Congress might make our federal
chemical laws tougher. Rebecca
Williams has more:

There are 80,000 chemicals on the market. But the Environmental Protection Agency has only tested 200 of them for safety to humans – and banned only 5 of the toxic chemicals.

Senator Frank Lautenberg is a Democrat from New Jersey. During a recent hearing, he said the EPA is doing what it can. But its power is limited by the nation’s outdated chemical laws.

“They cannot protect our children with one hand tied behind their back. That’s why I’ll soon introduce a bill that will overhaul our nation’s chemical laws.”

The bill will likely require companies to prove a chemical is safe before manufacturing it or using it. Right now, it’s up to the government to prove a chemical is harming people or the environment before it’s banned.

Some Conservatives in Congress are opposed to this idea. They say this kind of bill would kill industry innovation.

There are proposals to drill for oil
and gas very close to the site of a
nuclear explosion. The device was
exploded underground in western Colorado
40 years ago this month. Natural gas
from wells near the site could be
distributed throughout the U.S. Some
experts are concerned the natural gas
could be radioactive. Conrad Wilson
reports regulators could allow drilling
closer to the blast site in the next
couple of years:

On September 10, 1969 the Atomic Energy Commission detonated a 40-kiloton
nuclear bomb a mile and a half under ground. It was called Project Rulison. The
bomb was three times the size of the one dropped on Hiroshima.

The idea was to find peaceful uses for nuclear weapons. The federal government
hoped that nukes could be used to free up pockets of gas trapped below.

(sound of video)

The nuke did free up gas.

The government tested the gas by flaring it – burning it in the open – over the next
year. They discovered the natural gas was radioactive.

Marian Wells is a long time resident of Rulison. Her parent’s home was close to
the detonation site and the gas flares. Both of her parents died of cancer. So did
many of her neighbors.

She spoke before the Colorado Oil and Gas Conservation Commission.

“My parents were given no notice that you were flaring contaminated gas. And
yet both my parents died of cancer. Cancer is prevalent in this area. And yes, no
one has studied those cause and effect. You don’t really care about us.”

There’s been no government studies connecting cancer and the Rulison blast,
but the community remains fearful and suspicious.

Gas drilling is allowed as close as three miles of the blast site. That natural gas
is piped around the country.

Now some companies say they want to drill for natural gas within a half mile of
ground zero.

The Department of Energy maintains that, for the most part, the gas near the
blast site is safe, but there’s some uncertainly.

Jack Craig heads up the Rulison site for the Department of Energy. Craig says
drilling closer to the nuclear blast site should move forward slowly.

“What we’re saying is do it in a sequential manor. So that you come in slowly
testing the wells as you go in for contaminants – specifically tritium – and, if you
don’t find anything, move in closer.”

Tritium is a radioactive substance produced by the blast. Breathing tritium can
cause cancer.

Chris Canfield works on environmental protection for the state oil and gas
commission. He heads up an annual audit on the Rulison site.

Canfield: “Simply put, everything that’s coming out of the ground is being
sampled, being analyzed.”

Wilson: “If someone were to come to you and say they want to drill within the
half mile of the Rulison blast site, would you say that’s safe?”

Canfield: “I wouldn’t really know at this time.”

Canfield says that the state would require a special hearing before it would
approve any drilling permits any closer.

Oil and gas commissioner Jim Martin says there are still too many unanswered
questions to allow drilling that close to the blast site.

“There are significant information gaps and that makes is very difficult to really
understand the risks either to the workers or to the public who live within some
distance of the drill site.”

Martin says he understands why people are skeptical. He says the United States
has made a lot of mistakes with radioactive materials. Navajo uranium miners
got cancer because of radio exposure. People downwind of above ground
detonations suffered. Martin says skepticism is warranted.

“So it’s not unreasonable to ask some pretty tough questions of the federal
government before we go further into that half mile perimeter and produce more
gas.”

Gas that could be burned to heat homes across the U.S.

Could Humans Get Chronic Wasting Disease?

A disease that infects deer and elk has been alarming wildlife officials and hunters for years. But now it seems the disease could be more dangerous than previously thought. The Great Lakes Radio Consortium’s Christina Shockley reports:

A disease that infects deer and elk has been alarming wildlife officials
and hunters for years, but now it seems the disease could be more
dangerous than previously thought. The Great Lakes Radio Consortium’s
Christina Shockley reports:


Chronic Wasting Disease, or CWD, affects the brain tissue of deer and
elk. Sponge-like holes form in the brains of sick animals. The deer
begin to waste away, become weak, and then die.


Since CWD was discovered in Colorado nearly forty years ago, wild deer
in nine other states have tested positive for the disease. Little is known
about CWD – including how to stop it.


What scientists do know is that the infectious proteins-called prions –
thought to cause CWD are found in the brain and spinal cord areas of
infected animals, but officials still don’t have the answer to the big
question.


Judd Aiken is a professor of Animal Health and Biomedical Sciences at
the University of Wisconsin.


“The ultimate question is whether venison from infected animals, CWD infected
deer, poses a risk to humans. Clearly the first question that needed to be
asked and addressed was whether there was infectivity in muscle.”


Recent findings say there is.


Researchers at the University of Kentucky injected muscle from an
infected deer into the brains of genetically altered mice. The mice
displayed signs of CWD. This is the first time the infectious proteins
blamed for CWD have been found in deer meat.


The finding raises questions about whether eating venison is safe.
Researchers including Aiken say the study is important, but has limits.
For example, he says it doesn’t replicate what would happen in real life.
Plus, he says it’s probably unlikely humans can even get CWD. He says
studies suggest it’s difficult for the disease to jump to other species. Still,
he urges caution. Hunters should get the meat tested before they eat deer
from an area where CWD has been found.


“I, in no way, can advocate the consumption of infected deer, and indeed,
I would suggest due to the limitations of the CW tests, I don’t advocate
the consumption of deer obtained from a CWD endemic area.”


Even if the test comes back negative, Aiken says a negative result isn’t
always accurate, and infected animals in the beginning stages of the
disease can look and act normal.


(Sound of sporting goods store)


John White is a deer hunter from Sheboygan, Wisconsin. He’s in the
hunting section of a nearby sporting goods store. White isn’t too
concerned about Chronic Wasting Disease.


“Not a whole lot of people are worried about it. I mean, when it first
came out, some people were a little leery about it and didn’t want to hunt
that year, but they kinda got over it. I’m not really worried about it being
in the meat at all, because by the time the test comes back I’ll probably
have the deer eaten already and then it’s already too late.”


State wildlife officials say… that’s not a good idea. They recommend that
if you hunt deer in areas where the disease has been found, get the deer
tested before eating it. That message hasn’t changed… since learning the
prions could be in the meat. Some argue… it should change.


John Stauber is with a government watchdog group in Wisconsin, and
is co-author of “Mad Cow USA: Could the Nightmare Happen Here?”
He says officials are keeping quiet about the risk of CWD so they don’t
lose revenue from hunting licenses.


A large portion of state conservation agency budgets are dependent on
fees from hunting licenses. He says all deer that die should be tested for
the disease. Stauber also says CWD is a major human health concern.


“The biggest risk might not be the people who would die from
eating venison, but rather, the people who would die from the
contamination of the blood supply. This is a problem that would unfold
not in days or months or years, but even over decades.”


Stauber says it’s just a matter of time before Chronic Wasting Disease
spreads to people… he says some might even have the disease already,
and not know it.


But researchers like Judd Aiken from the University of Wisconsin say
people shouldn’t over-react.


“People should be concerned, but I don’t want people to panic, either. If
you think you may have consumed venison from infected animals, I don’t
think it’s likely that you’ll ever develop a human prion disease.”


But, Aiken says there’s too much we don’t know about the disease, and
since studies can take years to complete, we might be in the dark for a
while longer.

Cosmetics Companies to Phase Out Phthalates

Three major cosmetics companies have announced they’ll stop using certain chemicals that have been linked to health concerns. The Great Lakes Radio Consortium’s Erin Toner reports:

Transcript

Three major cosmetics companies have announced they’ll stop using certain chemicals that have been linked to liver and kidney damage, and reproductive system problems. The Great Lakes Radio Consortium’s Erin Toner reports:


L’Oréal, Revlon and Unilever say they’ll comply with a European Union policy that requires cosmetics companies to stop using chemicals that are suspected of causing cancer, birth defects or impaired fertility. Those banned chemicals include phthalates, which are used in some hair and nail products and fragrances. Bryony Schwan is with The Breast Cancer Fund, the group leading the Campaign for Safe Cosmetics. She says phthalates are just the first step.


“There are a lot of chemicals in cosmetics that are potentially dangerous. We have a lot of chemicals that have not been tested. We have other chemicals that are linked to cancer and reproductive health effects. So removing phthalates is just the beginning.”


The Campaign for Safe Cosmetics is asking all cosmetics companies to sign a pledge to remove all EU-banned chemicals, and replace them with safer alternatives within three years.

Containing Chronic Wasting Disease

Throughout most of the Great Lakes region,
there are huge numbers of white-tailed deer. Deer don’t have the natural predators that they once did… so states rely on hunters to manage the deer herds. Recently, that’s become even more important with the discovery of a fatal disease. The Great Lakes Radio Consortium’s Rebecca Williams reports there’s extra pressure on hunters to keep the disease from spreading:

Throughout most of the Midwest/Great Lakes region, there are huge numbers of
white-tailed deer. Deer don’t have the natural predators that they once did…
so states rely on hunters to manage the deer herds. Recently, that’s become even
more important with the discovery of a fatal disease. The Great Lakes Radio Consortium’s
Rebecca Williams reports there’s extra pressure on hunters to keep the disease from spreading:


“How are you today? Successful morning, or are these from yesterday? This
morning… oh okay…”


Hunters are bringing their deer into a check station. Department of Natural Resources staff
determine the age of the deer by looking at their teeth. If it’s an adult deer, a technician
saws the head off so brain tissue and lymph nodes can be tested for chronic wasting disease.


(sound of deer head being cut off)


Chronic wasting disease, or CWD, affects white-tailed deer, mule deer and elk. It’s always
fatal. So far, there’s no evidence that CWD can hurt people or livestock. For now, most wildlife
managers are just worried about the health of the deer herds.


Western states such as Colorado and Wyoming have been dealing with CWD for decades. Wisconsin
found the disease in wild deer in early 2002. Illinois found the disease later the same year.
So far, it hasn’t shown up in wild deer in neighboring states, such as Indiana, Michigan or
Minnesota.


Wisconsin has a lot of deer crowded into a relatively small space, and that worries state
officials. Tami Ryan is a wildlife supervisor with the Wisconsin Department of Natural Resources.


“Some of the genetic research that’s been done to date on Wisconsin deer, they are not
resistant to CWD. It could be severely detrimental to the herd, which is why we feel so
strongly about trying to contain the disease where it exists and prevent it from spreading.”


Wisconsin’s attempting what state officials call aggressive herd reduction. At first, the
state wanted to kill all the deer in the heart of the disease eradication zone. Now, the state
wants to kill five of every six deer in those zones. That means reducing the deer to fewer than
five per square mile.


The Department of Natural Resources is trying to do this by making hunting seasons longer
and handing out more permits. In the disease eradication zones, people can hunt on private
land all fall and all winter – September to March.


Many hunters say they like the opportunity to take a few extra deer. Mike Snodgrass hunts
regularly in one of the areas where the state’s trying to reduce the herd.


“From just being out and observing the deer, there’s a huge number of deer out in the woods.
I’ll do my part, I enjoy the venison, and so I’ll take a couple of does out, no problem.”


The Department of Natural Resources says hunter participation is crucial for controlling
chronic wasting disease. That’s because the state doesn’t have nearly enough wardens to kill
all those deer.


State officials worried at first that CWD would turn hunters off from the sport. But from some
recent surveys, it’s been clear that most hunters say they understand the problem and they still
want to hunt where they’ve hunted every year – whether or not there are sick animals in those
areas.


The state’s also reaching out to private landowners. Most of the land in the disease zones is
privately owned. The state’s encouraging landowners to open up their land to more hunters.


Mike Albert is a landowner who hunts. He owns 275 acres near where the first three infected
wild deer were found. Albert says he’s hesitant to open up his land to strangers, but he does
let friends and family hunt on his land. He says something has to be done about chronic wasting
disease, but he says he’s afraid the state’s going too far.


“It’s not that I don’t feel a responsibility to help. As an ethical hunter when you’re asked to
just blatantly shoot every deer you see no matter how, it’s hard to overcome that. They’re asking
us to totally devastate our herd, ruin our tradition, and do all this stuff before we know for
sure whether it’s the right thing to do.”


Albert says more of the effort should be focused on understanding the disease before acting.
Researchers are still asking many questions about the disease itself. It’s still not known
exactly how the disease is transmitted.


Beth Williams is a veterinarian at the University of Wyoming. She’s also a leading expert on
CWD. Williams says there aren’t any proven methods for stopping CWD. She says killing off
much of the deer herd is controversial, but the state’s options are limited.


“I think it was a good idea for Wisconsin to see whether or not taking fairly radical steps
like they have to do their herd reduction, whether or not that might stop CWD. The alternative
is, based on everything that we know, if you don’t try and do something, the disease is then
going to spread.”


Williams says it’ll be years before anyone can tell whether reducing the deer herds
will help. But many people agree chronic wasting disease needs to be stopped as soon
as possible, before it spreads to deer herds in neighboring states.
