摘要

The global presence of pharmaceuticals in the environment has been particularly considered a concerning problem with unknown consequences. Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most frequently prescribed drugs in the world, and as a result, they are commonly found in different environmental compartments. In the present work, we studied the effects of NSAIDs (diclofenac, ibuprofen, and naproxen) on the composition and ultrastructure of Atriplex patula L., S. oleracea, and Lactuca sativa L., three green leafy vegetables with significant nutritional value. Contaminant solutions of NSAIDs were applied every two days using concentrations of 0.1 mg L-1, 0.5 mg L-1, and 1 mg L-1. After eight weeks of exposure of the green leafy vegetables to the selected NSAIDs, the chlorophylls (a + b), carotenoids (zeaxanthin, lutein, and beta-carotene), total polyphenol and total flavonoid contents, antioxidant capacity, and the ultrastructural modifications were determined. The obtained results indicated a moderate reduction in the assimilating pigments, total polyphenol and flavonoid contents. In addition, ultrastructural damages of the chloroplasts and cell walls were observed in the leaves of the selected vegetables, which were exposed to abiotic stress-induced by NSAIDs. All data collectively suggest that this group of drugs induced harmful effects on plants, and implicitly they may also negatively affected human health on the long term.

Oleracea和Lactuca Sativa L.,三种绿叶蔬菜具有显着营养价值的组成和超微结构的影响。每两天使用0.1mg L-1,0.5mg L-1和1mg L-1每两天施加NSAID的污染物溶液。在将绿叶蔬菜暴露八周后,叶绿素(A + B),类胡萝卜素(ZeAxanthin,叶黄素和β-胡萝卜素),总多酚和总黄酮含量,抗氧化能力和超微结构改性决定。所得结果表明同化颜料,总多酚和类黄酮含量的中等还原。此外,在所选蔬菜的叶片中观察到叶绿体和细胞壁的超微结构损伤,该蔬菜的叶子暴露于NSAIDs的非生物胁迫。所有数据集体都表明,这群药物对植物产生了有害影响,并隐含地影响人类健康的长期。
