Abstract

Many pharmaceutical and personal care products (PPCPs) and endocrine-disrupting chemicals (EDCs) are present in reclaimed water, leading to concerns of human health risks from the consumption of food crops irrigated with reclaimed water. This study evaluated the potential for plant uptake and accumulation of four commonly occurring PPCP/EDCs, i.e., bisphenol A (BPA), diclofenac sodium (DCL), naproxen (NPX), and 4-nonylphenol (NP), by lettuce (Lactuca sativa) and collards (Brassica oleracea) in hydroponic culture, using (14)C-labeled compounds. In both plant species, plant accumulation followed the order of BPA > NP > DCL > NPX and accumulation in roots was much greater than in leaves and stems. Concentrations of (14)C-PPCP/EDCs in plant tissues ranged from 0.22 ± 0.03 to 927 ± 213 ng/g, but nearly all (14)C-residue was non-extractable. PPCP/EDCs, particularly BPA and NP, were also extensively transformed in the nutrient solution. Dietary uptake of these PPCP/EDCs by humans was predicted to be negligible.

摘要

许多药品和个人护理产品(PPCPs)以及内分泌干扰化学物质(EDCs)存在于再生水中,这引起了人们对人类健康因食用再生水灌溉的农作物而面临风险的担忧。本研究通过水培实验,评估了生菜(Lactuca sativa)和羽衣甘蓝(Brassica oleracea)对四种常见的 PPCP/EDCs(双酚 A(BPA)、二氯芬酸钠(DCL)、萘普生(NPX)和 4-壬基酚(NP))的植物吸收和积累的潜力,实验中使用了(14)C 标记化合物。在这两种植物中,植物的积累顺序为 BPA > NP > DCL > NPX,且根部的积累量远大于叶片和茎部。植物组织中(14)C-PPCP/EDCs 的浓度范围为 0.22 ± 0.03 至 927 ± 213 ng/g,但几乎所有(14)C 残留均不可提取。PPCP/EDCs,特别是 BPA 和 NP,在营养液中也被广泛转化。预测这些 PPCP/EDCs 通过饮食被人类摄入的量可忽略不计。
