Abstract
Thirty-four production workers at three chemical plants were tested for acute changes in lung function over the course of their three-day, twelve-hour workshift. Mean percentages of the predicted lung function indices (FVC, FEV, and FEF 25-75) showed a workshift decrement, particularly evident in the evening shift. A workweek effect was shown in that no recovery in mean %FEV1 and %FEF-25-75 was shown by the last working day. Diurnal variation in respiratory function was regarded as being only partly responsible for the observed workshift effect.This publication has 13 references indexed in Scilit:
