One hundred textile workers were studied for prevalence of byssinosis in Karachi cotton mills.Byssinosis was found to be 8%, along with the prevalence of byssinosis, other respiratory symptoms, changes of ventilatory capacity were studied. Exposure to cotton dust caused significant reduction in FEV1 and FVC in all groups of cotton workers.In byssinotics the reduction of ventilatory capacity was considerably greater in subjects with longer than those with shorter exposure, while in non-byssinotics the response was equal in both groups.Chronic changes of ventilatory capacity developed only in subjects with a longer exposure to cotton dust and were common in the byssinotics.Prevalence of byssinosis was found to be low in spinning department (1 out of 24) or 4.2%, while it was 9% in card rood and 9.4% in low room workers.Although the number of smokers in the card room were similar to that in spinning room, smokers were more prone to byssinosis than non-smokers or ex-smoker.
