Cyanobacteria

Eurofins EnvironeX Laboratories now offers a wide range of services related to the problems of cyanobacteria (blue-green algae).

The increasing eutrophication of aquatic ecosystems encourages the development of cyanobacteria, also called blue-green algae. Under certain conditions they can rapidly proliferate and form blooms. Visible to the naked eye blooms are usually green or blue-green.

Some species of cyanobacteria produce toxins that can attack the liver, nervous system or irritate the skin. 

Cyanobacteria Analysis​ (blue-green algae)

The following analyses can be used to screen for cyanobacteria:

  • Monitoring and a full range of water analysis from potable water systems intended for human consumption in accordance with the Règlement sur la qualité de l’eau potable (RQEP)/(Regulation respecting the quality of drinking water) of Québec.

  • Total organic carbon (TOC) and dissolved organic carbon (DOC)
  • Biological oxygen demand (BOD5)
  • Chemical oxygen demand (COD)
  • Ammoniacal nitrogen (NH4+)
  • Total Kjeldahl nitrogen (TKN)
  • Total phosphorous
  • pH, conductivity, turbidity
  • Nitrites and nitrates
  • Dissolved oxygen
  • Several other parameters

  • Total coliform count and atypical bacteria
  • Fecal coliforms (E.Coli)
  • Fecal streptococci and enterococci
  • AAHB (aerobic and anaerobic heterotrophic bacteria)
