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.

甘蓝亚种生长过程中土壤环境中荧蒽、菲和芘的迁移。

人们对荧蒽（FLN）、菲（Phe）和芘（Pyr）的关注与日俱增，这凸显了研究它们在农业生态系统中的动态变化的紧迫性。大白菜（Brassica rapa subsp.chinensis）是一种全球食用的蔬菜，在这种情况下具有特别重要的意义。本研究探讨了 FLN、Phe 和 Pyr 在大白菜生长过程中从土壤向大白菜亚种的迁移和转化。这些处理的种子萌发率各不相同，土壤+大白菜和土壤+FLN+大白菜处理的萌发率较高（77.8%），而土壤+混合+大白菜处理的萌发率最低（11.1%）。分析 30 天后 FLN、Phe 和 Pyr 在甘蓝亚种中的分布，发现其积累顺序为茎>根>叶。这项研究为调节 FLN、Phe 和 Pyr 在土壤-植物间的迁移和转化提供了实用信息，为农业环境中多环芳烃污染的迁移提供了有价值的见解。

期刊介绍： Environmental Toxicology and Pharmacology publishes the results of studies concerning toxic and pharmacological effects of (human and veterinary) drugs and of environmental contaminants in animals and man. Areas of special interest are: molecular mechanisms of toxicity, biotransformation and toxicokinetics (including toxicokinetic modelling), molecular, biochemical and physiological mechanisms explaining differences in sensitivity between species and individuals, the characterisation of pathophysiological models and mechanisms involved in the development of effects and the identification of biological markers that can be used to study exposure and effects in man and animals. In addition to full length papers, short communications, full-length reviews and mini-reviews, Environmental Toxicology and Pharmacology will publish in depth assessments of special problem areas. The latter publications may exceed the length of a full length paper three to fourfold. A basic requirement is that the assessments are made under the auspices of international groups of leading experts in the fields concerned. The information examined may either consist of data that were already published, or of new data that were obtained within the framework of collaborative research programmes. Provision is also made for the acceptance of minireviews on (classes of) compounds, toxicities or mechanisms, debating recent advances in rapidly developing fields that fall within the scope of the journal.
