The plant uptake of emerging organic contaminants such as pharmaceuticals and personal care products (PPCPs) is receiving increased attention. Biosolids from municipal wastewater treatment have been previously identified as a major source for PPCPs. Thus, plant uptake of PPCPs from biosolids applied soils needs to be understood. In the present study, the uptake of carbamazepine, diphenhydramine, and triclocarban by five vegetable crop plants was examined in a field experiment. At the time of harvest, three compounds were detected in all plants grown in biosolids-treated soils. Calculated root concentration factor (RCF) and shoot concentration factor (SCF) are the highest for carbamazepine followed by triclocarban and diphenhydramine. Positive correlation between RCF and root lipid content was observed for carbamazepine but not for diphenhydramine and triclocarban. The results demonstrate the ability of crop plants to accumulate PPCPs from contaminated soils. The plant uptake processes of PPCPs are likely affected by their physico-chemical properties, and their interaction with soil. The difference uptake behavior between plant species could not solely be attributed to the root lipid content.
植物对新兴有机污染物（如药品和个人护理产品[PPCPs]）的吸收受到了越来越多的关注。城市废水处理产生的生物固体以前被确定为 PPCPs 的主要来源。因此，需要了解植物从施用于土壤的生物固体中吸收 PPCPs 的情况。在本研究中，在田间试验中研究了五种蔬菜作物对卡马西平、苯海拉明和三氯生的吸收。在收获时，所有在生物固体处理过的土壤中生长的植物中都检测到了这三种化合物。计算的根浓度系数（RCF）和茎浓度系数（SCF）以卡马西平最高，其次是三氯生和苯海拉明。卡马西平的 RCF 与根脂含量呈正相关，但苯海拉明和三氯生则没有。研究结果表明，作物植物有从受污染土壤中积累 PPCPs 的能力。PPCPs 的植物吸收过程可能受到其物理化学性质以及它们与土壤的相互作用的影响。植物物种之间吸收行为的差异不能仅仅归因于根脂含量。
