The development of ozone therapy, and how to control ozone?

1. Tropospheric ozone pollution. Ozone in the stratosphere can absorb short-wave ultraviolet radiation, reduce harm to humans, animals and plants, and is the umbrella of life on earth. The presence of tropospheric ozone not only affects the oxidation of the atmosphere, but also participates in the chemical transformation process of a variety of atmospheric pollutants due to the strong oxidizing property of ozone, and causes harm to human beings, ecosystems, and urban construction.

2. Harm to the human body. Ozone can also participate in the reaction of unsaturated fatty acids, amino groups and other proteins in living organisms, so that people who are directly exposed to high concentrations of ozone for a long time have symptoms such as fatigue, cough, chest tightness and chest pain, wrinkling, nausea and headache, rapid pulse, memory loss, and vision loss.

3. Other hazards. Ozone can also make plant leaves yellow or even wilt, causing damage to plants, and even causing a reduction in the yield of agricultural and forestry plants, and a decline in economic benefits.

According to reports, data show that in the first half of this year, the average proportion of air quality compliance days in cities in Guangdong Province was within the average, ozone has replaced fine particulate matter), which has become the primary air pollutant in the province.

According to the report, relevant research and practice show that to control ozone pollution, it is necessary to reduce nitrogen oxide and volatile organic compound emissions in accordance with a certain proportion, and adopt differentiated control strategies in combination with local pollution status, industrial characteristics, and economic and social development levels.

Researchers at the National Urban Environmental Pollution Control Technology Research Center said that ozone control is a long-term process, ozone is mainly gaseous, and wearing a mask can not be effectively protected, the best way is to avoid contact, and when the sun is strong in the afternoon, it is necessary to stay away from places such as roadside and decoration pollution, children, the elderly and other sensitive groups, try not to go out in the sun.

In addition, ozone precursors are also precursors of secondary particulate matter, with the deepening of the treatment work and the continuous promotion of nitrogen oxides and volatile organic compounds emission reduction, ozone can be effectively controlled, and a number of enterprises involved have been notified for investigation and punishment, which has effectively promoted the acceleration of prevention and control work.

It is hoped that the problem of ozone pollution can be effectively dealt with as soon as possible

Department of Environmental Monitoring, Ministry of Ecology and Environment.

Liu Zhiquan, director of the department, introduced that the three main reasons for the current ozone pollution problem are that its precursors - nitrogen oxides and volatile organic compounds emit large emissions, especially volatile organic compound emissions, which are large and scattered, and have not been effectively controlledSecond, the high temperature and strong sunlight weather continues; Third, the proportion of nitrogen oxides and volatile organic compounds in the emission reduction process may be uncoordinated, resulting in an increase in ozone concentration.

Scientific research data show that ozone near the ground is mainly produced by precursors such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) through photochemical reactions under light conditions. Controlling ozone pollution boils down to reducing emissions of volatile organic compounds (VOCs) and nitrogen oxides, which are also precursors for conversion production.
