The State of Acid Deposition in East Asia, from data to policy – Join us on 20 June!

.

The registration is now closed.

.

1. Background

The Acid Deposition Monitoring Network in East Asia (EANET) was established in 2001 as a regional intergovernmental network to promote cooperation among countries in East Asia to address acid deposition problems. The Network is composed of 13 Participating Countries and its main objectives are:

    • to create a common understanding of the state of acid deposition problems in East Asia;
    • to provide useful inputs for decision-making at the local, national, and regional levels aimed at preventing, or reducing adverse impacts on the environment caused by acid deposition;
    • and to contribute to cooperation on the issues related to acid deposition among the participating countries.

In the last 20 years, the EANET has made excellent progress in acid deposition monitoring cooperation. The Network has fostered a regional acid deposition monitoring methodology and scientific exchange platforms which have contributed gradually to solving acid deposition problems in East Asia.

However, due to rapid economic growth and industrialization, many countries in the East Asia region are still facing serious threats from acid deposition related pollutants, in a more global context where almost the entire global population (99%) breathes air that exceeds the World Health Organization’s air quality limits, hindering populations’ right to a healthy environment.

Since 2006, the EANET has been developing Periodic Reports on the State of Acid Deposition in East Asia (PRSADs), published every four to 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), prepared by a Drafting Committee composed of members from the 13 EANET Participating Countries, will be released.

In November 2021, the Secretariat for the EANET organized the EANET Science and Policy Dialogue outreach event. In the results of the survey from the EANET Science and Policy Dialogue Event Report, it was suggested to discuss the findings from the Fourth Periodic Report on the State of Acid Deposition in East Asia (PRSAD4).

In November 2021, the IG23 approved the Work Programme and Budget of EANET in 2022, among which Objective 4, Activity 10: Promotion of public awareness on acid deposition, including other priority chemical species. In this respect, and in line with the efforts to facilitate the sharing of a common understanding of atmospheric environmental issues among the scientific and policy-makers communities, the EANET Awareness Workshop in 2022 will be organized virtually on Monday, 20 June 13:00-16:00 (ICT) under the name “The State of Acid Deposition in East Asia – from data to policy”.

.

2. Objectives and Participants

The EANET Awareness Workshop is expected to increase public understanding of acid deposition issues, appreciate the work achieved in the last 20 years by the EANET from the monitoring, research, and policymaking perspectives, and generate collaboration ideas for future EANET Projects, based on the findings and recommendations from the PRSAD4.

The EANET Awareness Workshop is open to the public, but will mainly be attended by the EANET National Focal Points, Scientific Advisory Committee members, policymakers and national researchers and scientists of the Network’s 13 Participating Countries, and representatives of partner organizations working on acid deposition and air pollution-related issues.

.

3. Programme

The virtual event will focus on sharing key findings from the PRSAD4, from the lead authors’ perspective, and provide some highlights for EANET Participating Countries’ policy-makers and other representatives, by sharing recommendations (on inputs for policies, technological improvements, and best practices…). The goal is to provide a discussion forum to brainstorm ideas to foster future projects and cooperation in the region.

The Network Center for the EANET releases the Data Report 2024

 

17 April 2026

(This post has been updated from the original post, published on 20 February 2025).

Composed of data collected in 2024, comprising atmospheric deposition and air pollution monitoring data endorsed by the Scientific Advisory Committee (SAC) end of 2025, the “Data Report 2024” and the “Report of the Inter-laboratory Comparison Project 2024” have been uploaded in open access on the EANET website.

.

What is EANET data?
Figure 1 – Location of acid deposition monitoring sites in 2019 (access the most recent sites’ information on the EANET Site Information page)

In the context of the resolution on promoting regional cooperation on air pollution to improve air quality globally, adopted in UNEA-6 in March 2024, the importance of referring to high-quality data for air quality management has never been greater.

Covering the area of 13 countries, from Irkutsk (Russia) in the North to Lombok (Indonesia) in the South, Ochiishi (Japan) in the East, and Mandalay (Myanmar) in the West, the EANET’s total surface is extremely wide and diverse.

Since 1998 (during the preparatory phase activities of the Network), the EANET has deployed monitoring stations in urban, rural, and remote locations to monitor atmospheric deposition and air pollution (in 2021, the EANET countries adopted an Annex defining monitored atmospheric environment-related substances). These monitoring sites gather high-quality data related to the deposition of major acidifying species and related chemical substances such as sulfate (SO42-), nitrate (NO3–), hydrogen (H+) in precipitation, sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and particulate matter (PM) in ambient air.

Monitoring data are used to evaluate the state of atmospheric deposition and air pollution as well as their impacts on ecosystems. Data on the atmospheric wet deposition of acidic components and other relevant pollutants have for example been used to understand the impacts of pollution on forest ecosystems, such as for the study led by EANET scientists in the dry evergreen forest of Sakaerat, in Nakhon Ratchasima Province, in northeastern Thailand.

Monitoring activities carried out in 2024 are presented in the Data Report 2024 (published in December 2025) and available in open access online.

.

High-quality Data

Over the years, EANET scientists and monitoring officers have improved the collective knowledge and skills of the Network, among others on the quality assurance and quality control (QA/QC) of the data.

The Report of the Inter-laboratory Comparison Project is conducted each year among the EANET analytical laboratories, based on the quality assurance/quality control (QA/QC) programs of the Network. The objectives of this project are to recognize the analytical precision and accuracy of the measurement in each participating laboratory, to give further opportunities to improve the quality of the analysis and to improve the reliability of analytical data through the assessment of suitable analytical methods and techniques.

.

New Face of EANET Research Portal

29 September 2021 – Niigata, Japan

EANET researchers have been working collaboratively for 20 years to study mechanisms of acid deposition and its effects on ecosystems, resulting in various scientific publications. These aim at creating a common understanding of the state of acid deposition problems in East Asia, and to provide useful inputs for decision-making at the local, national, and regional levels. Recently, an updated version of the EANET Research Portal has been released, displaying detailed information on EANET research activities.

.

20 Years of Research Activities

Why is research a central component of EANET’s activities? Since the early 2000s, collaboration on data monitoring and research has significantly improved knowledge on environmental urgencies in the region. With monitoring sites deployed in 13 countries in East Asia, scientists and researchers have access to unique data on acid deposition and air pollution.

In the decision-making process, policymakers need scientific-based evidence to guide their choices. They often use scientific results to evaluate the benefits of environmental policies and to shape government programs.

Over the years, EANET’s ability to bring together diverse players such as scientists, researchers, students, young professionals, and policymakers has made it a unique knowledge-sharing platform.

.

Sharing Scientific Outputs and Fostering Collaboration Globally

The EANET Research Portal was created to promote research activities developed in the EANET community and to enhance the use of the EANET data by the scientific community globally.

The main objectives of this page are to introduce research activities conducted by the EANET community, share scientific outputs from the EANET research activities, demonstrate the importance of the EANET data for scientific research activities, and provide opportunities for joint research activities with the EANET community.

More specifically, users can access scientific articles produced by the EANET Community, Reports of the EANET Fellowships, EANET Science Bulletins, and a database of research articles using and/or mentioning EANET data.

.

How Can Researchers Contribute to the Portal?

To expand the reach of this portal, Participating Countries are invited to share this page with their scientific peers at a national level, to link this page to their websites, and help improve its content by informing the EANET Network Center on any important paper using EANET data that might be missing from the database.
