Welcome to PSR's Environmental Health Policy Institute, where we ask questions -- then we ask the experts to answer them. Join us as physicians, health professionals, and environmental health experts share their ideas, inspiration, and analysis about toxic chemicals and environmental health policy.
Science
asks questions, and then tries to answer them. But the answers are constantly
evolving, due to increasingly precise measurements, advances in technology, and
creative breakthroughs in our conceptual framework. There is always more to
learn.
In
the field of environmental health, even our best-studied toxicants continue to
yield surprising revelations about their health effects. For example, lead,
long understood to be a powerful neurotoxin, is now known to affect other organ
systems as well, and at levels previously thought to be safe. New research
continues to clarify exactly how lead affects us, proving that we will never
know everything there is to know about the health effects of a given substance.
But
at what point do we know enough to try to protect people from detrimental
health effects? How can we ensure our safety, in light of the inevitability of
scientific uncertainty?

A lot is known about the dangers that meth lab chemicals pose to human health, but the public is largely unaware of that information. Educating the public about the health dangers that these homes present is vitally important to protecting the health of the public. Dawn Turner methlabhomes.com
