    Fires From Afar

    Health experts Mahdieh Danesh Yazdi and Nozomi Sasaki look at how climate change is increasing wildfire smoke exposure and related health risks. Host Heather Lynch, as well as Danesh Yazdi and Sasaki from Program in Public Health at Stony Brook University, discuss evidence linking airborne particles to increased mortality and cardiopulmonary impacts. They point to growing research, using large administrative datasets and local hospital data to assess impacts, that suggests wildfire smoke is more harmful than other pollution sources.

    Concrete Facts

    Marija Krstić, assistant professor of practice in the Department of Civil Engineering at Stony Brook University, is interested in cement production, which is a major source of global carbon emissions. Host Heather Lynch and Krstić explore the difference between cement and concrete, why steel reinforcements are essential for structural concrete, and how Portland cement – the binder, or glue in concrete production – requires high kiln temperatures, which releases CO2. Krstić explains why it is still unlikely that concrete is to be fully replaced with sustainable alternatives and changed methods in the near future.  Learn more with: “Field-Application-of-Recycled-Glass-Pozzolan-for-Concrete,” by Marija Krstić and Julio F.
