Live Chat: Our Toxic Environment
17 February 2013 2:20 pm
See below for the live video feed.
We live in a soup of potentially dangerous chemicals, from pesticide residues to lead in aging pipes and buildings. Many of these substances are toxic at certain doses; however, untangling their effects on our health can be extremely difficult. How can scientists tease apart exposure to chemicals from other health-related factors like diet? Which toxins should be avoided completely, and which are safe at low levels?
Join us from 3 p.m. to 4 p.m. EST on Sunday, 17 February, for a live Google+ Hangout to discuss the latest research on contaminants and our health with experts who track and measure their effects. Leave your questions for our guests in the comment box below. We will address them during the chat.
