For what it&#x27;s worth, here is the actual chart with blood lead levels:<p><a href="https:&#x2F;&#x2F;www.epa.gov&#x2F;sites&#x2F;production&#x2F;files&#x2F;2015-10&#x2F;documents&#x2F;biomonitoring-lead-data.pdf" rel="nofollow">https:&#x2F;&#x2F;www.epa.gov&#x2F;sites&#x2F;production&#x2F;files&#x2F;2015-10&#x2F;documents...</a><p>IIRC the working draft of that report had a more detailed chart, but I don&#x27;t see it in the final version for whatever reason.
