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 are primary producers present in many water bodies, certain types of which may produce potent toxins (known as cyanotoxins). They are known to impact human and animal health when exposed through recreational activities, consumption, and inhalation. In an effort to understand the presence of toxin-producing cyanobacteria in California water bodies, cyanobacteria samples were collected from 19 California water bodies. These data document the liquid chromatography triple quadrupole mass spectrometry (LC/MS/MS) results for 21 cyanotoxins and algal toxins in 41 cyanobacteria samples collected from California water bodies in 2015-2016.
