A new study by an environmental group says there are high
concentrations of toxic chemicals called PBDEs and phthalates inside
many cars. The Ecology Center is calling for the chemicals to be phased
out. The Great Lakes Radio Consortium’s Tracy Samilton reports:
PBDEs are used as flame retardants in auto parts, and phthalates make
plastic parts more flexible. The study found that the heat that builds up
inside a car in the sun causes the chemicals to be released, which
increases exposure to humans.
Jeff Gearhart of the Ecology Center says there are plenty of safer
alternatives and the auto industry should use them. He says there are not
many studies on the effect of the chemicals on humans, but animal
studies show that they hurt reproduction and brain development.
“We should take a precautionary approach and we think that’s the
type of approach that many people take in their own lives.”
A spokesperson for the Alliance of Automobile Manufacturers says
flame retardant PBDEs make cars safer for people in the event of a fire,
and that PBDEs and phthalates are both safe.

A new report by an environmental group says car companies could be using
environmentally safer plastics in their automobiles. The Great Lakes Radio
Consortium’s Mark Brush has more:
The Michigan based Ecology Center finds that five out of the six top automakers
in the world get below average grades when it comes to the kinds of plastics
they use in their vehicles. The group says many the plastics in today’s cars
release toxic chemicals.
Charles Griffith helped author the report. He says there is one plastic the
car companies should work to phase out now.
“A good starting point for the car companies would be to commit to phasing
out PVC by the end of this decade. That would be a great place to start and
would send a strong signal that they intend to move in the right direction.”
Griffith says of all the plastics used in today’s cars, PVC plastics pose the
biggest threats to environmental and human health. A spokesperson
representing the automakers says the report is too negative.
He says it
fails to recognize the significant progress car companies have made in
moving toward environmentally friendly plastics.

For years, the government and environmentalists have been working to reduce lead exposure in the
environment. Lead can cause developmental damage to children and cause other health problems. The
government banned lead in gasoline. It banned lead shot in shotgun shells. There are efforts to get rid of lead
sinkers in fishing tackle. And now, environmentalists are trying to ban lead weights used to balance wheels.
And some companies and fleet operators seem willing to comply. The Great Lakes Radio Consortium’s Julie
Halpert has the story about the move to a less hazardous alternative:
When you buy a new car or get your tires replaced, manufacturers use lead weights, which clip onto the wheel
rim to make sure it’s evenly balanced. They use lead, because it’s heavy, dense. So a small amount by
volume is used.
Still, a few ounces of lead can be used on each wheel. And nearly every car and truck on the road has lead
weights. They’re the second largest use of lead in cars, next to lead acid batteries.
As long as the weights stay on the tires, they’re not a huge problem. But environmentalists are worried that
they come off too often. Many fall off when a car hits a pothole or collides with a curb. Then they’re run
over, ground down and get into the environment.
Each year, roughly 30-million pounds of lead are used to make wheel weights. A recent study estimates that
more than 300 tons of lead fall off vehicles each year in the Midwest alone. Jeff Gearhart is with the Ecology
Center which conducted that study.
“Many people don’t realize there’s a lot of lead in vehicles for this particular use and this is actually a fairly
small percentage of that lead actually falls off. But when you look at it as quantity, it’s pretty significant.”
The weights don’t just pose a problem on the road. Gearhart says there’s also danger when they’re not
properly recycled when new tires are put on and the weights are replaced. Another problem is when a car is
scrapped and then later when the parts are melted down, the lead can be released into the environment.
“Lead wheel weights are not managed very well as vehicles are scrapped and the difficulty in correcting the
management of these at the end of a life in a salvage yard or in a vehicle crusher or a shredder is very
challenging.”
He says the solution is to make sure lead is not used in the first place. Concerned about lead’s potential
health effects, Europe has already decided to ban lead wheel weights starting next year. And Gearhart is
pushing manufacturers who design for the U.S. market to do the same. He says substitute materials, such as
zinc, iron and tin, are readily available and work just as well as lead.
And with funding from the Environmental Protection Agency, the Ecology Center is making lead-free weights
available to those who service vehicle fleets.
(sound of weights being hammered onto wheel rims)
At the city of Ann Arbor, Michigan’s garage, a technician is banging zinc weights onto wheels. Tom
Gibbons helps manage this fleet of 400 city vehicles. Ann Arbor is the first city to switch to lead-free
weights.
“We realize lead is a problem in the environment and in the city, we’re really concerned about the
environment. We’re committed to doing as much as we can to protect it, so if we can take lead out of the
system, why not do it.”
Gibbons says the substitutes work just as well as lead weights. He says once the Ecology Center’s free
supply of weights runs out, the city will began buying non-lead weights, even though they’ll cost slightly
more.
But not everyone agrees with the idea of using other materials for wheel weights. Daimler/Chrysler doesn’t
plan to switch to lead-free weights for its U.S. models. The company is concerned the substitutes are costlier
and more difficult to install on wheels.
Other automakers are looking at eliminating the use of lead weights. Terry Cullum is with General Motors.
He agrees they’re currently an issue, but says the Ecology Center’s estimate of the number of weights that fall
off cars seems high to him. And, he says there’s no imminent danger to the public.
“I think if you look at this from a risk-based situation, we don’t view lead being used in wheel weights
applications as a risk, well, as a large risk, let’s put it that way.”
Even so, General Motors is considering moving to lead free weights. Cullum says that everywhere the
automaker uses lead is a concern. And since the company will have to stop using lead weights on the cars and
trucks it sell in Europe, he says it might be easier just to take them out of all GM vehicles. Still, Cullum says
the substitutes present a big engineering challenge: because they’re not as dense. It takes bigger pieces of
metal to make the same weight. So, they take up more space on the wheel than lead weights.
“It becomes an issue, in terms of where do you put it on the wheel, how do you do it in such a way that it
doesn’t actually interfere with the actual operation of the wheel or the brake systems. That is an issue that is
going through research and engineering right now.”
But Cullum’s optimistic that the issue can be addressed. And other auto makers, such as Honda, are forging
ahead with lead-free weights on at least one of their model.
Still there’s resistance from U.S. tire retailers. The Tire Industry Association says the weights don’t fall off
wheels. And the tire retailers say the lead weights are properly recycled. The group has no plans to stop
using lead weights if they’re not legally required to.
Jeff Gearhart with the Ecology Center says that denial of the problem is a big mistake. He says if
manufacturers and tire retailers cooperated, they could get a substantial amount of lead out of the
environment within a few years.
“There is the potential to make a really significant impact here. We’re talking hundreds of tons of lead
released into the U.S. to the environment that can be eliminated. So we think this is a high priority project,
not just for us, but we think it will be for states and for EPA to look at how to facilitate this transition to
cleaner wheel balancing.”
The Environmental Protection Agency is starting to look at the issue. It plans to conduct a study within the
next year to get a better understanding of the problem and see how lead weights are handled. Then, they’ll
issue guidelines for consumers and tire recyclers late next year. That means the public will be more aware of
the use of lead wheel weights and the potential for toxic exposure. Usually, that means public pressure for
change, whether some automakers and tire retailers like it or not.

(tire balancing sound)
When you go to get new tires, or to have them rebalanced, the mechanic often
attaches lead weights to the wheel rims. The weights help ensure a smooth
ride and make sure tires wear evenly.
But two recent studies found some of these wheel weights fall off. The
researchers say that adds up to 275 tons of lead dropped onto roads in the
region every year. One of the studies found the soft metal gets ground up
and deposited near curbs.
Jeff Gearhart is with the Ecology Center. His group is concerned the lead
dust could be tracked into homes and washed into water supplies. So the
group is working with tire retailers to switch to non-lead wheel weights.
“Lead, in commerce, being used in a way where there’s exposure, is something
we should move away from. The European Union has banned the use of these
weights and we think that that is going to be needed in the U.S. as well.
Gearhart says the Ecology Center will help retailers cover the cost of
switching to non-lead weights.

Environmentalists scored a huge victory at the polls earlier this month, when a Midwestern city and its
surrounding townships agreed to a tax to preserve a belt of green space. The plan marks one of the first
locally funded efforts in the Midwest to fight sprawl. Sprawl often occurs when developers pave over
farmland and other natural resources to create strip malls and subdivisions. The Great Lakes Radio
Consortium’s Julie Halpert takes a look at whether this plan will fulfill its promise to curb urban sprawl:
Voters in Ann Arbor, Michigan gave the nod to a 30 year tax to preserve roughly 8,000 acres of land. It’s
one of the first measures in the Great Lakes states to set up a major regional funding plan for curbing
growth. Sprawl is prominent in the area and Ann Arbor and its surrounding townships will share the
preservation costs. The proposal will allow the city to purchase easements on land. That will prohibit the
land’s future development and preserve it.
Elizabeth Humphrey is the director of the Growth Management Leadership Alliance in Washington, D.C.
She says citizens are fed up with seeing houses overtake park lands. So anti-sprawl initiatives, like Ann
Arbor’s, are gaining popularity among all political parties.
“I think the loss of open space is the one thing that we all see as the big threat of sprawl. It’s tangible.
You can see it in the field you used to play in when you grew up. It disappears and that’s visceral. And I
think that appeals to everybody who’s really concerned about how we’re growing.”
Humphrey says that Ann Arbor’s program is a good approach, since it focuses on regional development.
And while scenic areas like Boulder, Colorado and Portland, Oregon have greenbelts in place, the
Midwest generally hasn’t followed. But that could all change now, according to Mike Garfield. He’s
director of The Ecology Center, which spearheaded the plan.
“I think that what we did Tuesday in Ann Arbor and Ann Arbor township could lead to a wave of new
conservation easement programs and farmland programs around Michigan and throughout the Great
Lakes Region.”
Garfield says his group’s win showed it was possible to successfully trounce a formidable opponent: the
homebuilders. Homebuilders feared the plan would limit housing choices. They spent a quarter of a
million dollars to fight it. Garfield’s hopeful that this victory will help preserve Ann Arbor’s high quality
of life and its vital downtown. In a mere ten minutes, he’s able to walk to work without fighting traffic.
And he thinks the ‘yes’ vote indicated that Ann Arbor residents value that kind of living. But Garfield
realizes not everyone in Ann Arbor agrees with him.
“And of course there were some people in town who are not developers and home builders who opposed
it because it was a tax or because they believed some of the arguments or they didn’t trust city hall or
something like that.”
Niki Wardner is one of those people. She lives in a ranch on an acre of land overlooking a public golf
course in Ann Arbor’s wooded residential section. A handful of vote no signs are perched against her
door. Wardner lobbied heavily with other citizens against the Ann Arbor plan. She thinks 30 years is
way too long for a tax.
“They’re going to bond this issue, this proposal, i.e., take a mortgage out. We can never change it.
There’s no accountability. How do we know 10 years, 15 years, 20 years, 30 years, what’s going on with
it?”
Wardner’s concerned that this plan was rushed to the ballot without details on how it would work and
what kind of land will be purchased. She thinks something needs to be done about sprawl. But she’s not
sure this is the solution. And she also thinks residents won’t agree to the increased development that will
likely occur downtown and where she lives.”
“Personally, you know, I bought my piece of property because I live on a park and you know, we all like
trees and green space and I don’t think anyone wants townhouses or condos or a five story building in
their backyard.”
And building more homes downtown is a central part of the plan. Doug Kelbaugh is Dean of The
University of Michigan’s College of Architecture and Urban Planning. He says that to avoid sprawling
out, more people need to live in the city’s center.
“There aren’t enough people living downtown. It’s the living downtown, the downtown residential
development, that will do the most to decrease sprawl, decrease the number of commute trips, decrease
the length of commute trips, increase the walkability, increase the livability and the urbanity of Ann
Arbor lifestyles.”
Kelbaugh says if that denser development occurs, that means houses will have to be built on smaller lots.
That could curb housing price spikes by adding to housing supply. He said that if carried out responsibly,
Ann Arbor’s plan could be a small, but important first step in attacking sprawl.
“As long as gasoline is so cheap and farmland is so cheap, we will tend to have sprawl in America. This
is a major model that’s prevailed in America for 50 or 60 years, if not a little longer and it’s going to take
a little while to turn it around. But this is a significant beginning.”
Other towns are looking to preserve green space just like Ann Arbor’s doing. They’ll be closely watching
to see if it works.
