【Chemical Machinery and Equipment Network Market Analysis】In summer, with the increase of light exposure time and the gradual rise of temperature, the risk of ozone pollution in ambient air gradually increases, which has become the main problem
affecting ambient air quality.
affecting ambient air quality.
Recently, the Ministry of Ecology and Environment released the results of the national air quality forecast meeting for the first half of July, showing that in the first half of July this year, that is, as of July 15, most of China's diffusion conditions were good, and the air quality was mainly
good to light pollution.
However, due to the rise in temperature, moderate ozone pollution processes
may occur in North China, north-central East China, Chengdu Plain, Sichuan Basin, and Guanzhong in Shaanxi.

Ozone - "Earth umbrella" or "invisible destroyer"?
Ozone is an allotrope of oxygen, colorless at room temperature and pressure, and odorless
at low concentration.
At an altitude of about 20-50 kilometers above the Earth's surface, there is a layer of ozone, which absorbs most of the ultraviolet rays in sunlight and protects life on Earth from harm

.
But near the ground, ozone has a different face
.
When the maximum 8-hour average ozone concentration exceeds 160 micrograms per cubic meter, ozone pollution
is formed.
If it exceeds 215 μg/m³, moderate contamination is achieved; If it exceeds 265 micrograms per cubic meter, it is heavily polluted

.
Experts introduced that if the ozone concentration in the air near the ground is too high, it is easy to cause inflammatory lesions of the upper respiratory tract, cough, headache and other symptoms, and irritation to the skin, eyes, and nasal mucosa; Ozone can also destroy the barrier function of the skin, causing skin diseases, dark spots, etc

How does ozone pollution form?
The so-called ozone pollution refers to the photochemical reaction of precursors such as volatile organic compounds (VOCs) and nitrogen oxides (NOx) under solar radiation, resulting in the phenomenon that the concentration of ozone near the ground exceeds the standard
.
Therefore, ozone concentration is not only closely related to the emission intensity of precursors such as VOCs and NOx, but also affected by factors such as temperature, radiation, humidity, and wind speed

The Ministry of Ecology and Environment reported that from January to May this year, the average concentration of ozone in 339 prefecture-level cities and above in the country was 138 micrograms / cubic meter, an increase of 8.

Precise control of ozone pollution is inseparable from scientific and technological support
Since 2013, China has included ozone in the regular monitoring
of air pollutants.
Monitoring data show that in the past five summers (May to September), the average concentration of ozone in the country has remained at about 150 micrograms / cubic meter, and the average proportion of days when ozone exceeds the standard is 11.

For the prevention and control of ozone pollution, the "Opinions on Fighting the Battle against Pollution in Depth" has made arrangements, proposing that while continuing to promote the prevention and control of PM2.

Entering the "14th Five-Year Plan" stage, driven by the "dual carbon policy" and sustainable development strategy, the VOCs governance industry has ushered in a golden opportunity
.
First of all, from the perspective of technical concepts, with the wide application of big data, cloud computing, and Internet technology, smart environmental protection has become the mainstream trend, and in view of the characteristics of wide sources of VOCs pollutants and difficult supervision, smart monitoring has become the premise
of accurate and efficient governance.
At the same time, the concept of coordinated treatment of VOCs and other air pollutants has been widely resonated, which also makes the VOCs treatment industry chain continue to extend and the subdivision track more abundant
.
According to industry assessments, it is expected that by 2025, the market size of the VOCs governance industry will exceed 130 billion yuan

At present, Beijing has taken the lead in establishing a volatile organic compound monitoring system combining points, lines and areas in the country, using manual monitoring, automatic monitoring, navigation monitoring and other technical means to provide accurate technical support
for the coordinated treatment of PM2.
