Blue-Green Algae Safety Checklist
There are many factors known to trigger algal blooms
light, temperature, nutrients, pH, salinity, grazing
name a few. However the exact combination of factors that
cause the blooms are not yet well understood. Algal blooms
may deplete oxygen concentrations in water which leads
to smothering fish, other animals and plant life, Floating
algal masses can suffocate rice crops and prevent young
plants from emerging, They block pipes,
irrigation channels and pumps.
Cyanobacteria (Blue Green Algae)
Cyanobacteria are a type of bacteria that obtain their energy by photosynthesis and can therefore manufacture their own food. They are the oldest known fossils, more than 3.5 billion years old. Indeed they are one of the largest and most important groups of bacteria on earth.
in almost all environments.
In aquatic environments, under certain conditions, cyanobacteria
may form dense blooms known as blue green algae. The blooms
of blue green algae may produce toxins that may be poisonous to
humans, animals and render seafood toxic. Even if cyanobacteria
do not produce toxins, blooms can cause water to have an
taste and odour. However all blue green algae are contact
irritants which cause conditions ranging from minor irritation to
Some cyanobacteria have the ability to produce
gas and they store it in small bubbles within themselves. This
enables them to float to the surface forming a dense mass which
can reduce the aesthetic and recreational value of the water body.
This mass also traps litter and sediment and reduces the holding
capacity of a dam, pond, lake, or reservoir and causes a scum with
a very unpleasant smell.
