Analysis of global air pollution, bright prospects for air purification products

Air pollution is a serious environmental problem facing the world today, which is related to human health, ecological balance and sustainable development. With the acceleration of industrialization, the advancement of urbanization and the increase in transportation, the global air quality is deteriorating, which has a profound impact on human life.

1. Main sources of air pollution

Industrial emissions: Waste gas generated in industrial processes is one of the main sources of air pollution, especially in heavy industry and chemical industry, volatile organic compounds (VOCs), sulfur dioxide (SO2), nitrogen oxides (NOx) and other harmful gases are emitted in large quantities.

Transportation: Emissions from vehicles such as cars, airplanes and ships are key factors in urban air pollution, especially in rapidly developing cities, where the exhaust gas emitted by motor vehicles contains a large amount of PM2.5, NOx and CO and other harmful substances.

Construction: Construction and demolition operations are often accompanied by dust and the release of harmful gases, which affect the surrounding environment.

Agricultural activities: Emissions from fertilizers, pesticides and livestock used in agriculture can also lead to an increase in ammonia (NH3) and other harmful substances in the air.

Family life: Coal heating, cooking and household cleaning products containing volatile organic substances are also important sources of air pollution.

2. Impact of air pollution

Damage to health: According to statistics from the World Health Organization (WHO), air pollution causes millions of premature deaths every year. Long-term exposure to air pollution may cause respiratory diseases, cardiovascular diseases, lung cancer and other health problems, especially for children and the elderly.

Environmental problems: Pollutants in the air can cause environmental problems such as acid rain and ozone layer depletion, which seriously affect the balance of the ecosystem. Plant growth is hindered, biodiversity is reduced, and water quality is reduced, which are all closely related to air quality.

Economic losses: Air pollution not only threatens health, but also has a negative impact on the economy. Increased medical expenses, reduced labor productivity and loss of natural resources are directly related to air pollution.

3. National and regional response measures

Faced with the increasingly severe air pollution problem, countries have taken action. Take China as an example. The government has implemented an action plan for air pollution prevention and control, vigorously promoted green energy, strengthened industrial emission supervision, and encouraged the development of public transportation. At the same time, developed countries such as Europe and the United States have passed laws and regulations to limit the emission of harmful substances and promote the application of clean technology.

In addition, the international community is also constantly strengthening cooperation. In 2015, the signing of the Paris Agreement marked the joint efforts of countries around the world to address climate change and its impact on air quality.

4. Common methods to solve air pollution

Although the global air pollution problem is still severe, with the increase of environmental awareness and the advancement of science and technology, it is expected to improve in the future. The promotion of renewable energy, the development of green transportation, and the development of smart cities will provide new solutions for improving air quality. At present, in ordinary households and public places, to solve the problem of air pollution, the first thing is to install air purification products that can filter pollution particles and kill bacteria and viruses.

Air pollution is a global problem that requires countries to work together to strengthen legislation and policy implementation to protect our common home and ensure human health and sustainable ecological development. Only through global joint efforts can the vision of fresh air and healthy life be realized.
