Abstract:
The escalating concern surrounding fluoranthene (FLN), phenanthrene (Phe), and pyrene (Pyr), underscores the urgency to investigate their dynamics in the context of agricultural ecosystems. Brassica rapa subsp. chinensis (Bok choy), a globally consumed vegetable, holds particular significance in this scenario. This study explores the migration and transformation of FLN, Phe, and Pyr from soil to Brassica rapa subsp. chinensis during its growth. The germination rates of seeds in these treatments varied, with soil+Bok choy and soil+FLN+Bok choy treatments showing higher rates (77.8 %), while soil+mix+Bok choy exhibited the lowest rate (11.1 %) after 3 days. Analyzing the distribution of FLN, Phe, and Pyr in Brassica rapa subsp. chinensis parts after 30 days revealed a sequence of accumulation in stem> root> leaf. This study provides information on practical implications for regulating the soil-plant migration and transformation of FLN, Phe, and Pyr, offering valuable insights for migration of PAHs pollution in agricultural settings.
摘要:
围绕荧蒽(FLN)不断升级的担忧,菲(Phe),和芘(Pyr),强调了在农业生态系统背景下调查其动态的紧迫性。油菜亚种。chinensis(Bokchoy),一种全球消费的蔬菜,在这种情况下具有特别重要的意义。本研究探讨了FLN的迁移和转化,Phe,和Pyr从土壤到芸苔属亚种。在它的生长过程中。这些处理中种子的发芽率各不相同,土壤+博克菜和土壤+FLN+博克菜处理显示出较高的比率(77.8%),而土壤+混合物+Bokchoy在3天后表现出最低的比率(11.1%)。分析FLN的分布,Phe,和Pyr在芸苔亚种中。30天后的中国部分显示茎>根>叶中的积累序列。这项研究提供了有关调节FLN的土壤-植物迁移和转化的实际意义的信息,Phe,还有Pyr,为农业环境中多环芳烃污染的迁移提供有价值的见解。
