The VOC Project Advisory Group Meeting

The Network Center for the EANET, organized the EANET VOC Advisory Group Meeting in Manila, Philippines, as part of the EANET « Project for the feasibility for promotion of VOCs related capacity building in EANET » Project Activity in 2023.

The first meeting for the project took place in February 2023. As part of this project, it was decided to create an Advisory Group, composed of experts from Japan, the Republic of Korea, China, Thailand, and from the Network Center, to give guidance on feasible measurement methods, data analysis, identification of the target species to measure VOCs, and feasible reduction measures. During the meeting, the Advisory Group members considered methods like DOAS (Differential Optical Absorption Spectroscopy), canister sampling, sorbent tubes, and passive samplers. They emphasized the importance of source identification and reducing toxic VOCs, and discussed the use of low-cost sensors.

VOC Advisory Group Recommendations and Highlights

The VOC project Advisory group meeting involved thirty-six participants and facilitated in-depth information exchanges and discussions among project stakeholders and advisory group members. Recommendations for the project plan were compiled based on the insights gained from the laboratory and monitoring assessments during the mission.

The Advisory Group emphasized that the final goal of the project is to reduce Ozone and PM2.5 pollution. For this purpose, understanding the status of VOCs and exploring the best solutions for their reduction is key. The Advisory Group discussed VOCs measurement methodologies and a methodology for estimating Secondary Organic Aerosol (SOA) contribution and source apportionment of VOCs.

Among their recommendations, the Advisory group considered prioritizing monitoring of BTX (Benzene, Toluene, Xylene) in the Philippines and Mongolia. Methods such as Canister/Gas Chromatography/Flame Ionization Detection/Mass Spectrometry (GC/FID/MS) and Differential Optical Absorption Spectroscopy (DOAS) were recommended to be compared. Sampling should be conducted for 24 hours over two weeks at various locations. Capacity building for Volatile Organic Compounds monitoring was considered crucial. Re-establishing Canister/Sorbent Tube-GC/FID/MS methods (TO14/14a/15/15a) in the lab is recommended. Training, consumables, and support for monitoring and analysis were considered important. Developing Standard Operating Procedures (SOPs) for VOCs monitoring and formulating air quality guidelines are the key objectives.
