| Description | Uptake of C-14-labeled fluoranthene ([C-14]FLT) via both roots and leaves of Pisum sativum seedlings and distribution of [C-14] in plants by both acropetal and basipetal transport was evaluated. The highest [C-14] level was found in the root base (approximate to 270x10(4) dpm/g dry wt) and the lowest level in the stem apex (<2x10(4) dpm/g dry wt) after just 2h of root exposure. For foliar uptake, the highest level of [C-14] was found in the stem and root apex (both approximate to 2x10(4) dpm/g dry wt) (except for treated leaves), while the lowest level was found in the root base (<0.6x10(4) dpm/g dry wt). |
