Highlights: Fluorescein is a non-toxic substance typically used for testing wastewater systems. The results, however, "did not demonstrate the presence of toxic elements in the samples analyzed," Arpav said. The change of color had been reported by residents, raising many questions. In 1968, the Argentine artist Nicolas Garcia Uriburu dyed his waters green with a fluorescent dye during the 34th Venice Biennale, as part of an ecological awareness campaign.. Activists from the last generation environmental movement repeated that they had nothing to do with what happened.

Japanese seaweed, pills thrown into the water by Norwegians or action of an environmental movement? Speculation about the origin of the color change of a section of the Grand Canal in Venice (Italy), which temporarily turned neon green on Sunday, was rife. The mystery was lifted on Monday. The analyses revealed "the presence of fluorescein in the samples taken," the Regional Agency for Prevention and Environmental Protection of Veneto (Arpav) said in a statement.

The results, however, "did not demonstrate the presence of toxic elements in the samples analyzed," she added, without specifying who or what is at the origin of the presence of this substance in the Grand Canal. Fluorescein is often used to trace poorly known networks or identify reversals between wastewater and stormwater systems.

Many questions

"No danger of pollution (...) but the risk of spread is worrying," the president of the Veneto region, Luca Zaia, said on Twitter on Monday. "Unfortunately, Venice has become the scene of actions far beyond its borders: adequate and strong responses are needed," he added.

The change of color had been reported by residents, raising many questions. According to the local daily La Nuova Venezia, the police have sought to know if climate change activists could be behind the phenomenon. Activists from the last generation environmental movement repeated that they had nothing to do with what happened, according to Corriere del Veneto.

This is not the first time the Grand Canal has turned green. In 1968, the Argentine artist Nicolas Garcia Uriburu dyed his waters green with a fluorescent dye during the 34th Venice Biennale, as part of an ecological awareness campaign.
