You’ve no doubt heard about the threat that heavy algae growth can pose for Australia’s waterways. But what many may not realise is that it’s not always simply the species of algae that can cause such damage, but the algal toxins secreted that threaten the health of Australia’s wildlife and leisure seekers.
Certain species of cyanobacteria, or blue-green algae, can produce toxins that are extremely harmful to humans and animals.
Globally, blue-green algae blooms have been implicated in fish kills and human and livestock deaths, rendering waters unsafe for all types of uses including, but not limited to, drinking, agriculture, irrigation and recreational enterprises.
Symbio Laboratories analyses algal toxins in water and can provide guidance on the most suitable test to conduct when the toxin producing species is identified via our test Algae ID and enumeration test series.
For reporting of total algae, blue-green algae or toxic species only algae, Symbio Laboratories customers can use the following test series:
Test series M60.1
Test series M60.2
Toxic Species only
Test series M60.3
The table below is a summary of some of the currently known freshwater toxigenic species based on research conducted in Australia, and the test required for toxin detection with Symbio Laboratories.
1ENV139 suite includes Anatoxin-a, Cylindrospermopsin, Deoxycylindrospermopsin, Microcystin-RR, Microcystin-YR, Microcystin-LR and Nodularin.
2ENV147 suite for Saxitoxins includes C1&C2 GTX-1&4, dcGTX-2&3, GTX-2&3, Saxitoxin and Neosaxitoxin.
What to do if you suspect an Algal Bloom
Collect a sample using a Symbio prepared opaque PET bottle and add Lugols preservative after sampling. For reporting of algal toxins, a second sample must be collected and submitted in a 40mL unpreserved amber glass vial. Contact our Customer Service team on 1300 703 166 for information on sample collection bottles, and see our Bottle Guidefor our complete range.
For Algal Toxin reporting, using the table above, enter the test(s) you require into an ARF i.e. for Cylindrospermopsin reporting enter ENV139.
What to do if you suspect algal toxins and require rapid results
Collect a sample in 40mL unpreserved amber glass vial. Contact our Customer Service team on 1300 703 166 for information on sample collection bottles, and see our Bottle Guide for our complete range.
Using the table above, determine which toxin test you require and enter into ARF i.e. for Cylindrospermopsin reporting enter ENV139.
If you have not submitted samples with Symbio Laboratories in the past, or submit infrequently, select both toxin tests (ENV139 AND ENV147).
Clients with historical data may be able to determine which toxic species tend to be in their samples and can choose either one or both.
