What is sand and dust weather?

Sand and dust weather refers to strong winds rolling up a large amount of dust and sand from the ground, making the air turbid and horizontal. A weather phenomenon in which visibility is significantly reduced.

Sandy weather is divided into three categories: floating dust, blowing sand, and sandstorms.

Floating dust: Sand or soil particles evenly suspended in the atmosphere (mostly from other places, or left in the air after local blowing sand or sandstorms), making horizontal visibility less than 10 kilometers.

Blowing sand: The wind blows up the dust and sand on the ground, making the air quite turbid, and the horizontal visibility is within 1 to 10 kilometers.

Sandstorm: Strong winds blow up dust and sand on the ground, making the air very turbid and horizontal visibility less than 1 km. When the horizontal visibility is less than 500 meters, it is defined as a strong sandstorm.

Pollution and Hazards of Waste Batteries

Pollution and Hazards of Waste Batteries Button Batteries Button batteries contain mercury. When they are discarded in nature and the outer metal corrodes, the mercury will It will slowly overflow from the battery, enter the soil or enter the groundwater after rain, and then enter the human body through crops, damaging human internal organs. Under the action of microorganisms, inorganic mercury can be converted into methylmercury, which accumulates in the body of fish. After people eat this kind of fish, methylmercury will enter the human brain cells, causing serious damage to the human nervous system and seriously damaging the human nervous system. The person will go crazy and die. Minamata disease in Japan is caused by methylmercury.

Rechargeable batteries Rechargeable batteries generally contain harmful heavy metal cadmium. After seeping out in nature, it pollutes the land and water flows and eventually enters the human body. Cadmium can cause osteoporosis, bone deformation, bone pain, liver and kidney damage and other serious consequences.

Ordinary batteries Ordinary dry batteries also contain mercury, lead and acids and bases, which are also very harmful to the environment. Therefore, in developed countries, used batteries are classified as hazardous and toxic waste and must be placed and recycled separately, and must not be discarded casually in nature. In Germany, used batteries can be sent to every store that sells batteries. This is something we can learn from.

For the future of the earth, we must work hard from now on to protect the environment. Here we make the following suggestions:

Implement garbage classification and bagging. This will not only reduce The workload of sanitation workers can also better utilize waste, reduce pollution, and save resources.

When buying food, use less plastic bags and try to use bamboo baskets.

Try to use refillable pens to reduce the waste of ballpoint pen shells and the amount of garbage.

Try not to use disposable lunch boxes when eating out.

Sowing green means sowing hope. Excessive garbage and environmental problems Recycling of garbage and comprehensive utilization of resources Recycling of garbage and comprehensive utilization of resources (Part 2) Science in the sea bath

Think of it from drinking pure water

Tips on environmental protection

1. According to surveys, 700 million people in my country drink water with excessive E. coli bacteria, 164 million people drink water with serious organic pollution, and 35 million people drink water with excessive nitrate.

2. Buy environmentally friendly batteries to prevent mercury and cadmium pollution. Batteries in daily use contain large amounts of heavy metal contaminants - cadmium, mercury, manganese, etc. When discarded in nature, these toxic substances slowly overflow from the battery, enter the soil or water sources, and then enter the human food chain through crops. These toxic substances will accumulate in the human body for a long time and are difficult to eliminate, damaging the nervous system, hematopoietic function, kidneys and bones, and some can even cause cancer.

3. The ozone over Antarctica is thinning at a rate of 1% per day, and the hole is as large as Europe. According to relevant research by the U.S. Environmental Protection Agency, for every 1% reduction in ozone content in the atmosphere, there will be an increase of 100,000 skin cancer patients, as well as an increase in the number of people suffering from cataracts and respiratory diseases.

4. A tree that has grown for 50 years can produce oxygen worth US$31,250 and protein worth US$2,600 every year through photosynthesis. It can also prevent air pollution (US$62,500) and conserve water sources. , promote water recirculation ($37,500), prevent soil erosion, increase soil fertility ($31,250), and provide habitat for birds and other animals ($32,150). Calculating these combined values ??together, this tree can be used every year The value should be $200,000.

5. In the age of dinosaurs, one animal became extinct on average every 1,000 years; before the 20th century, one animal became extinct on the earth about every four years; now about 40,000 species become extinct every year. In the past 150 years, 80 species of birds have become extinct; in the past 50 years, nearly 40 species of mammals have become extinct. In the past 100 years, the rate of species extinction has exceeded 1,000 times its natural extinction rate, and this rate is still increasing.

6. At present, the global desertification area has reached 36 million square kilometers, accounting for 1/4 of the entire earth's land area. About 900 million people are affected and threatened by desertification.

7. The "Wildlife Protection Law of the People's Republic of China" stipulates that it is prohibited to sell or purchase nationally protected wild animals or products.

The Ministry of Commerce stipulates that acquisitions and any form of buying and selling of countries are prohibited

II. my country's environmental conditions

1. Air pollution is soot-type pollution, with dust and acid rain causing the greatest harm, and the degree of pollution is intensifying.

2. Acid rain is mainly distributed in the south of the Yangtze River, the east of the Qinghai-Tibet Plateau and the Sichuan Basin. Central China is the most polluted by acid rain.

3. The waters of rivers, lakes and reservoirs are generally polluted to varying degrees. Except for some inland rivers and large reservoirs, pollution has become more and more serious. The pollution of waters near industrially developed towns is particularly prominent.

4. Among the seven major river systems (Pearl River, Yangtze River, Yellow River, Huaihe River, Hailuan River, Liaohe River, and Songhua River), the water pollution in the Yellow River Basin, Songhua River, and Liaohe River Basin is serious.

5. Large freshwater lakes have widespread total phosphorus and total nitrogen pollution, and are seriously eutrophication.

6. Among the four sea areas, the Bohai Sea and the East China Sea are more polluted, while the South China Sea is less polluted.

7. The deterioration of the ecological environment in fishery waters has not fundamentally changed and is showing an increasing trend.

8. Urban environmental pollution is increasing.

9. Urban surface water pollution is generally serious and is getting worse. Most rivers are polluted to varying degrees.

10. Two-thirds of the country’s rivers and more than 10 million hectares of farmland are polluted.

Environmental pollution has various classifications:

< p>According to environmental factors: air pollution, water pollution, soil pollution.

According to human activities: industrial environmental pollution, urban environmental pollution, agricultural environmental pollution.

According to the nature and source of environmental pollution: chemical pollution, biological pollution, physical pollution (noise pollution, radioactivity, electromagnetic waves), solid waste pollution, and energy pollution.

Environmental pollution will cause direct damage and impact to the ecosystem, such as desertification and forest destruction, and it will also cause indirect harm to the ecosystem and human society. Sometimes the harm of this indirect environmental effect is greater than that of the The direct harm caused is greater and more difficult to eliminate. For example, the greenhouse effect, acid rain, and ozone layer depletion are environmental effects derived from air pollution. This kind of environmental effect derived from environmental pollution has a hysteretic nature and is often not easily noticed or expected when the pollution occurs. However, once it occurs, it means that the environmental pollution has developed to a quite serious level. Of course, the most direct and easily felt consequence of environmental pollution is the degradation of the quality of the human environment, affecting human quality of life, health and production activities. For example, urban air pollution causes air pollution and increases people's morbidity rates; water pollution worsens the quality of the water environment and generally reduces the quality of drinking water sources, threatening people's health and causing premature birth or malformation of fetuses. Serious pollution incidents not only bring health problems, but also cause social problems. With the intensification of pollution and the improvement of people's environmental awareness, disputes and conflicts among people caused by pollution are increasing year by year.

At present, environmental pollution problems have occurred to varying degrees around the world. Aspects with global impact include atmospheric environmental pollution, ocean pollution, urban environmental problems, etc. With the globalization of economy and trade, environmental pollution has increasingly shown an international trend. The problem of transboundary transfer of hazardous wastes that has emerged in recent years is a prominent manifestation in this regard.

Protecting the earth starts with me

Throughout the ages, Mother Earth has nurtured countless generations of descendants with her sweet milk. It turns out that she was beautifully decorated by the juniors. However, now humans torture her to the point of darkness for their own benefit. Humanity has only one earth; and the earth is facing a severe environmental crisis. "Save the earth" has become the strongest voice of people all over the world.

I feel heartbroken by the deterioration of the surrounding environment. I think: as the future successors, if young people do not understand the composition of the human environment and the seriousness of environmental problems, and ignore the laws and regulations related to environmental protection, they will not be able to If we strengthen our awareness of environmental protection and consciously fulfill our obligations to protect the environment, our lives will be destroyed in our own hands, and God will severely punish us. For this reason, I made up my mind to start from myself, protect the environment, protect our homeland, and be a guardian of the environment.
