Can you talk about how the soil pollution we experience is formed?

Do you know what soil pollution is? What are the causes of soil pollution? Soil contamination has become a major challenge to build a healthy environment.

So, today let's find out what soil pollution is and how does it happen? I believe you must be wondering what exactly is soil pollution?

Soil pollution refers to the abnormal toxic substances contained in the soil, such as garbage debris, toxic chemicals, etc. In other words, soil contamination occurs when the level of this toxic and harmful substance in the soil increases enough to cause serious damage to living organisms such as plants, animals, and humans. What causes soil pollution?

There are many factors that contribute to soil pollution. From the waste generated by large factories, to the overuse of pesticides on agricultural land, to the trash we throw away at home and school, the waste we create is one of the most polluted on the planet. Garbage collected from home or school is taken to landfills, where it is buried in the soil and decomposes over time.

Decomposition releases the greenhouse gas methane, which can contribute to global warming.

Not only that, but different kinds of soil contamination can adversely affect the health of animals and humans, as harmful chemicals entering the soil and water can cause cancer, deformities, and many other problems. Knowing about soil pollution, what can we do to prevent it? As people say, if you want to change the world, you have to start with yourself, starting with the little things like garbage in life, which will have a huge impact on protecting the environment.

The best way to control waste is to reduce production, such as not using paper towels or napkins. Drink from a glass, not from a plastic bottle, and make sure to dispose of hazardous waste such as batteries and computer equipment properly. Everyone acts together, and soon there will be a clean environment.

Do you know? The planet loses 24 billion tonnes of topsoil every year due to land pollution.

Causes of soil pollution Waste gas, waste water, and solid waste discharged from the production and operation activities of enterprises. Agricultural production activities, such as sewage irrigation, chemical fertilizers, pesticides and agricultural films, livestock and poultry breeding, pollutant emissions, etc.

There is excessive use of pesticides, or illegal emissions from enterprises to form soil pollution. When burning, this is only part of the reason.

It's because we litter the soil, and there is a lot of plastic pollution in it, which will affect our soil.

The main reasons to come include:

First of all, the waste gas, waste water and waste residue discharged from the production and operation activities of industrial and mining enterprises are the cause of it.

The main cause of soil pollution around DAO. The accumulation of various solid wastes such as tailings slag and hazardous waste leads to soil pollution around it. Vehicle exhaust emissions lead to soil pollution of heavy metals such as lead and zinc and polycyclic aromatic hydrocarbons on both sides of traffic arteries.

Secondly, agricultural production activities are an important cause of cultivated soil pollution. Sewage irrigation, irrational use of agricultural inputs such as fertilizers, pesticides, and agricultural films, as well as livestock and poultry breeding, lead to soil pollution of cultivated land.

In addition, the high natural background value is the reason for the excessive heavy metals in the soil in some regions and watersheds.

Due to the rapid growth of population and the rapid development of industry, solid waste is constantly piled up and dumped on the soil surface, harmful wastewater continues to penetrate into the soil, and harmful gases and dust in the atmosphere continue to fall into the soil with rainwater, resulting in soil pollution.

Summary. Dear, I'm glad to answer your questions. Looking at the relationship between soil pollution and our lives, whether we live in high-rise buildings, soil pollution will not be harmful to us

The problem of soil pollution is closely related to our lives, and the continuous deterioration of the soil environment may not only lead to a decline in the quality of human life, but also further threaten food production and even lead to survival problems. The current situation of soil presentation is that the soil in many areas shows different degrees of loss of ecological functions, and also shows a variety of signs of pollution, including cadmium, mercury, lead, arsenic, copper and other heavy metal pollution.

How do we see the relationship between soil pollution and our lives? If we live in tall buildings, soil contamination won't work for me.

How do we see the relationship between soil pollution and our lives? Do we live in tall buildings where soil contamination doesn't harm us?

OK dear, I'm glad to answer for you. Looking at the relationship between soil pollution and our lives, whether we live in high-rise buildings, soil pollution will not be harmful to us: soil pollution is closely related to our lives, and the continuous deterioration of the soil environment may not only lead to the decline of human quality of life, but also further threaten the production of food in the grain and mountain areas and even lead to the emergence of survival problems.

The current situation of soil presentation is that the soil in many areas shows the same degree of loss of ecological function, and also shows a variety of signs of pollution, including cadmium, mercury, lead, arsenic, copper and other heavy metal pollution.

Hello, dear and dear, expand information for you: The relationship between soil pollution and our lives: Soil pollution has a great impact on the environment, and some will lead to vegetation destruction, soil erosion, and land desertification.

Pollutants will endanger people's production and life with surface runoff and underground infiltration. Due to the limited ability of soil to degrade itself, crops and other crops will absorb heavy metal substances in pollutants, and most of them contain substance A. Long-term consumption of polluted groundwater and consumption of contaminated food crops can bring significant risks to one's own lives.

That's why we need to take care of the environment. Avoid pollution and resolutely resist all behaviors that are harmful to the environment. Everyone has the responsibility to protect the environment, and protecting the environment is to protect oneself.

Once soil contamination is caused or discovered, it is less likely to be revived simply by cutting off the source of the contamination. In contrast, the cost of soil pollution control is greater, and the problems of high cost, long cycle and difficulty are all realities in front of us.

<> "Soil Pollution. Soil refers to the loose layer on the earth's land surface that is composed of minerals, organic matter, water, air and microorganisms where plants can grow. When pollutants produced by human activities enter the soil and accumulate to a certain extent, causing the deterioration of soil quality, and then causing some indicators in crops to exceed the national standard, it is called soil pollution.

Soil contamination can lead to reduced crop yields and agricultural product quality, pollute groundwater and surface water, affect the quality of the atmospheric environment, and endanger human health.

Compared with air pollution and water pollution control, soil pollution is hidden and cumulative, not only invisible and invisible, but also will not be visible quickly, often after 10 or 20 years before it can be revealed. As a result, soil contamination often lags a long time from the time it is contaminated to the time it becomes problematic.

There are four main categories of soil pollutants:

First, chemical pollutants, including inorganic pollutants and organic pollutants;

The second is the change of physical pollutants, which refers to solid wastes from factories and mines, such as tailings, waste rock, fly ash and industrial waste;

the third is biological pollutants, which refer to urban garbage with various germs and waste water and waste discharged by sanitation facilities;

Fourth, radioactive pollutants, mainly in the mining of nuclear materials and the nuclear areas of the atmosphere, mainly strontium and cesium and other radioactive elements with a long survival time in the soil.

Although the soil itself has a certain purification capacity, when the pollutants entering the soil exceed the environmental capacity of the soil, soil pollution will be formed, which will have a serious impact on the soil ecosystem, and will also enter the human body through the food chain, causing harm to human health. Contaminated soil can be remediated to restore the contaminated soil to normal function.

Soil remediation is the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil to reduce their concentration to acceptable levels, or to convert toxic and harmful pollutants into harmless substances. Fundamentally, the technical principle of contaminated soil remediation can be summarized as changing the form of pollutants in the soil or the way they combine with the soil, and reducing the migration and bioavailability of the nucleus in the environment. and reducing the concentration of harmful substances in the soil.

In order to protect and improve the ecological environment, prevent and control soil pollution, protect public health, promote the sustainable use of soil resources, promote the construction of ecological civilization, and promote sustainable economic and social development, the Fifth Session of the Standing Committee of the 13th National People's Congress passed the Law of the People's Republic of China on the Prevention and Control of Soil Pollution, which has been implemented since then.

The formulation of the Soil Pollution Prevention and Control Law is of great significance, first, to implement the decision-making and deployment of the first law on the prevention and control of soil pollution.

The second is to improve the socialist legal system with Chinese characteristics, especially the legal system for ecological environmental protection and pollution prevention and control.

The third is to provide legal guarantees for China to carry out soil prevention and control work and solidly promote the "Pure Land Defense Campaign".

Soil pollution refers to the environmental problems caused by the discharge and release of harmful substances generated by industry, agriculture, mining and other activities in human activities, which exceed the purification capacity of the soil itself.

Soil is an important material base in the ecosystem and plays a key role in maintaining the survival and development of organisms. However, with the increasing number of human activities, a large number of toxic or harmful substances such as wastes, chemicals, and heavy metals will seep into the soil through air, water and other ways, and accumulate and spread in the soil, thereby destroying the structure and function of the soil, endangering ecological security and human health. The effects of soil pollution range from reduced crop quality and yield, groundwater contamination, degradation and loss of ecosystems, and threats to human health.

It should be noted that soil pollution is a complex environmental problem, and its treatment needs to be comprehensively considered and planned in terms of policy, law, technology and social participation. **Relevant regulations and standards should be improved, supervision and law enforcement should be strengthened, and environmental responsibility and self-discipline of enterprises and individuals should be promoted.

There are many kinds of soil pollutants, and after these pollutants enter the soil, they have different destinations due to different properties, and soil pollutants mainly have the destinations of fixation, volatilization, degradation, dispersion and leaching.

Heavy metals are the most common soil pollutants, after the soil is polluted by heavy metals, it is difficult to restore its original soil capacity, and after the heavy metal ions pollute the soil, it is mainly to make the soil inorganic and organic colloids have stable adsorption separation.

seeds, so most of them will be fixed in the soil and difficult.

After the exclusion, heavy metal contamination can also cause some.

chemical reactions, alleviating its toxic effect, but on the soil ring.

There is still a lot of pollution.

At present, China's agriculture has developed rapidly, and agriculture is noisy.

The level of technology is constantly improving, and the use of chemical fertilizers and pesticides is increasing, although the use of these chemicals can increase the yield of crops, but improper use can seriously pollute the soil. When the amount of chemical fertilizers and pesticides used for destruction in agriculture is excessive, these chemicals remain in the soil, and it is not easy to remove them in time.

After chemical pesticides enter the soil, they mainly disappear from the soil through volatilization and degradation, and the volatilization speed of different chemical pesticides is different, and the strength of their volatilization mainly depends on their own solubility and the temperature, humidity and structural condition of the soil. Most of the herbicides used today are photochemically degradable, and many pesticides are organic compounds that can also be biodegradable.

When heavy metals and pesticides contaminate soil, they can be lost or dispersed by runoff from the ground. Crops absorb heavy metals and pesticide residues from the soil, which can also be transferred to the environment, where they can enter livestock and humans through food. Fighter.

In addition, the excessive nitrogen fertilizer applied into the soil can also occur a series of redox reactions in the soil to form carbon monoxide and other substances, which are easy to leach and pollute groundwater.

Taking heavy metal pollution in the soil as an example, if there is soil heavy metal pollution in the plot where wheat is planted in the canopy, different concentrations of heavy metals will be detected in the wheat at different stages of growth and growth, and once it enters the wheat, as the human at the top of the food chain, the heavy metals will continue to accumulate into the human body with the food chain.
