One of the most severe environmental problems is air pollution. Cancer, cardiovascular disease, and high mortality rates are also possible side effects. In cities and urbanized areas, high population density is a significant contributor to air pollution. The primary air pollutants to be concerned about are suspended particles and polyaromatic hydrocarbons. The high CO concentration in heavy industry is a significant source of pollution. This study aims to compare concentration levels before and after the construction of certain industrial plants. It included air pollutants as well as meteorological variables.
