An examination of ambient air lead monitoring data was used to demonstrate success of banning the import and use of leaded gasoline in Bulgaria. From 1996-2007 air lead levels in Varna, the third largest city, decreased up to 63-fold.
This research was partly supported by the National Institute for Occupational Safety and Health (NIOSH) Education and Research Center at the University of Cincinnati Grant #T42/CCT510420.
