TEAM DEAD WEIGHT STUDYS THE SOLUBILITY OF TOXIC LEAD WHEEL WEIGHTS.

"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. It is
important that we make sure that the water we drink and the air we
breathe is free of lead." TEAM DEAD WEIGHT

Acetic acid-producing bacteria are present throughout 
the world. Nitric acid is present in acid rain from automobile and 
industrial pollution. The TCLP leaching solution uses acetic or nitric
acid to represent the types of acids produced during the biological 
decomposition of waste in a landfill.
 
Definitions of TCLP on the Web:
 
Toxicity characteristic leaching procedure (TCLP) is a soil sample 
extraction method for chemical analysis.

Toxic Characteristics Leaching Procedure, a test used to determine 
whether a solid waste is also classified as a hazardous waste.

Analytic test method used to measure compliance with the metal

A procedure designed to determine the mobility of both organic and 
inorganic analytes present in liquid, solid, and 
multiphasic wastes. ...

A test conducted to predict the leachability of a hazardous waste 
from a lined landfill containing 95% municipal waste and 5% hazardous
 waste. For this reason during TCLP the waste is diluted 20:1 with an 
acid and the resulting waste extract tested for metals. ...

TCLP analysis simulates landfill conditions and is designed to 
determine which/if specific contaminants identified by the 
US Environmental Protection Agency are present in landfill leachate.

Toxicity Characteristic Leaching Procedure (TCLP) 
The TCLP is most commonly used by the EPA and state regulatory 
agencies using a leaching solution of acetic acid to simulate 
co-disposal of industrial and non-industrial waste in a municipal


          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.
