Two professors at the University of Southern California discovered that Southern California may have avoided the worst danger of the hidden dangers of recent fires. This is lead exposure.
The previous prevalence of all lead, from paint to gasoline, poses a risk to the public, but is especially dangerous in the case of fires, as ash can carry heavy metals.
Luckily, when Seth John tested street dust and Samsilva sampled sandboxes at parks and kindergartens near the Etonfire site, their findings were first feared by Reid as Laist reported. It showed that it may not have been as widespread as it was.
It is true that street dust from the middle of the fiery Altadena showed lead levels that rise more than 20 times the limit of California’s EPA soil screening, but “there are almost all the materials collected from nearby neighborhoods. It wasn’t,” explains Laist.
“We were actually very relieved to discover that there was more lead in this dust, but that was not really concerning and not as toxic as we were afraid,” John said. He told Laist.
Lead is one heavy metal and others may still pose serious risks, but as Silva pointed out when discussing the findings of the sandbox, this study offers some comfort. Masu.
“As a scientist, this result is not very surprising, but as a parent I was deeply relieved,” he said.
