Enhancing Phytoremediation Efficiency in Response to Environmetal Pollution Stress: In Plants and Environment
Environmental pollution, particularly contamination of soil and water resources, has been
accelerated as a result of global industrialization and so is considered as a major risk for
human communities throughout the world. Due to the adverse effects of organic and
inorganic pollutants on human health and environmental safety, it is necessary to be removed
in order to minimize the entry of these potentially toxics into the food chain. There are several
methods to remove the soil pollutants which are categorized into 3 main parts including
Comparison of natural humic substances and synthetic EDTA and NTA as washing agents of a heavy metal polluted soil
Ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic
acid (NTA), and other synthetic polycarboxylic acids have
been shown to possess substantial capacity as washing agents
of heavy metal–polluted soils, but they are environmentally
problematic. Th erefore, a sample of natural soluble humic
substances (HS) was tested as a possible substitute. Th e
effi ciency of HS to extract cadmium (Cd), copper (Cu), and
lead (Pb) from a strongly polluted calcareous urban soil was
compared with that of EDTA and NTA. Th e infl uence of
Evaluation of copper bioaccumulation and translocation in Jatropha curcas grown in a contaminated soil
Contamination of soils with copper (Cu) has become a serious problem in the environment.
Phytoremediation is an emerging green technology that uses green plants to remediate heavy
metal contaminated areas. This study was conducted to evaluate the potential of Jatropha
curcas for remediation of soils contaminated with Cu. Seedlings were planted in soils spiked
with Cu in amount of 0, 50, 100, 200, 300, and 400 mg kg–1 (Cu0, Cu50,Cu100,Cu200,Cu300,
and Cu400) for a period of five months. The maximum height and number of leaves were
