  • About the Program
    CDC's Environmental Hazards and Health Effects Program (EHHE) promotes health and quality of life by preventing or controlling diseases or deaths that result from interactions between people and their environment ...more
  • Focus Areas
    • Air Pollution and Respiratory Health
      The Air Pollution and Respiratory Health Program (APRHB) leads CDC’s fight against environmental-related respiratory illnesses, including asthma, and studies indoor and outdoor air pollution ...more
    • Asthma
      Asthma is a serious environmental health threat, but it can be controlled by taking medication and by avoiding contact with environmental "triggers" such as dust mites, furry pets, mold, tobacco smoke, and certain chemicals. CDC works with state grantees to reduce the number of deaths, hospitalizations, emergency department visits, school days or workdays missed, and limitations on activity due to asthma ...more
    • Cancer Clusters
      A cancer cluster is a greater-than-expected number of cancer cases that occurs within a group of people in a geographic area over a period of time. CDC provides cancer cluster information and resources, responds to inquiries about cancer clusters, and works with state health departments to address public health concerns about potential cancer clusters ...more
    • Carbon Monoxide
      CDC works with national and state data sources to monitor, evaluate, and present information on carbon-monoxide-related illness and death in the U.S ...more
    • Concentrated Animal Feeding Operations
      Concentrated animal feeding operations (CAFOs) are agricultural facilities that house and feed a large number of animals in a confined area for 45 days or more during any 12-month period. CDC is working with states to define routes of exposure and potential human health effects from exposures to wastes and residues from confined animal feeding operations ...more
    • Environmental Public Health Indicators
      Environmental public health indicators (EPHIs) can be used to assess our health status or risk as it relates to our environment. They may be used to assess baseline status and trends, track program goals and objectives, and build core surveillance capacity in state and local agencies ...more
    • Environmental Public Health Tracking
      Environmental Public Health Tracking (EPHT) is the ongoing collection, integration, analysis, interpretation, and dissemination of data on environmental hazards, exposures to those hazards, and health effects that may be related to the exposures. The goal of tracking is to provide information that can be used to plan, apply, and evaluate actions to prevent and control environmentally related diseases ...more
    • FEMA Trailer Study
      The Centers for Disease Control and Prevention (CDC) is responding to concerns about air quality in FEMA temporary housing units ...more
    • Harmful Algal Blooms
      CDC is supporting surveillance programs, epidemiologic studies, and laboratory research to further define the relation between exposure to organisms involved in harmful algal blooms, such as Pfiesteria piscicida, and human illness ...more
    • Health Studies
      CDC investigates the human health effects of exposure to environmental hazards ranging from chemical pollutants to natural, technologic, or terrorist disasters. The results are used to develop, implement, and evaluate strategies for preventing or reducing harmful exposures ...more
    • Mold
      CDC provides information on mold and health, an inventory of state indoor air quality programs, advice on assessment, cleanup efforts, and prevention of mold growth, and links to resources ...more
    • Radiation Studies
      CDC identifies potentially harmful environmental exposures to ionizing radiation and associated toxicants, conducts energy-related health research, and responds to protect the public’s health in the event of an emergency involving radiation or radioactive materials ...more
    • US-Mexico Border Environmental Health
      CDC identifies environmental health issues, trains and develops human resources, and conducts environmental epidemiologic research in the U.S.-Mexico border area ...more
    • Water-Related Environmental Public Health
      CDC is working to identify, investigate, and track health hazards associated with water, measure exposure of people to these hazards, and prevent health effects from these hazards ...more
