BIOLOGICAL REMEDY OF HEAVY METALS
Keywords:
heavy metals, biological treatment, bioremediation, biosorption, bioaccumulation, phytoremediation, ecology, environmental protectionAbstract
This article examines the harmful effects of heavy metals (lead, cadmium, mercury, nickel, chromium, etc.) on the environment and human health, as well as the potential of biological methods for their removal. Technologies such as bioremediation, biosorption, bioaccumulation, and phytoremediation are analyzed in terms of their effectiveness. Microorganisms (bacteria, fungi) and certain plant species are shown to possess the ability to absorb and neutralize heavy metal ions. Research indicates that biological methods are cost-effective, environmentally friendly, and provide long-term solutions. In conclusion, the wide application of biological technologies is emphasized as a necessary measure to reduce heavy metal pollution.
