"Stunning Transformation: Western Japan's Serene River Transforms into Vibrant Lime Green"
The Tatsuta River in western Japan, known as a picturesque destination, suddenly turned bright lime green, prompting concern and an investigation. The cause was determined to be sodium fluorescein, a coloring agent used in bath salts, which had been dumped into the river. There were no reported health effects, and officials lifted their warning against agricultural use of the water. This incident follows a recent case in Okinawa where water turned blood red due to a propylene glycol leak from a local company's cooling system.
