Thick clouds of toxic foam cover Brazilian river
Thick clouds of toxic foam covered parts of a river in southeast Brazil, scattering downwards and worrying residents on Friday.
Drone images showed clouds of foam floating on the Tiete River in the town of Salto, the largest river in Sao Paulo with more than a thousand kilometers and crossing the state from east to west.
The stinky foamy layer comes from detergent wastes and chemical residues dumped into the river without treatment, according to local media.
