Air Quality Assessment around Mehrabad Airport

Air pollution is a great concern in developed and developing countries and its economic costs accounts for a large share of gross national product of countries. This study aimed to investigate and assess the air quality around Mehrabad airport.

In this cross-sectional study, important pollutants including CO, TSP, TVOC and NOX were measured. Considering the privaling wind direction in Tehran, one station in residential area, one station representative of the airport, two stations around the airport and one station in high traffic area were selected. LSI-Babuc/A، Dust Trak TSI and Phocheck + 500 were employed to measure the pollutants. Measurement was done in each month and the statistical analysis was done using SPSS 21.

The mean concentration of all pollutants (except for nitrogen dioxide) was higher at the vicinity of the airport stations than in other stattions. Results of the Kruskal-Wallis test showed that there are significance differences between pollutants concentration around the airport and in other stations. No significant difference was found for NO2 among the stations. The mean concentrations of PM10, PM2.5, Co and TVOCs at the north of the airport were significantly different from those of other stations (p<0.001). Discussion and

Most of the pollutants around the airport had higher concentration compared to residential and high traffic stations, and thereby, the airport could be regarded as a pollutant source.
