Abstract

Antibiotics and metal ions are frequently detected in aquatic environments, where they can form complex pollutants through mechanisms such as complexation, adsorption, co-precipitation, and biological interactions. These interactions significantly affect the physicochemical properties, transport dynamics, and ecotoxicity of the pollutants. Because of their persistence, potential for bioaccumulation, and complex interactions, these pollutants pose substantial challenges to water treatment systems and may present risks to human health and ecological balance. This review synthesizes research on the sources (1999-2024), status, and formation mechanisms of these complex pollutants. Initially, it outlines how complex pollutants originate from sources including pharmaceutical residues, agricultural runoff, and industrial discharges, which often coexist and interact to form these pollutants. The review then delves into the interaction mechanisms between antibiotics and metal ions, highlighting the factors that influence these interactions. Complexes (coordination polymers) formed by antibiotics and metal ions consist of infinite structures where metal ions and organic ligands act as the fundamental building blocks, connected through coordination bonds and other weak chemical interactions. Additionally, the review provides a comprehensive overview of various removal techniques, discussing their effectiveness and the technical challenges associated with treating these complex pollutants. The effects of antibiotics and metal ions on the migration and transformation mechanisms of the pollutants are also examined. Moreover, the biotoxicity associated with these composite pollutants is discussed, offering insights that could guide future strategies for effective degradation and control. PRACTITIONER POINTS: Combined contaminants of antibiotics and metal ions widely detected in water Combined contaminants change the physicochemical properties of a single substance. The transport transformation mechanisms of complex contaminants were summarized. The effect of combined contaminants on the removal of antibiotics and metal ions were evaluated.

水生系统中抗生素和金属离子复合污染的环境命运和生态毒理学行为。
抗生素和金属离子在水生环境中经常被检测到,它们可以通过络合、吸附、共沉淀和生物相互作用等机制形成复杂的污染物。这些相互作用显著影响污染物的理化性质、运移动力学和生态毒性。由于其持久性、潜在的生物积累和复杂的相互作用,这些污染物对水处理系统构成了重大挑战,并可能对人类健康和生态平衡构成威胁。本文综述了这些复杂污染物的来源(1999-2024)、现状及形成机制等方面的研究进展。首先,它概述了复杂的污染物如何来自包括药物残留物,农业径流和工业排放在内的来源,它们经常共存并相互作用形成这些污染物。该综述随后深入探讨了抗生素与金属离子之间的相互作用机制,强调了影响这些相互作用的因素。抗生素和金属离子形成的配合物(配位聚合物)由无限结构组成,其中金属离子和有机配体作为基本构件,通过配位键和其他弱化学相互作用连接在一起。此外,该综述还提供了各种去除技术的全面概述,讨论了它们的有效性和与处理这些复杂污染物相关的技术挑战。探讨了抗生素和金属离子对污染物迁移转化机制的影响。此外,还讨论了与这些复合污染物相关的生物毒性,提供了可以指导未来有效降解和控制策略的见解。执业要点:抗生素与水中广泛存在的金属离子复合污染物复合污染物改变单一物质的理化性质。综述了复杂污染物的输运转化机理。评价了复合污染物对抗生素和金属离子的去除效果。

期刊介绍: Published since 1928, Water Environment Research (WER) is an international multidisciplinary water resource management journal for the dissemination of fundamental and applied research in all scientific and technical areas related to water quality and resource recovery. WER''s goal is to foster communication and interdisciplinary research between water sciences and related fields such as environmental toxicology, agriculture, public and occupational health, microbiology, and ecology. In addition to original research articles, short communications, case studies, reviews, and perspectives are encouraged.
