“…Therefore, it is likely that specific leaf area is a more important factor in controlling the air-plant exchange of SOCs than leaf surface area. In addition, leaf lipid also plays an important role in the exchange, as suggested by previous studies (Simonich and Hites, 1995b;Lin et al, 2007).…”

“…Subsequently the BDE-28 concentration in the solution continued to decrease and reached 0.57 ng/mL, while BDE-47 had a slight decrease and BDE-99 showed almost no change. Root concentration factors (RCFs), calculated as the ratio of the concentration in roots to that in the exposure solution (Trapp, 2000), were 4003.8, 6410.2 and 7304.1 for BDE-28, -47 and -99 respectively after one day of exposure, confirming the higher root uptake of compounds with higher K ow values (Burken and Schnoor, 1998;Lin et al, 2007;Liu and Schnoor, 2008).

Uptake, translocation and debromination of three polybrominated diphenyl ethers (PBDEs), , in maize were studied in a hydroponic experiment. Roots took up most of the PBDEs in the culture solutions and more highly brominated PBDEs had a stronger uptake capability. PBDEs were detected in the stems and leaves of maize after exposure but rarely detected in the blank control plants. Furthermore, PBDE concentrations decreased from roots to stems and then to leaves, and a very clear decreasing gradient was found in segments upwards along the stem. These altogether provide substantiating evidence for the acropetal translocation of PBDEs in maize. More highly brominated PBDEs were translocated with more difficulty. Radial translocation of PBDEs from nodes to sheath inside maize was also observed. Both acropetal and radial translocations were enhanced at higher transpiration rates, suggesting that PBDE transport was probably driven by the transpiration stream. Debromination of PBDEs occurred in all parts of the maize, and debromination patterns of different parent PBDEs and in different parts of a plant were similar but with some differences. This study for the first time provides direct evidence for the acropetal translocation of PBDEs within plants, elucidates the process of PBDE transport and clarifies the debromination products of PBDEs in maize.

“…In set II experiments micro-organisms were present, whereas in set I experiments 8 micro-organisms presence was markedly reduced (results not shown). Therefore, the elutriates 9 with measurable PAHs levels had a much lower microbial population than the other 10 conditions, but even in these cases PAH concentrations were much lower than the dosed could also be adsorbed on the root surface or absorbed into root tissues (Lin et al, 2007) ). 17 However, in the current study it is not possible to determine the exact causes contributing to 18 the removal of PAHs from solution.…”
