Residents in Luoyang, China were surely surprised when the nearby Jian River recently changed a brilliant blood-red. The shocking color change apparently has nothing to do with the end of days, but with chemical dyes dumped in the river from so-called “illegal workshops.” As startling as the appearance of the river, more troubling are reports that it is still unknown if the dye poses a health risk or even how long the Jian will remain red. I certainly wouldn’t go near it, that’s for sure.
