National Center for Environmental Health

CDC’s National Center for Environmental Health (NCEH) plans, directs, and coordinates a program to protect the American people from environmental hazards. We promote a healthy environment and prevent premature death,  avoidable illness and disability caused by non-infectious, non-occupational environmental and related factors. We are especially committed to safeguarding the health of vulnerable populations – such as children, the elderly, and people with disabilities – from certain environmental hazards.
