Biological & Complex Matrices

At GreenWater Laboratories, we have developed multiple approaches to handling complicated matrices, such as animal tissues, plant material, sediment/soil samples and algal supplements.  We understand the importance of providing reliable data and continue to develop and improve upon our approaches to serve our client goals. 

GreenWater Laboratories uses the highest level of QAQC to verify that the data we provide clients is accurate. This includes using standard addition to validate method procedures and for quantitation, as well as continued calibration checks, lab fortified blanks and verifying blanks are free of contamination.

Algal Poisoning of Pets

The most sensitive individuals to algal toxin poisoning are those that ingest cyanobacteria when they are in the water. Many times, those individuals are dogs, since they are entering and exiting algal blooms at shorelines. It is a good idea to keep pets out of the water when cyanobacteria may be present. If your family pet is exhibiting any of the following symptoms after swimming, contact your veterinarian immediately.

  • Malaise/lethargy/loss of appetite
  • Vomiting and/or Diarrhea
  • Collapse/Inability to walk
  • Pale or Jaundice (yellow) gums
  • Seizures/Tremors
  • Difficulty Breathing
  • Hypersalivation


Samples to submit for testing should include the source water, vomitous (or any retrievable stomach contents) and/or urine. If the animal is deceased, the kidney or liver can be submitted.

Wildlife Mortality Events

Cyanobacteria blooms have been attributed to mass mortality events of many different animals, including fish, birds and livestock.  If you suspect an event is tied to an algal bloom, the first collection should be of the water source so that identification of the cyanobacteria present can be made.   Toxin testing of the water/bloom material also helps to determine if toxin levels are sufficient to have caused animal intoxication.  Many times, an event has a complicated etiology, with more than one toxin and/or stressor present.  GreenWater Laboratories can help wildlife officials diagnose these events.

The following biological samples can be submitted for testing, in order of importance:

  • Water
  • Stomach Contents
  • Urine
  • Kidneys
  • Liver

Food Products -
Shellfish/Fish, Algal Supplements, Vegetables

GreenWater Laboratories frequently tests food products for algal toxins, including shellfish, fish filets, algal supplements, and vegetables that have been in contact with water with active algal blooms.  We conduct testing for the same algal toxins present in water, with the addition of extraction charges.
