Influence of traffic-related noise and air pollution on self-reported fatigue

Abstract

A growing body of evidence suggests that exposure to environmental pollutions is related to health problems. It is, however, questionable whether this condition affects working performance in occupational settings. The aim of this study is to determine the predictive value of age as well as traffic related air and noise pollutions for fatigue. 246 traffic officers participated in this study. Air pollution data were obtained from the local Air Quality Control Company. A sound level meter was used for measuring ambient noise. Fatigue was evaluated by the MFI-20 questionnaire. The general and physical scales showed the highest, while the reduced activity scale showed the lowest level of fatigue. Age had an independent direct effect on reduced activity and physical fatigue. The average of daytime equivalent noise level was between 71.63 and 88.51 dB(A). In the case of high noise exposure, older officers feel more fatigue than younger ones. Exposure to PM₁₀ and O₃ resulted in general and physical fatigue. Complex Interactions between SO₂, CO and NO₂ were found. Exposure to noise and some components of air pollution, especially O₃ and PM₁₀, increases fatigue. The authorities should adopt and rigorously implement environmental protection policies in order to protect people.
