17. Lead wheel weights...

Problem: When you take your car in for wheel balancing, mechanics will often install new wheel weights – small, metal pieces that attach to the rim and help adjust for the proper balance. For decades, these metal wheel balancing weights have been made out of lead.

Because of the large number of cars and trucks in the U.S., the total amount of lead used as wheel weights is staggering. According to the U.S. Geological Survey, about 65,000 tons of lead wheel weights are in use on the over 200 million cars and trucks that are driven in the U.S. About 2,000 tons of these weights fall from vehicles every year and into roadways. Most wheel weights are lost on city streets when vehicles hit curbs, bounce over potholes, stop or accelerate suddenly, or turn sharply. Once lost from the vehicle, these leady wheel weights release lead into the environment -- when they are worn down by traffic, lead is spread around by wind or water. And when roadsides are close to reservoirs or other water bodies used as sources of drinking water, this lead can end up in our drinking water. Lead dust can also be tracked by people and pets inside homes and other buildings.
