Volatile Organic Compounds (VOCs) in Ambient Air Standards of Thailand

Remark

: 1.

One year Volatile Organic Compounds (VOCs) in Ambient Air is determined from the Arithemetic Mean of VOCs analysis from continuously 24 hour ambient air sampling (at least once a month)

2.

In case of the collected ambient air sample(s) was unable to be analysed, the new sampling and analysis must be done within 30 days from the previous sampling date.

3.

Reference Condition is 25 degree Celsius at 1 atm or 760 mmHg

Ambient Air Quality Monitoring Networks

One of the most important components in an air quality

management program;

Under the Enhancement and Conservation of National

Environmental Quality Act of 1992, PCD is responsible for

monitoring air quality in Thailand and subsequently

preparing an annual report on the state of air quality of the

country;

The ambient air monitoring data is used as an essential

precursor to some form of control activities;

History1981: The National Primary Ambient Air Quality Standards were promulgated

1983: The first air quality monitoring system was installed 8 stations in BKK (not on-line system)

1987: The first on-line and real-time continuous air quality monitoring system was installed 5 stations in Samut Prakarn (JICA’s assistance)

1991: The third monitoring system (an on-line and real-time continuous system) 4 stations on the curb-sides of streets in BKK

1992: PCD with the technical assistance from the Swedish Gov. started preparing the design of a nation-wide ambient air quality monitoring networkand a meteorological monitoring network

1996: The networks were gradually put in several phases through the upgrade of the existing air quality monitoring stations and the installation of new ones;

Overall Policy

Control and reduction of emissions from key sources, i.e. On-road vehicles, industry, construction, and field open burning

Management of area-wise air pollution taking the concept of carrying/ assimilating capacity

Enhance capacity of local environmental agency

in monitoring environmental quality and status of

emission sources

Development and update the emission database

in critical area

Promote Clean Technology and Cleaner Fuel

Overall Policy (continued)

Enhance annual vehicle inspection programme

Enhance public participation in air pollution management

Implement measures for controlling open burning and developing the monitoring and early warning system for air pollution and haze forecast

Overall Policy (continued)

Mobile Emission ControlEmission Reduction from New VehicleEmission Reduction from In-use VehicleFuel Quality ImprovementAlternative FuelProject of emission measurement from vehicle used gasoholChallenge Ahead

Challenges AheadImproving air quality management VS Fuel ReformulationLocal, national and international cooperation ; more involvement from relating organizations is neededFrom strategy to real-world implementationStrategies need to be accompanied by sustainable incentive packagesAction taken to tackle air pollution could also compensate benefits to all sections
