Phytoremediation is a potential cleanup technology for the removal of heavy metals from contaminated soils. Bidens maximowicziana is a new Pb hyperaccumulator, which not only has remarkable tolerance to Pb but also extraordinary accumulation capacity for Pb. The maximum Pb concentration was 1509.3 mg/kg in roots and 2164.7 mg/kg in overground tissues. The Pb distribution order in the B. maximow...

Phytoremediation use plants to remove pollutants from the environment and render them harmless. It is an economically feasible and sustainable ways regarding to the remediation of our environment without introducing any new contaminants. Considering the vast diversity of pollutants and the different kinds of environmental conditions are two most important aspects that plants used for the remedi...

Cumulative effect of urbanization, industrialization and population growth is increasing pressure on the limited natural resources. The change in living style has aggravated the problems. Among the diverse environmental problems, the discharge of heavy metals in environment through industrial, agricultural and domestic activities is of great concern. Removal of heavy metal from environment is a...

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 ...

Anthropogenic activities are resulting in an increase of the use and extraction of heavy metals. Heavy metals cannot be degraded and hence accumulate in the environment, having the potential to contaminate the food chain. This pollution threatens soil quality, plant survival and human health. The remediation of heavy metals deserves attention, but it is impaired by the cost of these processes. ...

Copper smelting and refinery factories are the final stages of a pyrometallurgical processing chain, and they cause many environmental challenges around the world. One of the most common environmental problems of these factories is toxic emissions. These toxic gases have harmful effects on the vegetation, animal species, soils, and water resources around the factories. Phytoremediation can play...

Air pollution has been becoming a necessary evil with rapid industrialization and urbanization around the world, after it results in kinds of human health problems, such as ophthalmic, respiratory and cardiovascular diseases (Brunekreef & Holgate, 2002; Giles et al., 2011; Gudmundsson, 2011; Jamrozik & Musk, 2011; Miller et al., 2007; Nandasena, 2010). The direst threat posted by air pollution ...

Lemna spp. of the family Lemnaceae have been widely studied for their potential application in phytoremediation. A few Lemna species are already being adopted to enhance natural attenuation for both organic and inorganic pollution in polishing ponds of wastewater treatment facilities, and constructed wetland designed for decontamination of metal pollution. In view of this growing interest, we r...

Phytoremediation is an emerging technology that employs the use of higher plants for the cleanup of contaminated environments. Fundamental and applied research have unequivocally demonstrated that selected plant species possess the genetic potential to remove, degrade, metabolize, or immobilize a wide range of contaminants. Despite this tremendous potential, phytoremediation is yet to become a ...

The increasing popularity of urban agriculture as a method of localizing food systems has created a mounting need to address soil pollution in urban farms. Lead is an especially pervasive pollutant in urban soils with a number of detrimental health effects. Phytoremediation, the use of plants to extract or degrade pollutants, has shown promise for cleaning up leadcontaminated soils, yet its pot...
