A Mathematical model describing the problem of concentration of air pollutants in the atmosphere has been examined. The study unravels the behavior of airborne particles that is aerosols, which play an imperative role in the Earth’s environment. The main motive of the paper is to observe the effects of smog and haze through the concentration of aerosols with and without chemical reaction. A two-dimensional schematic geometry is considered which includes a rectangular channel extended to infinity in the x-axis bounded by porous layers. Assumptions are made that electric and magnetic field are transversely applied while there is heavy rain, thunderstorm and lightning. A general solution of the dimensionless governing partial differential equations is obtained by the perturbation technique with appropriate boundary conditions. In this work velocity, the skin friction coefficient, the concentration of aerosols are numerically computed for different values of various parameters. As a measure to control the effects of air pollutants, significant conclusions are specified for healthier attentive of aerosols concentration properties.
