While this is acceptable for determining a maximum potential exposure or 
identifying the extent of

assessing the potential impact of any future abatement strategies or determining 
the level of exposure outside the vicinity. This paper presents an approach in 
which representative air quality assessments can be undertaken for an urban area 
using the

measurement sites. A novel methodology is described that involves site selection 
to capture the maximum variance in measured pollutants, while minimizing 
spatiotemporal autocorrelation between the selected sites. A case study is 
presented for Yazd, Iran. Overall, the results show that the proposed 
methodology can be effective and enable the long-term monitoring of air 
pollution to be undertaken on a cost-

addition, there is the potential for the methodology to be utilized for other 
forms of pollution (e.g., water, soil, and noise).[PUBLICATION ABSTRACT]In this 
study, the concentrations of CO, non-methane hydrocarbons, NO^sub X^, SO^sub 2^, 
benzene, toluene, ethylbenzene, xylene (BTEX), PM^sub 10^, and PM^sub 2.5^ were 
continuously monitored before and after the fireworks display during the 
traditional Lantern Festival from March 2-7, 2007 in Yanshui Town, Taiwan. Major 
Christian 
Louboutin Tall Platform Boots Black 13 in Yanshui Town were 
surrounded by fireworks 13 km in length, with the display lasting for 45 min. 
More than 200 small firecracker towers popped up randomly in town, resulting in 
exceedingly inhomogeneous air quality until the end of display at 03:00 the next 
day, March 5. During the fireworks display, the hourly concentration of PM^sub 
10^ and PM^sub 2.5^ at Yanshui Primary School reached about 429 and 250 μg m^sup 
-3^, respectively, which is 10 times the normal level, and 6 s values even went 
as high as 1,046 and 842 μg m^sup -3^, respectively. Similarly, BTEX 
concentration went up to about five to 10 times its normal value during the 
fireworks display. As indicated by the distribution of submicron particle sizes, 
the number of particles with a diameter less than 100 nm increased abruptly 
during the event period. Metal components with concentrations of more than 10 
times higher than the normal value at Yanshui Primary School were Sr, K, Ba, Pb, 
Al, Mg, and Cu, in sequence. Among water-soluble ions, the content of K^sup +^, 
Mg^sup 2+^, and Cl^sup -^ increased the most, all of which were related to the 
materials used in the fireworks.
