Algal Toxins


Algal toxins are a group of toxic compounds produced by a range of photosynthetic freshwater and marine plankton. These toxins have the ability to cause sickness in animals and humans and in severe cases lead to death. OGRL has the ability to evaluate and conduct occurrence, fate, transport, effects, and treatability studies methods.


  • Sample collection requirements: 1-8 oz (250mL) or 1-16 oz (500mL) HDPE with polypropylene closure bottles per sample.
    • When submitting samples for total analysis (IMNT, IMYT, and IMXT) only fill bottles half-way to ensure that they do not break when frozen.
  • Instrumentation: ELISA or Liquid Chromatography/Tandem Mass Spectrometry
  • ELISA results uploaded to QWDX upon request.
