Role of Rhizoremediation in Decontaminating Some Hazardous Pollutants

Abstract

Rhizoremediation is a natural biological base, multifactorial operation treatment method which highly depends to environmental factors especially in terrestrial environment as operation of remediation process. Interaction and relationship between microbial community and plant roots is specific attraction and advantages of this advanced treatment method. Decontamination efficiency and time could be highly manageable by operation and rhizoaugmentation. Rhizoremediation is advanced compact combination of phytoextraction, phytovolatilization, phytotransformation and phytostabilization. High efficiency of pollutants removal, adaptive and wide range of operation and augmentation factors cause of emerging application of this for biodegradable organic compounds and heavy metals. Selection of suitable plant and joining them with comfortable microbial couples is a function which can plane simultaneously removal system. This chapter will present an overview on PAH, TPH, PCB and heavy metal removal and mechanism of decontamination, plant selection and augmentation process.

Phytoremediation: green technology for improving aquatic and terrestrial environments

“…This type of phytoremediation is going to be a major part of phytoremediation and nowadays have high concerning by scientists and research groups for both biodegradable and non-biodegradable pollutants. Rhizoremediation could be an advanced compact combination of phytoextraction, phytovolatilization, phytotransformation and phytostabilization (Farraji et al, 2017).…”

Plant-bacteria synergism: An innovative approach for the remediation of crude oil-contaminated soils

“…Soils contaminated with elevated amounts of crude oil are often deficient in nitrogen. Legumes might be utilized in phytoremediation because of their symbiotic-association with nitrogen fixers (bacteria and fungi) and arbuscularmycorrhizal fungi (Farraji et al, 2017;McIntosh et al, 2017). The root system of leguminous plants generally is not as flourished as grasses to reach deeper soil layers (Safronova et al, 2011).…”

“…Common factors for selection of trees or grasses generally include: 1) resistance to contaminants, 2) tolerance to environmental conditions, 3) high productivity, 4) low bioaccumulation, 5) suitability for various soil types, and 6) native to avoid the introduction of invasive species. Several reports indicated that shrubs, grasses, herbs and trees are suitable candidates that can be utilized for phytoremediation (Farraji et al, 2017;Patel and Patra, 2017;Singha and Pandey, 2017;Shahsavari et al, 2016). Legumes (e.g.…”
