    • Cyanotoxin Concentrations in Extracts from Solid Phase Adsorption Toxin Tracking (SPATT) and Diffusive Gradients in Thin-Films (DGT) Samplers in Owasco Lake, Seneca Lake, and Skaneateles Lake, Finger Lakes Region, New York, 2019

    Metadata Updated: January 7, 2026

    This data release contains dissolved cyanotoxin concentrations for microcystins (MC), cylindrospermopsins (CYL), anatoxins (ATX), and saxitoxins (STX) assessed using enzyme-linked immunosorbent assays (ELISA) and liquid chromatography-mass spectrometry or tandem mass spectrometry (LC-MS and LC-MS/MS, respectively) in extracts from SPATT (n=95) and DGT samplers (n=10) deployed on three Finger Lakes (Owasco, Seneca, and Skaneateles) between June and November 2019. Relative percent contributions of microcystin congeners are also provided for samples analyzed by LC-MS and LC-MS/MS. Solid phase adsorption toxin tracking (SPATT) and diffusive gradients in thin-films (DGT) are types of passive environmental samplers containing porous synthetic resin beads that adsorb and concentrate cyanotoxins over time. SPATT and DGT samplers are relatively inexpensive to construct and have been widely demonstrated to adsorb a range of cyanotoxins in different environments. These samplers can be deployed in water bodies for time periods ranging from hours to weeks and, upon extraction and analysis, provide a semi-quantitative, relative dissolved cyanotoxin concentration that is calculated based on the deployment length.
