Chemicals that are suspected of being hazardous to human health
are being found in household dust. The chemicals are flame retardants
used in everything from carpet padding to TV sets. The Great Lakes Radio
Consortium’s Mark Brush has more:


The chemicals are known as poly-brominated-diphenyl-ethers, or PBDEs.
Scientists already knew that these flame retardant chemicals where found in
food. Now researchers are finding the chemicals, in household dust.


Heather Stapleton is a research chemist at the National Institute of
Standards and Technology. She authored a study recently published by the
American Chemical Society.


“I went out and collected some house dust samples from areas within the
Washington D.C. metropolitan area, and brought these samples back to the lab
and just did a preliminary measurement looking at PBDE’s in the house dust
samples and found surprisingly high levels in the house dust.”


Researchers are most concerned about how the chemicals affect developing
babies. Babies have more contact with household dust than the rest of us.
The chemicals have been found to cause developmental and nervous system
damage in rats and mice.

Survey: Parents Missing Important Asthma Triggers

New research suggests that while parents of children who have asthma
try to protect their youngsters from the things that trigger attacks,
those measures often aren’t very helpful. The Great Lakes Radio
Consortium’s Michael Leland reports:


Researchers at the University of Michigan found 80 percent of the
parents they surveyed were doing something to prevent attacks, but
often missed important measures. For example, a quarter of the parents
said a smoker lived in the same house as a child with asthma, but they
hadn’t done anything about it.


In one case, the parent of a child with pollen-triggered asthma bought
a new mattress cover, but didn’t close windows to keep pollen out of
the house.


Dr. Michael Cabana is a U of M pediatrician who led the study. He says
many parents also needlessly buy products they think will lessen asthma
symptoms.


“A lot of times, parents may get more information from other commercial
sources more often than the time they have to spend with either their
primary care doctor or their doctor who might be a sub-specialist in
asthma. So I think physicians have to do a better job putting that
information into perspective.”


Dr. Cabana suggests parents talk to their child’s doctor about asthma
triggers before spending money on asthma-related products.

Trash Burning Can Threaten Human Health

For most of us, getting rid of the garbage is as simple as setting it at the curb. But not everyone can get garbage pick-up. So, instead, they burn their trash. The Great Lakes Radio Consortium’s Lester Graham reports… that choice could be affecting your health:

For most of us, getting rid of the garbage is as simple as setting it at the curb. But not everyone
can get garbage pick-up. So, instead, they burn their trash. The Great Lakes Radio Consortium’s
Lester Graham reports… that choice could be affecting your health:


(sound of garbage trucks)


It’s not been that long ago that people everywhere but in the largest cities burned their trash in a
barrel or pit in the backyard. That’s not as often the case these days. Garbage trucks make their
appointed rounds in cities, small towns, and in some rural areas. But they don’t pick up
everywhere… or if they do offer service… it’s much more expensive because the pick-up is so far
out in the country.


Roger Booth lives in a rural area in southwestern Illinois. He says garbage pick-up is not an
option for him.


“Well, we burn it and then bury the ashes and things. We don’t have a good way to dispose of it
any other method. The cost of having pick up arranged is prohibitive.”


He burns his garbage in the backyard. Booth separates bottles and tin cans from the rest of the
garbage so that he doesn’t end up with broken glass and rusty cans scattered around. A lot of
people don’t do that much. They burn everything in a barrel and then dump the ashes and scrap in
a gully… or just burn everything in a gully or ditch. Booth says that’s the way most folks take
care of the garbage in the area. No one talks about the smoke or fumes put off by the burning.


“I haven’t ever thought much about that. So, I don’t suppose that I have any real concerns at this
moment. I don’t think I’m doing anything different than most people.”


And that’s what many people who burn their garbage say. A survey conducted by the Zenith
Research Group found that people in areas of Wisconsin and Minnesota who didn’t have regular
garbage collection believe burning is a viable option to get rid of their household and yard waste.
Nearly 45-percent of them indicated it was “convenient,” which the researchers interpreted to
mean that even if garbage pick-up were available, the residents might find more convenient to
keep burning their garbage.


While some cities and more densely populated areas have restricted backyard burning… state
governments in all but a handful of states in New England and the state of California have been
reluctant to put a lot of restrictions on burning barrels.


But backyard burning can be more than just a stinky nuisance. Burning garbage can bring
together all the conditions necessary to produce dioxin. Dioxin is a catch-all term that includes
several toxic compounds. The extent of their impact on human health is not completely known…
but they’re considered to be very dangerous to human health in the tiniest amounts.


Since most of the backyard burning is done in rural areas, livestock are exposed to dioxin and it
gets into the meat and milk that we consume.


John Giesy is with the National Food Safety and Toxicology Center at Michigan State University.
He says as people burn garbage, the dioxins are emitted in the fumes and smoke…


“So, when they fall out onto the ground or onto the grass, then animals eat those plants and it
becomes part of their diet. And ultimately it’s accumulated into the animal and it’s stored as fat.
Now, particularly with dairy cattle, one of the concerns about being exposed to dioxins is that
then when they’re producing milk, milk has fat it in, it has butter fat in it. And the dioxins go
along with that.”


So, every time we drink milk, snack on cheese, or eat a hamburger, we risk getting a small dose
of dioxin. Beyond that, vegetables from a farmer’s garden, if not properly washed, could be
coated with dioxins. And even a miniscule amount of dioxin is risky.


John Giesy says chemical manufacturing plants and other sources of man-made dioxin have been
cleaned up. Now, backyard burning is the biggest source of dioxins produced by humans.


“So, now as we continue to strive to reduce the amount of dioxins in the environment and in our
food, this is one place where we can make an impact.”


“That’s the concern. That’s the concern, is that it’s the largest remaining source of produced
dioxin.”


Dan Hopkins is with the Environmental Protection Agency. He says, collectively, backyard
burning produces 50 times the amount of dioxin as all the large and medium sized incinerators
across the nation combined. That’s because the incinerators burn hot enough to destroy dioxins
and have pollution control devices to limit emissions. Backyard burning doesn’t get nearly that
hot and the smoke and fumes spread unchecked.


The EPA wants communities to take the problem of backyard burning seriously. It wants state
and local governments to do more to make people aware that backyard burning is contaminating
our food and encourage them to find other ways to get rid of their garbage…


“(It) probably won’t be a one-size-fits-all solution, but by exchanging successful efforts that other
communities have had, we should be able to help communities fashion approaches that have a
high probability of success.”


But… public education efforts are expensive… and often they don’t reach the people who most
need to hear them. The EPA is not optimistic that it will see everyone stop burning their garbage.
It’s not even a goal. The agency is just hoping enough people will find other ways to get rid of
their trash that the overall dioxin level in food is reduced.

There’s an effort underway to get people to stop burning their trash. The Great Lakes Radio
Consortium’s Lester Graham reports that experts have found that toxins from backyard burning
can get into food:


Often, garbage truck routes don’t include rural areas, so many people there just burn their trash.
But that can lead to toxins getting into food. John Giesy is with the National Food Safety and
Toxicology Center at Michigan State University.


“Well, when we burn waste in a barrel, the dioxins will be in the gas and in the particulates. And,
so, they go downwind, but those particulates ultimately fall out.”


And they end up on the grass that livestock eat. We end up taking in the dioxins in the meat and
milk products that we eat. Because backyard burning is the largest human-caused source of
dioxins, the Environmental Protection Agency is working with states and communities to try to
get people to get rid of their trash some other way.
