Abstract

Simultaneous sampling of 26 AVOCs (anthropogenic volatile organic compounds), namely seventeen chlorinated hydrocarbons (CHs), six monocyclic aromatic hydrocarbons (MAHs), three dicyclic aromatic hydrocarbons (DAHs), in the ambient air and atmospheric water was performed in an urban area (Shinjuku), mountainous area (at the southeastern foot of Mt. Fuji; 1284 m a.s.l.), and the free troposphere (at the top of Mt. Fuji; 3776 m a.s.l.) from 2007 to 2010. The atmospheric concentration of the AVOCs in 2010 was the highest at the top of Mt. Fuji (average in July: 11.6 ppbv, n=5) and then in Shinjuku (average in October, November, and December: 7.9 ppbv, n=52) and at the foot of Mt. Fuji (average in July: 6.8 ppbv, n=9). It was found that the concentrations of the MAHs at the top of Mt. Fuji were extremely high compared to those at Shinjuku and other high altitude sites, suggesting a highly suspicious contamination near the sampling site at the top of Mt. Fuji. The mean concentrations of the total AVOCs in the rainwater (15.8 nM, n=8) at the foot of Mt. Fuji and in cloud water (15.7 nM, n=19) at the top of Mt. Fuji were higher than those in the dew water (5.33 nM, n=15) and rainwater (3.36 nM, n=30) at Shinjuku. These results indicated that the enrichment of AVOCs in the atmospheric water was strongly influenced by factors other than the concentration of the AVOCs in the ambient air, temperature, and hydrophobicity of each AVOC.
