This research aimed to study total volatile organic compounds (TVOCs) in gas stations, Korean roast beef restaurants and shopping mall parking lots in the Somdet District, Kalasin Province, measured open air quality simultaneously at all 3 locations using EXTECH All Volatile Organic Compound Analyzer (VFM200) using mean and standard deviation. The results showed that the mean of TVOC in the gas station atmosphere was 616 ± 6.37 ug / m3, the mean TVOC in the Korean BBQ atmosphere was 307 ± 7.59 ug / m3 and the mean of TVOC in the mall atmosphere. At 150 ± 5.43 ug / m3, US EPA requirements (up to 200 ug / m3) show that the air quality of shopping malls is up to standard. And in terms of air quality, gas stations and air quality in Korean BBQ restaurants exceed all standards of VOCs. Therefore, workers should avoid prolonged exposure to volatile organic compounds (TVOCs) and should wear personal protective equipment while working.
