文摘Determined with ICP-MS, new isotope abundance ratio data of lead for Beijing and Changdao aerosols was presented, in comparison with literature data for Chinese urban aerosols. ^206Pb/^207Pb ratio falls into a range from 1.13 to 1.18 for urban aerosols and less influenced by vehicle exhaust emission after phase-out of leaded petrol in 2000 in China. Major lead pollution sources may probably include coal combustion, oil combustion,re-suspended dust, metallurgical industry and use and production of cement.
