This study was conducted to analyze dust mite allergen and bacterial endotoxin concentrations in the subwaycabins. For this aim, we sampled dust using a vacuum cleaner on cabin seats of subway trains operating in threeSeoul Metro Lines from April to May in 2011. The concentration of dust mite allergen and endotoxin were1,137.51 ± 806.26 ng/g and 5,742.1 (4.68) EU/g, respectively. While, the concentration of dust mite allergen washigher on cabin seats of subway trains in Line B (1,487.61 ± 930.59 ng/g) than on those of trains in Lines A andC (641.9 ± 398.3 and 1,344.9 ± 822.4 ng/g). All measurements did not exceed the National Workshop Guidelineof 2,000 ng/g. While, bacterial endotoxin concentration [GM (GSD)] was higher on cabin seats of subway trainsin Line A [12,373.21 (4.97 EU/g)] than on those of trains in Line B and C8,520.77 (3.98) and 1,631.43 (1.88) EU/g. Dust mite allergen concentrations were strongly influenced by the portion of underground (on the subway line)and endotoxin concentrations were significantly correlated with the number of passengers using the subway lines.Seats for seniors and the week showed relatively higher concentrations compared to seats for general passengers.But, no significant difference of dust mite allergen and endotoxin concentrations in the subway cabins was foundrelating to seat type (p = 0.451, p = 0.564). There was no correlation between the dust mite allergen levels andendotoxin levels in the subway cabins (p = 0.439).
