Concentration and cumulative depositions of some major air pollutants (especially Lead Pb and Cadmium Cd ) was measured in six locations distributed with certain patern in Mosul city .It was possible to survey more than (10) separate rainfall storms during the period of study.
Locations near the city center exhibited the highest Cd and Pb value due to heavy traffic .
The level of Cd and Pb is still moderate, but due to probable effect on Tigris and groundwater as well as direct air quality, it is important to control sources of these two heavy metals in the future.
