As multiple wildfires continue to torch Southern California, authorities are using planes to drop a large amount of bright pink fire retardant to curb the blaze.
Fire retardant is a mix of chemicals used to extinguish or slow down the spread of fires. There are different types of fire retardant but to tackle wildfires in the US, authorities most commonly use Phos-Chek — a brand of fire retardant — which mostly contains an ammonium phosphate-based slurry.
Typically, it is made of salts such as ammonium polyphosphate, which does not evaporate easily like water and stays for longer. Colour is usually added to the fire retardant to ensure that firefighters can see it against the landscape.
Environmental experts have said that spraying fire retardants using planes is ineffective, expensive and a growing source of pollution for rivers and streams.
These toxic metals include chromium and cadmium which can cause cancer, and kidney and liver diseases in humans. However, their adverse impact on the environment is of more concern, especially when retardants enter waterways.
