Abstract： To understand the characteristics of atmospheric particles and size distributions in indoor environment of restaurants in Xi’an, the particle samples were collected using an Andersen eight-stage ca scade impactor in six restaurants. Carbonaceous aerosols were determined by a carbon analyzer with thermal-optical method. The results show that high mass concentrations of particles are observed in the noodle, hot spot, and Korean restaurants, comparing to the rest of target restaurants. The mass concentrations of organic carbon （OC） are the highest in the barbecue restaurant. The average mass concentration ratio of OC and PM1.1 is 99% in the barbecue restaurant, while it is below 20% in other restaurants. Indoor atmospheric particles in restaurants show bimodal distributions, with the major peak centering in fine fraction range of less than 1.1 μm. OC concentrations have single peak, centering in the range of 0.43 to 0.65 μm.
