Information About Author:

A combined model where the vertical impurity dis¬persal was calculated by means of a set of differential equations, such as equations of motion, turbulent dif¬fusion and heat conduction, while the horizontal dis¬persal was computed by a Gaussian model was used. The proposed model is complemented with as¬signed semi-empirical dependences for altitude varia¬tions of wind velocity, turbulent exchange coefficient, atmospheric temperature and turbulence statistics. The calculations done allowed us to estimate the pollution level for different meteorological conditions and pollu¬tion sources and provide recommendations as to how to reduce its disastrous effect on the environment.
