How harmful is it to work in a battery factory?

Based on an analysis of your primary complaint, you have been informed that most batteries contain mercury and when they are discarded on the earth's surface, the multiple layers of metal oxidize and rust. Mercury will slowly leak out of the battery, enter the soil or seep into groundwater, and then enter the human body through crops or drinking water, and damage the human kidneys. Here, mercury can also be converted into inorganic mercury, which is converted into methylmercury by microorganisms and accumulates in the fish. After eating this fish, methylmercury can cause damage to human brain cells.

The main harm of waste batteries is that they contain heavy metals, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various pathways and are difficult to eliminate after long-term accumulation, damaging the nervous system, hematopoietic function, and bones, and may even cause cancer. Lead: nervous system (neurasthenia, numbness of hands and feet), digestive system (indigestion, abdominal cramps), blood poisoning and other diseases. Mercury: Altered mental state is a major symptom of mercury poisoning. Rapid pulse, muscle tremors, oral and digestive system lesions. Cadmium and manganese: mainly harm the nervous system. The components of these batteries are sealed inside the battery shell during use and will not affect the environment. However, after long-term mechanical wear and corrosion, the heavy metals and acids and alkalis inside will leak out and enter the soil or water sources, and then enter the human food chain through various channels.

What diseases will occur once the human body absorbs these heavy metals? According to relevant experts, mercury is a highly toxic heavy metal that is extremely destructive to the human central nervous system. The Minamata disease that shocked China and the world in Japan in the 1950s was caused by mercury pollution. The mercury content of mercury-containing alkaline dry batteries produced in my country is currently 1%-5%, and the mercury content of neutral dry batteries is 0.025%. The mercury consumed in battery production in my country reaches dozens of tons each year. Cadmium can easily cause chronic poisoning in the human body. The main symptoms are emphysema, osteomalacia, anemia, and it may cause paralysis. Lead is the most difficult to excrete after entering the human body, and it interferes with kidney and reproductive functions.

Since battery pollution has the characteristics of long cycle and high concealment, its potential harm is quite serious, and improper handling will cause secondary pollution. According to Dr. Yang Yifu, some farmers in a coastal province of my country improperly handled the recycling of lead from lead-acid batteries and dumped the waste liquid containing lead and sulfuric acid, which not only caused lead poisoning but also prevented the growth of local crops.
