纤维，取自热带国家的吉贝树（Ceiba pentandra）的果实。在斯里兰卡，木棉通常在通风不良的建筑物中由机器进行轧花，工人会接触到大量灰尘。对科伦坡五家轧棉厂的41名工人进行了检查。在能够提供病史的36名工人中，有28人（77.8%）出现了棉尘病热。慢性支气管炎在斯里兰卡并不常见，在7名从事该行业平均20.9年的工人中被检测到。有人认为，慢性支气管炎是长期接触木棉粉尘的工人的一种职业危害。在所研究的工人中未发现棉屑沉着病。
