| Abstract: | Atmospheric particulate samples were collected at the geographic South pole, using cellulose and polycarbonate filters and
cascade impactors. The samples were analysed for 40 elements by instrumental neutron activation analysis. From the filter
samples atmospheric concentrations for 33 elements could be obtained. The highest atmospheric concentrations were found for
S: 49 ng/standard cubic meter (SCM) of air, Na: 3.3 ng/SCM and Cl: 2.6 ng/SCM. In the cascade impactor samples, only a few
elements were observed above blank. For these elements it could be concluded that they are associated for over 80–90% with
submicron size paricles. |
