    Chemical and mechanical air pollution is one of the most crucial problems in scientific studies nowadays. Atmospheric pollution is very hard to be localised or prevented. It can spread not only regionally, but also on a global scale. The notion of air pollution may not be seen only as content of chemical substances or physical components in the air. The air is environment containing various physical fields. The intensity of electromagnetic fields of different frequency (electrostatic and high frequency fields, as well as light, heat, radioactive radiation and other fields) may exceed the level provided in legislation. In this case, the issue of energy pollution appears. Many of the above-mentioned physical fields have an impact on the level of air ionisation providing the air molecules with the energy they need to overcome the ionisation barrier, whish makes the air an environment that continuously contains a certain amount of energy (Sinicina et al., 2013). Consequently, it is possible to speak of the energetic air pollution as a negative phenomenon or to see the energy saturation as a positive feature of the air. For almost a century, scientific studies have been describing the impact of air ions on human beings and other living organisms (Чижевский, 1969; Rim, 1977). Air ions may have favuorable and healing impact or can affect harmfully human health. It depends on their concentration level in the air and on mutual proportions of positive and negative ions.
