“…Our recent study investigated the translocation of PBDEs within plants in a national nature reserve and found that TF decreased with increasing the log K ow . 22 However, the translocation behaviors of PBDEs were different in the rice, and TF increased with increasing the log K ow . 23 These controversial results implied that the uptake and translocation processes have not been well disclosed for PBDEs in plants solely by using the physicochemical properties of targets.…”

The uptake, translocation, and transformation of 2,2′,4,4′-tetra brominated diphenyl ether (BDE-47) in wheat (Triticum aestivum L.) were comprehensively investigated by hydroponic experiments using compound-specific stable isotope analysis (CSIA) and transcriptome analysis. The results indicated that BDE-47 was quickly adsorbed on epidermis of wheat roots and then absorbed in roots via water and anion channels as well as an active process dependent on energy. A small fraction of BDE-47 in roots was subjected to translocation acropetally, and an increase of δ 13 C values in shoots than roots implied that BDE-47 in roots had to cross at least one lipid bilayer to enter the vascular bundle via transporters. In addition, accompanied by the decreasing concentrations, δ 13 C values of BDE-47 showed the increasing trend with time in shoots, indicating occurrence of BDE-47 transformation. OH-PBDEs were detected as transformation products, and the hydroxyl group preferentially substituted at the ortho-positions of BDE-47. Based on transcriptome analysis, genes encoding polybrominated diphenyl ether (PBDE)-metabolizing enzymes, including cytochrome P450 enzymes, nitrate reductases, and glutathione S-transferases, were significantly upregulated after exposure to BDE-47 in shoots, further evidencing BDE-47 transformation. This study first reported the stable carbon isotope fractionation of PBDEs during translocation and transformation in plants, and application of CSIA and transcriptome analysis allowed systematically characterize the environmental behaviors of pollutants in plants.

This study aims to develop and validate a robust analytical method for the quantification of polybrominated diphenyl ethers (PBDEs) in human serum using gas chromatography–tandem mass spectrometry. We compared procedural blanks, recoveries, and operational convenience of liquid–liquid extraction and supported liquid extraction for the determination of serum PBDEs. We evaluated different extraction solvents for their effect on PBDE recoveries. Supported liquid extraction was selected for method validation due to its operational convenience. The method demonstrated satisfactory linearity, sensitivity, and reproducibility, with the range of 0.10–5.00 µg/L for most PBDE congeners and 0.20–10.0 µg/L for PBDE‐154 and PBDE‐183, with limits of detection ranging from 2 to 48 ng/L, and with matrix effects ranging from 94% to 113%. Quality control assessments indicated that recoveries ranged from 85% to 110% and relative standard deviations of less than 11%. The proposed method was applied to biomonitoring of 111 healthy adults, revealing detectable levels of PBDEs in over 90% of the samples. BDE‐47 and BDE‐183 were the most prevalent, with mean concentrations of 4.13 and 22.1 ng/L, respectively. Detection frequencies ranged from 0.90% for BDE‐17 and BDE‐85 to 25.2% for BDE‐47. Males had higher mean concentrations of BDE‐183 than females.
