Four-year community-wide PM2.5 exposure characterization using a low-cost sensor network in a rural valley influenced by residential wood smoke Open
Exposure to fine particulate matter (PM2.5) from woodsmoke is a national and global public health concern. While wood heat use is increasing in the Northeast U.S., exposure to woodsmoke in rural valleys in this region remains understudied.…

Impact of fueling protocols on emission outcomes for residential wood-fired appliances Open
Many believe that certification testing of residential wood heat appliances should provide data indicative of installed performance. Operationally, test methods typically only assess steady-state emissions and fail to include other typical…

Residential wood heating: An overview of U.S. impacts and regulations Open
Air pollution from residential wood heating poses a significant public health risk and is a primary cause of PM nonattainment in some areas of the United States. Those emissions also play a role in regional haze and climate change. While r…
