Recent research sheds light on the environmental dangers of pink wildfire suppressants used by firefighting aircraft, revealing high levels of toxic heavy metals including cadmium, arsenic, and chromium. Aerial firefighting practices have escalated, with approximately 440 million gallons of these suppressants applied from 2009 to 2021. While the federal government and chemical manufacturers have withheld information on these chemicals under trade secret laws, this study provides crucial evidence linking the suppressants to severe environmental pollution. The presence of these metals raises concerns about their impact on human health as wildfires become more frequent and intense.
The new study reveals that substances used in pink wildfire suppressants contain toxic heavy metals like cadmium and arsenic, presenting significant environmental health hazards.
Despite claims of trade secrets protecting up to 20% of the aerial fire retardant contents, the study confirms alarming levels of metals far exceeding drinking water limits.
