Description
Atmospheric hydrogen peroxide (HOOH) and organic peroxides (ROOHs) were measured during the period of August 23-26, 1998 at Shimosha (ca. 700 m a. s. l), located on the southern slope of Mt. Oyama (35°26' N, 139°14' E, 1252 m a. s. l.), Kanagawa Prefecture, Japan in order to evaluate the possible effect of these peroxides on the decline of Japanese fir (Abies firma Siebold et Zuccarini) forests on the mountain. Peroxides were measured by fluorometry after an enzymatic separation of these peroxides, which followed the collection of the atmospheric peroxides by the stripping coil method. The concentrations of ozone (O3), nitrogen oxides, and meteorological factors were also measured during the study period. HOOH concentrations ranged from 0.8 to 4.0 ppbv with the highest reading in the daytime and the lowest in the night-time. O3 concentrations that ranged from 3.1 to 70 ppbv showed a similar temporal variation as that of HOOH; thus, there is a strong correlation between these two photooxidants. ROOHs concentrations were in the range of 0.6-2.2 ppbv and showed a reverse diurnal variation to the HOOH. These results imply that HOOH is photochemically produced during daytime, as is O3, whilst ROOHs are generated by various reactions, such as the reactions of O3 with non-methane hydrocarbons (NMHC), in both the day-and night-time. As these peroxides occur with relatively higher concentrations on the mountain, the peroxides may have harmful effects on the fir trees.
