  "description": "This dataset is comprised of cyanotoxin concentrations from whole water cyanotoxin samples collected at water quality stations in the Sacramento-San Joaquin Delta, beginning in 2020. Cyanotoxin congeners were measured from whole water cyanotoxin samples within the cyanotoxin classes: microcystins, anatoxins, cylindrospermopsins, saxitoxins, anabaenopeptins, and nodularin. Concentrations were measured using liquid chromatography tandem mass spectrometry (LC-MS/MS) and enzyme linked immunosorbent assay (ELISA).",
