Respiratory response in simultaneous exposure to flax and hemp dust.

摘要: Abstract Žuskin, E., and Valic, F. (1973).British Journal of Industrial Medicine,30, 375-380. Respiratory response in simultaneous exposure to flax hemp dust. The effect high concentrations mixtures dust was studied 124 workers two textile mills (mill A: 65-70% the rest flax, mean concentration 13·9 mg/m3; mill B: about 35% 15·8 mg/m3). A prevalence byssinosis found both (80% B; 46·8% A) after a no more than 13 years. In mills, byssinotics had higher all chronic respiratory symptoms non-byssinotics. This difference pronounced A. Forty-eight percent byssinotic women 43% men grade 2 or 3. Significant acute reductions FEV1·0 ˙Vmax 50% VC on Monday were recorded subjects with without significantly larger reduction (FEV1·0, P < 0·01; VC, 0·05). proved be sensitive test for detecting effects vegetable FEV1·0. exposed similar different proportions equal.
