National Toxicology Program (NTP)
What it is
The National Toxicology Program is a US federal program, housed at the National Institute of Environmental Health Sciences, that has generated and shared toxicological information about potentially hazardous substances since 1978.
What it covers
Toxicology studies, health-effects assessments, and the Report on Carcinogens, which lists substances NTP has evaluated as known or reasonably anticipated human carcinogens.
How to verify
Reports, assessments, and study data are published on ntp.niehs.nih.gov. The individual report, not a news summary of it, is the citable object.
How SafeMama uses it
Cited by report name when a page discusses whether a specific chemical has been evaluated by a federal toxicology program, and what that evaluation found.
Limitations / conflicts
NTP assesses hazard: what a substance can do at the doses studied. Whether a given product exposes anyone to that dose is a separate question, and SafeMama keeps the two apart.
