Abstract:
Background

The establishment of automotive industries in urban areas can affect the air quality of cities due to the variety of pollutants emitted from them. The aim of this study is to investigate the simultaneous effects of the Saipa automobile industry and two surrounding highways on air quality.

Methods

In this study, meteorological data suitable for modeling the distribution of pollutants have been prepared from the Mehrabad meteorological station, and the modeling of the distribution of nitrogen dioxide and carbon monoxide gaseous pollutants released from automobile factories and linear sources was done by AERMOD software, and the accuracy of the results It was confirmed by field measurements of NO2 pollution by passive adsorbents.

Results

The validation results show the acceptable performance of the model. The highest annual nitrogen dioxide concentration of 1209 parts per billion can be seen at the coordinates of 515326.80 and 3953279.17 meters inside the Lashkari highway, which is about 23 times the NAAQS standard, and the highest concentration of CO, 12.6 parts per million, can be seen at the coordinates of 515326.80 and 3953279.17 meters inside the Lashkari highway, which is about 1.4 times the NAAQS standard.

Conclusion

The exposure of people passing by on the roads to concentrations higher than the NAAQS standards of nitrogen dioxide and carbon monoxide shows the need for the government and authorities to take action in relation to highways and traffic laws.
