Families for Clean Air Launches Air Monitoring Network Focused on Wood Smoke Pollution

It has been well documented that wood burning devices create localized air pollution hot spots—but these neighborhood hot spots are often located far from official government air quality monitoring stations.

The result? A large number of households may be breathing highly polluted air, even when the established monitoring networks are showing the air quality to be good.

In an effort to address this discrepancy, Families for Clean Air has recently launched an air monitoring network in the San Francisco Bay Area.

The network utilizes PurpleAir PA-II air monitors to analyze the air quality of neighborhoods where there are currently no EPA or local air district monitors. The PA-II contains a sensor that uses a dual laser beam to count particles based on their reflectivity and provides real-time information about PM1.0, PM2.5, and PM10. This information can then be viewed on a map online–you can see air quality data at your home in real time, as well as information from other PA-II sensors.

Sound complicated? It isn’t. You simply attach the PA-II (about $250) to the outside of a structure, plug it into a power source, and connect it to your home’s Wi-Fi network. Readings are uploaded to the cloud every 80 seconds or so, where they are stored for download and displayed on the PurpleAir map.

Families for Clean Air is currently looking for more people in the San Francisco Bay Area to join this network, and will even help subsidize the cost of the PurpleAir monitors for qualified individuals. Please contact us to learn more.

Mapping wood smoke

February 21, 2018 The Goat News

Valemount has the worst air quality in the province as measured by the air quality monitor at the Valemount Fire Hall, but is that a good indicator of every neighbourhood in Valemount? Are some neighbourhoods smokier than others?

Last week a masters student from the University of British Columbia (UBC) and several local volunteers helped build a smoke map of Valemount.

Matt Wagstaff developed the project as a part of his masters thesis in Occupational and Environmental Hygiene at UBC’s School of Population and Public Health.

Wagstaff said occupational hygienists usually work in industries where populations are small and exposure to pollutants is high, so studying smoke exposure in BC communities took some ingenuity.

Last winter he worked on a method of measuring patterns of residential wood burning and developed a mobile monitoring system to take samples throughout town. You might have witnessed his slow moving vehicle driving systematically through just about every street in town last week.

“When people think of air pollution they typically picture a single point source such as an old mill or factory and you can see where the emissions are coming from,” he said.

But with wood smoke, there are many sources in the community due to residential wood stoves.

“There is high variability,” he said. “This will give us some idea of how the patterns vary and tell us how well the existing air quality monitor is placed,” he said.

The existing air quality monitor maintained by the province is located on top of the fire hall.

“The hope is to make this method available for community groups across the province to use this without charge,” he said.

Wagstaff is running the program in Valemount and in Golden, BC.

Sarah Henderson of the BC Centre for Disease Control said the air quality map will help better understand the problem.

“What that allows you to do is have better conversations with the people in the those neighbourhoods,” she said.

She said that there are easy options that help reduce the amount of woodsmoke.

“Educational campaigns can improve the way people are burning and it would be valuable for the entire community,” she said.

Want to keep tabs on local air quality? You can see air quality readings in real time (one hour delay) by searching the web for “valemount air quality.”

Do you struggle with respiratory problems that are aggravated on smokey nights? We’re interested in your story.

• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
