The National Biomonitoring Network (NBN) is a collaboration of federal, regional, state and local laboratories that conduct biomonitoring for use in public health practice and in response to environmental emergencies.

NBN MapThe goals of the NBN are to advance the science of biomonitoring, encourage its use in addressing environmental health questions and ensure quality practices, which will help produce comparable biomonitoring data. The NBN will do this by:

  • Defining best practices for study design
  • Developing approaches for stakeholder engagement
  • Harmonizing laboratory methods
  • Guiding risk communication and results reporting
  • Exploring a central repository for biomonitoring data


APHL formed the NBN by building upon two successive five-year biomonitoring plans and leveraging the infrastructure and analytical capabilities developed through the LRN-C and state biomonitoring cooperative agreements.


A Network Steering Committee (NSC) of experts in epidemiology, toxicology, analytical chemistry, occupational health, data analysis, risk communication and public health policy was established to guide the development and implementation of the NBN.

Current Projects

The NSC forms topical workgroups, as needed, to develop NBN related guidance, procedures and policies. Technical guidance related to study design and method harmonization are in progress, as is the development of a NBN membership process. The NSC anticipates convening workgroups related to data management, communications and more in the near future.
