Abstract Large scale productions made by industries to meet the needs of the ever growing human population has led to the contamination of environmental resources such as water, air, soil and forests. These contaminants pose health risks to humans and they are capable of entering the food chain through aquatic organisms and by the uptake in plants. This study investigated the uptake of alkylphenols, hormones, pesticides and bisphenol A by plants grown in soilless media under laboratory conditions. Green onion and lettuce were selected for this purpose due to their high water intake rate. Optimum parameters of a dispersive liquid-liquid microextraction method were applied to aqueous samples to lower detection limits for the analytes determined by gas chromatography mass spectrometry. Analysis performed on the plant media on alternate days suggested migration of the analytes into the plants and this was confirmed by results (0.59–6.4 μg/g) obtained for analyzed plant samples at the end of the study. The plants were then treated in simulated gastric and intestinal conditions, and the results obtained suggested degradation of the analytes with time. This is the first comprehensive study on the migration of different environmental contaminants into plants and the changes they undergo when ingested into the stomach.

植物中农药、激素和内分泌干扰化合物的吸收和生物可及性的可行性研究,以及胃和肠道状况的模拟

摘要 工业为满足不断增长的人口需求而进行的大规模生产导致了水、空气、土壤和森林等环境资源的污染。这些污染物对人类健康构成威胁,它们能够通过水生生物和植物吸收进入食物链。本研究调查了在实验室条件下在无土培养基中生长的植物对烷基酚、激素、杀虫剂和双酚 A 的吸收。选择大葱和生菜是因为它们的吸水率高。将分散液-液微萃取方法的最佳参数应用于水性样品,以降低气相色谱质谱法测定的分析物的检测限。隔天对植物培养基进行的分析表明,分析物迁移到植物中,研究结束时分析的植物样品的结果 (0.59–6.4 μg/g) 证实了这一点。然后在模拟的胃和肠道条件下处理植物,所得结果表明分析物随时间降解。这是关于不同环境污染物迁移到植物中以及它们被摄入胃后所发生的变化的第一项综合研究。
