Effects Of Testing And Analysis Of The Environment Of The Highway Toll Station

With the rapid development of China’s economy and the acceleration of urbanization process.The number of vehicles in China is increasing.The pollution of automobile exhaust is caused by automobile exhaust emissions pollution of the environment.The main pollutants including:Hydrocarbons,carbon monoxide,nitrogen oxides,sulfur dioxide,lead compounds,Bap（Benzo A Pyrene）and solid particles,etc.Which cause photo-chemical smog and haze pollution phenomenon.The particulate matter caused by Automobile exhaust emissions,especially PM_2.5 emissions,which is the mainly cause of the smog in city.In addition,The PM_2.5 also can be used as a carrier of other pollutants,which can through the human respiratory system directly into the human blood circulation,cause the greater harm to the human body.At present,the city automobile exhaust particulate matter pollution problem has aroused everyone’s attention,there are large numbers of researches about automotive exhaust emissions.The research on the highway toll station’s PM_2.5 is becoming more and more urgent for us.However,there are not many research about the impact of automobile exhaust towards the expressway toll station,it is a new research in our country and in abroad.In this paper,the influence of the solid particles on the concentration of PM_2.5 in the highway toll station is analyzed,using AEROCET 531 S and 5030 SHARP particle collector.Select the Liucunbao toll station of Xi’an as the main data collection station,and select a number of different pollution conditions of the toll station as a toll station,respectively,PM_2.5 data acquisition.The first is the collected data,according to various monitoring points,different pollution conditions,analysis and comparison of the concentration of PM_2.5 combined with the local toll station near the environment;in addition,select six Fort village toll station specific passenger car traffic data,compared with the PM_2.5 concentration collected,obtained for automobile effect of toll station environment.According to the analysis conclusion,combined with the toll data collection of research and practice,propose effective measures.
