The ecological effects of air pollution and the importance of air pollution control

Atmospheric particulate matter can affect the health of animals and humans, causing various diseases; The chemical composition of the atmosphere can trigger environmental pollution through catalyst factors, such as the London smog; Freon and other greenhouse gases in the atmosphere can destroy the ozone layer, cause the greenhouse effect, and thus cause changes in the ecological environment on a global scale.

Air pollution has become an inescapable reality in the lives of urban dwellers around the world. So where does the importance of air pollution come from?

A report published by the World Health Organization and the United Nations Environment Organization says: "Air pollution has become an inescapable reality in the lives of urban dwellers around the world. "If humans live in very polluted air, they will all die in a matter of minutes.

While industrial civilization and urban development have created tremendous wealth for mankind, billions of tons of exhaust gas and waste have also been discharged into the atmosphere, but the atmosphere on which mankind depends has become an empty garbage reservoir and poison gas reservoir. Therefore, when the harmful gases and pollutants in the atmosphere reach a certain concentration, it will bring great disasters to people and the environment.

The main losses caused by air pollution include:

Harm to organisms - Animals become sick or die from inhaling polluted air or eating food containing pollutants, which can reduce plant disease resistance, affect growth and development, and produce lesions or wilt death on the foliage.

Hazards to articles - such as textiles, clothing, leather, metal products, building materials, cultural artworks, etc., causing chemical damage and defiling damage. Causing acidic rainfall, which adversely affects agriculture, forestry, freshwater aquaculture, etc. Destroying the ozone layer in the upper altitude and forming an ozone hole, which is harmful to the living environment of humans and organisms.

Impact on global climate - such as the increase of greenhouse gases such as carbon dioxide will lead to the increase of the earth's atmosphere, leading to an increase in global weather disasters, and the increase of aerosol particles such as smoke and dust, which will increase the turbidity of the atmosphere, weaken solar radiation, affect the earth's long-wave radiation, and may lead to abnormal weather and climate.

These losses are irreversible, so it is very important to prevent pollution, which is a very important topic in today's society.

Controlling air pollution and improving the natural ecological environment is not only an important responsibility of the party committee, the first and the relevant departments, but also the common responsibility of the whole people and the whole society. It is necessary to persist in all-round mobilization and form a strong joint force to promote the comprehensive control of air pollution. Establish and improve the organizational leadership system, and form a situation in which each level grasps the first level and the first level leads the first level.

Strengthen coordination and linkage between departments, and coordinate the implementation of major issues. Guide enterprises to fulfill their social responsibilities and make due contributions to improving air quality. Mobilize the masses to actively participate and create a good social atmosphere for air pollution control.

Air pollution has a profound impact on entire ecosystems.

First of all, air pollution can lead to reduced photosynthesis efficiency, litter, and even death of plants, which in turn destroys the structure of plant communities and affects the ecological balance of nature. Pollutants such as sulphur dioxide and nitrogen oxides can affect the biochemical effects of the leaves, slowing down their ability to photosynthesize, leading to stagnation or decline in plant growth. In addition, some interfering organic substances can also cause rapid photorespiration, which accelerates plant death.

These plant deaths are also a non-negligible problem for the entire ecosystem.

At the same time, there is also secondary pollution that endangers the ecosystem. For example, nitrogen and sulfur in the atmosphere, deposited into the soil through acid rain, have a direct or indirect impact on the acidity of the soil, which will lead to acidification or alkalinization of the soil, thereby destroying various functions of the ecosystem. In addition, the release of heavy metals and harmful gases in the air into the water will also lead to water pollution, destroy the balance of the water ecosystem, and affect the survival and reproduction of aquatic organisms.

In conclusion, the impact of air pollution on ecosystems is multifaceted, which can disrupt the entire ecological balance and threaten our health and living environment. Therefore, we should take active measures to reduce the generation of air pollution and jointly protect our ecological environment.

Environmental impacts are divided into direct impacts, indirect impacts and cumulative impacts. According to the impact effect, the environmental impact can be divided into beneficial and adverse effects. According to the nature of the impact, the environmental impact can be divided into recoverable impact and non-recoverable impact.

In addition, environmental impacts can also be divided into short-term and long-term impacts, local, regional or national and global impacts, construction phase impacts and operational phase impacts, etc.

Environmental impact refers to the effects of human activities (economic, political and social) on the environment and the resulting environmental changes and the resulting effects on human society and economy.

From a psychological point of view, environmental impact mainly refers to the natural world and human society that have an impact on people. Simply put, it is the objective reality that surrounds the individual, in which the material conditions of life play an important role. The material living conditions of society are not only material benefits and material enjoyment, but mainly refer to the education of the family, school, and workplace.

The material conditions of life in society have a decisive impact on the formation and development of personality, but it does not mean that all personality qualities are determined by the environment. Therefore, in the same unit or family, there may be heroes and criminals punished.

There is a close relationship between the atmospheric environment and human health. There are many factors that contribute to air pollution, such as natural conduction that damages the atmosphere.

Certain human activities can also lead to meteorological events, which can lead to severe atmospheric pollution.

The relationship between the atmospheric environment and human health is as follows:

1.The impact of air pollution on health: air pollutants mainly harm human health in three ways: first, the human surface is harmed after contact; second, the harm caused by people inhaling polluted air; The third is caused by the consumption of food containing contaminants by the slag people.

2.The harm of air pollution to industry: The harm of air pollutants to industry is mainly manifested in the following aspects:

corrosion of buildings and industrial equipment; sabotage of open-pit mine facilities; damage to farmland and reduced agricultural yields; Causing traffic accidents, affecting road traffic and aviation flights, etc. Such as disturbance.

3.The harm of air pollution to the climate: Air pollution can also have a negative impact on the climate, leading to acid rain, photochemical smog and other phenomena, affecting atmospheric radiation and optical properties, making the sky turbid and reducing visibility.

The above is the relationship between the atmospheric environment and human health, I hope it will help to solve your problem.

The main aspects of human factors are as follows: (1) Change environmental factors. For example, human production and living activities produce a large amount of waste gas, waste water, garbage, etc., which are continuously discharged into the environment; Human beings have made irrational use of natural resources or plundered and buried them, such as blind land reclamation, indiscriminate deforestation, over-encirclement of water surfaces, and excessive grasslands.
