A little exposure to natural outdoor areas might go a long way toward
easing the symptoms of attention deficit hyperactive disorder in kids.
The Great Lakes Radio Consortium’s Tom Rogers has more:
Previous studies linking the outdoors to relaxation prompted University
of Illinois researchers to survey the parents of more than 400 children
diagnosed with ADHD. The researchers asked parents to monitor
their kids’ behavior and performance after play or study periods
indoors, outdoors in an urban setting like a parking lot, and outdoors
in greener areas.
Francis Kuo co-authored the study. She says the natural settings
seemed to improve symptoms.
“This doesn’t have to be something spectacularly natural. Just getting
your kid out in a green, tree-lined street would be good, or in the
backyard, or even the neighborhood park. You don’t have to take them
to Yosemite for these benefits.”
The study didn’t make any conclusions about whether nature could take
the place of medication, but Kuo says there’s a real potential that it
could at least help kids who don’t tolerate drug treatment well. The
study appears in The American Journal of Public Health.

The latest report on the overall health of the Great Lakes shows
mixed progress in cleaning up the lakes. The International Joint
Commission says there have been some improvements, but there are
still many areas that need to be worked on. The Great Lakes Radio
Consortium’s Stephanie Hemphill reports:
The IJC is an agency made up of Canadian and U.S. officials who
monitor the overall health of the Great Lakes. Every two years, the
agency issues a report.
This year’s report says the two governments have made progress in
cutting releases of many toxic chemicals. And scientists are closer to
understanding how global climate change is likely to affect the Great
Lakes.
But the report says other issues require urgent attention. It calls for
government action to reduce mercury emissions from coal-fired
power plants. Mercury can cause nerve and developmental damage
when it’s eaten in fish.
And U.S. Co-Chair Dennis Schornack says the governments should
do more to stop invasive alien species from getting into the Great
Lakes.
“We still don’t have measures in place that would stop ballast water
mediated transfers of species from abroad; we’ve still got a threat
with the Asian carp coming up the Chicago Ship and Sanitary Canal
and incomplete funding for the barrier to stop that invasion there.”
The report also urges scientists to figure out why Lake Erie’s water
quality is degrading again, after years of improvement.
And there are always new challenges, according to Canadian Co-Chair Herb Gray.
“There are new families of chemicals getting into the water. The fire
retardants, which are great for your furniture, but not great in drinking
water.”
This was the 12th biennial report on Great Lakes water quality. The
report says it’s now time for a comprehensive review of the
agreement between the U.S. and Canada to clean up and protect the
Great Lakes.

The American Bald Eagle is expected to come off the endangered species
list soon. Once a victim of hunting and pollution, the eagles are
rebounding, but scientists say monitoring must continue, for the sake
of the eagles and the sake of the environment. The Great Lakes Radio
Consortium’s Bob Kelleher reports:
If you’re looking at all, it’s hard to miss the bald eagles here. The
majestic birds glide overhead, or silently perch on a waterfront tree.
Their nests – made of branches – fill the treetops – sometimes ten feet
across, close to the lakes of Northern Minnesota’s Voyageurs National
Park.
Twenty years ago you might have been hard pressed to spot America’s
national symbol. Park Biologist Lee Grim says, it was obvious that
eagles were struggling.
“We saw how some of these birds were ill, and sick, and they had avian
pox and things. Something was keeping them from being healthy.”
An eagle found here in 1989 had the highest blood concentration ever
found of contaminants like the chemical PCB.
“So, we wanted to know why is that up here in Northern Minnesota, in
the middle of a beautiful, you know, almost wilderness area.”
It’s still a mystery how industrial chemicals like PCB’s get here, but
we do know what’s hurt the bald eagles in the past. The insecticide
DDT made bird eggs fragile – more likely to break under an eagles
weight than hatch. And Grim says DDT was all over the place. It was
sprayed on the region’s forests to kill insects like the spruce
budworm.
“DDT is pretty much everywhere, it has been, you know. And it’s a
pretty long lived chemical.”
At the top of the food chain, chemicals like DDT accumulate in the
eagle’s bodies. Sick eagles can indicate a poisoned environment. To
test the environment, you test the eagles.

A naturalist is scaling 90-feet up one of the park’s White Pine trees
to the huge nest at the top. The parent eagles circle overhead –
noisily upset. There’s a pair of hatchlings – fuzzy, beaky, and
surprisingly big 8-week old bald eagles. They have bright yellow feet,
with shiny black, and what will become very dangerous talons. Soon,
one’s squirming in an orange bag, and lowered into the hands of
graduate students Faith Wiley and Katie Parmentier.
(snd of students talking about baby eagle)
In minutes, the young female is back up; short a few feathers for
mercury testing; and a little blood for other chemical tests. There’s
a pair of metal bands riveted around her ankles.
Bill Bowerman is an environmental toxicologist from Clemson University.
His testing proves that chemicals like DDT and PCB’s are slowly going
away, but chemicals were only part of the problems for bald eagles.
Man was another problem. It took decades to get people to stop
shooting eagles; or to catch them accidentally in beaver traps, but
it’s better now.
“It’s evident, when I go out to landowners that have eagle nests on
their property, that they know how to manage their eagles; how to keep
people away; and how to protect that eagle during that critical nesting
period.”
It’s believed there were once half a million bald eagles in North
America. As people spread, by the 1950’s, bald eagles nearly vanished.
In the lower 48 states, the last few hung on in places like the Great
Lakes.
In Voyageurs Park, bald eagle numbers have jumped from seven nesting
pairs in 1973, to 28 pairs today. There are more than 7-thousand
breeding pairs nation wide, but there are always new threats. One of
the nation’s first victim’s to West Nile disease was the bald eagle in
New York area zoos. Bowerman says several pair are missing now in
Michigan, and there are always new chemicals. Traces of poly
brominated flame retardants are doubling in the Great Lakes basin every
3 to 5 years. Bowerman says the chemical industry needs strict
monitoring.
“As long as we maintain our vigilance about the environmental toxicants
that are being created each year, we should be having the eagles
protected.”
Bowerman supports de-listing, but doesn’t want the birds in the
predicament they were twenty years ago. An official announcement of
the bald eagle’s de-listing is expected later this year.

The Environmental Protection Agency says it’s trying to get states around the Great Lakes to use
uniform standards to monitor water quality. But the EPA says the fact that different states use
different methods doesn’t put anyone at risk. The Great Lakes Radio Consortium’s Stephanie
Hemphill reports:
The agency is responding to a report from the Environmental Integrity Project. That group says
different states have different standards, and that means no one has a clear idea of how clean – or
dirty – our rivers and lakes really are.
Thomas Skinner is administrator of EPA’s Region Five. He says the Clean Water Act allows
each state to design its own program.
“It may be that some states are being overly protective or over protective of their citizens, and
that’s their right to do it. But if that’s the case, then that could explain some of the
inconsistencies. It doesn’t mean the states that have a different set of fish advisories are not
protecting their citizens; they’ve just chosen to go about it in a slightly different way.”
Skinner says the EPA asked the states seven years ago to use the same standards. He says the
states are gradually moving toward that goal.

The heightened security following (Tuesday’s/last weeks) terrorist attacks is extending to the Great Lakes. The Great Lakes Radio Consortium’s Jonathan Ahl reports:
The U-S Coast Guard is increasing patrols, and closely monitoring every ship that is navigating the Great Lakes. It is also adding patrols to the St. Lawrence Seaway and the St. Mary’s River.
There are no specific new regulations in place, but the Coast Guard is evaluating each vessel on a case-by-case basis. The Guard also has the authority to restrict any movement or remove ships from ports.
The Coast Guard is also increasing security at its own ports, and has restricted access to all Coast Guard Buildings and vessels.
The Secretary of Transportation gave the increased authority to the Coast Guard shortly after the attacks. There is no timetable for how long the heightened security measures will be in place. For the Great Lakes Radio Consortium, I’m Jonathan Ahl.
