Abstract Background and Objective: Air pollution can harm humans and the environment. To reduce the effect of these parameters in the emissions of air pollutants known to the local topographical features and climatic conditions are factors. The purpose of this study, monthly and seasonal variations are contaminants and their relationship with meteorological parameters. Methods: the presen...

The height of mechanical mixing layer is one of the parameter of the safety analysis report of any industrial (nuclear) facility due to its relation to the dispersion factor of pollutants. It can provide information about lower atmospheric dispersion, which is usually used to study the pollutants released from nuclear facility, risk analysis and emergency planning. Mixing layer height is diffic...
