The phosphorescent green color that stained part of the waters of Venice's Grand Canal on Sunday was due to the presence of fluorescein, a non-toxic substance generally used to test wastewater networks, local authorities announced this Monday (29).
The analysis of the water samples revealed “the presence of fluorescein”, declared, in a statement, the Regional Agency for Prevention and Protection of the Environment of Veneto (Arpav), the region where Venice is located.
The results “did not indicate the presence of toxic elements in the samples analyzed”, added the agency, without informing the origin of the presence of this substance in the Grand Canal.
Residents alerted authorities about the change in color of the water.
Local newspaper La Nuova Venezia reported that police had launched an investigation to find out whether the phenomenon was the result of a protest by environmentalists.
This is not the first time that the waters of the Grand Canal have appeared green.
In 1968, Argentine artist Nicolás García Uriburu dyed the waters of the canal during the 34th Venice Biennale to raise awareness about ecology.
