Four hundred and eighty-six textile workers in three cotton mills and one wool/synthetic mill were studied for symptoms and functional effects of workroom exposure to dust. Byssinosis was found in 5.7% of 386 cotton workers, with an apparent threshold level of 0.5 mg cotton dust/m3 of air. Mean post-shift functional declines were greater in workers exposed to greater than or equal to 0.2 mg/m3....

This paper is of some historical interest. It describes an investigation to determine whether byssinosis occurred among workers in the waste cotton industry. It was undertaken in 1950 at the instigation of the Minister of National Insurance. The materials used in the industry were (i) cotton that had been previously spun, and (2) waste material discarded during the preparations for spinning hig...

Epidemiological investigation of 475 workers exposed to dust in flax processing has shown that family susceptibility has a decisive role in the development of byssinosis in those workers. Workers whose fathers had occupational history of exposure to flax dust were more resistant to the development of the disease than those whose fathers had no such history. Such tolerance was much higher in wor...

There has been no report of byssinosis in Hong Kong although the textile industry has been one of the leading industries for many years. Three workers with a long history of exposure to cotton dust had chronic obstructive airways disease precipitated by their work environment. One had irreversible airways obstruction but none had chronic bronchitis, emphysema, or asthma. Only one gave a history...

The changes in symptoms and lung function tests of 26 cotton cardroom workers were investigated before and after inhalation of histamine aerosols. Three subjects with no chest symptoms and ii with uncomplicated byssinosis showed no evidence of any pulmonary reaction, but I2 bronchitic byssinotic subjects showed evidence of the pulmonary hypersensitivity found in patients with chronic bronchitis...

Some of the workers in the dustier parts of a cotton mill (cardand blow-rooms) develop byssinosis. They experience tightness of the chest and breathlessness on Mondays or on the first day at work after an absence; these symptoms come on gradually, reaching a peak during the afternoon or early evening. In the early stages (Grade I) the workers feel quite fit by the next day; in the more severely...
