摘　　要：为了了解西安市餐饮业大气颗粒物浓度和分布特征．利用安德森8级撞击采样器采集6家不同餐馆颗粒物样品。并用热光碳分析仪对其中的碳气溶胶进行了分析。结果表明：6家餐馆中．面庄、火锅店和韩国莱馆中颗粒物质量浓度较大，烤肉店中有机碳质量浓度最大，并且有机碳与PM1.1的质量浓度比值为99％，其他烹饪方式的有机碳占颗粒物的比例小于20％；餐馆室内大气颗粒物粒径分布呈双峰模式，主峰集中在小于1．1μm范国内，以PM1.1为主；有机碳粒径分布呈单峰模式，集中在0．43~0．65μm范围内。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 Andvrsen eight-stage ca scade impactor in six restaurants. Carbonaceous aerosols were determined by a carbon analyzer with thermal-optical method. The results shaw 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 PMu 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 fiaction range of less than 1.1μm. OC concentrations have single peak, centering in the range of 0.43 to 0.65 μm.
