Recently, it is especially attached importance to the problem that the balances in the ecosystem must be kept, In many hazardous substances causing environmental pollutions that make loss the balances, especially, mercury-related pollution has become an object of much concern. The aim of this investigation is to obtain the numerous experimental data necessary for analyzing the diffusion-transfer processes of mercury vapor in the atomospheric air. On this study, we have kept the mind that we should hold the far level to the saturated vapor of mercury so as to be depended upon actual circumstances in the proceeding of pollution. Moreover, the multivariate analysis by the computer was introduced to analyze quantitatively several elements on the experimental condition or individual relation between the data which several physical variables remove arbitrarily in the process of diffusion-transfer of Hg vapor. Consequently, it was found that the distribution of mercury level in air at the transfer processes was closely related to the temperature of the mercury emission source and considerably differed from a definite view hitherto known.

A rapid and simple method for the determination of the sorbic acid and sorbates in jam and marmalade was studied by means of high performance liquid chromatography. By this method, tedious pretreatments such as extraction and filtration were omitted so that the time required for analysis could be within 30 min. Half of the examined non-preserve jams and marmalades contained less than 500mg/kg of sorbicacid, but preserve jams did not contain it.
