The National Toxicology Program (NTP) concludes that there is ***sufficient**** *evidence for adverse health effects in children and adults at blood Pb levels below 10μg/dL and below 5μg/dL as well.  The table below provides a summary of effect by life stage at which the effect is identified.   ![National Toxicology Program logo](https://www.shawnmccadden.com/hs-fs/file-15778396-jpg/images/national-toxicology-program-logo-wr.jpg)   ![HEALTH EFFECTS OF LOW-LEVEL LEAD](https://www.shawnmccadden.com/hs-fs/file-15763020-jpg/images/health_effects_of_low_levels_lead-wr.jpg?width=648&height=331&name=health_effects_of_low_levels_lead-wr.jpg) **Note: This information was found in a document published by NTP titled:** [Draft NTP Monograph on Health Effects of Low-Level Lead](http://ntp.niehs.nih.gov/NTP/ohat/Lead/DraftNTPMonographonHealthEffectsofLowLevelLead.pdf), dated 10/14/11   Topics: [Opt Out Related](https://www.shawnmccadden.com/rrpedia/topic/opt-out-related), [Statistics](https://www.shawnmccadden.com/rrpedia/topic/statistics), [Health Effects of Lead](https://www.shawnmccadden.com/rrpedia/topic/health-effects-of-lead), [Non-RRP Lead Topics](https://www.shawnmccadden.com/rrpedia/topic/non-rrp-lead-topics), [Personal Protection](https://www.shawnmccadden.com/rrpedia/topic/personal-protection) [![cs-ye-234x16](https://www.shawnmccadden.com/hs-fs/hub/81069/file-1553381212.gif)](http://www.copyscape.com/duplicate-content/) ### Subscribe to RRPedia by Email and get notified about new postings as soon as they happen! ### Are You Documenting Yor Crew's Compliance With The RRP Rule?  [![download free RRP checklist](https://no-cache.hubspot.com/cta/default/81069/dd6aace9-6cb0-4ad2-a55a-09846d7f5b5e.png)](https://cta-redirect.hubspot.com/cta/redirect/81069/dd6aace9-6cb0-4ad2-a55a-09846d7f5b5e) ### Still Using a Yellow Pad for Your Estimating?
