Objectives: This study was conducted in order to evaluate PM10 concentrations at eight highway tollgate booths from July to September 2017.
Methods: A total of 16 samples were collected from eight toll booths. Each PM10 sample was collected using a 37 mm PTFE filter attached to a Personal Environment Monitor.
Results: The geometric mean concentrations of PM10 in the toll booths was 83.51 ㎍/㎥. The mean PM10 concentrations measured on freight roadways were much higher than those of measured on general roadways(102.46 ㎍/㎥ and 68.05 ㎍/㎥, respectively). PM10 was revealed to be higher in the morning(105.59 ㎍/㎥) than at dawn or in the afternoon(71.26 ㎍/㎥ and 61.22 ㎍/㎥, respectively). The mean PM10 concentration in toll booths ventilated through an air conditioner was higher than that for those using a window or no ventilation. The rate of exceeding the Ministry of Environment Maintenance Limit(200 ㎍/㎥) was 6.25%, and the rate of exceeding the Ministry of Labor Recommended Limit(150 ㎍/㎥) was 12.5%.
Conclusions: In order to protect the health of toll booth workers exposed to airborne dust, it is necessary to check the exposure level from indoor air quality on a regular basis and to manage it appropriately according to the results.
