CHINA’S Yangtze river has turned scarlet. And nobody knows why.
The renown river – known as “the golden waterway” – in south-western China suddenly turned blood-red at the weekend.
The polluted water is mostly concentrated around the industrial city of Chongquing, but has been reported in several other locations.
Reports suggest industrial pollution in silt churned up by recent floods is being blamed by Chinese officials for the discolouration.
The Yangtze is regarded as being too fast-flowing and large to generate a “red tide” effect associated with bacteria infestations of low-oxygen ponds.
An industrial dye used in firework wrappers was blamed when another Chinese river, the Jian, turned red last year.
