Pharmaceuticals are an important technology in our world that help save so many people. But sometimes, drugs that are good for humans can get into our water supplies and harm other organisms. But why is something helpful for us, but hurtful for other animals? On this episode of the Let's Talk Chemistry, hosts Nicholas Molitor, Olivia Lambertson, and Yeongseo Son talk about their interview with Dr. Damià Barceló, a Professor of chemistry at the Institute of Environmental Assessment and Water Research and a Scientific Director of the Institute for Water Research in Catalan, Spain. We talk about unlikely contaminants in water, the environmental impact of the COVID-19 pandemic, and the harm of plastics in our environment. We hope you enjoy! If you would like to know more about Dr. Damià Barceló, you can check out his research or reach him by email at [email protected].
