The Times is launching an electronic newsletter called Saginaw Bay Watershed Watch.

It will include an expanded version of this Green Scene column in e-mail format, all the environmental stories that run in the paper, and a calendar of events going on in the 22-county Saginaw Bay Watershed….Michigan’s largest. To subscribe send an e-mail to sbww@bc-times.com  C’mon do it! Be engaged……….This watershed needs all our voices to restore it, to protect it and to ensure we have fishable swim-able waters for future generations.




 Dioxin, Public Health and Food for Thought


The following 2 articles were forwarded to me by physicians who found them relevant to the debate we are mired down in regarding the human impacts of Dow’s dioxin/furan contamination in our watershed.  A debate uncalled for given the thousands of independent studies demonstrating the impact of dioxin on human and ecological health. We need look no further than our backyard to see how, as the article so well states, the debate over science has become a debate over policy. We know it is in Dow best interest to manufacture uncertainty, it’s right out of the tobacco industry handbook- create doubt and insist on more and more research. At the end of the day it


The bigger question is who is permitting the debate over public policy with regards to this contamination. Are we to believe that there is so little independent science to support dioxin’s impact on humans that we can afford to be engaged in a debate with Dow to the detriment of public health and cleaning up our rivers? Of course there isn’t.  The link to the article from the Journal of Public Health is below---- the snips so relevant to our issue and Dow’s PR game.

Manufacturing Uncertainty: Contested Science and the Protection of the Public’s Health and Environment

David Michaels, PhD, MPH and Celeste Monforton, MPH


Snip: Opponents of public health and environmental regulation often try to “ manufacture uncertainty by questioning the validity of scientific evidence on which the regulations are based,…………


Snip: This strategy of manufacturing uncertainty in antithetical to the public health principal that decisions be made using the best evidence available….

Dioxin pollution leads to more baby girls –study

TORONTO (Reuters) - More girls than boys are born in some Canadian communities because airborne pollutants called dioxins can alter normal sex ratios, even if the source of the pollution is many kilometers away, researchers say.Dioxin exposure has been shown elsewhere to lead to both higher cancer rates and the birth of more females.Researchers at the IntrAmericas Centre for Environment and Health say their findings, released this month, confirm the phenomenon in Canada.The study also reveals the health risks of living within 25 km (15.5 miles) of sources of pollution -- a greater distance than previously thought, they said.http://www.reuters.com/article/healthNews/idUSN1836384520071018




EPA right in urging Dow to speed up work

Snip: Your editorial of Sept. 17th entitled "Our View:  EPA should finish its work" suggests that because the agency's dioxin reassessment is not yet completed, dioxin toxicity remains open to serious scientific debate. This is simply not true.

 Snip:    EPA has extensive scientific knowledge on the toxicity of dioxin. Thousands of peer-reviewed scientific studies have been published. No matter how you look at dioxin, one fact remains indisputable: dioxin is a highly toxic compound. In fact, EPA's reassessment of the most recent science indicated that dioxin is a more potent toxic chemical than previously believed. A recent University of Michigan study funded by Dow Chemical revealed that people consuming fish from the Tittabawassee River, Saginaw River and Saginaw Bay have higher than average levels of dioxin in their blood. Any increase in the   dioxin levels of fish consumers is a health concern.
