Hookah bars 5 and 5a are the same bar assessed on two nights.
The regulatory standard for PM and CO are Environmental Protection Agency's 24 and 1 h, respectively, National Ambient Air Quality Standards, whereas elemental carbon and nicotine are OSHA's 8 h permissible exposure limits.
BC, black carbon; BDL, below the detection limit; CO, carbon monoxide; EC, elemental carbon; NA, none available; ND, not determined; OC, organic carbon; PM, particulate matter.
