Lung diseases in farmers attributable to their occupation include (a) farmer's lung, caused by exposure to mouldy hay, (b) the asthma caused by exposure to grain dust and (c) silo-filler's disease. Their prevalence in Canada is unknown. Farmer's lung results from inhalation of mould spores in hay; the mechanism is immunologic. The exact cause and mechanism of grain dust asthma are unknown but may be immunologic. Silo-filler's disease is caused by the toxic effects of inhaled nitrogen dioxide.
(a)因接触发霉干草引起的农民肺;(b)因接触谷物粉尘引起的哮喘;(c)谷仓装料工病。它们在加拿大的患病率尚不清楚。农民肺是由吸入干草中的霉菌孢子所致,其发病机制为免疫性。谷物粉尘哮喘的确切病因和机制尚不清楚,但可能是免疫性的。谷仓装料工病是由吸入二氧化氮的毒性作用引起的。
