Heavy metals are a common compound in modern industry used for various purposes. The most common heavy metals are lead, cadmium, and mercury. These metals in the form of compounds are widely present around us — as parts of electric appliances in TV sets, computers, and daylight lamps containing mercury. Electric engineering appliances containing heavy metals, if thrown away with the domestic waste or simply abandoned, gradually degrade under the influence of weather or other conditions and thus get into the environment, where they are absorbed by the nature. And at last, heavy metals are absorbed by humans from the polluted water, food, plants, and animals. Special attention should be devoted to daylight bulbs, which contain highly volatile mercury — if the bulbs are damaged, the mercury gets into the air and from there in the lungs and blood of humans. Therefore these bulbs should be destroyed in a proper way, providing for collection and relevant processing of the mercury steam, which can be used in further production of new bulbs.
