Identification of the Hyper Accumulator Plants in Copper and Iron Mine in Iran

Abstract

The aim of present study was to identify accumulator plants that are effective for phytoremediation. We chose a mine of Iron and Copper named Hame Kasi that located western north of Hamedan city as a polluted area. In this region concentration of heavy metals is several times more than non-polluted area. Seventeen plant species and 6 soil samples were collected from this region for determination of heavy metals content. Atomic Absorption Spectrophotometer (AAS) was used for analysis of heavy metals in soil and plant samples, then tested plant species were grouped on the basis of their accumulation capability of heavy metals. The results of this research showed that there are some hyper accumulator plants in this area that can concentrate heavy metals in their different parts thus they can be used for remediation of polluted area.

Effect of the Heavy Metals on the Developmental Stages of Ovule and Seed Proteins in Chenopodium botrys L. (Chenopodiaceae)

“…As shown in Table 1, the amounts of Fe, Mn, Zn, and Cu were, respectively, 17, 12, 12.5, and 11.2 times higher than those in the nonpolluted soils [11]. C. botrys L. was collected from January to June in 2007.…”

Uptake of Heavy Metals from Urban Wastewater Contaminated Soils by Using Selected Crop Species of Mysuru City, India

“…Heavy metals in soil and plant samples, tested plant species were grouped on the basis of their accumulation capability of heavy metals. The results of this research showed that there are some hyper accumulator plants in this area that can concentrate heavy metals in their different parts thus they can be used for remediation of polluted area (Behrouz E. Malayeri, 2008).Treatment methods were developed to reduce the hazardous elements in wastewater before its use on agricultural fields. However, in many developing countries wastewater is still used without any treatment as treatment facilities are not available, people are not aware of the health and environmental hazards and the WHO guidelines are not feasible.…”

Selenium Phytoremediation by Giant Reed

“…It is documented that, heavy metals cause oxidative stress (Mudipalli 2008 ) by formation of free radicals. Furthermore, they can replace essential metals in pigments or enzymes disrupting their function (Malayeri et al 2008 ). Regarding their toxicities, the most problematic heavy metals are As, Cd, Cr, Cu, Hg, Pb, Se, Sn, and Zn (Ghosh 2010 ).…”
