Abstract

Alternative chemicals to bisphenol A (BPA), such as bisphenol F (BPF), have been detected in aquatic environments worldwide and can potentially exert negative effects on aquatic organisms. To evaluate the toxic effects of the exposure of BPF on submerged macrophytes and biofilms, Ceratophyllum demersum L. (C. demersum) was exposed to different concentrations of BPF (1, 5, 10, and 20 mg L-1). In general, the growth of C. demersum was inhibited, and the chlorophyll content of C. demersum noticeably decreased at high concentrations of BPF (20 mg L-1). In addition, different concentrations of exposure to BPF induced a certain degree of oxidative stress, as evidenced by increased the activities of superoxide dismutase, catalase, and peroxidase, as well as increased malondialdehyde concentrations. Furthermore, the scanning electron microscopy results and high-throughput sequencing analysis showed the diversity and structure of the microbial community were altered on the leaf biofilms in the presence of BPF. In addition, the leaf cells of C. demersum showed some damage and variation of organelles and membranes when examined by transmission electron microscopy. The current study is the first to assess the effects of BPF on the physiological and biochemical of C. demersum, these results suggest the understanding of how submerged macrophyte and leaf biofilms respond to environmental stress induced by BPF.

双酚 F 对沉水大型藻类 Ceratophyllum demersum L 的生长、抗氧化反应、超微结构和微生物特性的毒理学影响
双酚 A(BPA)的替代化学品,如双酚 F(BPF),已在世界各地的水生环境中检测到,并可能对水生生物产生负面影响。为了评估暴露于 BPF 对水下大型植物和生物膜的毒性影响,Ceratophyllum demersum L. (C. demersum)被暴露于不同浓度的 BPF(1、5、10 和 20 mg L-1)。一般来说,高浓度的 BPF(20 毫克/升)会抑制 C. demersum 的生长,并明显降低其叶绿素含量。此外,暴露于不同浓度的 BPF 会诱发一定程度的氧化应激,表现为超氧化物歧化酶、过氧化氢酶和过氧化物酶活性的增加,以及丙二醛浓度的增加。此外,扫描电子显微镜结果和高通量测序分析表明,在 BPF 的存在下,叶片生物膜上微生物群落的多样性和结构发生了改变。此外,透射电子显微镜观察 C. demersum 的叶片细胞时发现,细胞器和细胞膜出现了一些损伤和变化。本研究首次评估了 BPF 对 C. demersum 生理生化的影响,这些结果有助于了解沉水大型藻类和叶片生物膜如何应对 BPF 诱导的环境压力。

期刊介绍: The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
