摘要

全球沿海和内陆水域蓝藻水华(CyBs)发生的频率、规模和持续时间不断增加,引起了人们的严重关注,因为蓝藻毒素会渗入水库,对水生生态系统和人类健康造成负面影响。这一令人担忧的趋势因水生生态系统中营养物质释放量的增加、大气中二氧化碳(CO2)浓度的上升以及与气候变化相关的温度升高而进一步加剧,这些因素都大大加剧了蓝藻的问题。这种综合策略成功地减少了二次污染物对水生生态系统的影响。此外,通过控制营养物浓度和浮游植物群落的组成,这种量身定制的方法为解决 CyBs 对水质的负面影响提供了一种途径。摘要近年来,人们对富营养化水生生态系统中的蓝藻演替进行了广泛的研究,以探究影响藻华形成的因素,并建立控制和预防水体中 CyBs 的缓解策略。尽管取得了这些进展,但要全面了解水文格局、生物多样性和水生环境中化学成分之间复杂的相互作用,仍面临巨大挑战。为了确保水资源的长期可持续性,必须实施一项全面的管理计划,从各个方面预防 CyB。本综述将评估预防、控制和缓解 CyBs 战略的最新进展,并评价这些战略在该领域的有效性和重要性,同时还将为 CyB 控制方面的未来研究提供建议,以进一步加强我们对 CyBs 的了解和管理。

Cyanobacterial Blooms in Environmental Water: Causes and Solutions

Cyanobacterial Blooms in Environmental Water: Causes and Solutions

Purpose of Review

The increasing frequency, magnitude, and duration of cyanobacterial blooms (CyBs) in coastal and inland waters globally are causing serious concern because of the infiltration of cyanotoxins into water reservoirs and their negative effects on aquatic ecosystems and human health. This worrying trend is further exacerbated by the elevated levels of nutrient release in aquatic ecosystems, rising atmospheric carbon dioxide (CO2) concentrations, and increasing temperature associated with climate change, which have significantly exacerbated the issue of CyBs.

Recent Findings

Recent advancements in targeting key cyanobacterial traits have resulted in the development and implementation of next-generation physical methods that combine biological and chemical methodologies to effectively control CyBs. This comprehensive strategy successfully reduces the impact of secondary pollutants on aquatic ecosystems. Furthermore, by controlling nutrient concentrations and the composition of phytoplankton communities, this tailored approach provides an avenue for addressing CyBs’ negative impacts on water quality.

Summary

Extensive researches were conducted recently on cyanobacterial succession in eutrophic aquatic ecosystems to investigate the factors influencing bloom formation and to establish mitigation strategies for controlling and preventing CyBs in water bodies. Despite these advancements, there remain substantial challenges in comprehensively understanding the complex interplay between hydrological patterns, biological diversity, and chemical compositions within aquatic environments. To ensure the long-term sustainability of water resources, it is essential to implement a comprehensive management plan that addresses all aspects of CyB prevention. The review will assess recent advancements in strategies for preventing, controlling, and mitigating CyBs and evaluate their effectiveness and importance in the field, while also providing recommendations for future research in CyB control to further enhance our understanding and management of CyBs.
