As part of a special issue on chemicals for tomorrows Earth, weve got two green chemistry stories.

Sarah is also joined by Beate Escher of the Helmholtz Centre for Environmental Research and the University of Tbingen to discuss ways to trace complex mixtures of humanmade chemicals in the environment. They talk about how new technologies can help detect these mixtures, understand their toxicity, and eventually connect their effects on the environment, wildlife, and people.
