Artificial sweeteners (ASs) have become an increasingly significant concern as an emerging contaminant. The widespread utilization has given rise to environmental consequences that are progressively harder to disregard. ASs infiltrate both aquatic and terrestrial ecosystems through the discharge of wastewater effluents and the application of manure and biosolids. These compounds can be absorbed and accumulated by plants from soil, water and the atmosphere, posing potential risks to ecological systems and human health. However, limited data available on plant absorption, translocation, and metabolism of ASs hinders a comprehensive understanding of their impact on ecosystem. This study aims to comprehensively summarize the global distribution of ASs, along with elucidating patterns of their uptake and accumulation within plants. Furthermore, it seeks to elucidate the pivotal factors governing ASs absorption and translocation, encompassing hydrophilicity, ionic nature, plant physiology, and environmental conditions. Notably, there remains a significant knowledge gap in understanding the biodegradation of ASs within plants, with their specific degradation pathways and mechanisms largely unexplored, thereby necessitating further investigation. Additionally, this review provides valuable insights into the ecotoxicological effects of ASs on plants. Finally, it identifies research gaps and outlines potential avenues for future research, offering a forward-looking perspective on this critical issue.

人造甜味剂在植物中的积累、易位和转化：批判性综述


人造甜味剂 （AS） 作为一种新兴污染物，已成为一个越来越重要的问题。广泛使用已经产生了越来越难以忽视的环境后果。AS 通过排放废水以及施用粪肥和生物固体渗透到水生和陆地生态系统中。这些化合物可被植物从土壤、水和大气中吸收和积累，对生态系统和人类健康构成潜在风险。然而，关于 AS 植物吸收、转运和代谢的有限数据阻碍了对其对生态系统影响的全面理解。本研究旨在全面总结 AS 的全球分布，并阐明它们在植物内吸收和积累的模式。此外，它试图阐明控制 AS 吸收和易位的关键因素，包括亲水性、离子性质、植物生理学和环境条件。值得注意的是，在了解植物体内 AS 的生物降解方面仍然存在很大的知识差距，其特定的降解途径和机制在很大程度上尚未探索，因此需要进一步研究。此外，这篇综述为 AS 对植物的生态毒理学影响提供了有价值的见解。最后，它确定了研究差距并概述了未来研究的潜在途径，为这一关键问题提供了前瞻性的观点。
