Abstract

One of the major environmental problems in large cities is air pollution. In this study, the monthly and annual changes in the average COncentrations of carbon monoxide and PM10 were investigated during a five-year period (winter and fall of 1383-1387 A.H.S) in Tehran. The effects of meteorological parameters on these parameters were also investigated. The study area was divided into three zones (light, medium, and heavy traffic areas). LINEAR REGRESSION was employed to COrrelate [CO] with speed of wind (So W). The significance of changes and the validity of assumptions were evaluated using student’s t-test. COmparison of the data acquired from EO’s in the five-year period indicated that Azadi and Sorkhehesar stations have the most and the least [CO], respectively. Also, Tajrish and Sorkhehesar stations demonstrated the most and the least [PM10], respectively. The AQCC, Bazar and Golbarg stations have the most and the least CO pollution, respectively. Besides, Aghdasieh and Geophysics stations showed the most and the least [PM10], respectively. The highest COncentrations of CO were observed in November and December and PM10 in September. Negative COrrelations were observed between the decrease in [CO] and the increase in the So W. However, no significant relationship was found between the increase of [PM10] and So W.
