Accumulation of Pb, Fe, Mn, Cu and Zn in plants and choice of hyperaccumulator plant in the industrial town of Vian, Iran

Abstract

Various industrial activities contribute heavy metals to the soil environment directly or indirectly through the release of solid wastes, waste gases, and wastewater. Phytoremediation can be potentially used to remedy metal-contaminated sites. A major step towards the development of phytoremediation of heavy metal-impacted soils is the discovery of the heavy metal hyperaccumulation in plants. This study evaluated the potential of 7 species growing on a contaminated site in an industrial area. Several established criteria to define a hyperaccumulator plant were applied. The case study was represented by an industrial town in the Hamedan province in the central-western part of Iran. This study showed that most of the sampled species were able to grow in heavily metal-contaminated soils and were also able to accumulate extraordinarily high concentrations of some metals such as Pb, Fe, Mn, Cu and Zn. Based on the obtained results and using the most common criteria, Camphorosma monospeliacum for Pb and Fe, and Salsola soda and Circium arvense for Pb can be classified as hyperaccumulators and, therefore, they have suitable potential for the phytoremediation of contaminated soils

PHYTOREMEDIATION OF HEAVY METALS CONTAMINATED SOIL USING Brassica juncea (L.) IN BANY EL- HARETH, SANA'A- YEMEN

“…Availability of organic compounds and mineral elements in contaminated soil with waste water enhancement growth and activity of Brassica juncea plant for remove Pb from contaminated soil. These results are in agreement with the results obtained by Lorestani et al, (2011).…”

“…In fact Brassica juncea plant is able to accumulate unusually high concentrations of Zn in their aboveground parts. This result is similar with result obtained by Lorestani et al,(2011) Heavy metals are bound to soil components in varying degrees, depending on soil conditions such as pH, clay content, organic matter, redox potential. Plant available metals include species that are readily soluble or exchangeable, while metals that are more strongly adsorbed/bound to organic matter or co-precipitated with oxides are generally not available for plant uptake.…”

“…Trace element contamination of soil due to natural or anthropogenic activity (mainly urbanization and industry) threatens ecosystems, surface, and ground waters, food safety, and human health, as well as decrease the plant yield [1]. Elements can be divided into:…”

The Removal Efficacy of Heavy Metals and Total Petroleum Hydrocarbons from Contaminated Soils by Integrated Bio-phytoremediation

“…For decreasing pollutants as well as responsive to maintaining the soil environment, integrated remediation such as phytoremediation, was regardes as an better technology to remove heavy metal by phytoextraction from plants like Poplar (Populus bonatii Levl.) and Sun Hemp (Crotalaria juncea L.) (Etim, 2012;Lorestani, 2011;Pulford and Watson, 2003;Baker et al, 2000;Raskin and Ensley, 2000;Carman et al, 1998;Critcchley, 1998;Watanabe, 1997;Cunningham and Ow, 1996). In the literatures, green remediation technology shows having an ability to remove pollutants that the related exercise on-site field to remove TPH and heavy metal was absent in Tai-wan.…”
