Brazilian authorities say they are investigating river contamination levels after a truck accident caused a chemical dye spill in São Paulo.
The leak occurred after a vehicle carrying containers of a blue dye solution collided with a pole, causing the product to spill into a manhole connected to the Jundiai River.
City officials say they are acting to rescue and save the lives of the affected animals.
The dye is an organic chemical based on acetic acid – used in Styrofoam boxes and egg cartons.
