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, a Novel Method for Removal of Heavy Metals from Environment: Biochemical and Molecular Mechanisms
Abstract: Heavy metals are constantly released into the environment as a result of human, agricultural and industrial activities. Thus, there is an urgent need to develop a low-cost, effective, and sustainable method for their detoxification. Phytoremediation is the use of plants to remediate metal contaminated sites. Sesbania plants are being grown in the presence of different concentrations o...
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...
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 کاملAbility of some crops for phytoremediation of nickel and zinc heavy metals from contaminated soils
The present study was aimed at comparing the ability of three crop plants for phytoremediation of zinc (Zn) and nickel (Zn) from soils. A factorial (3×2×3) experiment based on RCBD was used to compare the treatments, and was repeated three times. The first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (Zn) and nickel (Ni)) and the third factor ...
