Advances in Causal Understanding

New molecular and bioinformatic approaches have advanced understanding of how molecular pathways are affected by exposure and the molecular networks involved in disease. However, these advances are often not yet deemed sufficient to establish causality for public health risk assessments; regulators still rely primarily on traditional apical endpoints, such as those endpoints observed in animal studies.


Radon is a colorless, odorless and tasteless gas that can cause lung cancer. Radon can accumulate to dangerous levels inside homes, schools, and other buildings. Radon can be tested for easily and if high levels are found, it can be removed at a relatively low cost

Radon is a naturally occuring gas and comes from the decay of Uranium in the ground. As Radon decays, it releases radioactive byproducts that are inhaled and can cause lung cancer. Radon is not only found in selected areas, but is found throughout the world. 


  • Is the leading cause of lung cancer among nonsmokers
  • Causes over 20,000 deaths per year in the U.S.
  • If you smoke and your home has a high radon level, your risk of lung cancer can increase

Environmental Health Saves Lives, Saves Money, and Protects Our Future

Environmental Health professionals ensure our air is safe by testing and mitigating radon in homes, schools and other buildings.


Built Environment and Climate Change

Built environment is the infrastructure of cities and towns that includes transportation, roadways, buildings, and land-use. Built environment design and development can help mitigate climate change, support adaptation, and improve environment and public health. The more resilient the built environment, the less impact from climate change.

Clean Air, Environment and Climate Change

Climate change affects the air we breathe and the environment around us. It is most noticeable with air pollution—soot, smog, and toxic pollutants and includes carbon pollution, as well as methane and hydrofluorocarbons.

World Environmental Health Day Toolkit

World Environmental Health Day on September 26, 2016 GraphicSocial Media Toolkit for Environmental Health Day

World EH Day, September 26, 2016, NEHA will be working with IFEH to engage with the community on the issues of second and third hand tobacco exposure.

This toolkit provides a set of sample social media messages, animations and graphics, key data points and newsletter blurbs that participants and supporters of this campaign can use in their personal and institutional accounts to distribute and amplify messages.

World Environmental Health Day Talking Points

  • September 26, 2016 is World Environmental Health Day to recognize the importance of protecting the air we breathe, the food we eat, and the water we drink and play in.
  • People in all communities deserve these basic essentials – safe water, clean air, safe food – to enjoy a healthy life and live up to their full potential.
  • Communities benefit when qualified, trained, and competent environmental health professionals work with health care providers, officials, local leaders, and businesses to educate, monitor, and enforce standards for these critical air, food, and water necessities.
  • EH professionals work with communities to reduce exposure to toxins typically found in tobacco smoke through sampling, enforcement, and education.
  • Support smoke-free policies and the work of environmental health professionals who advocate for healthy communities.
  • Tobacco harms in more ways than one. Children and pets are particularly vulnerable to second and third hand smoke.
