For many years there has been much argument whether workers in the dusty trades are prone to chronic bronchitis. In 1966 the Medical Research Council issued a report of a Select Committee which concluded that occupationally induced bronchitis did not play a significant part in the aetiology of airways obstruction in dust-exposed men. Since then epidemiological studies have demonstrated that the prolonged inhalation of dust leads to an increase in prevalence of cough and sputum. Furthermore, new physiological techniques have demonstrated a slight decrement in ventilatory capacity as a result of industrial bronchitis, and which is related to lifetime dust exposure. Unlike bronchitis induced by cigarette smoke, the predominant effect of industrial bronchitis is on large rather than small airways and the condition is not accompanied by emphysema.
多年来，对于从事粉尘作业的工人是否易患慢性支气管炎一直存在诸多争论。1966年，医学研究理事会发布了一份特别委员会的报告，该报告得出结论，职业性诱发的支气管炎在接触粉尘男性的气道阻塞病因中并不起重要作用。从那时起，流行病学研究表明，长期吸入粉尘会导致咳嗽和咳痰的患病率增加。此外，新的生理学技术已证明，由于工业性支气管炎，通气能力会略有下降，且这与终生接触粉尘有关。与香烟烟雾诱发的支气管炎不同，工业性支气管炎的主要影响在于大气道而非小气道，且该病症不会伴有肺气肿。
