“…Co-existence of Cd and PCP is of great concern due to their persistence; potentially carcinogenic properties; and their acute toxicity (Hechmi et al 2013). Thus, the cleanup of Cd and PCP contaminated soils is emergent and imperative and it is critical to develop efficient approaches to simultaneously remove multiple contaminants from soils.…”

Despite many studies on phytoremediation of soils contaminated with either heavy metals or organics, little information is available on the effectiveness of phytoremediation of co-occurring metal and organic pollutants especially by using wetland species. Phragmites australis is a common wetland plant and its potential for phytoremediation of cadmium pentachlorophenol (Cd-PCP) co-contaminated soil was investigated. A greenhouse study was executed to elucidate the effects of Cd (0, 10, and 20 mg kg(-1)) without or with PCP (0, 50, and 250 mg kg(-1)) on the growth of the wetland plant P. australis and its uptake, accumulation and removal of pollutant from soils. After 75 days, plant biomass was significantly influenced by interaction of Cd and PCP and the effect of Cd on plant growth being stronger than that of PCP. Coexistence of PCP at low level lessened Cd toxicity to plants, resulting in improved plant growth and increased Cd accumulation in plant tissues. The dissipation of PCP in soils was significantly influenced by interactions of Cd, PCP and plant presence or absence. As an evaluation of soil biological activities after remediation soil enzyme was measured.

“…The plant root exudates by counteracting toxicity of the substances which would also provide proper conditions for a better plant growth (Hechmi et al, 2013). So, any action such as adding soil amendments or conditioners to petroleum contaminated soil could enhance and increase the rate and quality of remediation efficacy of the plants like soybean or maize (Njoku et al, 2008).…”

Petroleum and petrochemical hydrocarbons for some places are serious sources of environmental pollutants. To remediate these contaminants, phytoremediation, a relatively low cost and an environmental friendly technique is recommended more widely, now more than ever. Successful and effective applying of hydrocarbons phytoremediation depends mainly on the soil and plant types and conditions and microbial activities and the interactions between these three factors. Although for the last several decades, various plant and organism's species for the phytoremediation processes have been extensively studied, evaluating and characterizing soil properties, as an important objective for sustainable remediation and land use management, which had negligible considerations. An ideal soil for phytoremediation should have proper physical, chemical and biological characteristics to let the plant grow well and produce biomass as high as possible. It also should provide favorable conditions for microbial activities to perform efficient remediation. Soil physical characteristics such as texture, structure, water status and aeration are important factors affecting the microbial activities and consequently the degree of remediation potential. A better understanding of soil physical properties in conjunction with proper soil-plant-microbe management could be exploited to enhance the remediation of hydrocarbon contaminated soils and thus sustainable healthy environment.

“…Phytostabilisation has proved to be useful for the treatment of Pb, As, Cd, Cr, Cu and Zn contaminated soils 9 . Phytoremediation is a very complex biotechnology, which is under the significant influence of (I) plant morphology (growth rate, biomass yields) and physiology (accumulation potential, stress tolerance) 14,15 , (II) agro-ecological conditions of cultivated land (soil type and environment) [16][17][18] , (III) agronomy practices (cultivars, planting density, soil amendments application) [19][20][21] , (IV) origin of contamination [22][23][24] . To increase the potential of phytoremediation, which is usually limited by low above ground biomass and/or a shallow root system [25][26][27] more and more attention has been given to perennial plants with high biomass yield potential 20,28 .…”

The determination of the effects of cadmium and mercury on the growth, biomass productivity and phytoremediation potential of Miscanthus × giganteus (MxG) grown on contaminated soil was the main aim of this paper. the use of bioenergy plants as an innovative strategy in phytotechnology gives additional benefits, including mitigation and adaptation to climate change, and soil remediation without affecting soil fertility. An experiment was set up as a randomized complete block design with the treatments varied in concentrations of Cd (0, 10 and 100 mg kg −1 soil) and Hg (0, 2 and 20 mg kg −1 soil) added to the soil. Three vegetative years were studied. Yield values ranged from 6.3-15.5 t DM ha −1 , cadmium concentration in plants varied from 45-6758 µg kg −1 and Hg varied from 8.7-108.9 µg kg −1 . Values between treatments and years were significantly different. MxG can accumulate and remove very modest amount (up to 293.8 µg Cd and 4.7 µg Hg) per pot per year in aboveground biomass. Based on this data it can be concluded that MxG, as a valuable energy crop, is a potential candidate for the phytostabilization and biomass production on soils contaminated with Cd and Hg moderately.Phytoremediation is considered as a simple and a natural technology that uses plants which can be utilize for efficient absorption of pollutants from contaminated soils 1,2 . Generally, remediation of heavy metal polluted soils could be classified as physico-chemical and biological remediation techniques 3 . Compared to physico-chemical techniques (vitrification, soil washing, solidification and stabilization), phytoremediation technology could reduce dust emission, risk of exposure to soil, provide erosion control and prevent runoff 4 . Unlike physical and chemical treatments that irreversibly alter soil properties, phytoremediation generally improves physical, chemical, and biological quality of contaminated soils, improving soil quality and functionality and carbon sequestration 5,6 . Phytoremediation is suitable for different types of contaminants (organic, metals and radionuclides), with relatively low financial costs, does not require additional energy delivery (energy is obtained from solar radiation) and with minimally influence to the site destruction and destabilization. Additionally, it contributes to the improvement of the visual aspect of the landscape, provides habitats for animals, and reduces leaching and mobilization of contaminants in soil 7 . Disadvantages of phytoremediation include: long remediation time requirement (the process is slow and requires 3-20 growing seasons to achieve remediation goals); relatively shallow cleaning depths; potentially contamination of the food chain; a site-specific technology (structure of the soil profile, pH, presence of salt or other toxins, water quality including nutrients, oxygen content) with a choice of plants being critical, and the fate of contaminants often unclear (the technology may relocate contaminants from the subsurface to the plant, creating residual waste to be disposed ...
