| 英文摘要 | Polybrorrtiriated diphenyl ethers (PBDEs), methoxylated PBDEs (MeO-PBDEs), and hydroxylated PBDEs (OH-PBDEs) ate widely found in various environmental media, which is of concern given their biological toxicity. In this study, the phytotoxicities of BDE47, 6-MeO7BDE.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- CAT 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-Meb-BDE-47, and 6-OH-BDE-47 caused the overproduction of H2O2, O-2(center dot-) and center dot 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 BD-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. |
