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. The 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.
