| Abstract: | A total of 19 elements in the samples of atmospheric deposition collected in Kawasaki, Japan, were determined by neutron activation
analysis, ICPAES and flame photometry. The amounts of soil dust depositions were larger in springs and those of Sb and Zn
depositions were larger in summers than in the other seasons. The values of the enrichment factors were higher for Sb and
Zn than for the other elements determined throughout the sampling period. A factor analysis showed that the two elements were
characterized as industrial components. Rubber products like tires that contain noncombustibles and rubber accelerators were
a possible origin of high concentrations of Sb and Zn in the present samples. |
