The US Environmental Protection Agency
is wrapping up a 60-day initiative
looking at toxic air pollution around
schools. They’re looking to gauge the
health effects linked to pollution exposure.
Many of the schools were chosen based
on how close they were to heavy industry.

Transcript

It’s pretty much a given: put a school near heavy industry and an interstate, and those
kids are going to be breathing polluted air. What the EPA didn’t know was just how
polluted it would be. So the agency in August put air samplers outside of 63 schools in
22 states. One of those schools is Lewis Elementary in Birmingham, Alabama.

(sound of calling out names for carpool)

As he does every day, Richard Gooden is waiting in the carpool line to pick up his
granddaughter, who attends pre-K at the school. Not far away, near the basketball
court, there’s an air pollution monitor. Gooden, for one, was glad it was there. Living
up the hill from the American Cast Iron Pipe Company, he’s seen thick layers of dust
settle on his windows.

“I got a little white house with vinyl siding, and you can’t tell there’s vinyl hardly
because of the dirt coming from that pipe shop.”

Gooden has lived in that house for 43 years. His granddaughter spends most days
there, and he worries about her health and his own.

“I had a triple heart bypass a while back. I’m just wondering is that air completely
clean to breathe.”

The EPA plans to have some answers. In Birmingham, the Jefferson County Health
Department is collecting the data on the EPA’s behalf. Corey Masuca is the county’s
senior air pollution control engineer. He says they’re screening for about 100 different
pollutants.

“We looked for them, then, we found them.”

So far, he says, only three of those – benzene, manganese and acrolein – were found
at high levels. Most concerning, acrolein levels were more than 100 times higher than
what the government considers safe. Where does it come from?

“Pretty much any type of combustion source – whether it’s combustion coal, or
fuels from a plant, or fuel from a car. It even emanates from cigarette smoke, so it’s
fairly ubiquitous.”

But ubiquitous doesn’t mean safe. In fact, excess exposure to manganese can cause
brain damage. Acrolein can damage the lungs, and benzene is a carcinogen.

Masuca says the findings aren’t a major cause for concern. But Janice Nolen,
Assistant Vice-President for Policy and Advocacy at the American Lung Association,
disagrees.

“The fact that it’s in lots of places doesn’t mean it is not a big problem. It means
that we have a lot of things that we need to clean up.”

And when it comes to schools, she says, industrial pollution isn’t the whole picture.
Diesel buses drive right up to the school doors every day. Inside schools, poor
ventilation and even things like some glues can lead to health problems.

Yet there are definite links between these air toxins and heavy industry. So Masuca, of
the Jefferson County Health Department, says just knowing what’s out there is a huge
first step. Next they’ll come up with ways to reduce exposure. Things like having kids
stay indoors during recess on days when pollution levels seem to be highest.

Janice Nolen of the American Lung Association hopes monitoring will lead to stricter
controls on nearby industry. And maybe spark even a little bit of self-regulation.

“Letting people know about what’s in the air often raises public awareness and
causes industry to rethink what they’re doing and come up with less toxic ways to
produce their products.”

She says this research can galvanize communities into action. Most of the parents I
spoke with at Lewis Elementary didn’t know a thing about the EPA’s monitoring
program. But perhaps once the EPA gathers long-term data on schools across the
country in the months to come, that will change.

Low in the Vitamin D Department

How much sun you need to get enough Vitamin D depends on where you live, the time of year, how much skin you're exposing - and even the color of your skin. (Photo source: Kallerna at Wikimedia Commons)

According to two recent studies,
most kids in this country aren’t
getting enough Vitamin D. Scientists
say a lot of adults are low in the
vitamin, too. Ann Dornfeld looks
at whether the solution is as simple
as spending more time in the sun:

According to two recent studies, most kids in this country
aren’t getting enough Vitamin D. Scientists say a lot of
adults are low in the vitamin, too. Ann Dornfeld looks at
whether the solution is as simple as spending more time in
the sun:

(sound of kids building sandcastles on the beach)

If you’ve been to the beach this summer, or anywhere
outdoors, you probably slathered on the obligatory
sunblock. If you were extra-careful, you wore a wide-
brimmed hat, or made sure your kids wore t-shirts in the
water instead of a skimpy suit.

Thing is, the solar radiation you work so hard to avoid is
also kind of healthy. That’s because it creates Vitamin D
through a chemical reaction in your skin.

“Vitamin D is essential.”

Susan Ott is a professor of medicine at the University of
Washington.

“It’s actually a steroid hormone that helps you absorb
calcium from your diet. And it works in your intestines so
the calcium can get into your system and become
available to the bones.”

Ott specializes in bone diseases like osteoporosis and
osteomalacia – both diseases that Vitamin D helps
prevent.

When you slather on sunblock, you’re also blocking the
creation of Vitamin D.

Before you run outside to soak up the last few rays of
summer unprotected, there’s a catch. Ott says no one
knows how much sun you need to get enough Vitamin D.
It depends on where you live, the time of year, how much
skin you’re exposing – and even the color of your skin.

“People with dark skin do not make as much Vitamin D
with the same amount of sunlight exposure – they need to
be out in the sunlight longer to get the same amount of
Vitamin D as a fair person.”

Scientists don’t have a way to recommend how much sun
you need to get enough D.

Kim Nowak-Cooperman is a nutritionist at Seattle
Children’s Hospital. She says a recent study looked at
people who live in Honolulu.

“They looked at 93 people who got three or more hours of
sun every day for five days a week. And they actually
found that half of those people were Vitamin D insufficient,
when you would think that they would be very, very high in
Vitamin D.”

Getting your Vitamin D from food can also be hard. It’s
naturally abundant only in oily fish like sardines, salmon
and mackerel. Since the 1930s, Vitamin D has been
added to milk to prevent the bone-softening disease
rickets in children. Now rickets is making a comeback.

Nowak-Cooperman says that’s because most kids don’t
drink enough milk to get the recommended daily
allowance of Vitamin D. And even that recommendation
might not even be enough.

“Originally that number was derived from the amount of
Vitamin D that would prevent rickets. We are now seeing
that Vitamin D has a more important role and that the
insufficiency of Vitamin D can be implicated in other
disease processes.”

Studies show Vitamin D might prevent everything from
rheumatoid arthritis to diabetes to tuberculosis. So the
American Academy of Pediatrics now recommends kids
get twice the US RDA for Vitamin D. That means 400 IU from either four glasses of milk or a
supplement.

Professor Susan Ott says adults should take a
supplement, too. She recommends 800 to 1000 IU. Any more than that, she says, and you risk
absorbing too much calcium.

“I think right now there’s a fad and people are taking too
much. I just went to the drugstore the other day and I saw
pills that were 5000 units. That’s enough to last you a
week! And I have patients that are taking that every day.
I’m worried they’re gonna get kidney stones.”

Ott says there’s also a trend for people to get blood tests
to determine whether they’re getting enough Vitamin D.
She says unless you’re elderly or have other serious
health problems, it probably isn’t necessary.

So what should you do? Ott says just pop that daily
supplement – 400 IU for kids, 800 for adults – and
keep slathering on the sunblock.

Not All Sunscreens Created Equal

The Environmental Working Group is critical of the Food and Drug Administration for not requiring sunscreens to filter out UVA rays (Photo courtesy of the National Cancer Institute)

Labor Day weekend means backyard
grilling, maybe some time at the
beach. The last holiday of summer
usually includes a lot of time outside.
Lester Graham reports sunscreen
seems like a good idea, but there’s
some controversy about what works:

Transcript

The Environmental Working Group issued a report saying not all sunscreens are equal. The group is critical of the Food and Drug Administration for not requiring sunscreens to filter out one kind of solar radiation.

“There currently are no requirements for UVA filters in sunscreens. And they’ve been working on sunscreen standards since 1978.”

David Andrews is a senior scientist with the group. He’s says with a gap in FDA regulation, the industry is making unverified statements about how well sunscreens protect.

“So these are claims that are very misleading to the consumer and it makes it hard for everyone to get adequate protection.”

The Personal Care Products Council is a trade group for sunscreen makers. It says the Environmental Working Group’s report is – quote – “unscientific and unsubstantiated.”

Bottom line: look for a sunscreen that does protect you from both UVB and UVA rays, reapply often, and stay out of the sun as much as possible.

Interview: Nature Improves Productivity

Not everyone can get out and walk along the Lake Superior coastline everyday, but researchers say any walk in a natural setting will help. They count an increase in productivity among the benefits. (Photo courtesy of Dave Hansen.)

You’ve probably heard about studies that show enjoying nature can reduce stress. Well, a new study published in the journal Psychological Science shows a walk in nature can also help you focus better. It can improve your memory and attention. Lester Graham asked one of the researchers, Marc Berman from the University of Michigan, if he was up for a walk:

Driving Down Road Noise

Whizzing tires, whining engines and booming car
stereos are just about everywhere. Those sounds are a
form of pollution, and can affect the way we feel. Kyle
Norris has this story:

The engineers at Chrysler are hard-core about noise.

Right now they’re inside a high-tech studio.
And there’s a car on rollers.
The engineers are trying to pinpoint the noises that a driver would hear.

Inside the cabin it’s pretty quiet (quiet sound inside cabin).
But outside, well… Engineer Taner Onsay explains.

(yelling over whirr of tires) “This is how it sounds outside. See, I cannot
communicate with you, with this sound. Inside this would be totally unacceptable.”

Cars that are quiet are the inside are a huge selling point in the auto biz.
But what about the sounds that a vehicle puts into the world?

Like road noise.
What are people doing about that?

Not a whole lot.

Story goes, there used to be a federal office that dealt with noise.
It was the EPA’s Office of Noise Abatement and Control.

But President Reagan shut that baby down in 1982.
Basically to save on cash.
The idea was that state and local governments could deal with noise.

The noise office did a lot of good things just to help protect our ears.
It had noise standards and regulations – on the books.
And the office was just a really good resource for state and local organizations, and also for people who were just having problems with road noise.

But since it’s been gone…

“Well a lot of the local noise-control programs at the city and county level just dried up
and blew away. It’s hurt the noise program tremendously throughout country.”

That’s Bill Bowlby.
He’s president of an engineering company that consults about road noise.
He’s also worked for state departments of transportation and for the Federal Highway
Administration.

He says that state departments of transportation are concerned about road noise.
And that they’re thinking about things like quieter tires and quieter pavements.
And about not building residential areas near highways.

But states are only required to do so much about road noise.

For example, when states are widening or building highways and using federal money –
which they almost always are – they’re required to study road noise and obey certain
standards.

But when it comes to road noise coming from an existing highway, it’s totally voluntary if
a state wants to deal with it.

So you get a range of how different states deal with it, which they call retrofitting.

Bill Bowlby that says although some states take the issue very seriously…

“…other states have had little interest in idea of retrofits usually because they’re looking
to spend their limited amount of money on highway related projects.”

And the kicker about road noise is that it can seriously, seriously affect people.
For people who live near noisy roads, it can make their lives miserable.
Plus it can make it hard to concentrate as a driver.
And to hear the vehicles around you, like motorcycles and other sounds, like sirens.

Dennis Weidemann is a guy who’s thought a lot about all this.
He wrote his thesis about road-noise.

He says that road noise isn’t dramatic or flashy.
So it doesn’t grab our attention.
And road noise does not have a villain, so we’re all responsible.

Weidemann says it can seem hopeless to people.

“They know they don’t like it but they don’t know how it effects them. And if you don’t
know that, you just get the impression, well, it just bothers me, I’m weird, I’ll let it go.”

Noise experts say we need to re-open the federal noise office.
Or something like it.
And we’ve got to figure-out how to make things quieter.

This is starting to become a hot topic in the pavement industry, where different
businesses are trying to one-up their competitors by making the quietest pavement.

But for car companies there’s really no incentive to make cars that are quieter on the outside.
And right now there are no regulations of how quiet a car needs to be when it comes off
the assembly line.

Although that’s not the case in Europe,
where vehicle noise regulations are much more strict.
And where the whole subject of road noise is taken a lot more seriously.

Point: Agreements Will Help Protect Great Lakes

The proposed Annex 2001 agreement is the subject of lively debate as to whether it will help or hinder the conservation of the Great Lakes (Photo by Jeremy Lounds)

In 1998, an Ontario company wanted to sell Lake Superior water overseas. Their proposal raised fears that Great Lakes water could be diverted with little oversight. Now, officials from the eight states and two provinces in the region have come up with two proposed agreements that would regulate new water diversion requests. The proposed agreements are known as the Annex 2001 Implementing Agreements. Great Lakes Radio Consortium commentator Cameron Davis says the agreements are a good first step in protecting a cherished resource:

In 1998 an Ontario company wanted to sell Lake Superior water overseas. Their
proposal raised fears that Great Lakes water could be diverted with little oversight.
Now, officials from the eight states and two provinces in the region have come up with
two proposed agreements that would regulate new water diversion requests. The proposed
agreements are known as the Annex 2001 Implementing Agreements. Great Lakes Radio Consortium
commentator Cameron Davis says the agreements are a good first step in protecting a cherished
resource:

When I was growing up, my family and I used to go to the beach every Sunday. As I stood
looking out over Lake Michigan, I was awed at how it seemed to go on forever. Today I know
better. The Great Lakes are a gift left from the glaciers thousands of years ago. That’s
because less than 1% of Great Lakes water is renewed every year from rainfall, snowmelt,
and groundwater recharge.

Two proposed agreements by the states and provinces would make diversions of Great Lakes water
to places outside of the Great Lakes a virtual impossibility.

The agreements look to be a vast improvement over current laws. First, federal law in the U.S.
allows a diversion only if every Great Lakes Governor approves. That seems like a tough standard
to meet, but in fact, it’s already allowed two diversions of Great Lakes water to take place. In
the 1990’s, diversions were approved to Pleasant Prairie in Wisconsin and another one to Akron,
Ohio. The water was used for municipal supplies.

Second, the proposed agreements are an improvement over the Boundary Waters Treaty – a pact
signed between the U.S. and Canada almost 100 years ago. The treaty doesn’t cover one very
important Great Lake: Lake Michigan. Because Lake Michigan is solely within the U.S. and not
shared with Canada, the treaty leaves the lake unprotected. This is a problem because Lake
Michigan is directly connected to Lake Huron. So water diverted out of Lake Michigan means
water diverted out of Lake Huron.

The agreements are a good first step, but they need to be stronger. For example, they require
regional approval for diversions of water that go outside of the basin of more than one million
gallons per day, but they don’t require regional approval for withdrawals of up to 5 million
gallons per day that stay in the Great Lakes. In addition, the draft agreements need to do a
better job at requiring water conservation before potential water withdrawals can be considered.

We have a choice. We can be against the agreements and keep the status quo or work to make
them even stronger. We need to work to protect our region’s water so that our kids can continue
to look out over the Great Lakes and see them for what they are: vast, magnificent, but fragile
natural treasures.

The Foibles of Suburban Lawn Care

Although a well-manicured lawn offers certain benefits... not everyone thinks it's worth the effort. (Photo by Ed Herrmann)

One of the great rituals in suburban America is mowing the lawn. A
manicured lawn seems to say that the house is well cared for, that it belongs
to the neighborhood. Great Lakes Radio Consortium commentator Ed
Herrmann wonders whether this obsession with the perfect lawn is worth the
effort:

(sound of evening insects)

It’s a late summer evening and at last I can go outside and enjoy the
sounds of the neighborhood. There’s a little breeze, the air is cooler. The
chorus of insects is soothing, gentle but insistent, an ancient throbbing
resonance. Much better than during the day…

(roar of lawn machines)

Summer days in the suburbs are the time of assault, when people attack their
lawns with powerful weapons from the chemical and manufacturing
industries. Anyone who uses the words “quiet” and “suburbs” in the same
sentence has never been to a suburb, at least not in summer.

It takes a lot of noise to maintain a lawn. Besides the mower, you’ve got edgers, trimmers,
leaf blowers, weed whackers, core aerators, little tractors, big tractors, slitting
machines. I don’t know whatever happened to rakes and hand clippers. One
thing’s for sure. This quest for lawn perfection wouldn’t be possible without
the industrial revolution.

(machines stop)

So where did we get the idea that a house should be surrounded by a field of
uniform grass kept at the same height?

Well, with apologies to the Queen, I’m afraid we must blame the British. It
seems that, along with our language, our imperial ambitions and our
ambivalent morals, America also gets its notion of what a lawn should look
like from the English. Of course, the estates of the English aristocracy were
tended by a staff of gardeners. England also has a milder climate, and the
grass that looks so nice there doesn’t do as well in North America. In the
1930’s the USDA came up with a blend of imported grasses that would
tolerate our climate. Since these grasses are not native, they need help, and
that calls for fertilizers, pesticides and lots of extra water. Since normal
people can’t afford gardeners who trim by hand, that means lawn machines.
American industry to the rescue.

(mower starts up, fades under next sentence)

A quick Google tells me that today we have 40 million lawn mowers in use.
Each emits 11 times the pollution of a new car, and lawn mowers contribute
five percent of the nation’s air pollution. Plus more than 70 million pounds of
pesticides are used each year and over half of our residential water is used
for landscaping. Don’t you love those automatic sprinklers that come on in the
rain? Add to that all the time that people spend mowing and edging. Of
course the two billion dollar lawn care industry is thrilled about all this
enthusiasm, but I gotta ask, “Is it worth it?”

Call me old fashioned, but I actually prefer the looks of a meadow with mixed
wildflowers and grasses to the lawn that looks like a pool table. My own lawn
is somewhere between. It’s mowed, but it’s what you might call multicultural.

There are at least five different kinds of grass with different colors and
thicknesses, plus clover, dandelions, mushrooms, a few pinecones, and a
rabbit hole or two. There’s also some kind of nasty weed with thorns, but even
that has nice purple flowers if it gets big enough.

Clover, by the way, used to be added to grass seed because it adds nitrogen to
the soil. Now we just buy a bag of nitrogen fertilizer, so who needs clover?
And what’s wrong with
dandelions? You can eat them, some people even make wine out of them,
they have happy yellow flowers; yet to most people they indicate your yard is
out of control. So I’m down on my hands and knees pulling dandelions. I’m
not sure why, but I hope it keeps the neighbors happy.

One thing I won’t give in to, though, is the chemical spraying trucks, painted
green of course, that roll through the neighborhood.

I can only hold my breath. (sound of trucks and mowers) Try not to listen. And
wait for the evening. (evening insects)

(air conditioner starts up)

Although, with all these air conditioners, even the night’s not too quiet.

But that’s another story.

Winter: An Old Friend Returned

As the heart of winter approaches, it’s tempting to withdraw from the outdoor world and wait till spring. But Great Lakes Radio Consortium commentator Tom Springer thinks the forgotten benefits of winter far outweigh the hardships:

Transcript

As the heart of winter approaches, it’s tempting to withdraw from the outdoor world and wait till
spring. But as Great Lakes Radio Consortium commentator Tom Springer thinks, the forgotten
benefits of winter far outweigh the hardships.

Outside my window there’s an old sugar maple, grey and bare against the late autumn sky. I’ve
raked up most of its leaves and spread them as mulch on my vegetable garden. It seems like the
tree and me have nothing better to do than wait for spring.

But for a tree, the real work of winter has just begun. To prepare for frigid weather, trees undergo
a process known as hardening off. Their sap withdraws from the twigs and branches and returns
to the roots. And the tree’s roots will continue to grow until the ground freezes solid.

When it comes to surviving winter, I think trees have the right idea. It’s in their nature to slow
down and focus on interior growth. Unfortunately, most of us don’t do that. Instead of adapting to
winter, we try to escape it. We dash from our heated house into a semi-heated garage. We drive in
heated cars – which often have heated seats and even heated steering wheels – and we work in a
heated … Well, you get the idea.

But what would happen if we tried harder to accept winter on its own terms? Might we be happier
and healthier?

Researchers say that people can get surprisingly acclimatized to winter weather. As our bodies
get accustomed to cold, we shiver less and our skin retains more heat. In Australia, scientists have
studied aborigines who sleep outside naked in cold weather. They don’t get hypothermia. In
Japan, shellfish divers have been known to spend hours in the ice-cold ocean, wearing nothing
more than a cotton swimsuit.

Spending more time outside in winter can even make you happier. That’s good news for the 10
million Americans who suffer from Seasonal Affective Disorder. SAD is a form of depression
that’s triggered by the short winter days. Some people take anti-depressants to fight SAD. Yet
researchers find that many people can overcome it without using pills. They just need to get
outdoors and absorb some authentic daylight.

Do you suppose Mother Nature is trying to tell us something? For 50,000 years of human
history, winter was a time of rest and rejuvenation woven between the cycle of seasons. And I
doubt that 75 years of electric indoor heat has changed that. For instance, our bodies still crave
good food in winter – not just fudge and party mix, but homemade soup or a juicy pot roast. And
there’s still something about the solemn purity of winter that calls us to focus inward. To boost
the spirits, there’s nothing like a quiet walk on a snowy Sunday afternoon. It’s also the best time
to read the uplifting books that have languished on the nightstand since summer.

This is, without question, the most trying of seasons. It gets depressingly dark by 6 o’clock, and
the wind howls at the door like a hungry wolf. But the frozen solitude of winter is not a thing to
be feared. Winter is simply an old friend returned, who waits in unspoken silence to wish us well.
