“…On the other hand, indigenous functional microbes might be capable of degrading PBDEs after being acclimated for a long time. For example, the microbial degradation of BDE-47 was accelerated in RS due to the increased abundance of bacteria in the rhizosphere (Chen et al, 2015). In addition, the biotransformation of higher-brominated PBDE (e.g., congeners to lower-brominated PBDE congeners (e.g., BDE-47) occurs naturally in the environment (Gandhi et al, 2011).…”

Especially, the enhanced microbial degradation either aerobically or anaerobically initiated by rhizosphere effect was reported to be the key process underpinning the facilitated removal of OCs from polluted soils (Zhu et al, 2014;Chen et al, 2015). The beneficial effect is also plant-specific, due to the contrasting root secretion, particularly in different aerobic and anaerobic conditions.…”

An experiment was conducted to improve rhizoremediation for decabromodiphenyl ether (BDE-209) contaminated soil from typical E-waste dismantling areas. Plants of ryegrass (Lolium perenne L.) and rice (Oryza sativa L.) were cultivated in aged-contaminated (initial concentration of 346.3 µg BDE-209$kg-1) and freshly-spiked (initial concentration of 3127 µg BDE-209$kg-1) soils, coupling with the agricultural modification strategies of compost addition and/or arbuscular mycorrhizal fungi (AMF) infection, respectively. 60 days' growth of ryegrass significantly facilitated the dissipation of BDE-209, with the most effective in its rhizosphere in treatment inoculated with AMF; the BDE-209 dissipation rates achieved 51.9% and 22.8% in rhizosphere, and 43.5% and 19.8% in non-rhizosphere, for aged-contaminated and freshlyspiked soils, respectively. 120 days' growth of rice with simultaneous inoculation of AMF and addition of compost was the most effective in facilitating BDE-209 dissipation in agedcontaminated soil, with the removal rates of 53.3% and 48.1% in rhizosphere and nonrhizosphere soils respectively; while for freshly-spiked soils, the most effective removal was achieved by compost addition only, with the BDE-209 dissipation rates of 27.9% and 26.6% in rhizosphere and non-rhizosphere soils, respectively. High throughput sequencing analysis of rhizosphere soil DNA showed that responses in microbial communities and their structure differed with plant species, soil pollution dose, AMF inoculation and/or compost addition. Actinomycetales, Xanthomonadales, Burkholderiales, Sphingomonadales, Clostridiales, Cytophagales, Gemmatimonadales and Saprospirales were the sensitive responders and even possibly potential functional microbial groups during the facilitated removal of BDE-209 in soils. This study illustrates an effective rhizoremediation pattern for removal of BDE-209 in pollution soils, through successive cultivation of rice and followed by ryegrass, with rice growth coupled with AMF inoculation and compost addition, while ryegrass growth coupled with AMF inoculation only.

“…Bacterial debromination of PBDEs in soil and sediments was shown by different authors (Chen et al 2015(Chen et al , 2017Farzana et al 2019b;Hale et al 2012;Wang et al 2020;Zhao et al 2017b;Zhu et al 2014b, c). Transformation intermediates of BDE-153 (Br 6 ) were analyzed by Zhu et al in eight different sediments revealing formation of lower brominated transformation products (Br 1 -Br 6 ) under anaerobic conditions and, contrarily, negligible transformation under aerobic conditions (Zhu et al 2014b).…”

Polybrominated diphenyl ethers (PBDEs) have widely been used for decades as flame retardants in a variety of products like plastics for building insulation, upholstered furniture, electrical appliances, vehicles, aircrafts, polyurethane foams, textiles, cable insulation, appliance plugs and various technical plastics in concentrations of 5–30%. However, PBDEs also act as endocrine disrupters, neurotoxins, and negatively affect fertility. In 2001, worldwide consumption of technically relevant penta-BDEs was still estimated at 7500 tons, octa-BDEs at 3790 tons, and deca-BDE at 56,100 tons, but 50–60% of this total volume are discharged into the environment via sewage sludge and its agricultural use alone. In addition, soils are ubiquitously contaminated by the gaseous or particle-bound transport of PBDEs, which today has its main source in highly contaminated electronic waste recycling sites. The emitted PBDEs enter the food chain via uptake by the plants’ roots and shoots. However, uptake and intrinsic transport behaviour strongly depend on crop specifics and various soil parameters. The relevant exposure and transformation pathways, transport-relevant soil and plant characteristics and both root concentration factors (RCF) and transfer factors (TF) as derivable parameters are addressed and quantified in this review. Finally, a simple predictive model for quantification of RCF and TF based on log KOW values and the organic content of the soil/lipid content of the plants is also presented.
