Emission and air quality standards - Jefferson Alex Maciel Cavalcante - Bog

When an alteration occurs, and with it the degradation of the air, the photosynthetic processes are compromised and the terrestrial and aquatic vegetation is harmed; the nitrogen, oxygen, and carbon cycles are harmed, causing climatic changes; there is a decrease in the intensity of light; the water and the soil are affected, damaging the health of humans and animals. It is important to point out that, even if the emissions are maintained, the quality of the air can change as a function, basically, of the meteorological conditions that determine a greater or lesser dilution of the pollutants. This is why it worsens during the winter months, when weather conditions are more unfavorable to the dispersion of pollutants. The interaction between the sources of pollution and the atmosphere will define the air quality level, which in turn determines the appearance of the adverse effects of air pollution on the receptors.
