The air of nitrogen oxides including nitric oxide (NO) and nitrogen dioxide (NO2). With the rapid development of industrial production, according to statistics from related departments, especially the large number of mining coal, petroleum, natural gas, the majority of our cities have shown the SO2, NOx depth increases trend. Therefore, the understanding of sulfur dioxide, nitrogen dioxide, oxides of nitrogen source and the mechanism of harm, the establishment of suitable methods of analysis of the nitrogen oxides, and to understand its variation, is of great significance for environmental management and environmental remediation to protect the environment for human survival. With the increase of urban population and motor vehicles in recent years, leading to the concentration of SO2, NOx may have an upward trend, and this carried out on the air, sulfur dioxide, nitrogen oxides determination to understand the transport hub of automobile exhaust in the air of sulfur dioxide and the impact of nitrogen oxides. In this study, the Southern District of Anhui Medical University, near the main roads on both sides to carry out environmental monitoring of air distribution on the basis of preliminary find out its ambient air quality status, draw more than one point of the trunk roa
