The achievements of this annual project are stated as below:
For Chencily Auto-Monitoring Station, the data obtaining rates of the analyzers were all above 91%, whereas those of the meteorological equipments were above 98%. For the PM10 monitoring reports, Chencily, EPA Tainan and EPA Annan stations showed the significant season influences on PM10. The readings in summer were obviously lower than those in winter and the trends of the three Stations were identical. During the project period, from February 2006 to January 2007, PM10 counted for 22 episode days in total: 8 days at Annan station, 7 days at both Tainan station and Chencily station. The highest value reached 207μg/m3. For the ozone (O3) monitoring reports, Chencily, EPA Tainan and EPA Annan stations had similar readings and the trends were also identical. During the project period, O3 counted for 40 episode days. Among them, Tainan station had the most of 22 days, Annan station stood at the second with 10 days, and Chencily station had the least of 8 days. The highest value reached 81.6ppb and mostly happened in summer, which showed the impact of sunshine. NOX and NMHC are the two major factors that form ozone (O3). Since they are mainly from the discharge of motor vehicle and motorcycle, it explains why Tainan station, which locates in urban area, had the most episode days.
The TSP results at the Manual Operation Monitoring Stations were complied with the air quality standard. From year 1998 to 2007, TSP values have been showing an identical trend, high in winter and low in summer. As for the analysis of TSP constituents, the concentration of n-Hexane extract was between 0.36~6.85μg/m3. During those years, the highest of 7.91μg/m3 occurred in 1999 and the lowest of 3.26μg/m3 did in 2006. The concentration of Cl- was between 2.04~21.38μg/m3. The trends were identical, slightly higher in winter. The highest of 14.56μg/m3 occurred in 2004 and the lowest of 4.3μg/m3 did in 1998. The concentration of NO3- in TSP constituents was between 3.01~14.60μg/m3. The measurements over the past years showed a trend of high in winder and low in summer. The highest of 15.42μg/m3 occurred in 2001 and the lowest one of 4.73μg/m3 did in 1998. The concentration of SO42- in TSP constituents was between 4.82~23.73μg/m3. The highest of 20.39μg/m3 occurred in 1999 and the lowest of 11.23μg/m3 did in 2005. The concentration of Pb in TSP constituents was between 0.016~0.056μg/m3. The highest of 0.526μg/m3 occurred in 1998 and the lowest of 0.030μg/m3 did in 2005. The measurements of all stations were below the monthly mean (1.0 μg/m3) in accordance with the air quality standard.
The trends of dust fall at the Manual Operation Monitoring Stations were all similar. In the past years, the highest value was 11.69 tons/square km/month in 2004 and the lowest value was 4.23 tons/square km/month in 2001.
EPA inspection report showed that Chencily Auto-Monitoring Station achieved 89% in the satisfaction survey. Two flaws were pointed out and improved on the day of inspection. The stations at South District Office and Tainan Municipal Min-De Junior High School were selected for the inspection of Manual Operation Monitoring Station. The outcome was 100% satisfactory.
For the electronic billboard, a total of 197 advertisements were broadcasting. Among them, 148 were for Tainan EPB, which counts for 75.13%; 37 were for the Revenue Service Office; the rest was for Tainan City Government, National Tax Administration, etc. It certainly has provided an effective way to publicize the environmental protection policies.
