Effect of Atmospheric Pollution on Air Ion Concentration

Impact of Cluster Ions and Air Pollution on Human Health

“…Nowadays, many different indoor air ionisation devices are offered on the market, and their advertising usually emphasises the positive impact of air ions on human well-being, but practically none of them provides for simultaneous control of air ion concentration in indoors. Basing on a previous study [17], [24] it can be concluded that air ion concentration of in the indoor air tends to be variable under the influence of various chemical and physical factors; besides both the level of air ion concentration and unipolarity coefficient are most often in the range that is not favourable to human health and wellness, therefore, in order to improve the air quality, it is recommended to use air ionisers that increase and stabilise air ion concentrations and prevent their natural, often chaotic fluctuations. At the same time, there is a need for a daily control of the level of air ion concentration and for regulation of ionisation intensity to keep it within the required limits, because performance of various electronic devices in offices can change the level of air ion concentration, for example, intensive use of a copier significantly increases the concentration of air ions in the ambient air.…”

“…The author of this article uses and further analyses data on concentrations of light ions and on chemical and physical parameters of the air, as reflected in the doctoral thesis "Impact of Anthropogenic Pollution on Air Ion Concentration" [17]. Concentrations of light air ions, i.e.…”

Progress of negative air ions in health tourism environments applications

“…The displaced electron binds to a nearby molecule, which then becomes a negatively charged ion 25 . Further these two polarities (+or-), also can be physical differentiated by their atomic dimensions and related shapes and electric mobilities, as: small (<1.6 nm diameter, fast molecular agglomerates), large (>30 nm diameter, slow aerosol particles) or intermediate 13 .…”

“…Since charged airborne particles were discovered, their electrical properties are associated with atmospheric phenomena and biological effects. Their interactions influence ecosystems and global climate 13 . Near to the ground, abnormally high air ions concentrations may occur in some microclimates, where temporary exposure can affect the human health by favourable or unfavourable ways.…”

“…Some human activities capable to generate air ions: urban garden (blue/green space), wet sauna, water park, ionization place, artificial ionizers (corona discharges, thermionic electron emission from hot metal electrodes or photo-electrodes, radiation from radioisotopes, UV irradiation, high-pressure water injection, anion 33 incentive, tourmaline and other natural ores), dense urbanization atmosphere, pollution, suspended particles, power lines, industrial and vehicular emissions [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] .…”
