Summary

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 [...]

Purpose

Solid phase adsorption toxin tracking (SPATT) and diffusive gradients in thin-films (DGT) samplers were deployed to assess their utility as a tool in monitoring for the presence and relative concentrations of dissolved cyanotoxins in three low-nutrient Finger Lakes, where cyanotoxin concentrations in whole water are commonly below the detectable limit by enzyme-linked immunosorbent assays (ELISA). Extracts from passive samplers were preserved and analyzed according to ELISA kit manufacturer recommendations. A subset of extracts was chosen for additional analysis by liquid chromatography-mass spectrometry, tandem mass spectrometry (LC-MS and LC-MS/MS, respectively), or both. These data allow for comparisons of dissolved cyanotoxin concentrations from passive sampler extracts across multiple analytical methods and exploring impacts of ELISA preservatives on extracts analyzed by LC-MS and LC-MS/MS.
