Eutrophication of lake and reservoir caused by cyanobacterial harmful algal blooms (cyanoHABs) become a global ecological problem because of massive destruction of ecosystems, which have attracted attentions widely. In addition to the production of cyanotoxins by certain bloom-forming species, there may also be direct or indirect interactions between cyanobacteria blooms and various pollutants in lakes or reservoirs. Based on bibliometrics, 19110 papers in Web of Science (WOS) and 2998 papers in the China National Knowledge Infrastructure (CNKI) on eutrophication and cyanobacterial blooms in lakes and reservoirs were analyzed, which showed that research on this topic has been ongoing for nearly 80 years with a gradual increase in its popularity. The research on the coupling process of cyanobacterial blooms with five typical pollutants, including microcystins (MCs), heavy metals, viruses, antibiotics and antibiotic resistance genes (ARGs), indicate that the coupling process between cyanobacteria blooms and certain pollutants is indeed generated through direct or indirect interactions by adsorption, changing the physical and chemical conditions of water environment, and changing the structure of microbial community. For instance, the production, toxicity would be likely enhanced by cyanobacteria blooms directly. And the microorganisms may play a significant role in the interaction between cyanobacteria blooms and ARGs. Generally, the risk of some typical pollutants would be likely enhanced or decreased directly or indirectly by these processes. It is recommended that further attention be paid to the interrelationships between the process of cyanobacterial bloom and typical pollutants' migration and transformation, to provide the scientific basis for the risk assessment and thus multi-objective synergistic control and management of nutrients and typical pollutants in eutrophic lakes or reservoirs.
由蓝藻有害藻华（cyanoHABs）导致的湖泊和水库富营养化，因其对生态系统的大规模破坏而成为一个全球性的生态问题，已引起广泛关注。除了某些形成藻华的物种会产生蓝藻毒素外，湖泊或水库中的蓝藻藻华与各种污染物之间还可能存在直接或间接的相互作用。基于文献计量学，对科学网（WOS）中19110篇以及中国知网（CNKI）中2998篇关于湖泊和水库富营养化及蓝藻藻华的论文进行了分析，结果表明对该主题的研究已持续近80年，且其受关注度逐渐增加。对蓝藻藻华与微囊藻毒素（MCs）、重金属、病毒、抗生素和抗生素抗性基因（ARGs）这五种典型污染物耦合过程的研究表明，蓝藻藻华与某些污染物之间的耦合过程确实是通过吸附、改变水环境的物理化学条件以及改变微生物群落结构等直接或间接相互作用产生的。例如，蓝藻藻华可能直接增强某些污染物的产生和毒性。并且微生物可能在蓝藻藻华与ARGs的相互作用中发挥重要作用。一般来说，这些过程可能直接或间接增强或降低某些典型污染物的风险。建议进一步关注蓝藻藻华过程与典型污染物迁移转化之间的相互关系，为风险评估提供科学依据，从而对富营养化湖泊或水库中的营养物质和典型污染物进行多目标协同控制与管理。
