Wildland Fires and the Environment: The Chemistry and Impact of Fire Emissions with Amara Holder

In this episode of the Pittcon Podcast, we interview Amara Holder, a research mechanical engineer at the US Environmental Protection Agency’s Office of Research and Development. We discuss the chemistry of wildfire emissions, particularly in urban interfaces. We explore the unique chemical characteristics of urban fires, advancements in monitoring technologies, community-driven solutions for smoke exposure, and the challenges faced in measuring emissions. The conversation highlights the importance of understanding wildfire emissions for public health and future research directions.

Amara Holder's research primarily focuses on pollutant emissions from combustion sources and their subsequent impacts on human health and the environment, with a particular emphasis on wildland fires.

Key Research Areas

🔥 Pollutant Emissions

Dr. Holder investigates the types and quantities of pollutants released during combustion processes, particularly in the context of wildland fires. This includes analyzing the chemical composition of emissions and their potential health risks.

☣️ Toxic Metals in Wildland Fires

A significant aspect of her research is the fate of toxic metals during wildland fires. This includes understanding how these metals are released into the atmosphere and their subsequent deposition in various environments, particularly in areas where wildland and urban interfaces overlap.

🌎 Health and Environmental Impacts

Dr. Holder's work aims to elucidate the relationship between pollutant emissions from wildland fires and their impacts on public health, particularly in vulnerable populations. This research is crucial for developing strategies to mitigate health risks associated with exposure to these pollutants.
