What are the hazards of discarded batteries? What are the dangers to people?

Hazards of waste batteries: Mercury in batteries discarded in nature will slowly spill out of batteries, enter the soil or water source, and then enter the human body through crops, damaging human kidneys. Under the action of microorganisms, inorganic mercury can be converted into methylmercury, which gathers in the body of fish, and after people eat this fish, methylmercury will enter human brain cells, causing serious damage to the human nervous system, and the serious ones will go crazy and die.

The famous Japanese Minamata disease is caused by methylmercury. Cadmium exudates and pollutes land and water, and eventually enters the human body to damage the liver and kidneys, and can also cause bone weakness, and in severe cases, bone deformation. The leakage of acid and heavy metal lead contained in automobile waste batteries into nature can cause soil and water pollution, and ultimately cause harm to people.

**Waste batteries: The popularity and variety of household appliances have led to a dramatic increase in the use of batteries. Waste batteries are mixed in garbage, which not only pollutes the environment, but is also a waste.

The annual consumption of batteries in the country is 3 billion, and 740 tons of copper, 10,000 tons of zinc and 10,000 tons of manganese powder are lost due to the lack of **. We should separate the used batteries from other garbage and send them to **. Many countries attach great importance to the use of used batteries.

Many stores in Germany require customers to return the used batteries to the store when they buy them; Japan's proprietary sorting bins collect different waste batteries.

Disposal methods of household waste.

At present, there are four main ways to dispose of municipal waste in the world: sorting, landfilling, composting and incineration.

1 Landfill. Landfill disposal takes up a lot of land. At the same time, the harmful components in garbage will also cause serious pollution to the atmosphere, soil and water sources, which not only damages the ecological environment, but also seriously endangers human health.

2 Compost. Composting treatment should sort and classify garbage, requiring a high organic content of garbage. Moreover, the composting process cannot be reduced, and it still needs to occupy a lot of land.

3 Incineration. The essence of incineration is to oxidize organic waste into inert gaseous substances and inorganic non-combustibles under the conditions of high temperature and sufficient oxygen supply to form stable solid residues. First, the waste is burned in an incinerator to release heat energy, and then the waste heat** can be used to generate heat or electricity.

After the flue gas is purified, it is discharged, and a small amount of residual residue is discharged, landfilled or used for other purposes. Its advantages are rapid volume reduction and complete high temperature harmlessness, small footprint, low impact on the surrounding environment, and thermal energy**. Therefore, incineration of MSW is an effective treatment method for harmlessness, reduction and recycling.

With the continuous enhancement of people's environmental awareness and the improvement of comprehensive utilization technologies such as thermal energy, the proportion of domestic waste treatment using incineration technology in various countries around the world is increasing year by year.

It is mainly a heavy metal hazard, especially the batteries of small factories.

It is very harmful to the soil.

If the waste battery is not properly disposed of, it will bring certain harm to human beings and the environment, mainly including the following aspects:

1.Heavy metal pollution: Waste and old batteries contain a large amount of heavy metals, such as lead, cadmium, mercury, etc., which may leach into the soil, water and air, causing pollution to the environment and irreversible effects on the ecosystem.

If people come into contact with these contaminated soil or water sources, there can be a risk to health.

2.**Or leakage: The electrolyte of the orange macro in the used battery is a strong acid or strong base, which may cause burns or damage to the body of the person if not properly disposed of.

In addition, if the battery is discarded in a high-temperature or high-pressure environment, it can also cause the battery** or leakage, further exacerbating the danger to personnel.

3.Energy waste: There is still a certain amount of energy storage in waste batteries, and if it is not utilized, a lot of resources and energy will be wasted.

Therefore, improper disposal of used batteries may bring significant harm to humans and the environment. In order to avoid these hazards, we should actively promote the concept of battery utilization, ensure that waste batteries are properly disposed of, and take necessary safety measures and scientific management methods, so as to minimize the danger.

1. The ordinary dry batteries we use daily contain mercury, manganese, cadmium, lead, zinc, nickel and other metal substances. After the waste battery is abandoned, the shell of the battery will slowly corrode, and the heavy metal substances in it will gradually seep into the water and soil, causing pollution.

2. If a person eats the crops produced on the polluted land or drinks the polluted water, these toxic heavy metals will enter the human body and slowly deposit them, causing a great threat to human health.

The battery contains heavy metals such as mercury, cadmium, lead, etc., and after the waste battery is abandoned, the shell of the battery will slowly corrode, and the heavy metal substances contained in it will gradually seep into the water body and soil, causing pollution. If a person eats crops produced on polluted land or drinks polluted water, these toxic heavy metals will enter the human body and slowly deposit, which will pose a great threat to human health. Scientific studies have shown that an ordinary battery can pollute 600,000 liters of water after being thrown into nature, which is equivalent to the water consumption of a person's lifetime, and China consumes about 7 billion such batteries every year.

In order to avoid the harm caused by the key pins caused by waste batteries, there are roughly three types of waste battery treatment formulas in the world: solidification and deep burial, storage in waste mines, and utilization.

The harm of waste batteries to people is mainly manifested in the following aspects:

1.Heavy metal poisoning: Waste batteries contain a large amount of heavy metals, such as lead, cadmium, mercury, etc., which may cause poisoning if they enter the human body.

Heavy metal poisoning can seriously affect the health of human organs, leading to symptoms such as anemia, kidney damage, and neurological diseases.

2.Chemical burns: The electrolyte of a used battery is a strong acid or alkali that can cause burn damage to the human body if not handled properly.

After coming into contact with used batteries, there will be burns, redness, swelling, heat pain and other symptoms on the hands or **, and in severe cases, it may even lead to tissue necrosis.

3.Batteries**: Used batteries that are subjected to high temperatures or other external forces may trigger batteries**, producing sparks and violent chemical reactions. This poses a serious danger to the surrounding environment and the human body.

Therefore, in order to avoid the potential harm caused by waste batteries, we should properly dispose of waste batteries, and take necessary safety measures and protective measures during the treatment process, such as wearing gloves, masks and other protective equipment, and choose the appropriate treatment method to properly carry out the waste batteries and dispose of them. At the same time, we should also actively promote environmental awareness, improve people's attention to waste batteries, and form a good atmosphere for the whole society to pay attention to and manage waste batteries.

If batteries are discarded in the soil, heavy metals such as lead, mercury, and cadmium can contaminate the soil, and rotten batteries can also contaminate nearby water sources. Severe heavy metal poisoning can occur if people eat food grown on contaminated soil or drink contaminated water. A rotten No. 1 battery, the heavy metals in which can make a square meter of soil incapable of planting, a rotten button battery can pollute 600,000 liters of water.
