Heavy metals have been spreading into the atmosphere and soil through human activities and natural means since ancient times. Earthquakes, volcanic eruptions, floods, etc. Heavy metals entering surface and subsurface waters for various reasons spread throughout the ecosystem. But natural spread also has its limits. Water and air pollutants from industrial activities are more likely to be chemically released into the environment. Industrialization has led to heavy metal pollution, which has increased over time. We are exposed to more than 35 metals in our external environment, 23 of which are heavy metals. The definition of heavy metal is used for metals with a density above 5 g/cm³. Lead (Pb), cadmium (Cd), chromium (Cr), iron (Fe), cobalt (Co), copper (Cu), nickel (Ni), mercury (Hg) and zinc (Zn) are frequently encountered. Heavy metals are released into the atmosphere from a variety of sources and through various process steps. Heavy metals entering the atmosphere from various sources can affect the ecological balance by mixing with the soil, surface waters, and even groundwater through dry and wet accumulation.
