Half of the children in the U.S. appear to have the toxic heavy metal lead in their blood, according to alarming new research.
After analyzing blood tests conducted on 1.14 million children younger than the age of six, scientists saw observable levels of the toxic metal in about half, according to a massive study published in the journal JAMA Pediatrics on Monday. And that number, compared to previous generations, is on the rise.
The scientists found that most of the affected kids — who had gotten a blood test for one reason or another between 2018 and 2020 — didn’t have enormous amounts of lead in their bloodstreams, and only two percent had a “high” level. But as the researchers note in their paper, there’s no such thing as a safe amount of lead to have in your system.
“The broad picture is: kids have lead in the U.S.,” Children’s Hospital at Montefiore lead poisoning prevention and treatment program director Morri Markowitz told Bloomberg. “For lead there’s no too low. We want zero.”
