Uptake of (14)C-labeled fluoranthene ([(14)C]FLT) via both roots and leaves of Pisum sativum seedlings and distribution of [(14) C] in plants by both acropetal and basipetal transport was evaluated. The highest [(14)C] level was found in the root base (≈270 × 10(4) dpm/g dry wt) and the lowest level in the stem apex (<2 × 10(4) dpm/g dry wt) after just 2 h of root exposure. For foliar uptake, the highest level of [(14)C] was found in the stem and root apex (both ≈2 × 10(4) dpm/g dry wt) (except for treated leaves), while the lowest level was found in the root base (<0.6 × 10(4) dpm/g dry wt).
评估了豌豆幼苗的根和叶对（14）C标记的荧蒽（[（14）C]FLT）的吸收情况，以及通过向顶运输和向基运输在植物中[（14）C]的分布。根部暴露仅2小时后，在根部基部发现了最高的[（14）C]水平（约270×10⁴ dpm/g干重），而在茎尖发现了最低水平（<2×10⁴ dpm/g干重）。对于叶面吸收，在茎和根尖（两者均约为2×10⁴ dpm/g干重）（处理过的叶片除外）发现了最高的[（14）C]水平，而在根部基部发现了最低水平（<0.6×10⁴ dpm/g干重）。
