Air Quality


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

Climate Change and Built Environment

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.

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.

Newsletter Blurbs

World EH Day is a way of bringing together the global public and environmental health community to focus on an issue that needs attention and awareness. On September 26, 2016 we are partnering with the International Federation of Environmental Health and the National Environmental Health Association to raise awareness about second and third hand tobacco use as well the way EH professionals deal with tobacco use and exposure to environmental hazards.

Environmental Health and Tobacco

Tobacco use causes 20% of cancer deaths worldwide, and it is estimated that tobacco-related deaths will result in 10-million deaths annually by 2020. We've come a long way since the mid-1900's in understanding the negative health effects of tobacco to smokers.

Health Effects

  • Tobaccos smoke contains more than 7,000 chemicals. Hundreds are toxic and about 69 can cause cancer. 
  • Smoking is the leading cause of preventable death in the U.S. and causes over 438,000 deaths per year.
  • Secondhand smoke causes 41,000 deaths in the U.S. each year from heart disease and lung cancer.
  • While smoking is on the decline for both adults and students, there is still work to be done.

What Environmental Health Professionals are Doing

Environmental Health professionals conduct a variety of activities to control tobacco exposure, such as:

  • Investigate - Complaints and sample environments that may have unhealthy levels.
  • Enforce - Many municipalities across the county prohibit smoking in public places, so EH professionals enforce local codes, ordinances, and statutes restricting tobacco use. While there are not well-established exposure limits for tobacco smoke, there are many exposure limits for specific chemicals within tobacco smoke. Some of these chemicals have exposure limits for occupational settings.
  • Educate - Environmental Health agencies provide many educational resources and programs in awareness and tobacco cessation. They spearhead health campaigns to prevent illness and injury. Read about what local environmental health agencies are doing for their communities.
