People have been concerned
about farm chemicals getting
into drinking water supplies
for a long time. A recent report
showed that the chemical atrazine
peaks, in many areas, in concentrations
much higher than previously thought.
Julie Grant reports there are
things you can do to protect your
family. But, finding out if you
have a problem is harder:

Bob Denges is worried. His water is discolored. So he’s
called a water purification company to test it.

(sound of running water)

They’re running water in the basement utility sink. It’s kind
of orange-y looking. So, it’s an easy diagnosis: too much
iron.

“You can probably see in the toilet, upstairs just on the first
floor, that there’s some brownish, reddish discoloration
around the toilets.”

That’s not great. But at least you can tell when there’s iron
in the water. You cannot see or taste other water
contaminants such as weed killers like atrazine.

Tom Bruusema is the water filter expert at the National
Sanitation Foundation. They test and certify water filtration
devices. He says the first place you can check is your local
municipality – the folks that monitor water in your area.

“That would be the place to start. They are required, by
federal law, to measure a number of contaminants, produce
an annual report for their consumers.”

But recently an investigative report by the New York Times
revealed water contamination can spike in some places –
and local water officials might not even know about it.

That weed killer – atrazine – is applied on farm fields and, in a
lot of places, you also find a lot of atrazine in the water
during that time.

If you’re looking for it at the right time.

Sometimes it spikes for longer than a month. But some local
water officials only test for atrazine once a month, or only
once a year, and often it’s not during that peak application
season.

So people can’t really find out about atrazine levels for their
drinking water in those places.

Some water systems are spending lots of money to treat
drinking water to get atrazine levels down to what the federal
government considers safe levels.

But that might not be enough, according to some of the new
scientific evidence about atrazine.

Five studies published in peer-reviewed journals recently
have found evidence suggesting that small amounts of
atrazine in drinking water causes health problems. Even at
levels considered safe by federal standards, atrazine might
be associated with birth defects. Things like low birth
weights in newborns. Skull and facial malformations and
misshapen limbs.

Forty-three water systems in six states — Illinois, Indiana,
Iowa, Kansas, Mississippi and Ohio — recently sued
atrazine’s manufacturers. They want to force the company
Syngenta and its partner Growmark to pay for removing the
chemical from drinking water.

Steve Tillery is an attorney in the lawsuit.

“Some of them have gone to the expense to cleaning it
completely out of their water supplies, so that it doesn’t exist
at all. And they should, in our view, be entitled to
reimbursement of expenses for cleaning it completely out of
their water supplies.”

But, some water systems are not cleaning out atrazine
completely. And, as we mentioned, there are times when
some don’t know they exceed the federal safe drinking water
levels.

There is something pretty easy you can do if you’re worried
about your water.

Tom Bruusema of the National Sanitation Foundation says a
simple carbon filter can remove atrazine. Those are the
filters you can attach to the faucet or the pitchers you refill.

“So it’s a good investment. Certainly can help them if they
have those kinds of concerns, and particularly those living in
an area that’s known to have potential contaminants in the
water supply.”

But first people have to be aware of a possible problem.
And, too often, they are not.

Connectedness of Climate and Healthcare

The health care debate is sucking
up most of the energy in Washington.
So it makes sense that the world is
concerned the US might show up at
global climate talks in December empty
handed. Conrad Wilson explains how
the heath care debate is threatening
the chances of a global climate treaty:

European countries, along with China and other big global polluters, are wrestling with
how to deal with global warming. But as the world gears up for the climate change
conference in Copenhagen, Washington is focusing on health care.

The timing of Washington’s health care debate has many countries scratching their heads.
And it has environmentalists and climate folks nervous. All agree health care is
important; but globally, they say, it’s out of step.

And when you ask Americans what the President is working on, few mention climate
change.

Person 1: “Probably health care and fixing the economy.”

Person 2: “On the economy. And fixing the economy. Actually, no, I’ll change that.
Actually, what I think he’s focusing on is the health care issue.”

Person 3: “This week, Afghanistan. Last week, health care. The week before, the
economy.”

Person 4: “He’s focusing on health care primarily, which is very important. But he also
needs to maintain his focus on the economy.”

What’s not being talked about is climate change and the global talks coming up in
Copenhagen.

Dan Esty is a professor of Environmental Law & Policy at Yale University. He also has
experience as a climate negotiator. Esty predicts the health care debate will continue
through the end of the year.

“I think it’s going to be very difficult, given the political effort that’s going to be required
to achieve success on health care, to imagine that climate change can be taken on during
the same time period.”

Esty says there’s only so much President Obama and members of Congress can take on at
once. Climate change and health care are two major issues that can’t be resolved
overnight.

As time wears on, the talks are shaping up for an outcome that looks more like the failed
Kyoto climate agreement from a decate ago. After Kyoto, Congress refused to join the
rest of th eworld in capping carbon emissions. Esty fears that could happen again.

“The health care debate, at the present moment, is occupying all the political oxygen in
Washington and that means there’s really nothing left with which to drive forward the
response to climate change. And, as a result, our negotiator will go to Copenhagen
without any real game plan in place for how the United States is going to step up and be a
constructive part of the response of the build up of green house gases in the atmosphere.”

A lot of people say the US needs to pass a climate change law before going to
Copenhagen. But others say maybe not. They argue it’s not a bad idea for the US to go
into global climate talks without a law because it could allow negotiators to be more
flexible.

Regardless of how it’s done, cutting greenhouse gases is now more pressing than ever
before. With Washington paralyzed by the health care debate, the timing is just bad for
climate change.

“If there were ever a time. You can say that about health care and about climate policy.”

That’s energy analyst Randy Udall. He says President Obama has a lot of his plate and
should be ready to compromise.

“Obama’s not going to get nearly as much as many of us had hoped for in terms of health
care reform. And he’s not going to get nearly as much as many of us had hoped for in
terms of energy policy. He will get something. But it not going to be a half a loaf, it’ll be
a quarter of a loaf.”

Pundits say President Obama is putting all his political chips in the fight for health care.
And, if he loses, he’ll have almost nothing left to spend on climate 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:

Transcript

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.

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:

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.

Tomato Blight Spreading

If you’ve been waiting all season
for that quintessential taste of
summer – a juicy, ripe tomato from
the garden – you might be disappointed.
This year a tomato blight has swept
across the Northeast and is moving
into Midwestern gardens and farms.
Julie Grant reports:

Walk around this outdoor farm market in Cleveland and just say the words ‘tomato blight’ – nearly anyone in earshot has a story to tell.

Susan Myers says her home garden has given over to what she thinks is late blight.

“But it’s pretty serious. I mean, it’s like wiping out everything. I have lots of tomatoes and all the leaves are dropping. I’ve never, ever had that before.”

It doesn’t look like the farmers here are having trouble with tomato blight. Most tables are piled high with bright reds and yellows.

Skip Conant has a beautiful display of heirloom tomatoes – but he’s not sure how many more weeks he’ll have fruit to offer.

Conant: “We definitely have tomato blight. It’s been a cool, wet spring, so, yeah. There’s a fair amount tomato blight.”

Grant: “What does it look like?”

Conant: “You’ll see a yellowing and curling on the leaves and then the stem will turn brown. The plant will become a very brown. Die from basically the inside out or the bottom up.”

It’s hard to tell yet if these Midwestern growers are starting to see the same blight that decimated the northeast tomatoes.

Bill Fry is a plant pathologist at Cornell University. He’s studied late blight for 35 years. Fry says it looks like irregular shaped black spots, and can appear on the leaves or the fruit. It can destroy an entire crop in just a few days.

This is the same blight responsible for the Irish potato famine in the mid-19 century. Growers have seen late blight since then. But Fry says, not at these epidemic proportions.

“The fact that it’s just everywhere is, I think, is the major difference from previous years.”

This wasn’t the first cool, wet spring on record. So, why has the blight so bad this year?

It’s kind of ironic. Fry and his colleagues have been studying the problem and think it’s probably because so many people are gardening. Millions more than just last year. And lots of those people bought tomato plants at stores like Home Depot, Kmart, Lowe’s and Wal-Mart.

“Infected plants were sold throughout the northeast in the box stores. They were transplanted to home gardens and from there the pathogen disbursed to other home gardens, to conventional and organic farms.”

Fry says you might not even notice at the supermarket. Commercial tomato growers spray lots of fungicide to keep away the blight. But organic tomatoes are getting harder to find.

But chefs and tomato lovers who’ve waited all season for those locally-grown heirloom – and especially organic – tomatoes aren’t finding what they want in markets in the northeast.

Back at the Cleveland market, chef and restaurant owner Karen Small has been waiting for tomato season – and it finally hit. She depends on this market for her produce and stops at just about every stand.

But as Small hears farmer after farmer describe what they think is late blight – she’s worried about the weeks to come.

“We’re accustomed to having tomatoes well into September, and maybe that’s not going to happen this year.”

Small plans to go home and rip out the tomato plants in her home garden – after hearing late blight described so many times, she’s pretty sure her tomatoes are infected.

But an ongoing study indicates the

Many of us have engineered physical activity out of our lives. We sit in front of the computer, we sit and drive everywhere. We don’t move much.

That’s what Steven Blair says. Blair is a professor of Public Health at the University of South Carolina. And he says, more than anything else, America’s physical in-activity will cause this century’s biggest public health problems.

“You want to stay out of the nursing home, the best insurance you can take out is regular physical activity program – three ten minute walks five days week. I’m not talking about training for the Ironman triathlon or a marathon.”

He says we need to re-engineer physical activity back into our lives. And part of that includes making communities super walk-able and bike-able.

A new report in the journal Nature Reviews
Cancer looks at cancer in wildlife. Mark
Brush reports, the disease in animals is
sometimes caused by pollution:

The authors of this paper looked at a lot of research on cancer in wild animals. Some of these studies linked the cancer cases to pollution.

Beluga Whales along the Canadian Atlantic coast developed tumors after they came in contact with chemicals from aluminum smelters. And some fish and clam species have developed cancers after being exposed to pollution.

Denise McAloose is a veterinarian with the Wildlife Conservation Society. She’s the lead author of the paper.

“People should care about cancer in wildlife because, especially in those cancers that are driven by environmental factors, those environmental factors affect not only the animals, but people as well.”

For example, the people who worked in those aluminum smelters also had higher rates of cancer.

She says more research into the link between pollution and cancer in animals needs to be done. Because looking at how the disease affects wildlife might help us treat or prevent cancer in people.

Styrene Industry Sues Over Cancer Listing

Transcript

The styrene industry is suing to stop environmental officials from saying styrene could cause cancer and birth defects. Lester Graham reports:

Styrene is used in all kinds of products – containers like coffee cups, egg cartons, in construction, in cars.

The state of California wants to add it to a list of cancer-causing materials. The International Agency for Research on Cancer found styrene is “possibly carcinogenic to humans.”

Joe Walker is a spokesman for the Styrene Information and Research Center.

“Styrene is not a carginogen. Any listing that would categorize it as such basically would be illegal and would be erroneous and would have the potential of alarming the public unnecessarily about products that are made from styrene.”

If the court does allow California to put styrene on its cancer list, the styrene industry has a year to prove it doesn’t belong on that list.

Transcript

So many of us have an old bike collecting
dust in the garage. More often than not,
they end up in the garbage. But, as Karen
Kelly reports, one group has found a unique
way to recycle them:

(sound of banging)

“That’s a sweet ride!”

A volunteer drops a bike into a pile at the back of a huge shipping container in Ottawa, Canada.
The bikes are stacked one on top of the other.

(sound of tools)

Just outside, a mechanic is stripping the bikes down to make them as compact as possible.

“If it has a kickstand, we have to remove it. We take the pedals off and turn the handlebars.”

In a few hours, this cargo container will be jammed with hundreds of donated bicycles, bike parts, and backpacks.

The gear is collected by a group called Bicycles for Humanity.
They have 20 chapters, most of them in North America.

Each chapter raises a couple of thousand dollars to buy a shipping container.
They pack it full of donated gear, and send it off to a community in Namibia, Africa. The shipping cost – another several thousand dollars – is also raised by the group.

A volunteer group there turns the container itself into a locally-run bike shop that provides jobs and transportation.

Some of the bikes are donated to health care workers who use them to pull patients on a stretcher.

Others are piled high with stacks of food and household items that defy gravity.

Martin Sullivan points to some of the pictures on display.

“These are the bakers who are able to sell their bread. And also wood, you can stack wood. It’s just amazing what they do, how they make use of these bikes that we take for granted. We throw them out, and they can do so much with them.”

(sound of traffic)

In Namibia, cars – and even bicycles – are scarce. Sullivan says these bikes make life easier for people who are used to walking miles to get to school, work, or to find the basic necessities.

Seb Oran is the co-founder of Bicycles for Humanity in Ottawa.

This is the fourth container of bikes that she’s sent to Africa.
Each one supports a local community group.
Sometimes its a hospital, sometimes an orphanage, sometimes a women’s empowerment group.
She remembers one run by former prostitutes.

“Six of them became bicycle mechanics now. And now, they don’t have to sell their bodies to put food on their plate.”

But there are some challenges.

Michael Linke runs the Bicycle Empowerment Network.
He helps the Nambians set up the bicycle shops.

“Because this is the first time a lot of these people have had formal ongoing work, it’s often difficult to get people to understand a long-term ongoing business.”

But with some mentoring, they’ve been able to make it work.
There are now 13 successful projects, with more containers filled with bikes on the way.

The group estimates that these bikes will last another 20 or 30 years in Africa. They might be junk to us, but in Namibia, they’re a precious resource.

A new study in the Journal of

link between some food preservatives
and an increased risk of death from
Alzheimer’s, Parkinson’s and diabetes.
Rebecca Williams has more:

Nitrates and nitrites are found in a lot of foods we eat: bacon, hot dogs, and even cheese and beer.

The chemicals aren’t there naturally – they’re added as preservatives. And they’re also used in fertilizers.

Dr. Suzanne de la Monte is the study’s lead author.

She says they found a strong connection between higher death rates from Alzheimer’s, Parkinson’s and diabetes and the increases in our exposures to these chemicals in our food and water since the late 1960s.

“What we’ve identified says this is certainly something I would consider very very important. Are there other things? Probably.”

She says people could be genetically predisposed to these diseases.

But she says long term exposure to nitrates and nitrites could also be playing a role in two ways: whether we get these diseases and how severe they might end up being.
