[Simultaneous analyses of gaseous and particulate sulfur in the atmosphere by X-ray fluorescence spectrometry--discussion on the results of observation and presentation of the problems involved in the methods of sampling and analysis (author's transl)].
Following the previous article, the results of observation are discussed in relation to meteorological conditions. The frequency distribution of gaseous sulfur concentrations (1 hr mean values) was bimodal as the result of the alternation of land and sea winds. The frequency distribution of particulate sulfur concentrations was also bimodal, but this can be rather ascribed to the variation of weather. The correlation between the concentrations of gaseous and particulate sulfur was not so great as was expected. Autocorrelations of the concentrations of gaseous and particulate sulfur were respectively investigated, and it was found that the variation of gaseous sulfur concentration showed daily cycle, and, against this, the variation of particulate sulfur concentration did not show appreciable daily cycle, but had weather correlation. Some discussions are presented concerning the selection of sampling points suitable for clarifying the behavior of sulfur in the atmosphere as well as the improvement of the methods of sampling and analysis.
