How Effective is Home Water Filtration in Microcystin Removal

What is Microcystin?

Microcystin is a toxin produced naturally in cyanobacteria, which are also known as blue-green algae. It is a type of cyanotoxin and can have several harmful effects on human health. Most Microcystins are hepatotoxins, meaning they affect the liver. However, not all blue-green algae species produce microcystin — and microcystin is only one type of toxin that cyanobacteria can produce. Cyanobacteria are commonly found in surface waters when conditions are favorable for their growth. They are stable in sunlight and thrive in sunny conditions.  One common type of cyanobacteria that releases microcystin is known as Microcystis. Microcystis blooms are typically green, thick, and sometimes granular, with a consistency resembling that of paint. They tend to accumulate along the shorelines of lakes and ponds. 

Conditions favorable to cyanobacterial growth include warm temperatures and an abundance of nutrients — especially nitrogen and phosphorus — in the water. Temperatures ranging from five to 30 degrees Celsius (41F – 86F) can foster cyanobacterial growth, but temperatures ranging from 20 to 25 degrees Celsius (68F – 77F) are ideal, as are higher pH levels, generally between 6 and 9.  Since UAE experiences high temperature, it can  be considered as one of the regions susceptible to cyanobacterial (particularly Microcystin) growth. The following are some of the prominent health impacts indicating presence of Microcystin in source water:

  • Abdominal pain
  • Blistering of the mouth
  • Diarrhea
  • Dry cough and sore throat
  • Eye pain and blurred vision
  • Headaches
  • Kidney damage
  • Liver inflammation
  • Liver hemorrhage
  • Nausea and vomiting
  • Pneumonia
