Bend Air: Is Juniper Ash Burning Summer Lungs?
By Franklin Everett ShawThe air hangs heavy, thick with the smell of pine and something else… something acrid. It’s a familiar scent to those of us who call Bend, Oregon home: wildfire smoke. But this year, it feels different. There’s a lingering, almost metallic tang that stings the nostrils and seems to burrow deeper into the lungs. Could it be the juniper ash from the recent prescribed burns mixing with the wildfire smoke, creating a particularly nasty cocktail? It’s a question many are asking, and one that deserves a closer look.
The Deschutes National Forest, surrounding Bend, is a tinderbox. Years of fire suppression have led to a dangerous buildup of dry brush and timber. Prescribed burns, carefully planned and executed, are intended to reduce this fuel load, lessening the risk of catastrophic wildfires. Juniper, abundant in the high desert, is often a target of these burns.
But juniper ash is different from other wood ash. It contains higher concentrations of certain minerals and compounds, and its fine, powdery texture allows it to remain airborne for longer periods. Could this unique composition be exacerbating respiratory problems when combined with the already harmful particulate matter from wildfires?
While definitive scientific studies are lacking, anecdotal evidence suggests a potential link. Many Bend residents report experiencing more severe coughing, wheezing, and shortness of breath during periods when both prescribed burns involving juniper and wildfires are occurring. The specific irritant in juniper ash hasn’t been isolated, but it’s plausible that certain compounds, when inhaled, trigger an inflammatory response in the lungs, making them more susceptible to the effects of wildfire smoke.
The challenge is that wildfire smoke itself is a complex mixture of gases and fine particulate matter (PM2.5), known to be harmful to human health. Separating the effects of juniper ash from the overall impact of wildfire smoke is difficult, requiring controlled studies that are both ethically and logistically challenging.
However, the absence of definitive proof doesn’t mean we should ignore the potential risk. As residents of Bend, we need to be proactive in protecting our respiratory health, especially during the summer months. Here’s a practical guide to navigating wildfire season in Central Oregon:
Monitor Air Quality Reports Diligently: Don’t rely solely on general air quality indices. Focus on PM2.5 levels, as these fine particles are the most harmful to your lungs. The Oregon Department of Environmental Quality (DEQ) provides real-time air quality data for various locations, including Bend and surrounding areas. You can find this information on their website or through the OregonAir app. Also, check PurpleAir sensors in your neighborhood. These are community-run sensors that often provide more localized and granular data than official monitoring stations.
Invest in a High-Quality Air Purifier: Look for air purifiers with HEPA (High-Efficiency Particulate Air) filters. These filters are designed to capture at least 99.97% of particles 0.3 microns in diameter, including PM2.5. Consider models with activated carbon filters to remove odors and gases. For larger homes, consider multiple units or a whole-house air purification system. Brands like Blueair, Coway, and Dyson are generally well-regarded, but research specific models to find one that suits your needs and budget.
Create a Clean Air Room: Designate a room in your home as a “clean air room.” This should be a room where you spend a significant amount of time, such as a bedroom or living room. Keep the windows and doors closed, and run your air purifier continuously in this room. Seal any cracks or gaps around windows and doors with weather stripping or tape to minimize air leakage.
Upgrade Your HVAC System’s Air Filter: Replace your standard HVAC filter with a MERV 13 (Minimum Efficiency Reporting Value) filter or higher. These filters are more effective at capturing fine particles than standard fiberglass filters. Be sure to check your HVAC system’s specifications to ensure that it can handle a higher MERV rating without reducing airflow.
Limit Outdoor Activities: When air quality is poor, reduce or eliminate strenuous outdoor activities. Even moderate exercise can increase your breathing rate and allow more pollutants to enter your lungs. If you must be outdoors, wear an N95 or KN95 respirator mask. These masks, when properly fitted, can filter out at least 95% of airborne particles.
Stay Hydrated: Drinking plenty of water helps to keep your airways moist and can make it easier to cough up any irritants that you may have inhaled.
Consider Nasal Irrigation: Using a saline nasal rinse can help to clear your nasal passages of dust, pollen, and other irritants. This can be particularly helpful after spending time outdoors.
Be Aware of Vulnerable Populations: Children, the elderly, and people with pre-existing respiratory conditions are more susceptible to the effects of air pollution. Take extra precautions to protect these individuals.
Advocate for Better Air Quality Monitoring and Mitigation: Contact your local and state representatives to express your concerns about air quality and the potential impact of prescribed burns and wildfires. Support policies that promote forest health, wildfire prevention, and improved air quality monitoring.
Understand the Limitations of DIY Air Filtration: While some DIY air filtration methods, like using a box fan with a furnace filter, can provide some benefit, they are generally less effective than commercially available air purifiers. They may not have the same level of filtration efficiency or airflow, and they may not be able to remove gases and odors.
One common mistake is assuming that if you can’t smell smoke, the air is safe. PM2.5 particles are invisible to the naked eye and can be present even when there is no visible smoke or odor. Always rely on air quality reports, not just your senses.
Another pitfall is neglecting to properly maintain your air purifier. Clean or replace the filters regularly according to the manufacturer’s instructions. A dirty filter will be less effective at removing pollutants and can even release trapped particles back into the air.
Finally, don’t underestimate the psychological impact of wildfire season. The constant threat of smoke and the disruption to daily life can be stressful and anxiety-provoking. Take care of your mental health by staying connected with friends and family, engaging in relaxing activities, and seeking professional help if needed.
The link between juniper ash and worsened respiratory symptoms in Bend during wildfire season remains a question mark. However, the potential risk is real, and we must take proactive steps to protect our lungs. By staying informed, investing in air purification, and advocating for better air quality management, we can breathe a little easier, even when the smoke rolls in. It’s about being prepared, being vigilant, and being a responsible member of the Bend community.
