Unaccounted Lead Wheel Weights and Possible Fate

"About 4,000 t of lead in wheel weights are unaccounted for, but could include weights given or sold by retailers to anglers for making weights and lures; boaters for constructing keels and ballast; and hunters (bullet casters/reloaders) for making ammunition...."

Conclusion

"Much of the emphasis concerning lead wheel weights has been placed on losses during use. However, when viewing lead wheel weights through a model of stocks and flows, it appears that determining the fate of the unaccounted material may also need to be investigated more thoroughly, with a particular emphasis on the disposition of lead wheel weights collected by dealerships, fleet managers, repair shops, and tire retailers."
