摘要:In this paper,two consecutive weeks of testing were conducted on a local area of a shopping mall garage in Dalian,and the main influencing factors affecting the mass concentration of particulates were analyzed. It is found from the research that the daily distribution of vehicles and customers showed an obvious M-shaped curve, with the peak occurred at 12: 00 and 18: 00,respectively. During the test from 8: 00 to 22: 00,the standardexceeding rate of PM_(2.5) concentration and PM_(10) concentration reached 54.8% and 22.2% respectively. It can be seen from the values of PM1.0/PM_(10) and PM_(2.5)/PM_(10) in the garage that particles with small particle size are the main pollution source of indoor garages. Humidity produced the greatest influence on the concentration of particulates, followed by the hourly average of outdoor meteorological PM_(2.5),the number of vehicles,while temperature produced little influence on the concentration of particulates.
