Depending on their size, dusts penetrate more or less deeply into the respiratory system: the largest are retained by the upper airways, while the finest reach the lower airways and can impair respiratory function as a whole. Particles reduce the effectiveness of defence mechanisms against infections and interact with pollens to increase sensitivity to allergens. […]

The effects of VOCs vary greatly depending on the nature and concentration of the pollutant: they range from olfactory discomfort, to various irritations, a reduction in respiratory capacity to carcinogenic effects (benzene, etc.). In nature, VOCs, along with nitrogen oxide, are the precursors of ozone.

Carbon monoxide acts like an asphyxiant gas, taking the place of oxygen in the blood, and can be fatal in less than an hour if the level in the air is critical. In the atmosphere, carbon monoxide can combine with oxygen in the air to form carbon dioxide. Together with nitrogen oxides and VOCs, it

Nitrogen dioxide is an irritant gas that penetrates the lungs. It triggers bronchial infections that can be very serious in asthmatics. Nitrogen dioxide is involved in the phenomenon of acid rain, contributing to the impoverishment of natural environments and the deterioration of buildings. It is also involved in the formation of ozone in the lower
