Environmental electromagnetic pollution types, sources, examples

Electromagnetic pollution is the result of the development of human civilization, which harms the entire environment. Pollution of this type began to occur after the invention of Nikola Tesla devices operating on alternating current. As a result, electronic devices, television and radio stations, power lines, technological equipment, X-ray and laser installations, as well as other sources of pollution have a negative impact on the environment.

Definition of electromagnetic pollution

As a result of the operation of sources, an electromagnetic field appears. It is formed by the interaction of multipole and dipole bodies with an electric charge. As a result, various waves are formed in space:

Electromagnetic pollution of the environment types, sources, examples
  • radio waves;
  • ultraviolet;
  • infrared;
  • extra long;
  • hard;
  • x-ray;
  • terahertz;
  • gamma;
  • visible light.
  • The electromagnetic field is characterized by radiation and wavelength. The farther away from the source, the more the radiation is attenuated. In any case, pollution spreads over a large area.

    Emergence of pollution sources

    The electromagnetic background has always been on the planet. It contributes to the development of life, but, having a natural effect, does not harm the environment. So, people could be exposed to electromagnetic radiation, using precious and semiprecious stones in their activities.

    After industrial life began to use devices powered by electricity, and in everyday life electrical engineering, the radiation intensity increased. This led to the appearance of waves of such a length that previously did not exist in nature. As a result, any device that runs on electricity is a source of electromagnetic pollution.

    With the advent of anthropogenic pollution sources, electromagnetic fields began to have a negative impact on both human health and nature in general. This is how electromagnetic smog appeared. It happens both in open spaces, in the city and beyond, and indoors.

    Environmental impact

    Electromagnetic pollution is a danger to the environment because it has a negative impact on the environment. How exactly it happens is not known for certain, but radiation affects the membrane structure of the cells of living organisms. First of all, water is polluted, its properties change, functional disorders occur. Also, radiation slows down the regeneration of plant and animal tissues, leads to a decrease in survival and an increase in mortality. In addition, irradiation contributes to the development of mutations.

    As a result of pollution of this type in plants, the size of stems, flowers, fruits changes, their shape changes. In some species of fauna, when exposed to an electromagnetic field, development and growth slows down, aggression increases. Their central nervous system suffers, metabolism is disturbed, the functioning of the reproductive system worsens, up to infertility. Pollution also contributes to the violation of the number of species of various representatives within the same ecosystem.

    Regulatory regulation

    To reduce the level of electromagnetic pollution, regulatory regulation of the operation of radiation sources is applied. In this regard, it is forbidden to use devices with waves that are higher or lower than the permitted ranges. The use of equipment that emits electromagnetic waves is monitored by national and international institutions, regulatory bodies and the World Health Organization.
