Samenvatting
A survey and in-field measurements were undertaken to examine air quality in truck cabins. Preliminary survey results indicated that 99% of the truck drivers opened their windows for air while driving and they believed that the air was fresh. Field measurements showed that the concentrations of CO, CO2, and NO2 in the truck cabin during a two month monitoring period were lower than their respective recommended values. However, thermal comfort level, as indicated by temperature and relative humidity, was out of the recommended level for 93% of the measurement period. Moreover, readings for PM2.5 were within the range of 66-835 ug/m3 which were 1-13 times the recommended value. (A) "Reprinted with permission from Elsevier".
