China s ambient air quality improved in the first half of the year, how to increase ozone concentrat

Introduction: If you want to increase ozone concentrations, you need to emit more carbon monoxide.

Methane and other pollutants are fine. With the continuous improvement of social living standards, more and more people have begun to pay attention to environmental issues. In terms of the atmosphere, there is a lot of concern about the situation of ozone. For the ozone layer.

We need to not only protect the ozone layer, but also consciously reduce the concentration of ozone. There are two main reasons for this contradictory view and approach to the ozone layer. The first is that the ozone layer does not only absorb ultraviolet light.

And it can protect life on Earth.

The second aspect is that the ozone layer not only causes harm to human health, but can also cause various diseases. When it comes to the ozone layer, many people probably only know that the ozone layer can absorb ultraviolet rays. Aside from this, people may not know much about ozone.

Ozone is not only a gas in the atmosphere, but it is mainly found in the atmosphere.

in the stratosphere.

Ozone has a two-sided effect on human development. Although ozone protects all living things on the planet, it can also have a great impact on human health.

Although ozone can absorb ultraviolet rays, ozone can also cause serious harm to crop production and the ecological environment. Because ultraviolet rays are very harmful to the human body, people need the ozone layer. If you want to increase the concentration of ozone, you need to emit some gases.

Although it is necessary to protect the ozone layer, ozone has become a polluting gas in recent years. Netizens who are concerned about ozone may have noticed such a piece of information, China's ambient air quality in the first half of the year.

Overall improvement. <>

As soon as such a good news was issued, it attracted the attention and support of many netizens. Thanks to the joint efforts of relevant departments and people, China's ambient air quality has finally improved. Although China's air quality has improved, it can be found that ozone has become a polluting gas that endangers human life.

If you want to reduce ozone concentrations, you have to deal with ozone pollution**. Near-surface ozone mainly comes from coal, oil refineries, etc.

I think that if we want to increase ozone concentration, first of all, we should do a good job in environmental protection, and we should also do a good job in corresponding preventive measures, China wants to increase ozone concentration, but also strengthen the appeal to the world to strengthen the environmental governance of various countries, which is more conducive to the improvement of the environment.

There is a need to strengthen the protection of the air without damaging the environment, to reduce carbon dioxide emissions, to increase air concentration, and to pay attention to environmental protection, so that ozone concentrations can be increased.

Now there has been a very big change in environmental pollution across the countryAir qualityIt is getting better, and the number of days of heavy pollution weather throughout the year is also slowly decreasing. From the perspective of the city where I live, the effectiveness of environmental governance is that you can see the stars on a summer night, and you can see the blue sky and white clouds in the city for a long time.

According to the report data, China's ambient air quality in the first half of the year has been effectively improved, and ozone concentration has also increased. This is a good phenomenon, and it also allows us to see the good results brought about by attaching importance to environmental protection.

Ecological environmental protection is not a slogan in our country, but a commitment to be fulfilled with great efforts. The path of rapid development in the past has brought serious damage to the ecological environment; When nature gives us its power, it also makes us realize that ecological and environmental protection is as important as development and construction.

Many places that were once heavily polluted have significantly improved their ecological environment after years of treatment. In the city where I live, many heavily polluting enterprises have been shut down, and the once smelly ditches have been turned into green water ecological parks. The urban environment is beautifying and improving, and our living circle is getting better and better.

In the past, it was difficult to see blue skies and white clouds in the city, and even after the rain in midsummer, the weather gave people a gray feeling, so that I always thought that the sky was a little dark, which was a precursor to an imminent thunderstorm.

After years of environmental management, the number of smog days in the city has been reduced, and even in winter, you can see blue skies and white clouds. Although there are occasional smog days, this is not due to a single city, but to the overall climate and environment.

The management of the atmospheric environment and ecological environment is a matter of paying and reaping. As long as we are willing to invest time and energy, we will definitely exchange for green mountains and green waters, as well as white clouds and blue skiesThe good lifeEnvironment.

China's environmental pollution has improved, since the beginning of the implementation of garbage classification, China's environment is getting better and better, and the air has become much fresher.

As of today, China's air quality has improved in a wide area, and among the 338 cities, the original heavily polluted cities have dropped from 104 to 27, and there are no seriously polluted cities.

Ozone in the air can effectively block the damage of ultraviolet rays to the human body and crops. The reason why ozone near the ground is classified as a pollutant is because of its strong oxidizing nature, which will cause damage to the human respiratory system, nervous system, ** and immune system, and the ecological environment will also have certain harms, including damaging plant foliage, reducing crop yields, and accelerating the aging of building materials.

Ozone is a secondary pollutant, which is generated by photochemical reaction of nitrogen oxides and volatile organic compounds emitted from automobile exhaust, industrial production and domestic non-point sources under the action of light.

In 2012, China's revised implementation of the "Ambient Air Quality Standards" added ozone control indicators, the daily evaluation of ozone pollution, not to the daily average concentration value of the evaluation, but to the daily ozone concentration of the maximum value of the 8-hour moving average value of the evaluation, the maximum value of the 8-hour moving average value of more than 160 g m3, the air quality is not up to standard.

It can cause photochemical pollution. Ozone, also known as photochemical oxidant, is used to block ultraviolet rays when ozone is used to block ultraviolet ozone, strong oxidation, and a small amount of ozone in the air after a thunderstorm makes people excited.

The Ministry of Ecology and Environment said at a press conference that China will continue to promote the coordinated management of ozone, and China has also achieved very good results in this regard, and China's air conditions have also been significantly improved, of course, this policy needs to be continued. Ozone is a major contributor to air pollution, which not only harms human health, but also adversely affects the survival of other organisms in nature. At present, in the treatment and control of ozone, relevant measures should be formulated based on the characteristics of ozone, and with the improvement of scientific and technological level, some methods with less environmental pollution, such as biological enzyme treatment, can also be adopted.

Ozone can exist in the atmosphere for a long time, so it can spread from one place to another far away, and it is very easy to cause pollution in a region as a whole, so the treatment of ozone should achieve joint prevention and control between different regions. At the same time, although China has been advocating the reduction of exhaust emissions, if the emission reduction is not scientific and reasonable, it will cause an increase in ozone concentration, because the formation of ozone is related to the proportion of precursors.

The precursors of ozone are very different, so this makes it difficult to control. In order to make ozone more effective, it is necessary to increase the pertinence and precision, that is, to accurately control the emission of ozone precursors. The development of the field of biology is very rapid, and the application of biological enzymes in various fields is becoming more and more extensive, and very good effects have been found in the treatment of ozone.

Biological enzymes are enzymes extracted from organisms that exist in nature, so they are harmless to the natural world and pollution-free to the environment. In addition, biological enzymes have the characteristics of small amounts and high efficiency, so the use of biological enzymes to treat ozone is a very cost-effective choice.

In fact, in terms of ozone control and emissions, it needs to be composed of many departments, and even all countries in the world work together, rather than referring to one-way behavior.

Data show that in the first half of this year, the average proportion of air quality compliance days in cities in Guangdong Province is that ozone has replaced fine particulate matter) as the primary air pollutant in the province.

It is necessary to conduct in-depth research on the characteristics and transmission laws of ozone pollution in key areas, scientifically delineate ozone joint prevention and control areas, and establish a closed-loop VOCs governance system of standards, monitoring and law enforcement with VOCs and NOx coordinated emission reduction as the starting point, and adhere to the whole-process control technical route of source substitution, process control and end emission reduction.

1. The current situation and characteristics of ozone pollution in Zhuzhou City were analyzed by using the automatic air quality monitoring data in January and December 2013. The results showed that during the monitoring period, the annual exceedance rate of the maximum 8-hour average concentration of ozone attack was only the standard, and the standard value of one beat of burning pants reached the standard rate.

2. The monthly variation of the maximum 8-hour average concentration of ozone per day was m-shaped, and the high concentration value lasted for a long time. The daily variation pattern in the middle of the period was strong, and the variation law of the four seasons was slightly different.

Since September 1, Guangdong Province has launched a three-month special action to prevent and control ozone pollution.

In the first half of this year, the average proportion of air quality compliance days in cities in Guangdong Province was that the air pollution prevention and control situation was still good, but the headache is that ozone has replaced fine particulate matter) as the primary air pollutant in the province.

In fact, in many cities, ozone has become the leading air pollutant in the summer. Some people are worried that the photochemical smog incident that occurred in Los Angeles will occur locally in China.

In this regard, Liu Bingjiang, director of the Department of Atmospheric Environment Management of the Ministry of Environmental Protection, responded positively at a recent press conference held by the Ministry of Environmental Protection: "China is highly concerned about the historical lessons of developed countries, and is effectively strengthening ozone monitoring and taking treatment measures. "Many people confuse the difference between "ozone layer" and "ozone".

Most of the ozone in nature is distributed in the atmosphere at a distance of 15 to 30 kilometers from the ground, known as the "ozone layer", which can effectively block ultraviolet rays and protect human and other health. With the intensification of human activities, a serious hole has appeared in the ozone layer on the earth's surface. In order to reduce ozone-depleting substances, the international community has formulated the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer.

Protecting the ozone layer is the most successful global cooperation to date. On 23 January 1995, the United Nations General Assembly also decided that 16 September of each year should be designated as the International Day for the Protection of the Ozone Layer.
