The pollution caused by the battery to the environment and the pollution of the environment by the b

Waste dry batteries contain a large number of heavy metals, acids, alkalis and other substances, and most of the dry batteries produced in China also contain mercury that is seriously harmful to the environment. Due to its highly toxic, accumulative, and easily migratory nature, mercury can cause long-term hazards once it enters ecosystems and is passed on from generation to generation. When used batteries are discarded or mixed in the garbage, these toxic substances will slowly spill out of the batteries, enter the soil and water sources, and finally enter the human body.

These toxic substances will accumulate in the human body for a long time, which is difficult to eliminate, damage the nervous system, hematopoietic function, kidneys and bones, and some can also cause cancer. There is information that a section of No. 5 waste dry battery can pollute organisms within 1 square meter of land; Mercury pollution from waste dry batteries accounts for 60 80 percent of mercury pollution from municipal solid waste.

All kinds of dry batteries pollute the environment, regardless of acidic alkaline charging once, relatively speaking, mercury-free and cadmium-free batteries are slightly better.

Of course, the least polluting environment is the solar cell, but the silicon wafer is plated with something, and the life is long and the most environmentally friendly.

Others, such as hydrogen-oxygen fuel cells and aluminum-air batteries, are also more environmentally friendly.

It is said that there is pollution.

Will there still be a clean one?

Our country is really weak in terms of ** batteries!!

Coin cell batteries are more polluting to the environment, which can pollute 60 cubic meters of water.

Waste batteries contain heavy metals such as mercury, lead, cadmium, nickel, and electrolyte solutions such as acids and alkalis, which are harmful to the human body and the ecological environment to varying degrees. These toxic substances enter the human body through various ways, and it is difficult to eliminate long-term accumulation, which will damage people's nervous system, hematopoietic function and bones, interfere with kidney function and reproductive function, and easily make people chronically poisoned, paralyzed, and even carcinogenic.

Batteries pollute the environment because:

Batteries mainly contain heavy metals such as cadmium, in addition to trace amounts of mercury, which is a toxic substance. There are reports that batteries contain mercury, cadmium, lead, arsenic, etc., which is inaccurate.

Waste batteries are used and discarded batteries. The environmental impact of waste batteries and how they are disposed of are still controversial. Many people believe that waste batteries are seriously harmful to the environment and should be concentrated.

However, officials from China's State Environmental Protection Administration (SEPA) believe that previous reports about the harm to the environment caused by waste batteries lack scientific basis. And China has not reacted much to the ** of waste batteries.

A battery is a device that converts chemical energy into electrical energy in a cup, tank, or other container or composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It has a positive electrode and a negative electrode. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy.

Such as solar cells.

There are roughly three ways to dispose of waste batteries in the world: solidification and deep burial, storage in waste mines, and utilization.

1. Solidify and bury deep and store in abandoned mines.

For example, a factory in France extracts nickel and cadmium from it, which is then used to make steel, and cadmium is reused to produce batteries. The rest of the waste batteries are generally sent to specialized toxic and hazardous landfills, but this is not only too expensive but also wasteful, because there are still many useful substances that can be used as raw materials.

2 **Utilization.

1) Heat treatment (2) "Wet treatment" (3) Vacuum heat treatment method.

Waste batteries contain a large amount of heavy metals and electrolyte solutions such as waste acid and waste alkali. If discarded at will, rotten batteries can destroy our water sources and erode the crops and land we depend on, and our living environment is under great threat.

According to the data, a No. 1 battery rots in the ground, which can permanently lose the use value of square meters of soil; One coin cell battery can make 600 tons of water undrinkable, which is equivalent to the amount of water a person drinks in a lifetime. Batteries contain three of the five substances that pose the greatest threat to the natural environment: mercury, lead, and cadmium.

If waste batteries are mixed with domestic garbage and landfilled, the leached mercury and heavy metal substances will penetrate the soil, pollute the groundwater, and then enter the fish and crops, destroying the living environment of human beings and indirectly threatening human health.

Waste batteries contain toxic substances such as mercury, cadmium, lead, zinc and other heavy metals. Mercury poisoning in humans can damage the central nervous system, with a mortality rate of up to 40%; The main hazard of cadmium is nephrotoxicity, which is a carcinogen; Consumption of foods containing lead affects enzymes and normal heme synthesis, affecting the nervous system.

Within one month of landfill treatment, 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 body, causing pollution to the environment.

According to environmental experts, if.

6 tonnes of household waste mixed with a mercury-containing battery, and when the waste is landfilled, the concentration of mercury in the soil will exceed the safety standard; If waste batteries are mixed with domestic garbage and enter the incineration plant, the mercury, cadmium and other metals in them will be gasified and discharged into the atmosphere at high temperatures, polluting the atmospheric environment and affecting human health.

Batteries are very polluting to the environment, and one battery can pollute dozens of cubic meters of water. Some even say that waste batteries can cause hazards such as Minamata disease in Japan when disposed of with household waste, and a No. 5 waste battery can make one square meter of land wasted.

Batteries mainly contain iron, zinc, manganese, etc., in addition to trace amounts of mercury, which is toxic.

1973 If the waste battery is burned, some heavy metals are volatile at high temperatures, and some of them become bottom ash after incineration, and some of them are volatilized by heat gasification and carried away by flue gas, and condense into uniform small particles after cold air, mercury, cadmium and lead are easier to be enriched in fly ash. The hazards of used batteries. One button battery can pollute 600,000 liters of water, which is equivalent to a person's lifetime water intake.

A battery rotting in the ground can make a square meter of land lose its use value, so the section of waste batteries is said to be a "pollution bomb". The ordinary dry batteries used in daily life mainly include acidic manganese batteries and alkaline manganese batteries, which contain mercury, manganese, cadmium, lead, zinc and other metal substances. After the used battery is abandoned, the shell of the battery will slowly decay, and the heavy metal substances in it will gradually sink into the water and soil, causing pollution.

The biggest feature of heavy metal pollution is that it cannot be degraded in nature, and the pollution can only be eliminated through purification. The hazards of used batteries are mainly focused on the small amount of heavy metals contained in them.

The environmental pollution in the lithium battery is CO, the lithium cobalt oxide that should be used for the positive electrode, and the cobalt in the periodic table is 27 in front of the iron and nickel, as a transition metal, the impact on the environment is there, but not large.

In addition, there is the electrolyte used in lithium batteries, which is organic and has some impact on the environment. In general, lithium batteries have little impact on the environment.

In order to improve safety and voltage, scientists have invented materials such as graphite and lithium cobalt oxide to store lithium atoms. The molecular structure of these materials forms tiny storage lattices at the nanoscale that can be used to store lithium atoms. In this way, even if the battery shell is ruptured and oxygen enters, the oxygen molecules will be too large to enter these small storage compartments, so that the lithium atoms will not come into contact with oxygen and be avoided**.

A battery thrown on the ground can make 1. The ground within is forever unusable.

One square meter of land is the amount of water a person uses in their lifetime.

Battery No. 5 caused the loss of 1 square meter of soil;

One button battery can pollute 600,000 liters of water, which is equivalent to the amount of water a person drinks in a lifetime.

Cause great harm!
