  2. Study Overview • 16 participating households • Sampling before/after changeout • Ambient PM2.5 mass • Indoor PM2.5 levels and chemical markers of woodsmoke • Woodstove change out • Outreach and education

  3. Ambient Monitoring • Utilized existing network • PM2.5 TEOM • Met Site: temperature, RH, precipitation, wind speed • EPA PM2.5 standards • 24/hr is 35 μg/m3 • Annual is 15 μg/m3

  4. Indoor Sampling • Equipment • DustTrak (Model 8520) • Leland Sampler / Personal Environmental Monitor (PEM) with a quartz filter • Data Collection • Sampled for 24-hour period, one to five sample days • Intern sampling duties • Participant responsibilities

  5. Stoves Old

  6. From Old to New

  7. Indoor PM2.5 Mass Comparisons

  8. PM2.5 and OC/EC/TC(Homes with Complete Datasets)

  9. Chemical Markers of Woodsmoke(Homes with Complete Datasets)

  10. PM2.5 Mass Following Outreach/Education 2412.0 322.7

  11. Outreach and Education Lessons Learned • New stove learning curve • Less is more • Be specific. Step by step directions

  12. Challenges • Sampling equipment malfunctions • Distance to Kamiah from Lapwai • Homeowner • Learning curve with new stove • Paperwork, no shows • Selecting 4 new homes mid-study • Woodstove business & installer • Distance (~200 miles away) • 2nd round of installations delayed two months due to snow • Attitude/not vested in the community

  13. Outcomes/Successes • Partnerships & intern participation • Reduced ambient PM2.5 in each community • Reduced indoor levels • PM2.5 levels by 52% • Levoglucosan by 63% • 16 tribal homes with EPA certified stoves • Outreach and Education
