Reed Wins EPA Grant to Profile Diesel Exhaust
Reed partners with local agencies to examine health effects of diesel pollution.
"I feel privileged to be part of this collaboration. This is an exciting and unprecedented opportunity to comprehensively measure the components of diesel emissions to discern whether different sources have different composition, which could lead to varying health impacts." - Juliane Fry, Reed College Professor of Chemistry and Environmental Studies
Portland, OR—The Oregon Department of Environmental Quality is partnering with local colleges, community groups and government agencies to determine more precisely what’s in diesel exhaust and identify Portland areas most vulnerable to diesel pollution. The U.S. Environmental Protection Agency has awarded the group $466,276 for the two-year study.
Diesel exhaust contains a complex mix of very small particles coated in toxic pollutants that can enter the lungs and bloodstream. Different diesel engines produce different exhaust formulas, and the resulting air pollution resembles other “black carbon” pollution, such as smoke from wood stoves. Currently it is difficult to distinguish between pollution from diesel exhaust and other forms of black carbon pollution. This research aims to break down the many different sources of diesel emissions and identify new ways to monitor and mitigate its health effects.
“Whether it’s to tackle current or emerging environmental challenges, we need to link arms with the communities, researchers and all levels of government to leverage our resources and continuously refine how we evaluate the health of Oregon’s environment,” said DEQ Director Richard Whitman. “This grant is another step toward developing innovative methods to measure environmental conditions, trends and risks.”
Portland State University and Reed College will lead the research, working with project partners to identify monitoring locations in two vulnerable neighborhoods and around primary sources of diesel emissions: shipping areas, freight corridors, construction sites, and rail yards.
“Having access to better information about the sources and content of diesel pollution is key,” said Susan Anderson, director of the City of Portland Bureau of Planning and Sustainability. “Learning which areas of Portland are affected by the highest levels of diesel pollution will help the City of Portland and our partners find effective strategies to protect public health and address environmental justice concerns. We look forward to assisting with this important work.”
“We’ll be gathering data to create essentially a fingerprint of different types of diesel pollution,” said Linda George, Portland State University environmental science professor and lead researcher on the project. George’s colleague, PSU urban planning professor Vivek Shandas, will use land-use and demographic data to assess the vulnerability of communities in different neighborhoods to the effects of diesel emissions. Juliane Fry, Reed College chemistry professor, will be teaming up with George on monitoring, research and analysis.
Strategies for reducing exposure to diesel emissions could include cleaner diesel engines, reducing idling practices, altering freight routes and other measures to decrease the amount of diesel pollution reaching people. Project partner Multnomah County has been considering local options to reduce the health impacts of diesel emissions, and will be contributing data and analysis to further strategy development.
“Knowing more specifics about what’s in diesel and where it comes from will help us design community-driven strategies to reduce health risks from diesel pollution,” said Mary Peveto, director of Neighbors for Clean Air. “These strategies can have profound impacts for improving health, especially for our most vulnerable communities.”
