1.本文综述了淡水底栖有毒蓝藻增殖的生态学、毒素产生和影响。它记录了监测、管理和采样策略，并探讨了缓解方案。2.淡水底栖蓝细菌（附着在基质上生长的分类群）的毒性增殖发生在溪流、河流、湖泊以及温泉和融水池塘中，已有19个国家报告。最常报告的是含有类毒素和微囊藻毒素的草垫（分别为8个和10个国家）。3.研究探索促进有毒底栖蓝藻增殖的因素仅限于少数物种和生境。有一个重要的环境和生物因素，调节扩散与变量，如流量（河流），细沉积物沉积，营养物质，相关的微生物，放牧确定为关键驱动程序的层次。调节因素不同的殖民，扩张和扩散阶段。4.基于新组学的方法为底栖蓝藻的生理属性和相关微生物在促进其增殖中的作用提供了新的见解。5.细菌通常由有毒和无毒菌株组成，这些菌株的相对比例是影响每个垫子总毒素含量的关键因素。6.虽然这些事件在全球范围内越来越常见，但我们目前缺乏标准化的方法来检测，监测和管理这一新出现的健康问题。为了解决这些关键差距，需要全球合作，以促进知识的快速转移，并促进可应用于不同栖息地和物种的标准化技术的发展，并最终改善管理。
1. This review summarises knowledge on the ecology, toxin production, and impacts of toxic freshwater benthic cyanobacterial proliferations. It documents monitoring, management, and sampling strategies, and explores mitigation options. 2. Toxic proliferations of freshwater benthic cyanobacteria (taxa that grow attached to substrates) occur in streams, rivers, lakes, and thermal and meltwater ponds, and have been reported in 19 countries. Anatoxin- and microcystin-containing mats are most commonly reported (eight and 10 countries, respectively). 3. Studies exploring factors that promote toxic benthic cyanobacterial proliferations are limited to a few species and habitats. There is a hierarchy of importance in environmental and biological factors that regulate proliferations with variables such as flow (rivers), fine sediment deposition, nutrients, associated microbes, and grazing identified as key drivers. Regulating factors differ among colonisation, expansion, and dispersal phases. 4. New -omics-based approaches are providing novel insights into the physiological attributes of benthic cyanobacteria and the role of associated microorganisms in facilitating their proliferation. 5. Proliferations are commonly comprised of both toxic and non-toxic strains, and the relative proportion of these is the key factor contributing to the overall toxin content of each mat. 6. While these events are becoming more commonly reported globally, we currently lack standardised approaches to detect, monitor, and manage this emerging health issue. To solve these critical gaps, global collaborations are needed to facilitate the rapid transfer of knowledge and promote the development of standardised techniques that can be applied to diverse habitats and species, and ultimately lead to improved management.
