Human Biomonitoring

Environmental health laboratories use biomonitoring to measure the amount of chemicals in a person’s body, which can help identify and track exposure trends and inform public health action. APHL produces resources and trainings that help laboratories and health agencies use biomonitoring data to understand and respond to environmental exposures.

About Human Biomonitoring

Biomonitoring measures the amount of specific chemicals in a person's body at a given time. When coupled with exposure information, laboratory data can offer insights into potential public health interventions and exposure reduction strategies. When samples are collected broadly and systematically, biomonitoring data can help identify and track trends, such as geographic regions with higher than typical exposure levels, or exposures to emerging contaminants. It can also identify when exposure is no longer a concern, perhaps as the result of a public health policy or intervention.

State Biomonitoring Programs

State biomonitoring programs investigate community concerns and/or systematically identify and track ongoing chemical exposure trends in their state populations. Through population-based surveillance or targeted investigations for groups with identified exposures, state biomonitoring programs work to improve community health and reduce chemical exposures.

Programs Funded by CDC State Biomonitoring Cooperative Agreement

State biomonitoring programs investigate community concerns and/or systematically identify and track ongoing chemical exposure trends in their state populations. Through population-based surveillance or targeted investigations for groups with identified exposures, state biomonitoring programs work to improve community health and reduce chemical exposures. State Biomonitoring Cooperative Agreement has funded states to expand targeted and population-based biomonitoring surveillance since 2009.

Our Work

Supporting Human Biomonitoring Programs

Technical Resources

APHL’s Biomonitoring Peer-to-peer Exchange Program matches biomonitoring laboratory scientists for in-person exchanges based on self-identified strengths and needs. These visits provide opportunities to share best practices, address challenges and build consistency across biomonitoring programs. APHL will fund travel for selected public health laboratory staff participants to visit peer laboratories for hands-on learning.

Applications for the 2026 cohort are closed.
