The Solution to Venice's Mysterious Green Canal Revealed.

The recent transformation of a section of Venice's Grand Canal to fluorescent green was caused by the non-toxic substance fluorescein, used for testing wastewater networks, according to the regional agency for environmental prevention and protection of Veneto. Police investigated whether it was a protest by climate change activists, but the substance was found to be harmless. The Grand Canal had previously turned green in 1968 as part of a stunt to promote ecological awareness.

Investigation Launched as Venice's Grand Canal Turns Fluorescent Green

A patch of water in Venice's Grand Canal turned fluorescent green, prompting an investigation involving police, the regional environmental agency, and other local bodies. The initial analysis suggested that there were no harmful substances in the water, and more tests will be conducted. The regional environmental agency suspects that fluorescein, a powdered dye that can be diluted in water, had been used, possibly by an environmental group. Venice is one of the world's most fragile cities, threatened by rising sea levels, and has instituted stringent rules for tourists to preserve the environment.
