Ammon News - Brazilian environmental authorities have launched an investigation into possible river contamination following a chemical spill caused by a truck accident in Sao Paulo, according to a BBC report.

The incident occurred when a truck transporting containers of a blue dye solution struck a utility pole. The collision ruptured the cargo, releasing the chemical into a manhole connected to the Jundiai River.

The spilled substance is an acetic acid-based organic dye commonly used in the production of Styrofoam packaging and egg cartons.

Local officials confirmed that emergency crews are responding to the incident and working to assess the environmental damage. Efforts are underway to rescue wildlife and minimise harm to aquatic ecosystems affected by the spill.
