The hazards of waste batteries mainly focus on the small amounts of heavy metals contained in them, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various pathways and accumulate for a long time, causing damage to the nervous system, hematopoietic function, and bones, and even leading to cancer.

1. Mercury hazards

Mercury has a low volatilization temperature and is a highly toxic heavy metal. In many places, soil also contains trace amounts of mercury. During the process of mercury mining, extraction, and processing of mercury containing products, if the sealing measures are not complete enough, the mercury (vapor) released into the air has a significant impact on the health of operators.

After mercury overflows from waste batteries, if it enters human brain cells, the human nervous system will be severely damaged. Cadmium can damage the liver and kidneys, and in severe cases, cause bone deformities.

Although mercury is present in batteries, its content is very low as it is an additive. Even for high mercury batteries, the mercury content is generally within one thousandth of the battery weight. The annual mercury consumption in China's battery industry is roughly equivalent to the mercury content in the wastewater discharged by a mercury based polyvinyl chloride, mercury based gold refining, or high mercury lead-zinc mining enterprise. Due to the large consumption area of batteries, the impact of mercury containing waste batteries entering the household waste treatment system on the environment is much smaller than the impact caused by the discharge of mercury containing wastewater from a chemical enterprise mentioned above. Moreover, the batteries use stainless steel or carbon steel as the outer sheath, effectively preventing mercury leakage. Therefore, the scattered disposal of waste batteries in household waste poses minimal harm and objectively cannot cause harm such as Minamata disease. Minamata disease in Japan is caused by chemical companies discharging large amounts of mercury containing wastewater into a river for decades, leading to the gradual accumulation of mercury in downstream water systems.

2. Acid and heavy metal lead

Some waste batteries also contain acid and heavy metal lead, which can cause soil and water pollution if leaked into nature, ultimately posing a hazard to humans.

Waste batteries should not be discarded casually. They should be properly disposed of. If you want to know how to dispose of waste batteries in daily life, please go to the Baibai Safety Net. More knowledge about toxic substances can be found on the Baibai Safety Net.

1. Harm to human health. Waste batteries contain a large amount of heavy metals such as mercury, cadmium, manganese, and lead. When waste batteries are exposed to sunlight and rain, the surface layer will rust, and the components will penetrate into the soil and groundwater. Once people consume crops produced on contaminated land or drink contaminated water, these toxic heavy metals will enter their bodies and slowly deposit, posing a great threat to human health.

2. Environmental hazards. A No.1 battery that rots in the soil can cause one square meter of land to lose its use value. A button battery can pollute 600000 liters of water, equivalent to the amount of water a person drinks in their lifetime. According to statistics, the amount of mercury entering the natural environment each year due to waste batteries in Beijing alone reaches 29 tons.

A battery refers to a part of the space in a cup, tank, or other container or composite container that contains an electrolyte solution and metal electrodes to generate electric current, and is a device that can convert chemical energy into electrical energy.

There are positive and negative poles. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Like solar cells.

The harm of waste batteries: When the chemical substances inside the battery react completely, the battery can no longer provide power and becomes a waste battery. Usually, people throw it away and buy a new one. Most people would say that this is quite normal. But they didn't expect that even with their every move, they were destroying their homeland - Earth. Perhaps someone may ask, 'What's so amazing about this small thing for Earth! What kind of destruction is there?' Batteries may not seem as destructive, but we can't look at everything on the surface. Waste batteries contain a large amount of heavy metals such as mercury, cadmium, manganese, and lead. When waste batteries are exposed to sunlight and rain, the surface layer will rust, and the components will penetrate into the soil and groundwater. Once people consume crops produced on contaminated land or drink contaminated water, these toxic heavy metals will enter their bodies and slowly deposit, posing a great threat to human health! According to measurements, one No. 1 battery can cause one square meter of land to lose its use value if it rots in the soil; A button battery can pollute 600000 liters of water, equivalent to the amount of water a person drinks in their lifetime. Approximately 5 billion people around the world lose one battery per person per month, resulting in a cumulative total of 60 billion batteries per year. The destructive power on the Earth is enormous, and the consequences of its harm to human health are even more unimaginable. According to statistics, the amount of mercury entering the natural environment due to waste batteries in Beijing alone reaches 29.6 tons per year, which is a headache. So waste batteries cannot be discarded at will. Countries attach great importance to the recycling of waste batteries. In addition, various zinc manganese sub batteries produced in developed countries are now mercury free batteries. Moreover, developed countries do not allow the import of mercury containing batteries. Therefore, China's mercury containing batteries cannot enter developed regions in Europe and America. After being discarded into nature, a button battery can pollute 600000 liters of water, which is equivalent to a person's lifetime water consumption. And China consumes 7 billion of these batteries every year... Batteries contain mercury, which is a liquid metal. Specific gravity 13.6, melting point -39.3 ℃, boiling point 357 ℃. Mercury can evaporate at room temperature, and its vapor is colorless, odorless, and seven times heavier than air. Mercury and its compounds are highly toxic, especially the organic compounds of mercury are even more toxic. Fish living in water with a mercury content of 0.01-0.02 milligrams per liter will be poisoned; If a person consumes 0.1 grams of mercury, they will be poisoned to death.

There is also cadmium in the battery: cadmium is a highly toxic heavy metal, and most of its compounds are also toxic substances. The shocking "pain pain" in Japan is caused by cadmium pollution

Waste batteries are a major killer that endangers our living environment! A small button battery can pollute 600 cubic meters of water, equivalent to a person's lifetime of drinking water; A No.1 battery that rots in the ground can cause one square meter of land to lose its use value and cause permanent pollution.

Among the substances that pose the greatest threat to the natural environment, batteries contain various substances such as mercury, lead, cadmium, etc. Mercury has strong toxicity and great destructive power on the central nervous system of the human body. The Minamata disease that shocked both China and foreign countries in the 1950s occurred in Japan due to mercury pollution; Lead can cause neurological disorders, nephritis, etc; Cadmium is highly prone to chronic poisoning in the human body, with the main symptoms being emphysema, osteomalacia, anemia, and the possibility of paralysis; Lead is the most difficult to excrete after entering the human body, as it interferes with kidney and reproductive functions. If waste batteries are mixed into household waste and buried together, over time, the resulting heavy metals may contaminate groundwater and soil, and then enter fish and crops, damaging the human living environment and indirectly threatening human health.

The usage of batteries in our daily lives is rapidly increasing and has penetrated into every corner of our lives and work. China is a major producer and consumer of batteries, with an annual output of 14 billion units, accounting for one-third of the world's production. If there are about 360 million households in the country, and each household uses 10 pieces per year, the consumption is already 3.6 billion. If combined with group consumption, it would be no problem for billions of discarded batteries to emerge every year. If these batteries are not properly disposed of, they will directly or indirectly endanger people's health. The implementation and promotion of the activity of classifying and collecting waste batteries has been recognized by more and more people, and has received increasing attention, support, and participation.

Starting from myself, starting from every small thing around us, is our motto. Caring for the environment around us and participating in the classification and recycling of waste batteries is the responsibility and obligation of each and every one of us. Individual actions may seem insignificant, but by uniting the strength of each of us, we can support a civilization that coexists with nature and is sustainable

The hazards of waste batteries mainly focus on the small amounts of heavy metals contained in them, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various pathways and accumulate for a long time, causing damage to the nervous system, hematopoietic function, and bones, and even leading to cancer. Lead: neurological disorders (neurasthenia, numbness in hands and feet), digestive system disorders (indigestion, abdominal cramps), blood poisoning, and other diseases. Mercury: Changes in mental state are a major symptom of mercury poisoning. Pulse rate increases, muscle tremors, oral and digestive system disorders. If batteries are not properly disposed of after scrapping, mercury will slowly overflow into soil and water bodies, and enter the food chain through crops, posing a great threat to human health. One unit of electricity can make one square meter of land lose its agricultural value. After consuming water and food contaminated with mercury, people may experience mercury poisoning, which can range from mild symptoms such as shyness, loneliness, irritability, depression, and a metallic taste in the mouth, to severe symptoms such as tremors in the fingers, tongue, eyes, and head due to mercury toxicity. Cadmium and manganese: mainly harmful to the nervous system.

Here are several types of battery hazards:

Button batteries contain mercury. When they are discarded in nature and the outer metal rusts, mercury will slowly overflow from the battery, enter the soil or groundwater after rain, and then enter the human body through crops, damaging the internal organs. Under the action of microorganisms, inorganic mercury can be converted into methylmercury, which accumulates in the bodies of fish. After consuming this type of fish, methylmercury enters the brain cells of humans, causing serious damage to the nervous system, and in severe cases, it can lead to madness and death. Minamata disease in Japan is caused by methylmercury.

Rechargeable batteries generally contain harmful heavy metal cadmium, which seeps out of nature, pollutes land and water, and ultimately enters the human body. Cadmium can cause osteoporosis, bone deformation, bone pain, and serious consequences such as liver and kidney damage.

Ordinary dry batteries also contain mercury, lead, acid and alkali, which are harmful to the environment. Therefore, in developed countries, used batteries are classified as hazardous and toxic waste, and must be separately disposed of and recycled. They must not be casually discarded in nature. In Germany, used batteries can be delivered to every battery store, which is worth learning from.

According to relevant information, a single No.1 battery that rots in the ground can permanently render 1 square meter of soil unusable; A button battery can contaminate 600 tons of water, equivalent to a person's lifetime of drinking water. If waste batteries are mixed into household waste and buried together, or discarded casually, the leaked mercury and heavy metal substances will seep into the soil, pollute groundwater, and enter fish and crops, damaging the human living environment.

How harmful are waste batteries

Do you know how harmful waste batteries are? Have you checked? If I haven't checked, I'll tell you:

According to expert measurements, if a button battery is not properly treated. Throwing it into the river can pollute 600000 liters of water, equivalent to the amount of water a person drinks in their lifetime. A single No. 1 battery thrown into the soil can permanently render one square meter of land useless. If plants absorb harmful substances from the soil. Eating plants that have absorbed harmful substances can lead to diseases that directly harm human health, such as anemia.

If a No.1 battery has lost its function, it can be sent to the recycling department. This can reuse 60% of the electricity.

You see, the harm of waste batteries is so great. Starting from now on, from small things, let's take action together!
