Target and suspect screening were used to identify OH-PAHs in urban air particles. Nine OH-PAHs were determined using the target screening. The concentrations of the target compounds ranged from 20.7 to 96.9 pg/m3. Eleven OH-PAHs were tentatively identified using the suspect screening. Several OH-PAHs were tentatively identified in air particles for the first time.
