确定影响蓝藻毒素微囊藻毒素 (MC) 出现和浓度的环境条件是预测该毒素会对饮用水源、娱乐水体和其他淡水生态系统产生不利影响的情况的关键步骤。尽管进行了广泛的研究，但对于全球范围内影响 MC 的因素仍鲜有共识。本研究的目的是利用世界各地湖泊和水库的观测数据来确定与 MC 浓度最密切相关的环境变量，同时解决大型聚合数据集经常涉及的大量缺失值。总共 124 项研究包含来自 22 个国家约 2040 个湖泊和水库的数据，用于构建全球数据集。变量包括
Determining the environmental conditions that influence the occurrence and concentration of the cyanobacterial toxin microcystin (MC) is a critical step for predicting cases in which the toxin will adversely affect drinking water sources, recreational waterbodies, and other freshwater ecosystems. Although widely studied, little consensus exists regarding the factors that influence MC on a global scale. The objective of this study was to identify the environmental variables most strongly associated with MC concentrations using observational data from lakes and reservoirs around the world while also addressing the substantial proportions of missing values that a large aggregated dataset often involves. A total of 124 studies containing data from an estimated 2040 lakes and reservoirs in 22 countries was used to construct a global dataset. Variables including
