# WB = the number of wristbands in which the PAH was detected. * indicates priority PAHs as defined by the Agency for Toxic Substance Disease Registry and/or the United States Environmental Protection Agency, † indicates a PAH detected in both Spring and Winter. PAHs below the level of detection are indicated by (-).
