What are the symptoms of battery poisoning

Some babies like to taste everything. Sometimes they are very interested in batteries and bite them with their mouths. Parents must stop this in time because batteries contain mercury, which is harmful to health and will cause unhealthy growth and development. In order to avoid mercury damage, we must pay attention to the various symptoms of children. So, what are the symptoms of poisoning?

1. Mercury Hazards

Mercury has a low volatilization temperature and is a highly toxic heavy metal. The soil in many places also contains trace amounts of mercury. During the mining, refining and processing of mercury-containing products, if the sealing measures are not complete, the mercury (vapor) released into the air will have a great impact on the health of operators.

If mercury from waste batteries leaks into human brain cells, the human nervous system will be severely damaged. Cadmium can damage the liver and kidneys, and in severe cases, cause bone deformation.

Although batteries contain mercury, the amount is very small because it is an additive. Even for high-mercury batteries, the mercury content is generally less than one thousandth of the battery weight. The amount of mercury used by China's battery industry throughout the year is roughly equivalent to the amount of mercury in the annual wastewater discharged by a company that produces mercury-based polyvinyl chloride, mercury-based gold refining, or high-mercury lead and zinc mining. Since the battery consumption area is large, the impact of mercury-containing waste batteries entering the domestic waste treatment system on the environment is much smaller than the impact caused by the discharge of mercury-containing wastewater by the aforementioned chemical company. Moreover, the battery uses stainless steel or carbon steel as the outer casing, which effectively prevents the leakage of mercury. Therefore, the harm caused by discarded used batteries in domestic waste is minimal, and it is objectively impossible to cause harm such as Minamata disease. Japan's Minamata disease was caused by chemical companies discharging large amounts of mercury-containing wastewater into a river over decades, leading to the gradual accumulation of mercury in the downstream water system.

2. Acid and heavy metal lead

Some waste batteries also contain acid and heavy metal lead, which, if leaked into the natural world, can cause soil and water pollution and ultimately cause harm to humans.
