Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanotoxins and algal toxins in estuary samples collected from California, USA, in 2016-17

Cyanobacteria known to produce cyanotoxins have been reported worldwide. As monitoring efforts have improved, they have been detected in not only freshwater, but also in estuary and marine waters. To assess the occurrence of cyanotoxins and algal toxins in California estuaries, the NOAA MERHAB funded project collected samples monthly from 11 Californian estuary locations, with 5 locations sampled in 2016 as event response. This data release includes liquid chromatography triple quadrupole mass spectrometry (LC/MS/MS) results for 21 cyanotoxins and algal toxins in estuary samples collected from California in 2016-2017.

Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanobacteria cultures from Lake Elsinore and Canyon Lake (CA, USA, 2016) for cyanotoxins and algal toxins

Cyanobacteria are common in inland water bodies. Many strains are known to produce potent toxins (cyanotoxins) which can impact human and animal health in sufficient concentrations. Lake Elsinore and Canyon Lake are two impaired lakes in California with frequent cyanobacteria blooms that are not monitored for toxin production. These data document the liquid chromatography triple quadrupole mass spectrometry (LC/MS/MS) results for 21 cyanotoxins and algal toxins in 13 cyanobacteria samples collected during bloom events from Lake Elsinore and Canyon Lake (CA, USA) in July, August, and September 2016.
