"The U.S. has worked to get lead out of gas and out of paint, but the biggest source of lead in a consumer product is still on roadways. It’s in the form of wheel weights, used to balance the tires on our cars. The Environmental Protection Agency says about 1.6 million pounds of lead fall off of vehicles each year, and it winds up in the environment. A handful of states is leading the effort to ban lead wheel weights."
