Watch: Brazil’s Jundiaí River, ducks, and fish turn bright blue; What caused it and how officials are responding now

A chemical spill in Brazil’s São Paulo state has raised serious concerns about industrial safety and environmental protection. According to a BBC report cited by TOI, a truck carrying a blue dye crashed and leaked the chemical into the Jundiaí River, turning the water an unusual shade of blue.

The incident occurred when the truck lost control and hit a utility pole. The impact caused containers carrying an industrial dye solution to break open. The chemical then leaked into a manhole, which led directly to the Jundiaí River.

Emergency teams rushed to the scene soon after the water changed colour. Local authorities are now working to stop the spread of the dye and protect fish and other aquatic life in the river.



The spilled substance is a dye made with acetic acid, which is commonly used to make packaging materials like Styrofoam and egg cartons, the report said. Though it’s not considered highly toxic, releasing it into a natural water body can disturb the river’s ecosystem and harm animals that live in or near the water.


Environmental officials and rescue teams are monitoring the situation closely. Their main goal is to prevent further damage to plants and animals around the area. They are also checking the river for signs of harm to fish and other aquatic creatures.


Authorities say a full investigation is now underway to find out how the spill happened and whether proper safety rules were followed during the transport of the chemical.
