[Respiratory function study of workers engaged in vinyl chloride and polyvinyl chloride manufacture].
A hygienic evaluation is made on the work conditions in the production of vinyl chloride and polyvinyl chloride. Studies were carried out on 516 workers after the following indices: vital capacity /VC/, forced expiratory volume per sec. /FEV1/, peak expiratory capacity /PEC/, maximum expiratory capacity 75 /MEC75/, maximum expiratory capacity 50 /MEC50/ and maximum expiratory capacity 25 /MEC25/. It was established that 33.13% of the workers were with ventilation disturbances. The most frequently met was the obstructive syndrome of ventilation insufficiency. The infringements were most often in workers with length of service up to 1 year.
