A recent study indicates expectant mothers who are exposed to
air pollution see damage to the genetic make up of their newborns.
That might increase the babies’ risk of contracting cancer later in
life. The Great Lakes Radio Consortium’s Lester Graham reports:
The expectant mothers were asked to carry air monitors in backpacks to see how much they were exposed to air pollutants. The Columbia University researchers chose 60 mothers in low-income neighborhoods. Dr. Frederica Perera is chief author of the study.
“All of our mothers in the study were non-smokers. So, the primary source of these pollutants in air would be things like motor vehicles, emissions from residential heating units, burning fossil fuel and also from power plants located even fairly far away.”
It’s the fist study to make a connection between air pollutants causing genetic changes in the womb that could increase cancer risk. Earlier studies by the researchers already revealed greater prenatal exposure to air pollution caused lower birth weights and smaller heads in newborns.
Smokestacks, diesel engines, and a number of other things cause particulate emissions, which can create some negative health effects, and aggravate existing health problems. (Photo by Kenn Kiser)
In the summer, local weather forecasts often
include information about dangerous ozone levels.
But scientists are learning more and more about
another type of pollution that can reach harmful
levels even in the winter months. And as the Great
Lakes Radio Consortium’s Sarah Hulett reports… we

In the summer, local weather forecasts often include information about dangerous ozone levels. But scientists are learning more and more about another type of pollution that can reach harmful levels even in the winter months. And as the Great Lakes Radio Consortium’s Sarah Hulett reports, we might be hearing more about this type of pollution in our daily weather reports:
Parts of the region recently reached “code red” for poor air quality. And
that had some people perplexed. Warnings about dangerous levels of ozone are
frequent on hot summer days, especially in urban areas. But this was the
middle of winter.
The warnings were for high levels of tiny particles that federal regulators
only recently began monitoring. They’re spewn from diesel engines,
factories, power plants, and fireplaces. Air monitors in Michigan,
Minnesota, Pennsylvania, and Indiana recently registered unhealthy levels of
these particles – some of them for a few days straight.
Jim Haywood says the problem was an unusual weather event for this time of
year. Haywood is a meteorologist with the Michigan Department of
Environmental Quality. He says a high pressure system moved very slowly over
the Great Lakes region for several days. When you get high pressure, the air
below sinks, generating a layer of warm air that acts like a lid.
“So that warm air that was sinking effectively stops at a few hundred feet
from the surface of the ground. It acts like a cap. It does not let any of
the pollutants that are released at the surface pop up through that cap.”
So all the pollutants that would have gotten picked up and diluted by the
wind instead just hung out for days – building up, and reflecting sunlight
to create haze.
Eventually, a cold front pushed the high pressure system out of the way, and
took the pollution with it. But what about those few days when the Environmental Protection Agency was warning about unhealthy levels of particulate pollution? For people with
heart or lung disease, agency health officials say short-term episodes can
lead to asthma attacks or even heart attacks. And they say healthy children
and adults can experience throat and lung irritation.
Susan Stone is an environmental health scientist with EPA. She says
particle pollution warnings could soon become a staple of the daily weather
report – much like the familiar summer ozone warnings.
“With ozone, we have the network in place to be able to deliver those
forcasts, people are used to hearing that on TV, and we are working to
provide that same level of coverage for particle pollution.”
Stone says EPA is rolling out a new program called Enviro-Flash
nationwide. It sends real-time air quality information to people’s email
accounts or pagers. EPA is offering the service through state
environmental agencies. And beginning in 2010, areas that register
unacceptable levels of particle pollution will be required to clean up their
air.

Several state attorneys general are urging the Nuclear
Regulatory Commission to upgrade security at nuclear power plants
to defend against terrorist attacks. The Great Lakes Radio
Consortium’s Lester Graham reports:
The Nuclear Regulatory Commission has stepped up security at nuclear power
plants since the terrorist attacks on September 11th, 2001, but it’s still
using a defense plan designed 35 years ago based on four men attacking by
land.
A nuclear watchdog group called Committee to Bridge the Gap has filed
a petition with the NRC, asking that the plan be updated to take into
account the methods and numbers terrorists have actually used. Seven
attorneys general signed a letter supporting the security update. Paul
Laraby is with the New York Attorney General’s office.
“I think what the AGs are trying to do is to introduce common sense
approach to an emerging threat that perhaps was discounted thirty-five years ago.”
Even after more than three years since the attacks, the NRC still has not
determined how it should upgrade the its defense plans for nuclear power
plants.

Nuclear power plants need enriched uranium to produce power.
Today, there’s only one uranium enrichment facility operating in the
U.S. Now, there’s a proposal to build a new one in southern Ohio.
And as the Great Lakes Radio Consortium’s Fred Kight reports, there’s
debate over how safe the proposed plant will be:
The one-point-five billion dollar project is planned by USEC, Incorporated, the world’s largest producer of enriched uranium. Company officials say it would generate 500 jobs and be built at the site of an old, off-line uranium enrichment plant. Charles Wiltshire is still employed there and he’s all for building the new facility.
“I would like to see future job opportunities for my children and grandchildren who will be finishing college about the time the centrifuge plant is due to go online.”
But environmentalists and concerned citizens are worried about the radioactive waste. They’re also fearful of water pollution and health hazards for plant workers. The State of Ohio has promised more than 100 million dollars in financial incentives and is confident that the new plant will not put anyone in danger. The Nuclear Regulatory Commission is reviewing the company’s application and is supposed to make a decision by early 2007.

Transcript
With no power lines in sight, one western Pennsylvania couple lives pretty much like the rest of us. The Great Lakes Radio Consortium’s Ann Murray has this story of home “off the grid”:
Ted Carns is busy hanging art in the foyer of his house. While he holds a picture in place against the wall, he plugs in an electric drill.
(sound of drill)
Ted and Kathy Carns’ entire two-bedroom house uses electricity powered by the sun or wind. Their rustic stone and plank home sits on top of a steep wooded hill, miles from the nearest neighbor.
“There’s no water, there’s no soil, there’s no public utilities up here. So everything that we designed, you have to keep in mind, was done in this harsh condition.”
It’s taken the Carns twenty years to design and expand their alternative energy system. Ted, a self-described scrounger and handyman, has found many components through flea markets and friends. In fact, Kathy says their off-grid system began with a gift of shoebox-sized batteries.
Kathy: “Somebody gave us a bunch of batteries-nickel cadmium batteries. And then we started thinking about how to recharge the batteries. Thinking wind. The windmill came first.”
Ted: “It took me eight climbs to install the new windmill, I had a different one up there. The bottom of the tower I built.”
Murray: “How tall is that?”
Ted: “Seventy-six feet.”
(sound of chimes)
The metal tower now looms over the house, outbuildings and organic garden. As the wind whips the chimes at its base, the turbine blades whirl and drive an alternator to generate electricity. The electricity is stored in a bank of batteries.
Murray: “Is the wind consistent here?”
Carns: “Winter good. Summer not. Then in summer the solar panels kick in. So it just sort of balances out.”
The Carns’ rooftop solar panels accept sunlight into silicon chips and convert the light into electricity. Because it’s sunny today, Kathy can run their specially manufactured clothes washer with solar energy. First, she pushes a button on the living room wall and a red light starts to blink. The light indicates that stored electricity is being converted from a DC to AC current.
“That means the house is on 110 power. Turn the water on and then just… It’s on.”
The Carns also vacuum when the sun shines or the wind blows. They run their TV, stereo and lights off 12-volt DC batteries, much like a car. They heat their water with solar energy in the summer and wood in the winter. And warm their house with a wood stove. They also capture air from underground and use it to refrigerate food and cool their house. All told, Ted and Kathy have spent about 3,000 dollars to upgrade their alternative energy system. Ted says, except for burning wood, the system is nonpolluting. He believes it’s also pretty much hassle free.
Carns: “There’s no inconvenience that we’ve seen… There’s maybe two or three days that we don’t have ample hot water. The nice thing about that is that it – you never stop appreciating the conveniences because periodically for a very short time sometimes you have to do without.”
Perez: “More and more people are discovering that they can power their homes and small businesses using solar and wind.”
Richard Perez is the founder and publisher of Home Power Magazine. Perez says states are doing far more than the federal government to encourage the residential use of renewable energy.
“There are tax credits, there are rebates, there are buy-downs. Every state has a slightly different scheme but most states have some sort of financial incentive for installing small-scale renewables in your home.”
Perez says homeowners don’t have to wait wait for government support to set up a system. Ted and Kathy Carns agree.
(sound of plates and silverware)
As the couple gets ready for dinner, Kathy says they want to inspire the many people who come to see how they live off-grid.
“We have a friend who has a solar lawnmower now. We have friends in Philadelphia that took some solar panels; it’s not their total system, but it’s a little part of their system. If we get enough company and enough people have been here, it sort of branches out, and goes off.”
An estimated 180 thousand households in the United States generate some or all of their own electricity. But alternative energy systems aren’t for everybody. For people who are downright afraid of technology or inconvenience, life off the power grid isn’t a real option just yet.

Automakers from around the world spent last week showing off their latest concepts and production cars at the North American International Auto Show in Detroit. Many car companies announced plans to begin producing more hybrid vehicles. As the Great Lakes Radio Consortium’s Bill Poorman reports other environmental technologies got some attention as well, including a new way to use hydrogen to fuel the vehicles of the future:
Many automakers now say that cars ultimately will be powered by hydrogen fuel cells. Fuel cells consume hydrogen to generate electricity to power a motor, while leaving on water as waste. There are problems with cells. They’re really expensive right now. And there aren’t many hydrogen re-fueling stations. Ford Motor Company thinks it has a solution. It’s converting some standard gasoline engines to burn hydrogen. Ford’s chief engineer for the system, Vance Zanardelli, says the new engine is a necessary step.
“In order to get people familiar with hydrogen as a fuel, realizing it is a clean, safe fuel, in order to help spur the development of more hydrogen fueling stations, the development of revised codes and standards, and really lay the groundwork, so that when fuel cells are ready for primetime, the world is ready for them.”
Ford plans to begin testing some of the new hydrogen-burning engines in shuttle busses next year.

Coal-burning power plants from Great Lakes states are often blamed for much of the pollution that hits the East Coast. But now, the federal government is proposing a massive research project that they say could eventually perfect a way to burn high-sulfur coal without sparking pollution. The Great Lakes Radio Consortium’s Bill Cohen has this report:
The feds are proposing a massive one-billion-dollar plant that’s billed as the world’s first non-polluting, coal-burning power plant. About twenty states say they’ll compete for it. Ohio is one of them. Mark Shanahan of the Ohio Air Quality Development Authority says the plant will first turn coal into gas. And then either recycle or safely store the by-products.
“And when it turns to gas, it’s able to pull out the pollutants much more efficiently and economically. It will pull off hydrogen for fuel cells and it will also test the ability to put carbon dioxide into very deep geology to basically bind it up forever deep in the earth.”
The U.S. Energy Department will pay for most of the plant, but it will be several years before it’s actually online.

Cars, trucks, and coal-fired power plants contribute to fine particle pollution, or soot. That type of pollution can be harmful for adults with heart or lung problems, and kids with asthma. A new study suggests that the pollution can also affect developing babies. The Great Lakes Radio Consortium’s Rebecca Williams has more:
This study was the first to look at fine particle pollution and developing babies in the U.S. Researchers looked at more than 18,000 babies that were carried to full term in California. They found that mothers living in areas of high exposure to fine particles had babies that weighed about an ounce less than mothers living in low exposure areas.
Tracey Woodruff is a senior scientist with the Environmental Protection Agency. She co-authored the study in the journal Pediatrics. Woodruff says an ounce is a small difference in birth weight, but it’s significant enough to merit more research on particulate matter – also known as “p.m.”
“This is one more piece of information about adverse health effects of p.m., which is feeding into the larger literature, which is leading EPA to embark on a number of different activities to try to reduce the levels.”
Woodruff says future research should look at whether fine particle pollution is related to premature births.

Buffalo has become the first city in the Great Lakes region to pass a law aimed at curbing the amount of toxic chemicals entering the environment. As the Great Lakes Radio Consortium’s Joyce Kryszak reports, officials hope to accomplish this goal by changing their buying habits:
Every day, cities buy tons of office supplies and other products containing toxic chemicals. When these products are discarded, they eventually break down and sometimes leach toxins into the soil and water. The City of Buffalo recently adopted a policy to reduce purchasing of products containing Persistent Bio-Accumulative Toxins, or PBTs. But the decision could put more fiscal strain on a city that’s already in crisis. University at Buffalo Chemistry Professor Joe Gardella helped push for the law. He says a university study convinced the city it could both be fiscally and environmentally responsible.
“It doesn’t create additional exprenses, and, in fact, if one takes a long-term view of the fiscal impact, especially on the issue of creating markets for the recyclables that you’re trying to sell, there can be some really solid benefits to this,” said Gardella.
Under the new law, officials can only pay ten percent more for an alternative product. They say other costs will be reduced by eliminating some unneccessary purchases.

Wind turbines can be both a blessing for farmers, as a source of extra income... and annoying to the neighbors. (Photo by Lester Graham)
Wind farms of huge turbines are springing up along coastlines,
windy ridges and blustery farmland. Most of us see them from a distance.

Wind farms of huge turbines are springing up along coast lines, windy ridges and
blustery
farmland. Most of us see them from a distance. The Great Lakes Radio Consortium’s
Chris
Lehman recently visited some of them up close… and has the first of two reports on
wind energy…
If you can imagine the sight… there are 63 wind turbines scattered across the
prairie farmland,
their huge blades sweeping around, capturing energy from the wind. Each turbine is
213 feet
high. You can see them from miles around. But it isn’t until you stand directly
underneath the
80-foot long blades as they rotate in the wind that you begin to appreciate their size…
(sound of wind from underneath turbine)
“This is probably a typical day. They’re probably producing at about 30 percent of
what they are
rated at, and probably on average, for a year, this is what you’d expect.”
Christopher Moore is Director of Development for Navitas Energy. The Minnesota- based
company opened the Mendota Hills Wind Farm in northern Illinois just over a year ago.
Q: “What are some of the highest levels that you’ve reached?”
“Each turbine is capable of producing 800 kw, and there are times when we’ve had the
windfarm
working at about maximum.”
Moore says the Mendota Hills Wind Farm produces enough electricity to power about 15-
thousand homes per year. It’s the first wind farm in the state of Illinois.
Brian Lammers is a Project Manager for Navitas Energy. He says the location is
ideal since it’s
windy here nearly all year long…
“The wind here is more robust in the fall, winter and spring. So we have more
production during
those months than we do during June, July, August.”
Unfortunately, the summer months are the months that most often experience peak
demand for
electricity. Because of that, and because it takes so many windmills to generate
lower amounts of
power, it’s unlikely that current wind energy will completely replace fossil fuel
generated power.
(sound of turbines)
On the flat prairies of Illinois, the giant turbines are the tallest structures for
miles around. You
begin to wonder about things like lightning strikes…
“We might have experienced one or two last year. The turbines are protected from
lightning. The
entire wind farm is grounded, so if there is a strike typically it will just be
grounded down to the
ground grid. There’s typically no long-term damage associated with a lightning
strike. But as you
can imagine, they’re the tallest structures around so there are periodic lightning
strikes.”
Q “What about a tornado? This is tornado country…what would happen if one came
through
here?”
“I don’t know. These turbines are built to withstand everything but a direct strike
from a tornado,
so I think the same thing would happen to a wind turbine that would happen to any
large
structure if they were struck by a tornado. You’d probably have some significant
damage.”
(fade up sound inside turbine)
Inside the turbine, there’s a distinct hum as the blades whirl away at the top of
the hollow shaft.
It’s about ten feet across at the base, and a metal ladder allows anyone brave
enough to climb all
the way to the top.
Despite the hum of the turbine’s blades up close, the sound fades away just a few
dozen feet from
the tower. But noise isn’t much of a concern for this wind farm. It’s in the
middle of a soybean
field and there are no neighbors nearby.
Noise is just one of the aesthetic concerns for neighbors of wind farms. Appearance
is another.
The Mendota Hills turbines are coated with a special paint that appears white in
bright sunshine.
But when the sun’s not out, the turbines appear grey, and seem to blend in with the
cloud-covered
sky.
Dennis Cradduck has 19 of the turbines on his corn and soybean farm. He says the
wind farm
hasn’t been a problem. Of course, he’s getting paid by Navitas for allowing the
turbines on his
land. But he says the wind farm has led to an unexpected benefit: getting to meet
people from
across the country who pull off the highway for a closer look…
“We get people almost on a daily basis that drive by on the interstate and see them,
and stop and
want to look at them, and they’re amazed at them, and most—about 99 percent of them
have been
positive comments. In fact, one fellow from North Carolina stopped the other day
and said ‘I wish
we’d build more of these around the country because we need renewable energy.'”
The prospect of more renewable energy is appealing to most environmentalists. But
some worry
that wind farms can be deadly to birds. A study by the National Wind Coordinating
Committee
found that wind turbines kill an average of two birds per year.
Another concern is that windmills disrupt the scenery. But the only view around
here is farmland
as far as the eye can see. And on this brisk day, it isn’t just corn and soybeans
being harvested: it’s
the power of wind.
