A new study reveals that wildfire retardants used by the U.S. Forest Service between 2009 and 2021 have contributed to heavy metal pollution, releasing over 400 tons of toxic metals such as cadmium and chromium into the environment. These metals can have severe implications for health and ecosystems. The findings have ignited discussions among environmental groups and officials about the potential risks associated with these chemicals. While firefighting remains critical, the study highlights the need for transparently assessing the environmental impact and safety of retardants used during wildfire management efforts.
Wildfire retardant application in the U.S. has released over 400 tons of toxic metals between 2009 and 2021, raising environmental and health concerns.
The heavy metals report from USC has prompted discussions about the use of these retardants, indicating potential shifts in firefighting strategies.
Composed of mostly water and fertilizers, wildfire retardant includes undisclosed ingredients that could cause long-term ecological damage due to heavy metal accumulation.
The significant increase in the application of fire retardants correlates with the dramatic rise in wildfire incidents in the western U.S. over the last four decades.
