This Enzyme-Linked Immuno Sorbent Assay is a method for quantitative measurement of dissolved microcystins in water.
Microcystins are toxins produced by cyanobacteria, also called blue-green algae, that can cause health problems to humans and domestic animals. Water blooms of these organisms often develop in nutrient-rich (eutrophic) waters.
The test is applicable on surface water and drinking water and has a limit of quantification below 1 µg/l.
World-wide, eutrophication is considered the most important water quality issue. Consequences of eutrophication are, amongst other things, blooms of blue-green algae, water clouding and the disappearance of submersed water plants.In particular, the nuisance that arises by cyanobacteria blooms is most serious, because toxins can be released when the bloom deteriorates.
Another aspect is the occurrence of oxygen depletion when a bloom dies.
In such cases the water is no longer suitable for recreation or drinking water production. The health-based standards for microcystins are: 1 µg/l for drinking water and 20 µg/l for recreational waters.
Therefore this microcystin ELISA test can be very useful. It complies to the ISO 15089 standard for environmental immune-assays and the method is accredited by BELAC.
