Is burning straw seriously polluting the environment? On what basis?

Straw burning is polluting to the air. But not absolutely, Chinese farmers have been slash-and-burn for thousands of years, burning straw and then planting a crop, and I have not heard of great harm. In addition, after burning straw, you can reduce pests and diseases, reduce all kinds of weeds, and the land is like sprinkling a layer of fertilizer, making the land more crisp and loose, so why not.

On the contrary, there are now all kinds of enterprises everywhere, and their emissions in one day are not enough for farmers to burn in a year. So the real pollution is coming from the businesses, not the farmers. ‍‍

Burning straw only has an impact on environmental pollution, but it is not to the point of seriousness, China has thousands of years of crop planting history, the burning of straw is more serious than now, if the burning of straw is serious to the environment, then our environment is not so good.

Burning straw has a certain impact on the environment, anything has a certain impact on the environment during the combustion process, and straw is the same in combustion, straw burning produces a large amount of carbon dioxide and harmful soot, which can easily cause haze weather and endanger human health.

Burning straw has serious environmental pollution, mainly reflected in the fact that the straw can not be fully burned during the incineration process, which produces a large amount of smoke, which only causes pollution to the environment for a period of time, and with the natural purification ability, such pollution will gradually decrease.

Straw burning is concentrated in the summer harvest and autumn harvest season, a large amount of straw burning in a short period of time will have a large amount of carbon dioxide and smoke, will have a greater impact on air quality and traffic safety, these years of burning ban work has achieved initial results, but the impact of straw returning to the field on crops is also problematic. In the future, the comprehensive utilization of straw is still a big problem, and if a large amount of straw is used well, it will produce huge economic benefits.

Burning straw is not the root cause of environmental pollution, although it also has an impact on the environment, just like burning fire for cooking or heating in ancient times, it is all burned straw and the like, and the sky is still clear.

Straw burning refers to the act of destroying crop straw by burning it. Straw burning causes smog and produces a large number of toxic and harmful substances, which poses a threat to the health of people and other organisms.

There are some reasons for environmental pollution and straw burning, which can also be regarded as serious, and some people think that it is wrong because they don't understand it. In the past, there was no need for a combine harvester, and the straw was not burned in the field, but dried and then burned in bundles. In this way, the toxic ingredients are very small, and the air pollution is not large.

However, when the straw that cannot be bundled up is burned directly in the field, the unpleasant smell of steam and a large amount of dust dragged up by the damp vapor are quite polluted.

The treatment of coal-fired orange poles is the pollution they create, and there should be no haze after the treatment, but now the haze has not decreased, but it is bigger, and it cannot pollute others, but it is the exhaust of fuel vehicles.

Straw burning only produces carbon dioxide, and it is sulfur dioxide that pollutes the environment.

It did have a great impact, Wuchang burned straw for a day, and Harbin was immediately heavily polluted, with visibility of less than 30 meters.

There's no pollution, smoke is everywhere today, and the sky will be clear tomorrow.

It's not very clear whether burning straw pollutes the environment, but what I know clearly is that it is called natural recycling, waste utilization, and is a renewable resource. Burning coal, oil, gas, and heating power is not recyclable!

Those who say that it has been burned for thousands of years, to correct it: it used to be burned as firewood, and it has been burning in the fields for nearly 30 years. The impact of burning stubble on the air is short-lived, but the impact is very obvious.

Especially on a large scale, smog days will cause a serious drop in air quality and a longer duration of haze.

When the season comes, it burns in pieces, or even across provinces, do you say that the pollution is serious? If you don't let the people who want to burn be unwilling, now it's whose interests are moved and who has opinions, now the production and lifestyle have changed so much, and the habits of many years are not changed, and they all say that they are not polluting and are not in the way, isn't this a lie with their eyes open?

No! One rain is completely pollution-free!There's no need to struggle with this!

The main source of air pollution comes from industrial pollution, don't take agriculture to blame, the mixed air was very good before the reform and opening up, isn't it also coal burning for cooking?

Experts only see straw pollution.

Who proposed the "five big" hazards of burning straw in rural areas? What is the scientific basis for this?

Excuse me, how did Tang Minghuang control environmental pollution and soil erosion?

Although straw burning has been around for thousands of years, that doesn't mean it doesn't pollute the environment. In fact, straw burning produces a large number of harmful gases and particulate matter, which have varying degrees of impact on air and soil quality.

For example, straw burning produces large amounts of harmful gases such as carbon dioxide, carbon monoxide, benzene, xylene, and volatile organic compounds, which are not only harmful to human health, but also pollute the atmospheric environment. At the same time, straw burning will also produce a large amount of dust, particulate matter and polycyclic aromatic hydrocarbons and other harmful substances, which will also cause varying degrees of pollution to the soil and water bodies.

Therefore, in order to protect the environment and human health, reduce straw burning on the environment.

Straw burning is indeed a long-standing agricultural habit, but it should be noted that there is a certain relationship between straw burning and environmental pollution. While straw burning itself may not immediately cause significant pollution to the environment, large-scale straw burning has had some negative effects on the environment over a long period of time, especially when the incineration process is uncontrolled or when large quantities of straw are burned at the same time.

Here are some of the possible environmental impacts of straw burning:

Air pollution: Straw burning releases large amounts of particulate matter and harmful gases, such as carbon dioxide, sulphur dioxide, nitrogen oxides and carbon monoxide. These pollutants can negatively affect air quality and can be harmful to human health.

Declining soil quality: Large-scale straw burning can lead to the loss of organic matter from the soil, which reduces soil fertility and water retention capacity. In addition, the ash produced during the incineration process may contain harmful substances that can negatively affect soil quality.

Loss of biodiversity: Burning straw destroys biodiversity, especially on small organisms and insects that inhabit straw. This can adversely affect the balance and function of the ecosystem.

In order to reduce the negative impact of straw burning on the environment, many places have taken measures to promote and advocate the comprehensive use of straw, such as straw returning to the field, biomass energy utilization and straw composting. These methods help to reduce pollutant emissions from combustion and improve the efficiency of straw use, thereby protecting the environment and promoting sustainable agricultural development.

Burning straw will produce air pollution, which will have a certain impact on the environment and human health. Although farmers in ancient times might have burned straw, at that time, the population density was low, the level of industrialization was low, the air quality was relatively good, and the pollutants produced by straw burning were also carried and dispersed by the natural environment, and the impact on the environment was limited. However, in modern society, with the increase of population and the advancement of industrialization, the air pollution caused by straw burning has become an important problem for the environment and human health.

Therefore, modern society should adopt a more scientific approach to the treatment and use of straw to reduce its impact on the environment.

Some data show that when straw is burned, the pollution index of sulfur dioxide, nitrogen dioxide and inhalable particulate matter in the atmosphere reaches a high peak, of which the concentration of sulfur dioxide is 1 times higher than usual, and the concentration of nitrogen dioxide and inhalable particulate matter is 3 times higher than usual, which is equivalent to the five-level level of the average daily concentration.

Straw, also known as grass straw grass in ancient times, refers to the remaining stems and leaves of rice, wheat, corn and other gramineous crops after maturity and threshing, among which the straw of rice is often called straw and rice straw, and the straw of wheat is called wheat straw.

Before industrialization, farmers used straw in a variety of ways and were very rich. For example, in southern China, people dry rice stalks and store them for firewood, weaving seat cushions, mattress stalls, brooms and other household items, laying livestock pens, feeding livestock, piling up manure and returning it to the field, and even making the roofs of simple houses, which are rarely wasted.

In the past 20 years, due to the popularization of coal, electricity, natural gas, and the abundance of various industrial products, the demand for straw in rural areas has decreased, and the disposal of a large amount of straw has become a serious social problem.

Pollution from burning straw is also a problem in Taiwan, and it has always sparked resentment, with the EPA noting that burying straw immediately at harvest time not only does not pollute the air, but is also a better way to fertilize.

What do you think of the act of burning straw? How polluting is this behavior?

Some people say that China is a big agricultural country, and the burning of straw may have a history of thousands of years, and I have never seen any great harm to the environment. At present, the rapid development of social industry, the mass production of automobiles, and the air pollution have become very serious. It can be said that the history of thousands of years is not worth the severity of air pollution in just a few decades.

If this is combined with the indiscriminate burning of straw, it will make the pollution even worse. Why?

First, the area of burning straw is large and the quantity is large. Almost all the country will produce straw, the amount is huge, and now the straw is used for other purposes less, the simplest and most labor-saving and effective way is to burn and return to the field. If there is no ban, at the same time, everyone will not be able to see the light of day again.

2. What kind of harmful substances will be produced after straw burning? We all know that after the combustion of ordinary objects, the most produced is carbon dioxide, and carbon dioxide has a certain proportion in the air. Moreover, the burning of straw is usually not sufficient, it will produce a large amount of smoke, release a large amount of carbon dioxide at the same time, but also produce a large number of solid fine particles, these fine particles float in the air, can not be eliminated for a long time, inhalation of the human body is harmful.

Another point is that burning straw in the wild is also easy to cause forest fires. The amount of straw is large and the burned area is large, and under normal circumstances, the person who burns it will not wait until the straw is all extinguished before leaving, and the fire may spread, causing a fire.

Therefore, it is still necessary to ban the burning of straw. As for how many farmers have been punished, so far we have not had many farmers punished for burning straw. If this is the case, law enforcement officials are also focused on stopping education.

After receiving the corresponding education, the farmers gradually became conscious and realized that they could not burn straw.

It is no longer possible to determine which expert proposed the ban on burning straw to pollute the environment.

Burning straw in the open not only pollutes the air, but also makes it easy for fires to break out when the wind blows, causing serious consequences. Moreover, burning straw in the field accompanied the field through high temperatures, which destroyed a lot of organic matter and burned the field to potholes.

Hazards of mass stubble burning:

1. Pollute the air and endanger human health.

The incineration process produces a large amount of carbon dioxide, nitrogen dioxide and inhalable particulate matter, which can easily cause coughing, chest tightness, and even bronchitis in severe cases after reaching a certain concentration.

2. Cause a fire.

In spring and autumn, the weather is dry and dry, and there are many combustibles in the field, and once the straw is burned, it is easy to cause disasters and threaten the safety of the village.

3. Threaten road safety.

Many farmlands are on both sides of the road, and the burning of straw produces a lot of smoke, which reduces air visibility and is prone to traffic accidents.

4. Destroy the soil and reduce the quality of farmland.

In the process of straw burning, the opportunity and nitrogen nutrients of straw are lost, and the potassium and phosphorus left behind are difficult to be absorbed by crops, resulting in land clumping. <>

For many years, the issue that had the greatest impact on farmers was the disposal of straw. The state prohibits farmers from burning straw for environmental governance and safe production, which creates a natural conflict with farmers burning straw to protect their own interests. Experts believe that straw burning is too harmful, affecting traffic, causing fire hazards, and is the main culprit of air quality pollution such as haze.

Every year, a large number of village cadres and other personnel are organized to conduct strict inspections on straw burning.

When wheat is harvested, the straw is directly broken and returned to the field, which can not only reduce the pollution of burning straw to the atmosphere, but also increase the organic matter of the land and enhance the fertility of the land. Nowadays, eco-friendly power plants are built in many places, and these eco-friendly power plants can generate electricity not only from household waste, but also from crop straw.
