Listen "Episode 3 - The Mad Hatter of It All: Trace Elements in the World Around Us"
Episode Synopsis
Episode Summary: It’s no secret that industrialization has taken a heavy toll on the planet and our bodies. But just how extensive and pervasive is chemical exposure? On this episode of Definitely not the Ivory Tower, Natalie Meisner sits down with chemists Nausheen Sadiq and Catharina Venter to discuss how we are exposed to toxic chemicals and metals on a daily basis, through water, food and cosmetics. This episode takes a look at the history of chemical contamination in everyday products, what the situation is like today, how our bodies and the environment are affected and how it can impact us over a lifetime. The two researchers also give advice on how we can deal with this reality and what to watch out for as consumers.
