A ir quality is becoming an essential environmental issue in nowadays [1][2][3] Researchers have been interested in air quality due to severe health problems caused by air pollution as it is one of the factors that effects the nature of human beings [1,4]. Air pollution have been considered as one of the most important environmental concern especially for urban areas due to their high population and industries [4,5]. There are a number of pollutants that are also known ground-level air pollutants, namely PM10, O 3 , CO, NO x , NO, NO 2 , H 2 S and SO 2 [6]. Nitrogen oxide, generally known as NO x , is a common term for compounds include oxygen and nitrogen such as NO 3 , NO, N 2 O, N 2 O 3 , NO 2 , N 2 O 4 , and N 2 O 5 [7, 8]. Combustion emissions and vehicle exhaust are the main source of NO x [9, 10]. NO x emissions can cause acid rains and photochemical smog that has an effect on human health (such as infection, cancer, etc.) and air quality [9]. Inhaling NO x is associated with increased health problems including respiratory disease, difficulty in breathing, and premature death [11]. Moreover, accumulation of NO x , that is come from the air into water, lowering the Article History:
