  • Phytoremediation - II

    Introduction: Phytoremediation is a set of processes that uses plants to clean contamination in ground water and surface water. There are several ways plants can be used for the phytoremediation. These mechanisms include enhanced rhizosphere biodegradation, hydraulic control, phyto-degradation and phyto-volatilization. Enhanced Rhizosphere Biodegradation Enhanced ...

  • Phytoremediation - I

    Introduction Phytoremediation is a process that uses plants to remove, transfer, stabilize, and destroy contaminants in soil and sediment. The mechanisms of phytoremediation include enhanced rhizosphere biodegradation, phyto-extraction (also called phyto-accumulation), phyto-degradation, and phyto-stabilization. Enhanced Rhizosphere Biodegradation Enhanced ...

  • Phytoremediation - Technology Overview

    ABSTRACT Phytoremediation uses plants to cleanup contaminated soil and groundwater, taking advantage of plants' natural abilities to take up, accumulate, and/or degrade constituents of their soil and water environments. Results of research and development into ph ytoremediation processes and techniques report it to be applicable to a broad range of contaminants including numerous metals and ...


  • Screening of few aquatic floating plants for chromium phytoremediation

  • Phytoremediation of mercury using Eichhornia crassipes (Mart.) Solms

    Roots of Eichhornia crassipes were found to accumulate maximum content of mercury (92.21 μg g−1 dry wt) in the roots of plants treated with 1000 μg l−1 concentration of mercuric acetate on 14th day of treatment. The bioconcentration factor (BCF) was found to be highest for lowest mercury concentrations ...

  • Coupling vermiremediation with phytoremediation technology to enhance the efficiency of reclamation of polluted marine sediments

    Contaminated (TPHs and heavy metals) dredged sediments from Livorno port (Italy) were biological treated using plants and earthworms. Sediments presented an asphyctic physical structure owing to the silt?clay granulometric composition, a high salty level and a low organic content. A meso-scale experiment was done utilising three different bioremediation treatments: a) plants (Paspalum vaginatum ...

  • Phytoremediation of Alkylated Polycyclic Aromatic Hydrocarbons in a Crude Oil-Contaminated Soil

    Abstract  Phytoremediation uses plants and their associated microorganisms in conjunction with agronomic techniques to remove or degrade environmental contaminants. The objective of the field study was to evaluate the effect of vegetation establishment plus fertilizer addition on the biodegradation of alkylated polycyclic aromatic hydrocarbons in a crude oil-contaminated soil. Four ...


  • Phytoremediation technology for wastewater treatment: high rate transpiration system

    High Rate Transpiration System (HRTS) is a well-designed land treatment system composed of ridges and furrows and well-controlled hydraulic loading of wastewater. The present case study describes long-term operating experience of zero discharge of pulp and paper mill wastewater, which is characterised by high BOD, COD, TDS and colour that poses disposal problems into water bodies and on land. The ...

  • Microbe-assisted phytoremediation approach for ecological restoration of zinc mine spoil dump

    Mining is one of the sectors that impacts air, water and soil pollution. The various environmental problems that are associated with mining activities are deforestation, removal of fertile topsoil, unstable slopes prone to sliding and erosion, siltation of water bodies due to wash off of mineral overburden dumps, air pollution due to discharge of dust and noise pollution. The most effective means ...

  • Assessment Of Tropical Grasses And Legumes For Phytoremediation Of Petroleum-Contaminated Soils

    Phytoremediation is a promising technology for the clean-up of petroleum-contaminated soils, especially in the tropics where climatic conditions favour plant growth and microbial activity and where financial resources can be limited. The objective of this work was to identify tropical plant species from the eastern savannahs of Venezuela suitable for this technology. Three legumes (Calopogonium ...

  • Utilisation of municipal solid waste as an amendment for reclamation of coal mine spoil dump

    Mine spoil dumps generated due to mining activities pose drastic physico-chemical and biological constraints for sustainable vegetation. Thus an eco-friendly and cost-effective Microbe Assisted Phytoremediation (MAP) is adopted for reclamation of coalmine spoil dumps. The results indicate that MAP is also an excellent tool for fast restoration and productivity of wastelands, 95?99% plants ...

  • Common Treatment Train for Inorganics

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for inorganics is illustrated below. Metal contaminated soil is treated using the combination of electrokinetics and phytoremediation. Electrokinetics is used to remove metals from deep soil and ground water. A low density direct current is applied to mobilize charged species, ...

  • Cadmium in soil-plant systems: an overview

    High concentrations of cadmium in soils represent a potential threat to human health because it is incorporated in the food chain mainly by plant uptake. The behaviour of cadmium in soils depends on several factors related to both soil and plant characteristics. This paper provides an overview of such factors as well as of the most environmentally friendly in situ soil remediation techniques in ...

  • The Influence of an Integrated Remedial System on Groundwater Hydrology

    ABSTRACT This paper summarizes the development of a remedial system designed to hydraulically contain and ultimately reduce a plume consisting of primarily 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA). The system consists of groundwater circulating wells or extraction wells located in the core of the 1,1,2,2-TeCA plume to provide active source control, combined with monitored natural attenuation ...
