“…At these e-waste recycling sites the highest BDE-209 concentration levels ever listed were described by Han et al (2017), namely 6.3-12,194.6 ng g DM -1 at a ratio of 64.2-89.6% of the total PBDE ( P PBDE). At levels of 2720-4250 ng g DM -1 of P PBDE at a BDE-209 ratio of 35-82% and at P PBDE levels up to 2000 ng g DM -1 similar concentration levels were previously described (Leung et al 2007;Zhang et al 2015). Moreover, the currently highest P PBDE levels in soil were quantified as 8.70-18,451 ng g DM -1 by Xu et al (2019) at a production site for plastic parts in electrical industry in Changzhou.…”

“…As a conclusion and in difference to PCBs, there is a strong negative correlation of the log K OW value and the RCF, i.e. higher RCF values were detected in case of lower brominated PBDEs and, therefore, compounds with lower log K OW values than in case of higher log K OW values (Zhang et al 2015). In detail, the plant specific RCF of BDE-209 was up to ten times lower than the RCF of BDE-28 (Han et al 2017;She et al 2013;Zhang et al 2015).…”

“…higher RCF values were detected in case of lower brominated PBDEs and, therefore, compounds with lower log K OW values than in case of higher log K OW values (Zhang et al 2015). In detail, the plant specific RCF of BDE-209 was up to ten times lower than the RCF of BDE-28 (Han et al 2017;She et al 2013;Zhang et al 2015). This effect may be explained both by the lack of water solubility and, therefore, restricted root uptake with the soil moisture phase, and the strong adsorption of higher brominated PBDE on the soil phase.…”

“…Hence, this pathway is of low relevance but still present as shown by BDE-209 levels 3.5-6 times higher in living roots of different plants than in nonliving samples (Chow et al 2017) or by small-scale soil based BDE gradients within the root zone (Száková et al 2019). BDE-209 uptake by roots even might be the dominant pathway at high soil contamination levels or hydroponic cultivation (Zhang et al 2015). This statement was clearly evidenced by greenhouse experiments of Huang et al (Huang et al 2010).…”

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.

“…The beneficial effect is also plant-specific, due to the contrasting root secretion, particularly in different aerobic and anaerobic conditions. So far, various plant species have been tested for the potential functional species with high efficiency in pollution remediation of typical OCs, such as PBDEs, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and pentachlorophenol (PCP), including the xerophyte species such as maize, ryegrass, tall fescue, lettuce and the hygrocolous species such as rice, zucchini (Huang et al, 2010;Wang et al, 2011a;Inui et al, 2011;Kuo et al, 2014;Wang et al, 2014;Qin et al, 2014;He et al, 2015;Zhang et al, 2015;Bizkarguenaga et al, 2016). As for PBDEs, the ryegrass (Lolium perenne L.) and the rice (Oryza sativa L.) cultivars (Xiushui 134) were recommended as the most functional plant species for a cost-effective remediation of soils polluted by BDE-209 around an e-waste recycling area by a screening experiment coupling with regulation of soil redox status during plant growth (He et al, 2015).…”

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.
