Smoke samples from the exhaust of kitchens including Chinese, Japanese and western restaurants, in both gas and particulate matter phases, were collected and analysed for 21 PAHs by GC/MS. The results revealed that PAH has mass distribution of 74.5% mainly in gas phase from the exhaust of 11 restaurants. The range of total PAHs concentration is between 39.5 ~ 450 μg/Nm3, and the average is 120 μg/Nm3. Simultaneously, the concentration of ΣHM-PAHs (5-, 6- and 7-rings) is between 15.9 ~ 207 μg/Nm3, and the average is 38.7 μg/Nm3. However, with individual highest carcinogenic potential of the BbF+BaP +DBA concentration is between 5.34 ~ 21.0 μg/Nm, the average is 14.4 μg/Nm3; total-BaPeq concentration range is 7.79~14.9 μgBaPeq/Nm3, and the average is 11.4 μgBaPeq /Nm3. Among 11 restaurants, Japanese- style barbecue restaurant has the highest total-PAHs, ΣHM-PAHs, BbF+BaP+DBA, total BaPeq emission concentration, and following by fast-food restaurant, a Chinese restaurant , and Western-style restaurant. Also different type of Restaurants, their total-PAHs emission factor for Japanese-style barbecue (4130 mg/L-oil) is the highest, and followed by fast food (3010 mg/L-oil), a Chinese restaurant (772 mg/L-oil), Western-style restaurants has the lowest emission factor (215 mg/L-oil) among those restaurants. Finally, The collection efficiency for Flue gas control equipment including pilot-scale ESP and wet scrubber are between the range of 60.0% to 69.8% for PAH removal..
