Air Quality can affect many aspects of our daily lives.  The AQCP addresses ambient air quality through its monitoring efforts and also indoor air quality through its wood and coal stove outreach efforts and indoor air quality assessments.  However, due to the complexity of air quality, there are additional sources that have an impact on ambient air quality concentrations.  Wildland fires, and prescribed burns have a significant effect on our air quality and our overall health.  Below is a list of helpful links that provides more information on wildfire activities and prescribe burns in the Four Corners area.

1. Is the Navajo Nation within attainment or non-attainment status?

The Navajo Nation is designated as Class II status and therefore is designated as "unclassifiable/attainment" for the National Ambient Air Quality Standards (NAAQS) for criteria air pollutants within Arizona, New Mexico, and Utah. 

2. Out of the six criteria pollutants, what is measured on the Navajo Nation?

Nitrogen dioxide, sulfur dioxide, ozone & particulate matter (PM10 & PM2.5).

3. What is particulate matter? How small are PM10 and PM2.5 in µg/m3?

Particulate matter (PM10 and PM2.5) contains solid particles or liquid droplets small enough to stay afloat in the air for weeks. Particulate matter is a major concern to public health because the particles are small enough to be inhaled into the lung which can cause respiratory problems such as asthma. PM10 is about 1/7th the thickness of a human hair. Fine particulate matter known as PM2.5 has a specific range of particles 2.5 micrometers or less. PM10 is a major component of air pollution that threatens our health and the environment. Particulate matter is created by variety of sources including traffic on unpaved roads, mining, earth-moving machinery, and construction sites.



 4. Can Navajo Nation Chapter request assistance on collecting some air monitoring data within their community?

The AQCP also responds to citizens’ concerns regarding ambient air quality in a community.  The program has the ability to deploy one mobile unit which is equipped with a gaseous monitor, and an Environmental Beta Attenuation Monitor (EBAM) which measures for particulate matter.  Requests for community air monitoring is considered on a case by case evaluation, please contact the program for further information.

5. Does NNEPA AQCP provide outreach activities or presentation?

Yes, our program provides information at local chapter meetings, community health fairs, classroom activities, environmental conferences and upon request. If you would like additional information on outreach presentations or to schedule one, please do not hesitate to call our office at 928-729-4246.

6. What is an Air Quality Index?

It is an indicator used to determine the air quality, based on pollutants that have adverse health impact on the human health and the environment.

7. What are some of the health effects from air pollution?

Coughing and wheezing, dry throat, irritation of mucous membranes, headache, and nausea.

8. What is air pollution?

Air pollution as defined by the Navajo Nation Air Pollution Prevention and Control Act “is the presence in the ambient air of one or more air pollutants or combinations thereof in sufficient quantities, which either alone or in connection with other substances, by reason of their concentrations and duration, is or tends to be injurious to human, plant, or animal life, causes damages to property, unreasonably interferes with the comfortable enjoyment of life or property of a substance part of a community, obscures visibility, or in any way degrades the quality of the ambient air.”
