Abstract

The records of blooms and cyanotoxins in the Brazilian Legal Amazon are scarce and do not represent the reality observed in recent years when there was an increase in notifications and studies carried out in this region. In this article, we carefully analyzed 48 studies to identify the locations where the blooms occurred, the most frequent species, and the tests performed to detect cyanotoxins within the territory of the Brazilian Legal Amazon. The analyzed studies identified approximately 145 taxa of cyanobacteria, and the most frequent species belong to the genera and . The most frequently detected cyanotoxin was microcystin, and, in some locations, even with a low cell density, there was the production of toxins. In most cases, and were the major genera associated with blooms and toxin production. The state of Pará had the highest number of records of toxin-producing cyanobacteria, including records of seasonal events, while Acre had no records. This work contributes to our knowledge of the geographic distribution and occurrence of cyanobacteria and cyanotoxins in the Brazilian Amazon and proposes new strategies for improving the monitoring of cyanotoxins in the Amazon region.

摘要

巴西法定亚马逊地区有关水华和蓝藻毒素的记录稀缺，无法反映近年来该地区报告数量增加及相关研究开展后所观察到的实际情况。在本文中，我们仔细分析了48项研究，以确定巴西法定亚马逊地区境内水华发生的地点、最常见的物种，以及检测蓝藻毒素所进行的测试。分析的研究确定了约145种蓝藻分类群，最常见的物种属于 属和 属。最常检测到的蓝藻毒素是微囊藻毒素，在一些地点，即使细胞密度较低，也会产生毒素。在大多数情况下， 属和 属是与水华和毒素产生相关的主要属。帕拉州产毒蓝藻的记录数量最多，包括季节性事件的记录，而阿克里州则没有记录。这项工作有助于我们了解巴西亚马逊地区蓝藻和蓝藻毒素的地理分布及发生情况，并为改进亚马逊地区蓝藻毒素监测提出新策略。
