In no case should you throw used batteries in the trash, it threatens people's health and the environment. Cities have special containers for collecting batteries, but many people continue to throw away batteries in non-designated places.

Why can't batteries be thrown away with household waste? A small battery contains various aggressive acids, mercury, and lead. When decomposed, it pollutes the soil, poisons water and air. It is called a time bomb.
A finger battery that is thrown into the trash pollutes almost 20 cubic meters of the earth with heavy metals. In one small battery, which ends up in a landfill, among tons of garbage, the amount of mercury exceeds all permissible standards.
If a battery has decomposed in the ground, vegetables grown on this soil cannot be eaten. This can lead to imperceptible gradual poisoning of the body.
