Negative oxygen ion is not the more the better, 1000-10000/cm?, refreshing enough.
Long stay in the city in a closed room, people will feel dizzy, when coming to the forest beach, waterfalls and other places, will feel refreshed, this is the role of negative air ions.
Oxygen molecules in the air are formed by combining free electrons. Discharge (lightning) phenomenon in nature, photoelectric effect, fountains, waterfalls, etc. can make the surrounding air ionization, the formation of negative oxygen ions. Negative oxygen ion in the medical profession enjoys the "Vitamin", "air vitamin", "longevity factor", "air vitamins
In the medical profession, negative oxygen ions are known as "vitamins of air", "longevity factor" and "air vitamins".
Under the action of cosmic rays, ultraviolet rays, trace element radiation, lightning, etc., air molecules will lose some of the outermost electrons rotating around the atomic nucleus, making the air ionized. The electrons that escape the bonds of the atomic nucleus are called free electrons and are negatively charged. When the free electrons combine with other neutral gas molecules, negatively charged negative air ions are formed.
The above is a natural phenomenon in the generation of negative ions, with the generation of artificial negative ion generation technology and development, according to Xinhua and Guangming Daily and other media reports, artificially generated negative ions have reached the age of ecological negative ions, can produce easy to enter the human body of the negative ions of small particle size.
Expanded Information
Negative oxygen ions are positive indicators of air freshness and judging the quality of the local habitat, is one of the important ecological service products of the natural ecosystems such as forests, wetlands, etc., and is closely related to ecological environmental protection and people's livelihood, and one of the hotspots of concern for all levels of governments and the public society.
In the Outline of the Plan for Promoting the Construction of Ecological Civilization (2013-2020) issued by the State Forestry Administration in September 2013, the negative oxygen ion content in the air is taken as one of the important indicators for the construction of ecological civilization. Through the negative oxygen ion monitoring can be a good response to reflect the air, the quality of human environment and the value of ecological construction to provide ecological products for the society.
In 2014, the State Forestry Administration (SFB) and China Meteorological Administration (CMA) jointly initiated the monitoring of the concentration of negative oxygen ions in the air nationwide, which was undertaken by the Survey Planning and Design Institute of the SFB and the Atmospheric Exploration Center of the National Meteorological Administration (NMA).
The Investigation Planning and Design Institute of the State Forestry Administration has completed the "Preliminary Program of National Air Negative Oxygen Ion Monitoring", and in accordance with the work arrangement, it will select seven cities, including Shiyan in Hubei, Shuozhou in Shanxi, Nanchuan in Chongqing, Shangrao in Jiangxi, Guilin in Guangxi, Lishui in Zhejiang, and Zhangjiakou in Hebei, etc., to carry out joint research on monitoring of negative atmospheric ions.
July 2014, by the State Forestry Administration and the China Meteorological Administration of the relevant personnel composed of technical experts working group, went to the first station of the pilot - Hebei Zhangjiakou for field research on the monitoring of negative atmospheric ions, on the negative atmospheric ions of the monitoring station site selection, operational specifications and other issues for discussion, for the follow-up orderly promotion of air The first stop, Zhangjiakou, Hebei Province, to conduct field research on the monitoring of negative atmospheric ions, and to discuss the selection of sites for negative atmospheric ions monitoring stations and other issues, in order to promote the orderly progress of the subsequent research on negative air ions.
