A small, time efficient and sensitive instrument for the continuous analysis of very volatile organic compounds (VOCs) with a boiling point lower than 100 degrees C in addition to the analysis of VOCs with a boiling point in the range of 100-150 degrees C was developed and applied to the measurement of VOCs in the course of university research and environmental monitoring. VOCs, such as n-hexane, acetone, ethyl acetate, alcohols, benzene, toluene and xylene, were continuously measured once every 30 min. The detection limits of hexane, ethyl acetate, benzene and toluene at a preconcentration time of 10 min were 0.

- A study analyzed low-level volatile organic compounds (VOCs) in Kyoto City using passive samplers, focusing on compounds like benzene and toluene.
- The samplers were placed at urban sites for 7-14 days and in mountainous areas for 30 days, employing activated carbon to collect VOCs and measuring them with FID-GC.
- Results showed elevated benzene levels initially exceeded environmental standards but decreased over time, likely due to reduced benzene in gasoline and regulatory measures from the Pollutant Release and Transfer Register (PRTR) Act.
