How does battery mercury enter the human body, and is there mercury in the battery?

Mercury discarded in natural batteries can slowly spill out of batteries, enter soil or water sources, 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 battery pollution and its treatment have become one of the most concerned environmental protection focuses in the society.

The relevant person of the Science and Technology Standards Department of the State Environmental Protection Administration believes that with the continuous expansion of the types, production and use of batteries in China, the number and types of waste batteries are also increasing. 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. It is understood that the waste batteries that are harmful to human health and the ecological environment and are included in the hazardous waste control list mainly include:

mercury-containing batteries, mainly mercury oxide batteries; lead-acid batteries; Cadmium-containing batteries, mainly nickel-cadmium batteries.

Mercury can volatilize, enter the air, and breathe into the body.

Batteries contain mercury.

Introduction: For a long time, in the dry batteries produced in China, a toxic substance——— mercury or mercury compounds should be added as corrosion inhibitors to improve the storage life of the battery and prevent battery leakage. The mercury content of alkaline dry batteries in China is 1 5, and the mercury content of neutral dry batteries is up to dozens of tons every year in the country.

Mercury is what we commonly call "mercury". Among more than 80 kinds of metal elements, only mercury is liquid at room temperature, which is a silvery-white liquid metal that flows easily, hence the name "mercury". Both mercury and mercury compounds are toxic, and scientists have found that mercury has significant neurotoxicity, in addition to adverse effects on the endocrine system, immune system, etc.

Minamata disease, a public pollution disease that shocked the world in the 50s of the 20th century——— was caused by mercury pollution.

Yes, Japan and South Korea need to add mercury to produce batteries, and then export to the European Union and the United States, the United States is the number one consumer of dry batteries, only to contain a small amount of mercury, second only to the United States of Europe, batteries contain a lot of mercury, so waste dry batteries need to **.
