Fig. 1: PAHs included in analysis were detected in 25% or more of samplers (one-way ANOVA p-value < 0.05).

When a PAH was not detected, the LOD/2 was imputed.; A PAH concentrations stratified by sampling ring (one-way ANOVA, p < 0.05). B Values were log transformed to further assess the correlation between distance and PAH concentration (r2 = 0.76, p-value < 0.0001). C Average wristband concentrations stratified by sampling ring. D Values were log transformed to further assess the relationship between distance and PAH concentrations (r2 = 0.53, p-value = 0.0069).
