“…In order to compare their uptake abilities, root concentration factors (RCFs) were calculated as the ratio of the concentrations in maize roots to the concentrations in the exposure solutions. The average RCF values were in the following order: BDE- 47 > 6-MeO-BDE-47 > 6-OH-BDE-47, which was consistent with the previous observations in field contamination investigations (Sun et al, 2013b;Wang et al, 2014). A significant positive correlation existed between the values of logRCF and logK ow (R 2 ¼ 0.91, p < 0.0001) (Fig.…”

“…Therefore, a hydroponic experiment was conducted although it cannot entirely exclude the influences from root-associated microbes. BDE-47 is frequently detected in PBDE-contaminated soils and accumulated in plants at relatively high concentrations (Kim et al, 2014;Sun et al, 2013b). So, BDE-47 and its hydroxylated and methoxylated analogs (6-OH-BDE-47 and 6-MeO-BDE-47) were selected as the target compounds, and their kinetic uptake by roots and acropetal translocation in maize were investigated.…”

“…Seafood consumption were considered to contribute to the load of OH-PBDEs in biosolids in wastewater treatment plants (Sun et al, 2012b). Seafood processing factory and seafood market have been found as important sources that MeO-and OH-PBDEs entered soil and plants (Sun et al, 2013). Consumption of marine products could represent an important source of OH-PBDEs and MeO-PBDEs exposure for humans.…”

h i g h l i g h t sOH-PBDEs and MeO-PBDEs were determined in mollusks from Chinese coastal areas. Significant correlations were found between OH-and MeO-PBDEs. Crassostrea talienwhanensis accumulated more OH-and MeO-PBDEs. Temporal trends of OH-and MeO-PBDEs in mollusks were studied. a r t i c l e i n f o between OH-and MeO-PBDEs, but neither between PBDEs and OH-PBDEs, nor between PBDEs and MeO-PBDEs, suggesting that OH-and MeO-PBDEs may have a common source or similar accumulation behavior in mollusks. OH-and MeO-PBDEs were likely not to originate from PBDE precursors.

Polybrominated diphenyl ethers (PBDEs), methoxylated PBDEs (MeO-PBDEs), and hydroxylated PBDEs (OHPBDEs) are widely found in various environmental media, which is of concern given their biological toxicity. In this study, the phytotoxicities of BDE-47, 6-MeO-BDE-47, and 6-OH-BDE-47 to maize (Zea mays L.) were investigated by an in vivo exposure experiment. Results showed that BDE-47, 6-MeO-BDE-47, and 6-OH-BDE-47 inhibited seed germination and seedling development, and elevated malondialdehyde (MDA), carbonyl groups, and phosphorylated histone H2AX levels in maize roots, suggesting the inducement of lipid peroxidation, protein carbonylation, and DNA damage to maize. Exposure to BDE-47, 6-MeO-BDE-47, and 6-OH-BDE-47 caused the overproduction of H 2 O 2 , O 2•− , and •OH, and elevated the activities of antioxidant enzymes in the roots. In addition, 6-OH-BDE-47 caused more severe damage and reactive oxygen species (ROS) generation in maize than did BDE-47 and 6-MeO-BDE-47. These results demonstrated the phytotoxicities of BDE-47, 6-OH-BDE-47, and 6-MeO-BDE-47 to maize, and clarified that overproduction of ROS was the key mechanism leading to toxicity. This study offers useful information for a more comprehensive understanding of the environmental behaviors and toxicities of PBDEs, MeO-PBDEs, and OH-PBDEs.
