Pairoj Rattanangkul checks black smoke and noise pollution for Khao Yai National Park’s vehicles

Khao Yai National Park, the Department of National Parks, Wildlife and Plant Conservation has carried out a prototype project to enhance the environmental quality affected by air and noise vehicles. In order to integrate with similar duty agencies, namely, Acoustics and Vibration Group National Institute of Metrology (NIMT), Pollution Control Department (PCD), and the Regional Environment Office 11 Nakhon Ratchasima jointly organized activities at Khao Yai National Park on 7-8 July 2022.

For this matter, Head of Khao Yai National Park Mr. Chaiya Huayhongthong assigned to Assistant Head of Khao Yai National Park Mr. Termsak Noinarai and his officers welcomed Group leader of Acoustics and Vibration Mr.Pairoj Rattanangkul, NIMT metrologists and PCD officers.

Mr.Tersak led 135 national park vehicles to check for black smoke and noise measurements by NIMT and PCD. It is a pilot and prototype project to reduce the environmental impact from the vehicles to screen them before entering the conservation area which is a standard ecotourism place in order to reduce the impact on the quality of life of wildlife Tourism. The project is called the “Government Cars reduce Pollution” project which encourages the use of government vehicles by not-supporting air and noise emissions lower than the standards criteria. It corresponds to the plan of action on resolving the pollution of PM2.5 caused by incomplete combustion. The project runs under the research physical property in the metrology of the cheapest noise meters that comply with the standards and function to vehicle noise meters.

NIMT and Pollution Control Department (PCD) signs a Memorandum of Understanding (MoU)

Mrs.Ajchara Chareonsook, Director of NIMT Ministry of Higher Education, Science, Research and Innovation (MHESI) and Mr. Pralong Dumrongthai, Director General of Pollution Control Department (PCD) Ministry of Natural Resources and Environment (MNRE) signed a MOU to collaborate together in the field of metrology at PCD on 30 July 2020.

It would be beneficial to various organizations to take action where they are working relevant with the Environmental Issue Management and Emission Testing for Stationary Sources. With this MOU, we will be able to set one standard nationwide and utilize it to create new innovation to ensure our measurement system is relying to national and international standards.

For this reason, there are four parts of cooperation consisting of 1) Air Quality Measurement 2) Emission Testing for Stationary Sources 3) Water Quality Measurement, and 4) Sound Level Measurement.

NIMT will support the mission of PCD that is essential to use an accurate scientific device and data or example collection method because the accurate method affects measurement’s accuracy and credibility on pollution level measurement and investigation. Therefore, it will be able to evaluate severe environmental issue situations. Thus, its achievements are parted to four levels; 1) measurement and calibration instrument development, and measurement credibility building 2) measurement method development 3) measurement method and action establishment ,and 4) measurement potential staff development
