Cyanotoxins in the California Sacramento-San Joaquin Delta: Fixed Station Solid Phase Adsorption Toxin Tracking (SPATT) samplers
This dataset is comprised of cyanotoxin concentrations in extracts from solid phase adsorption toxin tracking (SPATT) samplers deployed at fixed sampling stations in the Sacramento-San Joaquin Delta, beginning in 2020. SPATT samplers are a form of passive sampler constructed of adsorbent resin beads that concentrate cyanotoxins over time. Cyanotoxin congeners were measured from SPATT extracts within the cyanotoxin classes: microcystins, anatoxins, cylindrospermopsins, saxitoxins, anabaenopeptins, and nodularin. Concentrations were measured using liquid chromatography tandem mass spectrometry (LC-MS/MS), with some samples also measured with enzyme linked immunosorbent assay (ELISA).
