Combating Air Pollution in Thailand: A Collaborative Project to Enhance PM Measurement

Air pollution is a significant global threat, claiming millions of lives annually. Recognizing this urgency, the National Institute of Metrology (Thailand) (NIMT) has embarked on a crucial project: PM10 and PM2.5 from Haze Smog and Visibility Effect in Thailand. This initiative aims to establish a laboratory dedicated to measuring particulate matter in Thailand.

The project encompasses several key activities:

·  Online and In-Person Training: NIMT metrologists received online coaching from renowned experts from the National Institute of Metrology, China (NIM).

·  In-Depth Exploration of PM Measurement: Throughout 2023, NIMT metrologists engaged in extensive study visits and joint research at NIM on diverse aspects of PM measurement. This included investigating the effects of humidity, calibrating particle size, validating and calibrating PM2.5 devices, and establishing traceability chains for both PM2.5 and PM10 measurements.

·  Knowledge Sharing and Collaboration: In 2023, a seminar was held in Thailand. The project team, along with the experts from NIM, shared their expertise with participants from Lancang-Mekong Cooperation countries. Furthermore, two NIM experts visited NIMT Thailand, fostering knowledge exchange and capacity building.

·  Technology Transfer and Expertise: Two NIMT metrologists were invited as experts (consultants) for the 2023 AIRLAB Microsensors Challenge Project conducted by Airparif (France). This valuable experience allows them to transfer knowledge and contribute to air quality monitoring efforts in Thailand through the Pollution Control Department.

By undertaking these comprehensive initiatives, it is making significant strides towards enhancing air quality monitoring capabilities in Thailand. This project not only benefits Thailand but also fosters regional collaboration in addressing the critical issue of air pollution.
