Lead is a study in contradictions. It’s dense enough to stop an X-ray, but soft enough to scratch with your fingernail. It’s heavier than steel and iron, but also more flexible. And, despite evidence of its toxicity, humans have been using it for all sorts of things for thousands of years . In this edition of our series “The Element of Surprise,” we hone in on this notorious heavy metal. What chemical properties make lead so harmful? How did something so dangerous become so ubiquitous? And if medical authorities acknowledge no amount of lead exposure is safe – especially for children – why do so many of us have lead in our water and our homes? Featuring Justin Richardson, Bruce Lanphear, and Chakena Perry. This episode was produced by Kate Dario. For the full credits and transcript, go to outsideinradio.org .
