“…27 An exhaustive description of the quality assurance/quality control protocol was provided in our previous study. 25 The recoveries were 94 ± 5% for all of the metals in the plant reference materials (SRM1515, apple leaves). For the water-soluble Cu, 5 g of soils were placed in a 50 mL polypropylene centrifuge tube, followed by adding deionized water at a soil-to-water ratio of 1:5.…”

Cocontamination by heavy metals and persistent organic pollutants (POPs) is ubiquitous in the environment. Fate of POPs within soil/water-plant system is a significant concern and an area where much uncertainty still exists when plants suffered cotoxicity from POPs and metals. This study investigated the fate of polybrominated diphenyl ethers (PBDEs) when copper (Cu) was present within the soil/water-plant system using pot and hydroponic experiments. The presence of Cu was found to induce damage to the root cell membranes of corn (Zea mays L. cv. Nongda 108) with increasing concentration in both shoots and roots. The PBDE congeners BDE209 and BDE47 in shoots were also enhanced with the increasing electrolytic leakage from root, attributed to Cu damage, and the highest shoot BDE209 and BDE47 levels were observed under the highest Cu dosage. In addition, positive correlations were observed between the PBDE content of corn shoots and the electrolytic leakage of corn roots. These results indicated that within a defective root system, more PBDEs will penetrate the roots and are acropetally translocated in the shoots. The potential ecological risk associated with the translocation and accumulation of POPs into plant shoots needs careful reconsideration in media cocontaminated with metals and POPs, whereas often ignored or underestimated in environmental risk assessments.

“…However, limited publications are available on the distribution pattern of old and emerging flame retardants in vegetation from e-waste recycling sites, in particular for vegetables consumed by local residents. The uptake of persistent organic pollutants (POPs) from environmental matrices into plants has attracted considerable research interest, because it plays an important role in trapping and transferring POPs to terrestrial ecosystems, with a corresponding ecological risk (Luo et al, 2015). Soil-air-leaf and soil-root pathways are the two widely accepted routes for organic chemical uptake by plants, which have generally been described by the transpiration stream concentration factor and octanol-air or octanol-water partitioning (log K oa or log K ow ) (Limmer and Burken, 2014;Tian et al, 2012).…”
