The project of “Air Quality Monitoring Site Operation and Maintenance in Taoyuan Country of 2009” aims at five automatic continuing monitoring sites, which are locating in Sam-Ming park, Lu-Chu elementary school, Ne-Li senior high school, Sin-Sing elementary school, Guane-Ine industrial area, the other sites are seven artificial sites including in Da-yuan industrial area, Gui-Shan industrial area, Yun-Mei library, Chung-Li examine department, Taoyuan-Ron school, Lu-Chu sanitation clinic, Nei-Din elementary school. In order to make sure that both reliability of data and stability of instruments, various monitoring stations carry on the work of routine maintenance according to the standard procedure, example for weekly-twice maintenance, monthly maintenance, seasonal maintenance and yearly maintenance along with non-periodical trouble shooting and the recovery service, it is important to keep this project normally work. During this annual period, there are instruments functional checks and the survey station achievements checks and so on the improvement work for guaranteeing the instruments proceeding normally and preventing the flaw occurrence.
This annual project for each station monitor results, the carbon monoxide (CO) stands highest as 0.86ppm of Sam-Ming site(traffic site) in all, for ambient monitoring sites stands high as 0.73ppm of Ne-Li site, lowest for 0.60ppm of Lu-Chu site; the sulfur dioxide(SO2) monitor result by the industrial station of Guane-Ine site measured the highest value(9.3ppb), the ambient ones stands high as 7.8ppb of Lu-Chu site, and the lowest for 5.0ppb for Sin-Sing sites. Other regional pollutant as ozone(O3) and suspended particulate matter(PM10) vary closely for each sites. Guane-Ine site measured highest its PM10 as 85μg/m3, O3 as 25.8ppb, lowest value obtained PM10 is 47μg/m3 of Sam-Ming site, the O3 is 22.5ppb on Lu-Chu site. The artificial sites demonstrate monitoring results and ingredient analyses, TSP is 85μg/m3, the sulfate is 17.6μg/m3, the nitrate is 8.71μg/m3, fall-dust is 17.7 ton/km2/month, these value stands for highest of Gui-Shan site; The closed offshore Da-yuan site stands chlorine salt as 4.32μg/m3 for highest, and high traffic flow near Chung-Li site has the lead as 0.447μg/m3 for highest value.
The project of this year uses the instruments to have 70% at present all to surpass the service life. If appraised by the instruments condition, then there is 76% to be in the normal operation, 17% belongs serviceable, and 7% instrumentation equipment to suggest in addition selects exchanges old. What suggested to exchange includes in THC analyzer and PM10 monitoring apparatus for Sin-Sing, Ne-Li, and Sam-Ming sites.
