Posted on by Aurélia Lemoine

27 October 2026

The Drafting Committee Meeting on the Technical Training Guidance for VOC Sampling under EANET was held on 4–7 August 2026 at the Asia Center for Air Pollution Research (ACAP) in Niigata, Japan, bringing together experts from seven EANET Participating Countries including Cambodia, China, Japan, Mongolia, the Philippines, the Republic of Korea, and Viet Nam, and partner institutions. The meeting focused on developing practical guidance for ambient VOC monitoring through technical discussions, hands-on demonstrations, and scientific exchange on VOCs, ozone, and secondary organic aerosols (SOA).

 .

Developing the Technical Training Guidance for VOC Monitoring

On 4–5 August, experts from EANET Participating Countries taking part in the project Capacity Building in Promoting VOCs in the EANET worked together to develop the Technical Training Guidance for Ambient VOC Monitoring.

Through technical discussions and peer review sessions, participants examined a range of monitoring approaches, including canister sampling, sorbent tube sampling, charcoal tube sampling, passive samplers, and online monitoring technologies. The discussions placed strong emphasis on practical sampling experience gained under diverse national and environmental conditions, such as high-altitude, large day-time temperature difference and high-humidity conditions. Participants shared lessons learned on sampling procedures, instrument operation, calibration, quality assurance/quality control, detection limits, sample storage, data interpretation, and field operation challenges. These exchanges helped identify common technical needs and good practices that can support more harmonized VOC monitoring across the region, while also providing useful references for countries seeking to develop or strengthen their national ambient VOC guidelines, standards, and monitoring protocols.

Emissions inventories kick-off meeting

1. Background

EANET is working to reduce acid deposition and air pollution in Northeast and Southeast Asia. It is an intergovernmental initiative established in 2001 including 13 Participating Countries initially focused on acid deposition. In 2021, EANET expanded its scope to cover broader air pollution issues and established a Project Fund mechanism to promote cooperation with other organizations outside of EANET.

EANET’s activities are guided by its five-year Medium-Term Plans and a detailed Work Programme and Budget including projects, approved by the Participating Countries every year. A project called “Stocktaking and Methodological Assessment of Emissions Inventories and Source Apportionment of Air Pollution in Southeast Asia” has been approved for implementation in 2024, at the Twenty-fifth Session of the Intergovernmental Meeting (IG25) on the EANET, as a Project Activity, funded by the EANET Project Fund and implemented in partnership with the Asian Institute of Technology, Regional Resource for Asia Pacific (RRC.AP/AIT).

.

2. Objectives

Emissions inventories and source apportionment of air pollution are fundamental elements of an air quality management framework. They enable policymakers, government regulators, and experts to better understand the sources of air pollution and their contribution to ambient air quality and identify appropriate policies. Many emissions inventory and source apportionment studies have been conducted in the EANET region.

This project aims to collate and analyze relevant key studies based on research and consultations with EANET National Focal Points and make these studies available as a database on the EANET website. The project will also identify follow-up opportunities and projects to work emissions inventories and/or source apportionment in the region.

An inception meeting of the project will be organized on Tuesday 26 March 2024 at the UN Conference Center (UNCC), meeting room B,  in Bangkok, Thailand. The objective of the meeting is to better understand the emissions inventory/ source apportionment situation in Southeast Asia and discuss with potential project partners the detailed activities to be carried out in the project.

Opening Session

Dr. Isabelle Louis, Deputy Regional Director of UNEP Asia Pacific office, opened the EANET Awareness Workshop in 2022 by delivering the opening remarks, followed by welcome remarks from Mr. Kenichiro Fukunaga, Deputy Director General in charge of Administrative Management at the Asia Center for Air Pollution Research (ACAP).

Key messages conveyed in the remarks celebrated the imminent release of the Fourth Periodic Report on the State of Acid Deposition in East Asia (PRSAD4) and the opportunities ahead for the EANET, in line with the expansion of its scope to air pollution, including the launch of the EANET Project Fund.

General Lecture – Key Findings from the Fourth Periodic Report on the State of Acid Deposition in East Asia (PRSAD4)

Since 2006, the EANET has been developing Periodic Reports on the State of Acid Deposition in East Asia (PRSADs), published every five years, and aiming at providing high-quality data to be used for research, formulation of policies, and measures to reduce the impacts of acid deposition and related air pollutants on the environment. In 2022, the Fourth Periodic Report on the State of Acid Deposition in East Asia (PRSAD4), will be released.

Prof. Meng Fan, Former Chairperson of the PRSAD4 Drafting Committee and Deputy Director General in charge of the Network Center for EANET, Asia Center for Air Pollution Research (ACAP), presented the General Lecture: Key Findings from the Fourth Periodic Report on the State of Acid Deposition in East Asia (PRSAD4). Findings and recommendations from the PRSAD4 highlighted the improvement of sulfur dioxide-related air pollution mostly in North-East Asia, while nitrogen deposition, particulate matter, nitrogen oxides, and ozone-related pollution were detected at a high level in the EANET region. The importance to continue deploying more monitoring sites was expressed.

Panel Discussion – From data to policy, good practices for evidence-based and data-driven policies in East Asia

The Panel Discussion gathered renowned scientists and key policymakers from the EANET Participating Countries. Discussions focused on the importance of regional cooperation and multilateralism to address global environmental problems including acid deposition and air pollution. Findings from the PRSAD4 were also discussed, in the specific context of Malaysia, Mongolia, Thailand, and the Philippines. Most panelists highlighted the incredible capacity-building efforts led by the EANET in the past twenty years, on emission inventories, acid deposition regulations, and monitoring support which have indirectly contributed to the development of regional policies. Finally, the panel also shared thoughts on the role EANET may play by helping fill the gap of the right to information on air pollution, as the right to a clean environment and clean air was recently included as a human right by the United Nations.

Capacity Building in the EANET – The Individual Training 2022 Laboratory Session

Posted on by Aurélia Lemoine

19 January 2023 – Niigata, Japan

As part of the EANET Individual Training in 2022, a session in the laboratory was held by the Network Center for the EANET (NC) in December 2022. It aimed at providing practical capacity building to representatives from the EANET Participating Countries on wet and dry deposition monitoring.

.

Practical Field Training

The Individual Training has been conducted as a regular activity yearly by the NC in Niigata, Japan,  to improve the various monitoring skills of the representatives from the EANET Participating Countries.

In 2022, the laboratory session of the training was held in person in Niigata, Japan, at the Asia Center for Air Pollution Research (ACAP). A representative from the Environmental Management Bureau (EMB) of the Department of Environment and Natural Resources (DENR) from the Philippines completed the training.

Held from 11 to 17 December 2022, the training aimed at developing professional expertise and knowledge of wet deposition (precipitation sample) and dry deposition (4 Stage Filter Pack).

The laboratory session consisted of various technical exercises focusing on specific topics and practical outputs including pH and electric conductivity, filter pack sampling, and standard operating procedures of inorganic ions analysis. Through these exercises, laboratory work techniques were demonstrated and explained. These included maintaining a steady temperature during the measurements of pH and electric conductivity, how to clean laboratory wares, and understanding differences in the sampling when using a gas volume meter or a gas flow meter, for filter pack sampling.

.

The training also included a site visit at the Niigata – Maki Station, where the trainee observed automatic rainwater samplers, sampling setups for water-insoluble and water-soluble organic carbon, and filter pack samplers for particulate matter, gases, and carbons. This activity helped familiarize him with the field equipment used for air quality monitoring. In addition to the original training program, instructors shared knowledge on black carbon analysis (sampling, analysis, and instrument operation), atmospheric microplastics analysis, and PM2.5 data processing.

.

Ways Forward

The expected outcome of the laboratory session of the Individual Training is for the participant to disseminate experience and knowledge to colleagues in his country. The NC continuously provides support in this dissemination effort.

The  Individual Training program is a 2022 EANET Project activity, which received support from the governments of Japan and the Philippines.
