Ask for an essay in english about the dangers of waste batteries and make suggestions 20

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, it can be said that as much as the battery is produced, it will eventually be discarded; Centralized production, dispersed pollution. Nowadays, the harm of waste batteries has become an environmental concern for people all over the world.

Countries around the world are researching the best way to dispose of waste batteries. Although fruitful results have been achieved, the problem cannot be fundamentally solved. Therefore, finding the best solution to dispose of waste batteries has become the scientific research direction of many scientists in various countries.

Waste batteries may seem inconspicuous, but they can be very harmful. I have looked up a lot of information on the Internet and learned that the batteries that people use daily rely on chemical action, and generally speaking, they rely on corrosion to produce electricity.

The battery contains mercury, cadmium, aluminum and other metal substances, and mercury is highly toxic; Cadmium is responsible for kidney damage and bone diseases such as osteoporosis, hypochondria, and fractures. Lead can cause nervous disorders, nephritis, etc. A button battery can pollute 600,000 liters of water, and a No. 1 battery in the soil can make a square meter of land lose its use value, it can be seen that the harm of waste batteries is very great, so it is imperative to waste batteries.

But waste batteries are not just harmful to humans, they contain a lot of resources. For example, coin cell batteries contain rare metals such as lithium, manganese, and silver; Lead-acid batteries contain lead; Mobile phone batteries contain cadmium, which is highly valuable. Some factories have begun to carry out this work of extraction.

In addition, ordinary dry batteries also contain zinc, copper, manganese powder and other resources. With the improvement of life, the number of electrical appliances we use batteries has gradually increased, and the number of waste batteries has also increased a lot. In order to avoid this harm to human beings, when we throw away garbage, we should dispose of batteries separately from other garbage.

In this way, these waste batteries can extract resources without polluting the soil, and can also protect human health. Let's start from bit by bit, care for the environment, take care of ourselves, and participate in the use of waste batteries is the responsibility and obligation of each of us who cares. Shouldn't we do a better job in this action to protect our homeland, protect the living environment of human beings, and protect our own health?

I once saw such an imaginary article in the magazine "Mystery", to the effect that "in 2100, the world's 'garbage mountain' was continuous, emitting bursts of unpleasant stench, and people wore 'anti-poison' masks for a long time, which brought great inconvenience to people's clothing, food, housing, and transportation....Although the article has a satirical flavor, it is aimed at 'today's garbage siege problem has sounded the alarm for mankind, and it is urgent to deal with garbage scientifically!'

Nowadays, with the improvement of living standards, people's waste is also more and more, according to statistics, each person discards kilograms of garbage every day, and domestic garbage grows at a rate of 6% every year. Paper, fruit and vegetable husks, glass, scrap metal electrical appliances have become domestic garbage after scrapping, especially all kinds of food packaging bags, disposable lunch boxes, plastic bags and other plastic waste has become a worldwide environmental hazard, general plastic products in nature, it takes 200-400 years to be completely decomposed, if it is buried in the soil will affect the growth of crops, by livestock will be eaten by mistake will endanger their health, if incineration will release a large number of toxic gases, endanger human health. There are also waste batteries are also quite harmful, a button-sized battery, once its toxic substances dive into the water, will pollute 600 cubic meters of water, and endanger the survival of aquatic animals and plants.

Garbage is so harmful, what should we do with it? Maybe some students will think that "garbage generally goes into the garbage dump, there are uncles and aunts in the field to deal with it, and it has nothing to do with me", in fact, building a clean and beautiful environment is the responsibility of each of us, we are small citizens of the society, we can also make a contribution to the scientific treatment of garbage.

First of all, we can "reduce" the production of garbage. We should refuse to use unnecessary disposable fast food boxes, plastic bags and other plastic products, and try to use green packaging such as cartons and reusable cloth bags. We should also save paper and reduce paper costs.

In addition, we can also sort **garbage. We can set up three different colors of garbage bins, which contain garbage: food waste, ordinary garbage, and hazardous garbage.

In this way, we can provide convenience for the disposal of garbage, especially hazardous garbage such as batteries, we can make it not mixed with ordinary garbage through the first method, and be removed and disposed of separately. In order to better ** the battery, I suggest that the school set up a "waste battery ** station", which can be carried out by conversion, such as 10 waste No. 5 batteries can be exchanged for 4 new No. 5 batteries.

I believe that through the school's vigorous publicity and environmental protection activities, and through the active efforts of students, our school and our country will be free from the problem of garbage. Science ** garbage starts from me, from now on, let's take action to make our motherland more beautiful, let our children be healthier, and make our people happier.

1. There are many functions of batteries, toys, laptops, cameras, etc., batteries are needed, batteries bring a lot of convenience to our lives, and make our lives more colorful. However, if we litter the waste batteries, it will harm the soil and water sources, making us and the living environment worse and worse.

There are many people who litter batteries, they think that the battery is small in size and will not cause great pollution to the environment, but they don't know that waste batteries contain mercury, cadmium, lead, zinc and other heavy metal harmful substances. Within one month of the waste battery being landfilled in the soil, its metal shell will be corroded and perforated, and the harmful substances in the waste battery will enter the soil and water, causing pollution to the environment and ultimately affecting our human health.

In my opinion, casual waste batteries will not only cause some pollution to the environment, but also a waste of resources. For the health of our human beings and Mother Earth, in our daily life, we should raise the awareness of environmental protection, classify waste batteries, and let them be used rationally again.

Let's join hands and be the little sanitation of the earth together!

2Students, do you know the dangers of every waste battery? But someone said, "What can such a small thing be so great for the earth!"

Besides, some people throw away waste batteries every day and don't see how harmful they are. "Although the battery may not seem so destructive, you can't look at everything at the surface, as the saying goes, "You can't look at people, and you can't fight in the sea."

Within one month of landfilling, the metal shell of the waste battery will be corroded and perforated, and the harmful substances in the waste battery will enter the soil and water, causing pollution to the environment. If there is a mercury-containing battery in 6 tonnes of garbage, the mercury in the soil will exceed the safe standard when the waste is landfilled; If waste batteries are mixed with domestic garbage and enter the incineration plant, the atmosphere will be polluted and human health will be affected. Metals such as mercury and cadmium will produce harmful substances.

However, under normal use, mercury and cadmium in the battery do not leach out.

Therefore, in my opinion, as long as the battery is used normally, the harm of the battery to the human body is not too great; If used batteries do go into the incineration plant or bury them in the ground, I can't imagine the consequences. But be careful, it will endanger the children and grandchildren of the destroyers of the earth; It will endanger the children and grandchildren of the protectors of the planet.

Students, protect the natural ecology; Take care of the planet we live on! Don't let used batteries pollute the earth; Don't let used batteries pollute our homes! Protecting the environment starts with me; Don't litter, start with yourself!

Batteries contain mercury, lead, cadmium and other kinds, if waste batteries are mixed with domestic garbage to landfill, or discarded, the leached mercury and heavy metal substances will penetrate into the soil, pollute groundwater, and then enter fish and crops, destroy the living environment of human beings, and indirectly threaten human health.

The biggest feature of heavy metal pollution is that it cannot be degraded in nature!

Long-term consumption of water and food contaminated with cadmium can lead to bone pain, cadmium enters the human body, causing bone softening and bone deformation, and in severe cases, natural fractures are formed, resulting in death!

Lead mainly acts on the nervous system, hematopoietic system, digestive system, liver, kidney and other organs, can inhibit the anabolism of hemoglobin, and can also directly act on mature red blood cells! Therefore, it is not too much to turn waste batteries into "pollution bombs".

Start with me, from every little thing around you.

To protect our planet is to protect ourselves!

Messy battery hazards.

Small battery harm, environmental pollution is afraid, the family collects waste electricity and sends it to the battery station, which not only beautifies the environment but also protects the ecology.

The harm of waste batteries is not something that can be seen immediately at home, just like smoking cigarettes, and it can only be disadvantaged by the intermittent length, and it is often accumulated over time, and it is too late to see the harm. Radio, watch, remote control, alarm clock ...... used in daily lifeInseparable from batteries, there is information that waste batteries contain a lot of heavy metals, even if you eat a little of them, you may suffer from anemia, and may also cause kidney damage, serious and even cancer. If the waste battery is thrown into the soil, it will cause the square meter of soil to lose its value and not grow crops; Throwing it into the water is worse than you think, it will pollute a lot of water, animals will die or even become extinct, species will have no drinking water because of it, and the air will be polluted ......There are so many hazards that we usually don't pay attention to, so waste batteries should never be littered everywhere.

It is said: 'Littering batteries is not harmful', and I feel that the sentence is both wrong and irresponsible. The diseases and environmental pollution caused by battery hazards are unimaginable, and the TV often popularizes the knowledge of education, not only to start yourself, but also to help those who do not understand the harm.

Waste batteries can be collected door-to-door and sent to special waste battery stations. You can also instill in him some knowledge, and he will understand the truth. Start around, start from the side, start to collect waste batteries, and change the environmental protection of the global village.

According to relevant information, batteries contain a large number of heavy metals, such as zinc, lead, cadmium, mercury, manganese, etc. According to expert tests, a single button battery can pollute 600 cubic meters of water.

A No. 1 battery rots in the ground, which can make one square meter of land lose its use value. Look at it, the harm of messing with a battery is so great!If the waste battery is mixed with domestic garbage, after the battery decays, the dissolution of heavy metals such as mercury, cadmium, lead, nickel and so on will pollute the groundwater and soil, and then penetrate into the fish and crops, destroying the living environment of human beings and threatening human health.

If a person is poisoned by mercury, he will suffer from central nervous system disease, and the mortality rate is as high as 40%;Cadmium in used batteries is classified as a carcinogen. This is not alarmist!

For the environment, a small button battery can pollute 600 cubic meters of water, which is equivalent to a person's lifetime drinking waterOne dry cell can pollute 12 cubic meters of water, one cubic meter of soil, and cause permanent pollution ......For human beings: The ordinary dry batteries we use in daily life mainly include acidic zinc-manganese batteries and alkaline zinc-manganese batteries.

A single button battery can contaminate 600,000 litres of water, which is equivalent to the amount of water a person drinks in a lifetime. And China consumes 7 billion such batteries every year... A No. 1 battery rotting in the ground can make one square meter of land lose its use value and cause permanent pollution.

The "painful disease" in Japan, which shocked the world, was caused by cadmium pollution.

First, it is necessary to prevent and control from the source and promote mercury-free batteries.

On December 31, 1997, nine ministries, commissions and bureaus, including the China Light Industry Association, the former State Environmental Protection Administration, and the State Bureau of Quality and Technical Supervision, jointly promulgated the Regulations on Limiting the Mercury Content in Battery Products, requiring that the domestic production and distribution of batteries with mercury content greater than the weight of the battery be prohibited by January 1, 2002, and the domestic production and distribution of alkaline zinc-manganese batteries with mercury content greater than the weight of the battery by January 1, 2006.

Since the issuance of the "mercury restriction order" for batteries, China's battery companies have actively innovated the production process and improved the raw material formula, and the batteries produced by regular battery manufacturers have basically achieved mercury-free.

Second, the national policy does not encourage the centralized collection of waste batteries.

The former State Environmental Protection Administration, the National Development and Reform Commission, the Ministry of Construction, the Ministry of Science and Technology, the Ministry of Commerce and other five ministries and commissions jointly issued on October 9, 2003 the "Technical Policy on the Prevention and Control of Waste Battery Pollution" stipulates that at present, in the absence of effective technical and economic conditions, the centralized collection of waste disposable batteries that have met the national low or mercury-free requirements is not encouraged.

In addition, the National Hazardous Waste List jointly issued by the Ministry of Environmental Protection and the National Development and Reform Commission on June 6, 2008 stipulates that waste nickel-cadmium batteries and mercury oxide batteries generated in daily household life can be exempted from hazardous waste management.

The above provisions are the requirements of the relevant state departments and experts after scientific demonstration. Waste batteries can not be disposed of in a unified manner, and citizens can disperse waste batteries into the formal domestic garbage collection bin, and enter the city's regular domestic waste landfill together with domestic garbage, which will not cause environmental pollution.

Most of the pollutants in the commonly used dry battery are solid, and most of the harmful substances are insoluble in the battery or after being discarded in the environment, and the migration of pollutants from the inside to the environment or the diffusion in the environment is a very slow process, especially mercury. As a result, the scope and extent of its contamination is limited. As early as the early 80s, the Japan Battery Manufacturers Association commissioned Fukuoka University to conduct a 15-year study on the migration of mercury in waste batteries.

They used different landfill methods to fill waste zinc-manganese, alkaline zinc-manganese, mercury oxide and other batteries in different landfill columns, monitored the mercury content in the leachate and the air in the landfill column and the mercury concentration in the air when the landfill column disintegrated, and conducted comparative analysis, the amount of mercury migrating with the leachate in the experimental column in 10 years only accounted for the total amount of mercury, and the amount of mercury diffused through the atmosphere only accounted for the total amount of mercury. The environmental impact of mercury in used batteries that come with landfills is not as severe as some advertise.
