Abstract

This work studies O-3 pollution for Chon Buri city in the eastern region
of Thailand, where O-3 has become an increased and serious concern in
the last decade. It includes emission estimation and photochemical box
modeling in support of investigating the underlying nature of O-3
formation over the city and the roles of precursors emitted from
sources. The year 2006 was considered and two single-day episodes
(January 29 and February 14) were chosen for simulations. It was found
that, in the city, the industrial sector is the largest emissions
contributor for every O-3 precursor (i.e., NOx, non-methane volatile
organic compounds or NMVOC, and CO), followed by on-road mobile group.
Fugitive NMVOC is relatively large, emitted mainly from oil refineries
and tank farms. Simulated results acceptably agree with observations for
daily maximum O-3 level in both episodes and evidently indicate the
VOC-sensitive regime for O-3 formation. This regime is also
substantiated by morning NMVOC/NOx ratios observed in the city. The
corresponding O-3 isopleth diagrams suggest NMVOC control alone to lower
elevated O-3. In seeking a potential O-3 control strategy for the city,
a combination of brute-force sensitivity tests, an experimental design,
statistical modeling, and cost optimization was employed. A number of
emission subgroups were found to significantly contribute to O-3
formation, based on the February 14 episode, for example, oil refinery
(fugitive), tank farm (fugitive), passenger car (gasoline), and
motorcycle (gasoline). But the cost-effective strategy suggests control
only on the first two subgroups to meet the standard. The cost of
implementing the strategy was estimated and found to be small (only
0.2%) compared to the gross provincial product generated by the entire
province where the city is located within. These findings could be
useful as a needed guideline to support O-3 management for the city.
Implications: Elevated O-3 in the urban and industrial city of Chon Buri
needs better understanding of the problem and technical guidelines for
its management. With a city-specific emission inventory and air quality
modeling, O-3 formation was found to be VOC sensitive, and a
cost-effective control strategy developed highlights fugitive emissions
from the industrial sector to be controlled.
