Project Name: Quantifying the Climate, Air Quality, and Health Benefits of Improved Cookstoves
Description: Emissions from open fires and rudimentary, traditional cookstoves have significant effects on climate, air quality and human health, but the design and implementation of cookstove interventions have been hampered by critical knowledge gaps. This project seeks to develop and apply a framework to quantify climate, regional air quality, and indoor air quality benefits of cookstove interventions. The project features an integrated program of multi-level laboratory and field emissions testing and field exposure monitoring that feed into indoor exposure and global air quality and climate models.

Project Name: NIH Human Exposure Study
Description: Approximately three billion people use traditional, inefficient and poorly ventilated indoor cookstove systems to meet basic energy needs, resulting in household air pollution responsible for 4.3% of the global burden of disease. Hundreds of millions of dollars are being spent on improved stove design and dissemination, yet the health benefits from specific stove technologies are unknown. In this study, the health-relevant emissions profiles for a variety of stove and fuel combinations is being characterized, and the association between markers of cardiorespiratory health and exposure to emissions from a broad range of stove technologies will be explored, informing future directions for stove programs while providing needed insight into the question, “How clean is clean enough?” This study is one of the first controlled human exposure studies ever conducted on developing world biomass cookstoves.

Project Name: Ultrasonic personal aerosol sampler
Description: We are designing new low-cost and low-burden personal exposure air samplers that drastically reduce the barriers to large-cohort exposure studies.The UPAS is a self-contained filter-integrated sampler featuring valve-less ultrasonic pumping technology to provide substantial reductions in size, weight, noise, and cost along with increases in durability vs. traditional sampling pumps. The UPAS features interchangeable inlets to affect PM2.5, PM10 or inhalable size-selective sampling onto an integrated filter. User interface for pre-programming, control and data download is via a Bluetooth-connected mobile app or USB cable connection to a computer. The UPAS is nearly silent and small and light enough to be worn in the ‘breathing zone’ of the user.

Project Name: Chemometer
Description: We are designing new low-cost traditional microfluidic and microfluidic paper-based analytic devices (μPADs) for the detection of metals in air and water samples. The μPAD uses a distance-based colorimetric detection method to quantify the amount of metal(s) contained in a sample. This work has been based upon previous traditional microfluidic and μPAD work that has been developed by the Henry Lab here at Colorado State University.
