1. Types of batteries: Batteries mainly include disposable batteries, secondary batteries and car batteries. Disposable batteries include button batteries, ordinary zinc-manganese dry batteries and alkaline batteries, and disposable batteries contain mercury. Secondary batteries mainly refer to rechargeable batteries, which contain heavy metal cadmium. Automobile waste batteries contain acid and heavy metal lead.

2. The hazards of waste batteries: mercury discarded in natural batteries will slowly overflow from the battery, enter the soil or water source, and then enter the human body through crops, damaging the kidneys. Under the action of microorganisms, inorganic mercury can be converted into methylmercury, which gathers in the body of fish. After people eat this fish, methylmercury will enter human brain cells, causing serious damage to the human nervous system. Will go crazy to death. The famous Japanese Minamata disease is caused by methylmercury. Cadmium exudates and pollutes the land and water, and eventually enters the human body to cause damage to the liver and kidneys. It can also cause bone weakness and severe bone deformation. Automobile waste batteries containing acid and heavy metal lead leakage to nature can cause soil and water pollution, and ultimately cause harm to people.

Recycling waste batteries: The popularity of household appliances and the increase in types have led to a sharp increase in battery usage. Waste batteries mixed in the garbage, not only pollute the environment, but also a waste. The annual consumption of batteries in the country is 3 billion, and 740 tons of copper, 16000 tons of zinc and 97000 tons of manganese powder are lost due to no recovery. We should separate used batteries from other garbage and collect them for recycling. Many countries attach great importance to the recycling of waste batteries. Many stores in Germany require customers to return used batteries to the store when buying batteries. Japan's proprietary sorting box collects different waste batteries.

4. Knowledge Card: Do you know "pain disease"? Both "pain disease" and "Minamata disease" are industrial pollution diseases that occur in Japan. This is due to the fact that industrial wastewater containing cadmium or mercury contaminates the soil and water sources and enters the human food chain. "Minamata disease" is mercury poisoning, patients due to the accumulation of large amounts of methylmercury in the body and the occurrence of brain central nerve and peripheral nerve damage, mild hand and foot paralysis, severe death. "Pain disease" is cadmium poisoning, patients with hand and foot pain, all over the body are prone to fracture. People who have this disease are always shouting, "It hurts! It hurts!", Until death, so called "pain disease". Since ordinary dry batteries contain these two toxic elements, the battery is always lurking in pollution from production to waste. Battery recycling is imperative!

I deeply understand the harm of used batteries, but how many people can actually participate in the work of recycling used batteries? I will gather up the used batteries and throw them in when I see the recycled boxes. When I was in college, there was a waste battery recycling box under each dormitory building, but after graduation, I found that this recycling box did not know where it went. There are no such devices near the home.

Can you tell me where I can recycle used batteries? Together to actively participate in environmental protection, together with the implementation of waste battery recycling work!
