Effects of Chemical Exposure with Aerosol Particles through the Human Airways

Inhalation is an important route of exposure to toxic chemicals especially in the work place. Chemicals absorbed by inhalation have specific properties which are gases such as carbon dioxide, vapour and aerosols. (i. e. ) Small particles suspended in air. In this paper the effects of toxic chemicals is due to the inhalation of aerosol particles through the human respiratory tract have been studied Mathematical model is developed for steady laminar flow through the respiratory tract and solved analytically in the presence of first order chemical reaction with particals. The flow is assumed to be symmetrical flow of an Newtonian fluid flowing under constant pressure gradient. The effects of velocity profile, wall shear stress, flow rate, and both homogeneous and heterogeneous chemicals reactions on concentration of air are studied for different Reynolds number, slip parameter, and viscosity off air during light and heavy breathing under isothermal condition by using tylors dispersion model. The solution is numerically computed and the results are depicted graphically
