摘　　要：目的了解广州市越秀区公共场所室内可吸入颗粒物污染情况,分析其与室外PM_(10)、PM_(2.5)的关系,为改善公共场所室内空气环境提供科学依据。方法对公共场所室内空气中PM10、温度和二氧化碳、一氧化碳进行现场监测,并与室外大气PM_(10)、PM_(2.5)质量浓度进行比较分析。结果在2420个公共场所室内监测点中,PM_(10)总体合格率为93.51%,其中2015年合格率为88.55%,低于2014年的合格率98.96%(P<0.05);2015年公共场所室内监测点PM_(10)质量浓度均数高于2014年(P<0.05)。不同季节、不同类型公共场所室内空气PM_(10)合格率和质量浓度均数均存在差异(P均<0.05)。公共场所室内PM_(10)浓度与室外大气PM_(2.5)、PM_(10)以及空气质量指数AQI存在正相关关系,相关系数分别为r=0.360(P<0.05)和r=0.271(P<0.05)。结论广州市越秀区公共场所室内PM_(10)浓度受到室外空气质量影响,改善室内空气环境需要进一步治理室外环境。Objective To understand the situation of indoor inhalable particulate pollution at public places in Yuexiu area of Guangzhou and analyze the relationship with the outdoor PM10 and PM2.5. and then to provide scientific suggestions for improving indoor air environment of public places. Methods The concentration of PM10, CO2, CO and the temperature of indoor air at public place were monitored, and the relationship with the outdoor atmospheric PM10 PM2.5 and AQI was analyzed. Results The overall qualification rate of PM10 in the 2420 indoor monitoring stations was 93.51%. The qualification rate was 88.55% in 2015 ,which was lower than the qualification rate in 2014（P 〈 0.05 ）. The average mass concentration of PM10 in public places was higher than that in 2015 （P 〈 0.05 ）. The qualification rates and mass concentration average of indoor PMlo were different among seasons, different types of public places （ P 〈 0. 05 ）. The indoor PM10 concentration was positively correlated with the levels of outdoor PM2. 5, PM10 concentration and the A QI （ air quality index）, the correlation coefficients were r = 0. 360 （ P 〈 0.05 ） and r = 0.271 （ P 〈 0.05 ） respectively. Conclusion The concentration of indoor air PM10 at the public places in Yuexiu area of Guangzhou is effected by qualification of outdoor air. In order to improve the indoor air environment, outdoor environment should be further improved.
