An Assessment of Indoor Air Quality in Hispanic Immigrant Housing in Commerce City, Colorado

• Project abstract
• Funded by a Department of Housing and Urban Development (HUD) Healthy Homes Technical Studies grant COLHH0123-04
• An indoor air quality assessment was conducted on 98 homes of recent Mexican immigrants in Commerce City, Colorado, an urban industrial community north of Denver. Homeowners were interviewed to determine housing quality, risk factors associated with pediatric asthma and other allergic diseases and exposures to particulate matter, carbon monoxide and carbon dioxide.

Identification, Classification, And Correlation Of Ultrafine Indoor Airborne Particulate Matter With Outdoor Values

• Project abstract
• Funded by ASHRAE, Project 1281-RP
• Many studies report that adverse health effects are most strongly correlated with fine particulate matter (< 2.5 μm in diameter), originating from ambient emissions mainly derived from fossil fuel combustion. This study examines the infiltration of ultrafine (0.055 - 0.7 μm) particulate matter into indoor environments including typical office space and elementary schools in an urban location, Denver, and a more rural location, Boulder.

Denver Air pollution Sources and Health (DASH) Study - A Source-Oriented Approach to Air Pollution Health Effects

• Project abstract
• Funded by NIEHS, research grant RO1 ES010197
• Improved understanding of the sources of air pollution that are most harmful
  could aid in developing more effective measures for protecting human health. The
  Denver Aerosol Sources and Health (DASH) study was designed to identify the sources of ambient fine particulate matter (PM2.5) that are most responsible for the adverse health effects of short-term exposure to PM2.5.

PM Exposure from Prescribed Burns and Wildfires

• Funded by US EPA Region 8
• Wildfires and prescribed burns are receiving increasing attention as sources of fine particulate matter (PM2.5). The goal of this research project was to understand the impact of mitigation strategies for residences impacted by scheduled prescribed burns and wildfires. We tested the effectiveness of keeping windows and doors closed or running an air cleaner for reducing exposure to PM2.5 during smoke events from the fire.

Indoor Environmental Factors and Childhood Asthma

• Funded by US EPA Region 8
• An intervention study was conducted in elementary school classrooms and homes to reduce childhood asthma symptoms, in collaboration with National Jewish Medical and Research Center. Air cleaners and HEPA vacuums were used regularly by one set of families, compared to the other set of families who did not participate in the intervention.
