Water quality and biochemical analysis associated with a canine death linked to neurotoxic cyanobacterial metaphyton in Lake Travis, Austin, Texas

The first confirmed dog death on Lake Travis (Texas) caused by the cyanotoxin, dihydroanatoxin-a, occurred on February 20, 2021. Data represent water quality samples collected from October 2015 through August 2021 on Lake Travis as part of the routine monitoring conducted by the Texas Clean Rivers Program. All water quality samples were collected following the Surface Water Quality Monitoring Procedures manual set forth by Texas Commission on Environmental Quality. Toxin data was analyzed using either LC-MS/MS or ELISA for the different cyanotoxin types and congeners. Datasets contain raw data pulls from a Microsoft SQL Server database and processed data useful for analysis. Third-party reports on toxin analysis, cyanobacterial presence via visual identification, and dog necropsy findings are also provided.

2021年2月20日，得克萨斯州特拉维斯湖（Lake Travis）发生首例经确认的由蓝藻毒素二氢鱼腥藻毒素-a（dihydroanatoxin-a）引发的犬只死亡事件。本数据集涵盖2015年10月至2021年8月期间在特拉维斯湖采集的水质样本，相关采样为得克萨斯州清洁河流计划（Texas Clean Rivers Program）开展的常规监测内容之一。所有水质样本均严格遵循得克萨斯州环境质量委员会（Texas Commission on Environmental Quality）发布的《地表水水质监测规程手册》进行采集。针对不同蓝藻毒素类型及其同系物，毒素检测数据分别采用液相色谱-串联质谱法（LC-MS/MS）与酶联免疫吸附试验（ELISA）完成分析。数据集包含从微软SQL Server（Microsoft SQL Server）数据库导出的原始数据，以及可用于后续分析的预处理数据。此外还附带第三方毒素分析报告、通过目视鉴定得到的蓝藻存在情况报告，以及犬只尸检结果文件。
