Benthic cyanos are natural, do not result from water pollution and have been on Earth for 4 billion years.

They form a slippery film (a biofilm) on the surface of submerged minerals or plants.

As they detach, these biofilms form flocs that accumulate in areas of stagnant or slow-moving water, and can be black, green, dark brown or gray …

They are generally found in areas of current (0.3 m/s), shallow
(< 70 cm). They can be found all year round, but warm weather favors their development.

There is no dilution of toxin in water (to dangerous levels).

You don’t get intoxicated by drinking the cup, but by ingesting the biofilms.

• Watch out for small children: don’t let them mouth pebbles or stones along the river.
• Watch out for your pets: don’t let them play with pebbles or sticks. If in doubt, take something to drink.
• Fishermen: do not eat small fish whole, quickly gut and head larger fish.
• In case of symptoms (tremors, fever, abdominal pain, muscle pain, nausea and vomiting in children / tremors, loss of balance, bulging eyes, nausea, drooling in dogs), react quickly and consult a doctor / veterinarian.

From July 1 to August 31, a specific monitoring protocol tracks the evolution of cyanobacteria to inform the public.

5 “bacteriological control” samples are organized from the end of June to August 31 at 13 bathing sites

No, water quality has nothing to do with the presence of cyanobacteria!
