Claim 1: “The findings from this CLEAN report suggest that the fires did release lead into the environment”

CORROBORATED

Multiple sources confirm that the fires released dangerous substances, specifically mentioning lead. One source explicitly links elevated lead levels in firefighters to the Palisades and Eaton fires, and another mentions the release of substances from batteries and paint during these specific fires.

Claim 4: “The CLEAN team also found that lead levels across a property can vary widely—on average, one sample from a property has about twice as much lead as another sample just a few feet away.”

SINGLE SOURCE

The provided evidence for this claim consists of irrelevant results (a 2021 film, CCleaner software, and a dictionary definition of 'clean'). No evidence regarding lead variance on properties was found.
