Atmospheric trace elements collected with use of passive sorption sampling
- 33 Downloads
Instrumental Neutron Activation Analysis (INAA) was used to determine trace elemental composition of air. Continuous simultaneous sampling of air contaminants during two weeks in 75 sites of Samarkand city of Uzbekistan was performed with use of passive sorption method on polyethylene collectors. In addition samples of snow were collected. Enrichment factors for elements on sorption collectors and in snow water were calculated. The data obtained allowed to make conclusions on speciation and possible sources of various trace elements in the air and their distribution over the studied region.
