In the present work, we aimed to focus on the identification and characterization of the heavy metal-tolerant plant species growing spontaneously at the tailings site of the Sarcheshmeh copper mine, south of Iran. Our aim was to find the plant species that were potentially useful for phytoextraction purposes. The concentrations of As, Cu, Mo, Ni, Zn, and Re were analyzed in soil as well as in t...
Phytoremediation is one of the best methods for cleaning heavy metal contaminated soils. In this method, tolerant plants with high absorption potential are used to clean up the pollutant. The purpose of this greenhouse study was to find the most suitable plants with the highest Zn translocation factor and shoot concentration. Soil samples were collected from zinc and lead Bama mine in Isfahan p...
the aim of present study was to investigate phytoremediation potential of puccinellia distans (jacq) parl using edta and dtpa and method of decreasing cd- chelating leacing risk. the soil samples spiked with cdcl2. the treatments comprised the following dosages 2.5dtpa, 5dtpa, 2.5edta, 5edta, 2.5edta+2.5dtpa, 2.5edta+5dtpa, 5edta+2.5dtpa, 5edta+5dtpa and control pots were not treated with edta ...
concern about arsenic pollution to soils and plants has been on an increase, throughout the world and an interaction of as with p due to the similarity in chemical characteristics has been also reported. in the present research, a factorial experiment was conducted as based upon a randomized complete block design of three replications including three levels of arsenic (0, 50 and 100 mg kg-1) fr...
rice (oryza sativa l.) is one of the iran's most strategic crops with water shortage as the most important abiotic stress limiting its yield. in the present research the effects of: variety, water regime, nitrogen (n) and phosphorus (p) levels on n, p and k uptake were studied under greenhouse conditions. the experiment design was a factorial one based upon a randomized complete blocks of ...
This study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by Azolla caroliniana. The experimental investigations have been carried out using Azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), pH (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). Th...
Background and Aim: Phytoremediation is a promising method for improving soils that can easily absorb heavy metals, resulting in decontamination of the soil. The objective of this study was to assess the phytoremediation potential of Alyssum maritimum in the remediation of lead-contaminated soil. Materials and Methods: A randomized complete block design was used with five levels of lead (Pb) c...
In order to investigate the effect of Cd and Zn on uptake, concentration and the translocation factor of the Cd and Zn in the rice plant, a factorial experiment was conducted with four factors including two rice cultivars of Vandana and Hashemi, two waterlogged and non-waterlogged conditions and three levels of Zn and Cd (0, 5 and 10 mg kg-1 soil). The experiment was carried out in a randomized...
