Frying pans to polar bears: Using ice cores as a time capsule to understand pollutant transport.
Thousands of chemicals have been manufactured over the past century with the intent to improve our daily lives, but many of these chemicals end up contaminating areas far from their area of release, including the Arctic. Ice cores, which accumulate snow in layers that can be accurately dated, allow researchers to understand how pollutants were transported.
Dr. Cora Young, Assistant Professor and the Rogers Chair in Chemistry at York University, will discuss the importance of understanding how chemicals move around in the environment, the concern with Arctic contamination, and pollutant trends from Canadian Arctic ice cores.
