Professor Winer's research program focuses primarily on experimental and modeling studies concerned with air pollutant exposure assessment, with an emphasis on children's exposure to toxic air contaminants, including diesel exhaust. With UC Riverside researchers, Dr. Winer?s research group conducted an extensive study of children?s exposures on diesel school buses and in related microenvironments, demonstrating for the first time the phenomenon of self pollution in such buses, and identifying the important variables which determine children?s exposures. In a pilot study, ahead of a much larger state study, measurements of toxic air contaminants and ventilation rates in portable classrooms were conducted in southern and northern California. More recent research has involved applications of an instrumented electric vehicle, or mobile platform, to measurements in several locations in the California South Coast Air Basin heavily impacted by mobile source emissions, including communities adjacent to the Ports of Los Angeles and Long Beach, and in downtown Los Angeles and Boyle Heights. Among other findings, this research led to the discovery that the impacts of major roadways can extend ten times further, and result in higher pollutant concentrations, in the pre-sunrise hours than during the day, despite lower traffic volumes before sunrise. This finding has health implications for near-freeway
residents since most people are in their homes in the pre-sunrise hours.
Mobile platform measurements in port- adjacent communities demonstrated the impacts of heavy-duty diesel trucks on roads and in near-roadway environments, and raised significant environmental justice concerns for residents. A mobile platform study at the general aviation airport in Santa Monica, California characterized the intrusion of jet aircraft emissions into the downwind neighborhood.
The overarching goal of Professor Winer?s field-based research projects is to more accurately characterize air pollutant exposures in critical microenvironments where people spend their time, rather than relying on data from a limited number of monitoring stations measuring area-wide outdoor ambient air pollutant concentrations.
