Hookah bars 5 and 5a are the same bar assessed on 2 nights. ND = not determined; BDL = below the detection limit; NA = none available. The regulatory standard for PM and CO are EPA's 24 hr and 1 hr, respectively, National Ambient Air Quality Standards, whereas elemental carbon and nicotine are OSHA's 8 hr Permissible Exposure Limits.
