But others don't think so. Xiao Ming said, "It won't do any harm to throw away the waste batteries. You see, there is no harm in so many people throwing it around! " I have an opinion on this issue. In fact, littering waste batteries is very harmful. If a small piece of button cell is thrown or buried underground, it will destroy 600 square meters of ground, and a section of 1 battery is buried underground, then this land is worth using.
Therefore, we can't throw away the battery because it is very harmful. When a small battery is thrown into the water, it pollutes 60 square meters of water, which is the amount of water that a person drinks in his life.
This is a big number. Batteries are a big killer of human beings. Waste batteries contain many things, which are particularly bad for human body. If things in the battery pollute the air, as soon as you breathe, those things will enter your body through your nose or mouth, so you will get many unexplained strange diseases and then die slowly.
Let's protect the environment and join in the classified recycling of used batteries. It is also a civilization not to throw away used batteries. Let's protect the beautiful mountains and rivers of our motherland, cherish the earth we live in and live in a better global village.
2. What are the hazards of the battery? It is urgent. I want to write a composition. If a 1 battery rot in the ground, its toxic substances can make one square meter of land lose its use value; Throw a grain of button cell into the water, and the toxic substances it contains will pollute 600,000 liters of water, which is equivalent to a person's lifetime water consumption; Waste batteries contain heavy metals such as cadmium, lead, mercury, nickel, zinc and manganese, among which cadmium, lead and mercury are harmful to human body.
However, although metals such as nickel and zinc are beneficial substances in a certain concentration range, exceeding the limit in the environment will also cause harm to the human body. Heavy metals in waste batteries will affect the germination and growth of seeds.
Heavy metals oozing from waste batteries will pollute rivers, lakes, oceans and other water bodies, endanger the survival of aquatic organisms and the utilization of water resources, and indirectly threaten human health. Waste acid, waste alkali and other electrolyte solutions may pollute the land, acidifying and salinizing the land, just like a time bomb buried around us.
Therefore, the collection and disposal of waste batteries is very important. If it is not handled properly, it may cause serious harm to the ecological environment and human health. Discarding waste batteries at will not only pollutes the environment, but also wastes resources.
Someone has calculated an account. Based on the annual production of 654.38+000 billion batteries in China, the annual consumption is 654.38+056 million tons of zinc, 226,000 tons of manganese dioxide, 2080 tons of copper, 27,000 tons of zinc chloride, 79,000 tons of ammonium chloride and 43,000 tons of carbon rods. Although advanced technology has given us the right direction, the battery pollution situation in China is still not optimistic.
At present, most of the waste batteries in China are mixed with domestic garbage and buried underground. Over time, after transformation, the batteries rot and heavy metals dissolve, which may pollute groundwater and soil and eventually enter the human food chain through various channels. Heavy metals ingested by organisms from the environment are gradually enriched thousands of times in higher organisms through the biomagnification of the food chain, and then enter the human body through the food chain and accumulate in some organs, leading to chronic poisoning. Minamata disease in Japan is a typical case of mercury poisoning.
With the continuous development of science and technology and the continuous improvement of people's living standards, the use of batteries has become an indispensable part of our daily life.
However, the battery can be said to be how much it is produced and how much it will eventually be discarded; Concentrate production and disperse pollution. Nowadays, the harm of waste batteries has become an environmental problem that people all over the world pay close attention to.
Countries all over the world are studying the best scheme to deal with waste batteries. Although fruitful results have been achieved, this problem cannot be fundamentally solved.
Therefore, finding the best solution to deal with waste batteries has become the research direction of many scientists in various countries. Waste batteries look unremarkable, but they are actually very harmful.
I looked up a lot of information on the internet and learned that the batteries people use every day rely on chemical action, or in layman's terms, corrosion to generate electricity. The battery contains metal substances such as mercury, cadmium and aluminum, and mercury is very toxic. Cadmium mainly causes kidney injury and bone diseases-osteoporosis, rickets and fractures.
Lead can cause neurological disorders and nephritis. One section of button cell can pollute 600,000 liters of water, and one section of No.1 battery can make one square meter of land lose its use value in the soil. It can be seen that the harm of waste batteries is very great, and recycling is imperative.
But waste batteries are not only harmful to human beings, but also contain many resources. For example, button cell contains rare metals such as lithium, manganese and silver; Lead storage batteries contain lead; Mobile phone batteries contain cadmium and have high recycling value.
At present, some factories have begun to recycle and extract in this respect. In addition, ordinary dry batteries also contain resources such as zinc, copper and manganese powder.
With the improvement of living standards, the number of electrical appliances using batteries has gradually increased, and the number of used batteries has also increased a lot. In order to avoid this harm to human beings, when we throw garbage, we should throw the battery away from other garbage.
This can not only recycle these waste batteries, but also extract resources without polluting the soil and protecting human health. Isn't this killing two birds with one stone? Let's start from scratch, care for the environment, care for ourselves, and participate in the recycling of used batteries. This is the responsibility and obligation of every caring person. Shouldn't we do better in this action of protecting the earth's homeland, protecting the living environment of human beings and protecting our own health? .
4. What are the hazards of the battery? I think everyone is familiar with it. Although he is small and thin, he is very powerful. Put the battery in the remote control, and the remote control that doesn't listen to the command can be controlled by you immediately; Put the battery into the repeater, and the repeater will make a clear sound. . The battery is really our good helper.
Some people say, "batteries are good, but you can't throw them away casually." If littered, it will become an' invisible killer' and pollute the environment. " Some people say: "throwing batteries casually will not pollute the environment." Look, isn't everyone else littering? I don't see any pollution to the environment. "
I don't think it's right to throw batteries around. Although its volume and mass are small, it contains many kinds of metallic substances. When the battery is discarded in nature, the mercury contained in it will overflow slowly, enter the soil or water source, and then enter the human body through crops, damaging people's kidneys.
Not only that, according to relevant data, a button-sized battery can pollute 600,000 liters of water, which is equivalent to a person's drinking water for a lifetime. A rotten battery in the ground can make a square meter of land useless. Therefore, people often refer to waste batteries as' pollution bombs'. What is even more frightening is that; Mercury will be transformed into methylmercury under the action of microorganisms, and inorganic mercury will gather in fish. If people eat this fish, methylmercury will enter human brain cells, causing serious damage to people's nervous system, and even more serious, they will go crazy and die.
The battery is too harmful. Even if the environment is not polluted now and people are not hurt by batteries, what will happen later? The biggest feature of the battery is that it cannot be degraded in nature. Maybe if we throw batteries about now, our next generation will be polluted in 50 years. So we can't throw batteries about.
Let's work together to build a green tomorrow, and don't let waste destroy our home.
5. Harm of batteries How to write the harm of waste batteries Some people say that waste batteries can't be thrown around, which will seriously pollute the environment.
Individual students ignored it and said, "Don't everyone throw it around? I don't see any harm! " Many people have different views on this issue, and I also have an opinion. In my opinion, batteries should not be thrown away casually, because waste batteries are small but harmful.
As we all know, waste batteries mainly contain heavy metals such as cadmium, lead, mercury, nickel, zinc and manganese, among which cadmium, lead and mercury are harmful to human body. Waste batteries are a big killer that harms our living environment! A small button cell can pollute 600 cubic meters of water, which is equivalent to a person's lifetime drinking water; A rotten battery in the ground can make a square meter of land lose its use value and cause permanent public hazards.
In nature, mercury in waste batteries will slowly overflow from the batteries, enter the soil or water, and then enter the human body through crops, damaging the human kidneys. Under the action of microorganisms, inorganic mercury can be converted into methyl mercury, which will gather in fish. After people eat this fish, methylmercury will enter human brain cells, seriously damage people's nervous system, and even lead to madness and death.
Starting from me, starting from every little thing around us, protecting the ecological environment. Caring for the surrounding environment and participating in the classification and recycling of used batteries is the responsibility and obligation of each of us.
Protecting our earth and nature means protecting ourselves.
6. Harm of battery Battery is one of the most widely used commodities in life, such as calculators, watches, electric toys, telephones and repeaters.
Many goods are inseparable from batteries.
But when the battery is used up, it is littered everywhere, which is very harmful. Half the students in the class said it was harmless to throw away used batteries.
I found in the book "100,000 Why", "Why do used batteries kill people? Its content is roughly as follows: One winter, more than a dozen patients were found in Japan: shaking hands, stiff legs, unable to walk, crying and laughing for a while. Later, two people died and one committed suicide by throwing himself into the river.
Autopsy confirmed that it was not bacterial encephalitis, but related to excessive intake of manganese metal. It is because more than 300 recycled batteries are buried in the well that the problem lies in this waste battery.
Waste batteries are buried in the soil, and the manganese inside is exposed after the shell decays. When it meets carbon monoxide, it is converted into water-soluble bicarbonate, which seeps into the well with groundwater, making the drinker manganese poisoned. But after I showed this information to some students who said it was harmless, they still said it was harmless to throw waste batteries.
But I think this is very harmful, because from this information, we can see that throwing waste batteries will lead to some deaths. This warns people: waste batteries must not be thrown around casually, but should be treated centrally.
7. electromagnetic pollution essay electromagnetic pollution 1. What is electromagnetic pollution?
Alternating changes of electric and magnetic fields produce electromagnetic waves. The phenomenon that electromagnetic waves are emitted into the air or in flood season is called electromagnetic radiation. Excessive electromagnetic radiation causes electromagnetic pollution. Electromagnetic pollution refers to natural and man-made electromagnetic interference and harmful electromagnetic radiation. Due to the development of radio, television and microwave technology, the power of RF equipment has doubled, and the electromagnetic radiation on the ground has greatly increased, which has directly threatened human health.
Electromagnetic pollution includes natural and man-made sources.
Electromagnetic pollution affecting human living environment can be divided into two categories: natural electromagnetic pollution and man-made electromagnetic pollution.
Natural electromagnetic pollution is caused by some natural phenomena. The most common is lightning, which may not only cause direct damage to electrical equipment, aircraft, buildings and so on. But also cause serious electromagnetic interference in a wide range of frequencies from several kilohertz to several hundred megahertz. Volcanic eruptions, earthquakes and magnetic explosions caused by sunspot activities can all cause electromagnetic interference. The interference of natural electromagnetic pollution to short-wave communication is extremely serious.
Man-made electromagnetic pollution includes: ① pulse discharge. For example, when a high-current circuit is cut off, spark discharge has a large transient current, which will produce strong electromagnetism. It is essentially the same as lightning, but the affected area is smaller. ② Power frequency alternating electromagnetic field. For example, the electromagnetic fields near high-power motors, transformers and transmission lines do not radiate outward in the form of electromagnetic waves, but will cause serious electromagnetic interference in the near field. ③ Radio frequency electromagnetic radiation. Such as radio broadcasting, television and microwave communication. , wide frequency range, large influence area, which can cause harm to near-field staff. At present, radio frequency electromagnetic radiation has become the main factor of environmental electromagnetic pollution.
Second, where is the place where electromagnetic radiation is easy to exceed the standard?
(1) within 0.6- 1.5m of the computer.
(2) TV sets, stereos and other household appliances are relatively concentrated in the living room.
(3) Industrial, scientific and medical electrical equipment and around VDT
(4) Around the radio and television transmission tower
(5) Around various microwave towers
(6) Around the radar
(7) Lines and equipment around the high-voltage substation.
Third, the harm of electromagnetic pollution to human body
1. Electromagnetic radiation is the main cause of cardiovascular disease, diabetes and cancer mutation.
2. Electromagnetic radiation causes direct damage to human reproductive system, nervous system and immune system.
3. Electromagnetic radiation is the inducing factor of abortion, infertility, teratoma and other diseases.
4. Excessive electromagnetic radiation directly affects brain tissue development, bone marrow development and vision loss; Liver disease, decreased hematopoietic function, severe punishment will lead to retinal detachment.
5, electromagnetic radiation can make male sexual function decline, female endocrine disorders, menstrual disorders.
Fourth, protection suggestions.
1. The elderly, children and pregnant women belong to the sensitive population of electromagnetic radiation. When they are active in the environment with electromagnetic radiation, they should choose appropriate protective clothing for protection according to the characteristics of radiation frequency or field strength. It is suggested that pregnant women should be protected in all directions during pregnancy, especially in the first trimester, and they should not be lucky about the harm of electromagnetic radiation.
2, usually pay attention to understand the relevant knowledge of electromagnetic radiation, enhance awareness of prevention, understand the relevant national laws and regulations, and protect their health and safety from infringement.
The radio and television effects we encounter in our daily life suddenly deteriorate, almost all of which are caused by electromagnetic interference.
3, don't put the household appliances too concentrated, so as not to expose yourself to the danger of excessive radiation. Especially some household appliances that are easy to generate electromagnetic waves, such as radios, televisions, computers, refrigerators, etc. , should not be placed in the center. Use electrical equipment reasonably, keep a safe distance and reduce radiation hazards.
4. Pay attention to the distance between human body and office and household appliances, and keep a safe distance when using various appliances. For example, the distance between TV and people should be 4~5 m, the distance between TV and fluorescent lamp should be 2 ~ 3 m, and the microwave oven should leave at least 1m after turning on, and pregnant women and children should stay away from the microwave oven as far as possible.
5, all kinds of household appliances, office equipment, mobile phones, etc. Long-term operation should be avoided as far as possible, and various office and household appliances should be avoided as far as possible. The electromagnetic radiation released at the moment when the mobile phone is turned on is the largest. When using, the distance between the head and the antenna of the mobile phone should be as far as possible, and it is best to use a separate earphone and microphone to answer the phone.
6, diet attention to eat more foods rich in vitamin A, vitamin C and protein, enhance the body's ability to resist electromagnetic radiation. Usually pay attention to the knowledge of electromagnetic radiation, enhance the awareness of prevention, understand the relevant laws and regulations of the state, and protect their health and safety from infringement.
With the continuous development of science and technology and the continuous improvement of people's living standards, the use of batteries has become an indispensable part of our daily life.

9. What are the hazards of battery composition? If so, please ask the scholars to ask questions quickly: Class 5, Class 2, Grade 4, please click "Satisfied Adoption" after reading the composition, which is a respect for others' labor! It is not easy to answer questions, and look and adopt them! Some people say, "waste batteries should not be thrown about, which will pollute the environment."
But others don't think so. Xiao Ming said, "It won't do any harm to throw away the waste batteries. You see, there is no harm in so many people throwing it around! " I have an opinion on this issue.
