Our lead wheel weight educational awareness hypothesis is:
"If the public becomes more aware of the environmental dangers of
lead wheel weights and is given alternative wheel balancing choices then
there will be a decrease in lead entering the environment." TEAM DEAD WEIGHT

Our team lead wheel weight experimental hypothesis is:
"If lead wheel weights are exposed to natural environmental conditions
then soluble hazardous lead compounds will be formed.”

Study conducted by West Branch Iowa 7th grade Science Team "Dead Weight" February 27, 2009.
A special thank you to our science team advisor Dr. Hector Ibarra,
Dr. Michael D. Wichman, UIHL Iowa City Iowa, Dr. Robert A. Root, Retired and our parents.



Science research team "Dead Weight" recognizes the 
need to protect the public from exposure to lead hazards. 
There are no federal regulatory controls governing use of lead 
wheel weights. Environmental health hazards associated with lead 
wheel weights are a preventable problem. People are exposed to 
lead fragments and dust when lead wheel weights fall from motor 
vehicles onto the nation's roadways and are then abraded and 
pulverized by traffic. Lead wheel weights on and alongside roadways 
can contribute to soil, surface and groundwater contamination and 
pose hazards to downstream aquatic life.
       Lead negatively affects every bodily system. While it is 
injurious to people of all ages, lead is especially harmful to 
fetuses,children, and adults of childbearing age. Effects of lead 
on a child's cognitive, behavioral, and developmental abilities may 
necessitate large expenditures of public funds for health care and 
special education. Irreversible damage to children and subsequent 
expenditures could be avoided if exposure to lead is reduced.
