• To prepare antiviral filters for masks

Green tide in Europe are becoming more frequent

• Green tide in Europe are becoming more frequent

• More than 70 000 tons of green algae collected in Brittany in 2015

• Species: Ulva armoricana and U. retundata (nitrophile)

• Causes: Nitrates and phosphorus from artificial fertilizers.

• Consequences:

• - Economic: tourism, cost of the algae collection,

• - Environmental and sanitary: decomposition with H2S emanations
