Pharmacological prevention of acute ventilatory capacity reduction in flax dust exposure

Pharmacological prevention of acute ventilatory capacity reduction in flax dust exposure.

Ventilatory capacity changes on exposure to cotton dust.

The same plan of investigation as was used in a previous study of jute workers (Gandevia and Milne, 1965) has been applied to a survey of 50 workers in the blowroom and carding and spinning area of a Sydney cotton mill. Significant decreases in ventilatory capacity were recorded on Friday, Monday, and the following Thursday, with, on the average, complete 'overnight' recovery, as indicated by s...

Ventilatory responses of normal subjects to flax dust inhalation: the protective effect of autoclaving the flax.

A homogeneous batch of dew retted hackled flax was divided into two portions. One was untreated and the other was steamed for 45 minutes at 125 degrees C in three pressure/vacuum cycles in an autoclave. Dust was collected when the two flaxes were separately processed by industrial doubler and stapler machines. From untreated flax 7.2 g of dust was collected per kilogram of flax after two proces...

Dust exposure in manual flax processing in Egypt.

Manual flax processing originated in Egypt in 2 000 BC. In the present study a representative sample of the workers involved in this trade, where flax is processed in small workshops or homes, was examined, and their dust exposure was evaluated. The study showed that workers handling and processing flax are exposed to high concentrations of dust; the levels of dust at hackling and combing are c...

Respiratory response in simultaneous exposure to flax and hemp dust.

Zu§kin, E., and Valic, F. (1973). British Journal of Industrial Medicine, 30, 375-380. Respiratory response in simultaneous exposure to flax and hemp dust. The effect of exposure to high concentrations of mixtures of hemp and flax dust was studied in 124 workers in two textiie mills (mill A: 65-70% hemp and the rest flax, mean dust concentration 13 9 mg/m3; and mill B: about 35% hemp and the re...
