• Description:
  Exposure to hemp fiber dust for 15 minutes to 3 hours of 3 volunteers (former hemp workers) results in symptoms of byssinosis, and reductions in one-second forced expiratory volume and arterial oxygen tension. The decrease in arterial oxygen tension occurs in men with normal and abnormal one-second expiratory volumes before dust exposure. The decreases of one-second forced expiratory volume and of arterial oxygen (7782447) tension correlate significantly while changes of arterial carbon-dioxide (124389) tension are generally small. Results indicate that hemp exposure causes changes in both gas exchange and lung mechanics. Increased nonuniformity of gas distribution and its effect on ventilation-perfusion relations account for the altered gas exchange. The evidence points to the need for stringent control of dust exposure in textile workers at risk of byssinosis. [Description provided by NIOSH]
