The role of plants in refinement of heavy metals in soil
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 23
Abstract
Due to the increasing industrial activity in recent years and the subsequent entry of inorganic and organic contaminants in soil, including the problems that threaten human health. Phytoremediation is used by Green Plant Engineering including herbaceous and woody species for removal of pollutants from water and soil or mitigation of environmental pollutants such as heavy metals, trace elements, organic compounds and radioactive material. The main pollutants are inorganic compounds, heavy metals and soil microorganisms are able to degrade organic contaminants, but the microbial decomposition of organic or metal to metal there are changes to this part of the plant is today. The main pollutants inorganic compounds, are heavy metals and soil micro organisms are able to degrade organic contaminants, But for microbial decomposition metals, there needs to be organic or metallic changes in their, that today is the use of plants for this section. In addition, the soil base of terrestrial creatures, especially human societies, is a unique environment for life, especially the life of plants. Unlike air and water pollution, soil contamination is not easily measurable in terms of chemical composition and not defines a soil free from pollution. So we have to study potential soil contamination issues in the context of anticipated risks and damage the functioning of soil. With the development of projects and soils contaminated by heavy metals, soil structure for plant growth and development is poisonous and dangerous, and also destroys soil biodiversity, it is necessary to resolve these problems by using purified plant.
