AIR-SATREPS Researchers Present at ICFEE 2026

Three researchers from the AIR-SATREPS Platform participated in the International Conference on Future Environment and Energy 2026, held on 6–8 March 2026 in Fukuoka, Japan, to share their latest research on air quality in Cambodia.

Our researchers' presentations included:
Dr. Phat Chanvorleak – Polycyclic aromatic hydrocarbon exposure during commuting: a comparative analysis of bus and tuk-tuk in Phnom Penh
Mrs. Sieng Sreyvich – Carbonaceous components in airborne nanoparticles (PM0.1) during the dry season in the urban area of Phnom Penh City, Cambodia
Ms. Doeurn Seyha – Seasonal characteristics of gaseous air pollutants in Phnom Penh, Cambodia

🎉 We are also proud to share that Ms. Doeurn Seyha received the Best Presentation Award at the conference.
Their participation highlights ongoing efforts of the AIR-SATREPS Platform to advance air pollution research and strengthen international scientific collaboration.

Air SATREPS Platform Focus Seminar with Waseda University

As part of the Air SATREPS Platform activities, a focus seminar was held featuring researchers from Waseda University to promote knowledge exchange in atmospheric science.

The seminar included presentations by Ms. Matsumi Ohama on atmospheric aerosols and VOCs in Siem Reap and Phnom Penh, Prof. Hiroshi Hayami on atmospheric conservation and altitude-specific observations, and a special invited talk by Prof. Hiroshi Okochi on airborne microplastics, including recent findings from Siem Reap and Tonle Sap Lake.

We sincerely thank the speakers for sharing their valuable insights and for supporting knowledge exchange with students and researchers in Cambodia.

🌫 Haze Condition: What You Should Know

Haze condition is a phenomenon that reduces atmosphere visibility and affect our health, that happens mostly during dry seasons. Understanding its causes and how to protect ourselves helps lower health risks for our communities.

AIR-SATREPS project continues to contribute to air quality research and raise awareness to support cleaner air for everyone in Cambodia. Together for clean air!

"

We were pleased to welcome Associate Professor Tomoki Nakayama (Nagasaki University), the developer of the Low-Cost Sensors (LCS) used in our project, to the Institute of Technology of Cambodia (ITC), together with Professor Hata and Professor Ikemori.

During the visit, Prof. Nakayama kindly conducted an LCS workshop, which greatly deepened our understanding of the sensor technology and its application in air quality monitoring.
The team also visited actual LCS installation sites to review the on-site setup and conditions.

The visit was extremely valuable for strengthening technical knowledge and collaboration within the project.
We sincerely appreciate the time and support, and look forward to welcoming you again on your next visit to Cambodia.

✨ SATREPS × EANET Joint Training Completed! ✨

From 1–5 December 2025, SATREPS members from Cambodia joined the PM2.5 Source Apportionment Training held onsite at ACAP (Asia Center for Air Pollution Research) in Niigata, Japan.
https://www.acap.asia/en/4886/

This training was implemented under the collaboration between SATREPS and EANET Project 2025-01

They were accompanied by Professor Mitsuhiko Hata from Kanazawa University and Associate Professor Fumikazu Ikemori from Nagasaki University, strengthening the scientific collaboration between Cambodia and Japan.
Throughout the week, participants learned practical skills in PM2.5 measurement, chemical component analysis, and PMF-based source apportionment.

This training served as an important step in enhancing
🌏 international collaboration among Cambodia, Japan, and the broader East Asian scientific community,
and contributes directly to building Cambodia’s scientific foundation for future air quality management.

🌏 AIR-SATREPS at the 2025 Blue Skies & Net Zero 2050 Annual Event 🌿

On October 16, 2025, the AIR-SATREPS Project was honored to take part in the 2025 Annual Event of the Blue Skies & Net Zero 2050 Campaign, organized by the Ministry of Environment, GGGI Cambodia, and ITC under the theme “Smart Steps for Clean Air: Innovation, Youth, and Action for 2050.”

The event highlighted Cambodia’s efforts to achieve net-zero greenhouse gas emissions through waste management and air quality improvement. AIR-SATREPS contributed by showcasing their ongoing research on air pollution sources, seasonal patterns, and the environmental impacts of waste burning.

As part of the Science Walk, participants visited Cambodia’s new air pollution management platform: the air quality monitoring stations along with the air quality laboratory established and equipped with support from Japan Internation Cooperation Agency (JICA) and Japan, Science and Technology Agency (JST) under the SATREPS program.

During the event, H.E. Dr. Eang Sophalleth, Minister of Environment, emphasized that “the participation of all stakeholders in Cambodian society can help clean blue skies and transform Cambodia into a carbon-neutral country by 2050.”

Through science and continued collaboration, the AIR-SATREPS Project remains committed to building knowledge, enhancing research capacity, and supporting science-based policymaking toward clean air and carbon neutral goal in 2050.
