Detection of cylindrospermopsin toxin markers in cyanobacterial algal blooms using analytical pyrolysis (Py-GC/MS) and thermally-assisted hydrolysis and methylation (TCh-GC/MS).

Highlights: [•] Pyrolytic techniques are a potential tool for CYN analysis from cyanobacterial blooms. [•] Specific molecular fragments can be used as CYN markers in environmental samples. [•] A diagnostic ion (m/z 194) could be used for CYN detection by conventional Py-GC/MS. [•] The characteristic peak (m/z 336) could have diagnostic value to detect CYN by TCh-GC/MS.
