Determination of Volatile Organic Compounds in Mt. Tateyama Area (Altitude; 1,180m and 2,450m)

Abstract

At Mt. Tateyama (Murodo, Altitude; 2,450m) and a summit of Tateyama Mountain Range (Gondola Station, Altitude; 1,180m), 20 volatile organic compounds (VOCs) were determind.
The concentrations of VOCs at each site were as follows; benzene: <0.2μg/m³∼0.58μg/m³ and <0.2μg/m³∼0.55μg/m³, toluene: <0.2μg/m³∼1.14μg/m³ and <0.2μg/m³∼1.21μg/m³, and ethylbenzene: <0.2μg/m³ and <0.2μg/m³∼0.28μg/m³. Oher compounds were below the determination limit value (0.1∼2.5μg/m³).
The influence of East Asia, i.e., China and North Korea, and also the influence of Japan were considered to be the sources of VOCs detected at Tateyama Murodo and Gondola Station.
