Phytoremediation of heavy metals polluted environments
The rapid industrial development and agricultural growth and the indiscriminate production of pollutants have faced problems for human societies and the environment. Accumulation and pollution of heavy metals in the environment are the main important problems that as a result of human activities through extraction from ore and processing for various applications has led to the release of these ...
متن کاملPhytoremediation of soils polluted by heavy metals using Vetiver grass and Tall Fescue
Phytoremediation is a biological method to improve soils contaminated with heavy metals. The objective of the present research was to study the capability of Vetiver grass and Tall Fescue in refining and reducing pollution of Cd, Cu and Zn from contaminated soils. The research was implemented in greenhouse during two separate tests (Vetiver grass and Tall Fescue) in a completely randomized desi...
متن کاملPhytoremediation of soil metals.
The phytoremediation of metal-contaminated soils offers a low-cost method for soil remediation and some extracted metals may be recycled for value. Both the phytoextraction of metals and the phytovolatilization of Se or Hg by plants offer great promise for commercial development. Natural metal hyperaccumulator phenotype is much more important than high-yield ability when using plants to remove ...
متن کاملPhytoremediation of heavy metals by Trifolium alexandrinum
The release and persistence of toxic heavy metals into the natural environment is a serious concern especially in urban areas. The problem of heavy metal pollution is gaining momentum from year to year as more and more amounts of heavy metals are extracted from their ores and released into the environmental segments (water, air and soil) during processing or afterwards. Heavy metals are essenti...
متن کاملPhytoremediation of Heavy Metals- A Review
An excess level of heavy metals are exposed into environment by industrial waste and fertilizers causes serious concern in nature as they are nonbiodegradable and accumulate at high levels. Heavy metals such as Pb, Zn, Cd, As etc. are one of the most toxic pollutants which show hazardous effects on all living livings. The prevailing purification technologies used for removal of contaminants fro...
