In the second podcast of this series, we look at the extraordinary number of chemicals that have been created, produced and in use, what inventories exist on these chemicals, how much we know about their toxicity and potential for harm, and how well they are regulated. We’ll also explore the legislative, regulatory and other interventions needed to better manage, reduce and prevent chemical pollution. This episode is hosted by Charles Goddard, editorial director at The Economist Group, he is joined by Dr Zhanyun Wang, scientist at the Swiss Federal Laboratories for Materials Science and Technology, and a leading thinker on this issue.
