THREATS IN THE GREAT LAKES
ARE CHEMICALS REALLY THE CAUSE?
MR. MICHAEL GILBERTSON
October 16,
2001
Have our bodies become contaminated with
industrial chemicals? Are we suffering the ill-effects? If so, what can
we do about it?
As the first scientist to document effects of contaminants on Great
Lakes herring gulls, biologist Michael Gilbertson raised concerns about
the hazards of toxic chemicals in the Great Lakes basin. His findings
showed not only widespread contamination but also resulting damage to
other wildlife populations. Being concerned that what has occurred in
wildlife may be occurring in children, he has been working on human
health statistics for impacted communities in the Great Lakes basin for
the past three years.
Mr. Gilbertson earned his Master of Science Degree in Ecology from
Queens University in Belfast, Ireland, and moved to Canada in 1969.
After working with Environment Canada and later the Canadian Wildlife
Service, he joined the International Joint Commission, in 1988, as a
Physical Science Officer. Much of his present work is involved with
helping scientists translate their findings into information that is
accessible to other scientists, to politicians and to the general
public.

DIOXIN
ARE WE
ALL AT RISK?
DR. LINDA S. BIRNBAUM
December 5,
2001
Dioxin has been called one of the most
dangerous chemicals ever known. Purging uncertainties and clarifying
myths about dioxin, Dr. Birnbaum will discuss dioxin in general
where it
comes from, how we interact with it
and specifically, its staggering
impact on human health. She will also talk about dioxin effects in the
Great Lakes.
Dr. Linda S. Birnbaum serves as lead scientist and director of health
research in the U.S. Environmental Protection Agency's (EPA) dioxin
reassessment.
She is currently Director of the Experimental Toxicology Division,
and Acting Director of the Human Studies Division, at the National
Health and Environmental Effects Research Laboratory, Office of Research
and Development, U.S. EPA. Dr. Birnbaum received her Ph.D. in
Microbiology from the University of Illinois at Urbana in 1972, with a
minor in Biochemistry.

HIDDEN IMPACTS OF PESTICIDES
ARE THEY OCCURRING HERE?
In independent research, the Guillettes
have shown that pesticides can undermine intelligence, impact behavior,
and diminish reproductive capacity. The sobering fact is that these
deficits occur without any obvious signs of poisoning.
Lessons from the
Swamp
DR. LOUIS J. GUILLETTE
February 6,
2002
The lakes of central Florida have received
contaminated run-off for decades. In 1980, a pesticide spill further
contaminated Florida's Lake Apopka. During the 1990s, Dr. Louis
Guillette and his colleagues discovered serious developmental
deformities in the lake's alligators and fish. His discovery and ensuing
work has shown that the lake's contaminants alter normal embryonic
development. He has begun to understand how complex mixtures of
pesticides affect environmental health of freshwater ecosystems.
Dr. Louis J. Guillette is a Professor of Zoology at the University of
Florida. He earned his undergraduate degree from New Mexico Highlands
University and his Ph.D. in Biology from the University of Colorado at
Boulder. He reviews grants for the National Geographic Society, the
National Science Foundation, the National Institutes of Health, NATO,
and the Environmental Protection Agency.
From the Swamp to
the
Great Waters

ELIZABETH A. GUILLETTE

Children from two similar towns nestled in
the Yaqui Valley, one of Mexico's largest agricultural areas,
demonstrate startlingly different neurological capabilities. Dr.
Elizabeth Guillette's ground-breaking work shows pesticide exposures
account for the diminished abilities of one group
the
children lack energy, are saddled with significant learning
disabilities, and have coordination problems. Many of the pesticides
used in this area are in use throughout the United States and
Canada.
Dr. Elizabeth A. Guillette is known for her anthropological
interpretations regarding the interplay between contaminants, human
health, and society. She received her Masters in Nursing Education in
1963 from the University of Rochester. She earned her Ph.D. in Applied
Anthropology from the University of Florida in 1992. She is currently a
Distinguished Visiting Scholar at the Center for Bioenvironmental
Research at Tulane and Xavier Universities, and a Visiting Professor,
Interdepartmental Honors, at the University of Florida.

INTELLECTUAL IMPAIRMENT IN
MICHIGAN CHILDREN FROM
PCB
CONTAMINATED FOOD
DR. JOSEPH JACOBSON
April 10,
2002
"Significant and enduring" describes the
problems occurring in children contaminated with PCBs. Once used as
coolants and lubricants in electrical equipment, PCBs
polychlorinated biphenyls
have settled into the food web from whence
they find their way into embryos, infants and others. Measurable
quantities of PCBs circulate throughout Michigan.
Dr. Joseph Jacobson and his collaborator, Sandra Jacobson, have been
investigating the impacts of environmental contaminants in the Great
Lakes for the past 20 years. Based on their findings, Dr. Jacobson will
discuss how PCBs, an industrial pollutant, can move into the womb and
influence the developing baby, leading to changes in a child's general
IQ level, verbal skills, capacity to pay attention, reading
comprehension, and physical coordination.
Dr. Jacobson's work focuses on developmental psychology
the study
of physical, cognitive, and social changes from conception to death
and looks
at how our ever-changing environment can influence behavior. He is a
Developmental Psychology Professor and Chair of Psychology at Wayne
State University.

THE MAKING OF A CONSERVATIVE ENVIRONMENTALIST
MR. GORDON K. DURNIL
May 16,
2002
Addressing the fact that persistent toxic
chemicals subtly compromise human health
often in irreversible ways
Mr.
Durnil tackles the issue of solving the problem. Acknowledging that most
people doubt the truth, he will talk about the value of overcoming
deeply ingrained points of view in light of overwhelming scientific
fact. He will also discuss the crucial role individuals can play in
protecting human and environmental health.
Appointed by former President George Bush to be Chairman of the
United States Section of the International Joint Commission, Mr. Gordon
K. Durnil served from 1989 - 1994. He is an internationally recognized
expert at resolving environmental disputes between nations.
Mr. Durnil is the author of The Making of a Conservative
Environmentalist (1995), and Is America Beyond Reform (1997),
and contributed a chapter to Protecting Public Health & the
Environment: Implementing the Precautionary Principle (1999). He
also wrote Throwing Chairs and Raising Hell: Politics in the Bulen
Era (1999).
He earned his Bachelor of Science Degree from the Indiana University
School of Business and his Doctor of Jurisprudence Degree from the
Indiana University School of Law. His law practice concentrates on
probate, governmental, and administrative law as well as charitable,
campaign, and environmental law.
