The main objectives of this program included implementing the quality assurance audits of analytical systems for Photochemical Assessment Monitoring Stations (PAMS), standardizing the data processing procedures for the collected results, characterizing the local pollutant profiles of different areas, evaluating the effectiveness of the operation, the appropriateness of the current sites for PAMS, and suggesting future sites for new monitoring systems.
A quality assurance auditing manual was established and all the field audits were carried out accordingly. The incidents of non-conformance mostly consisted of incomplete records in the first half-year. The non-conformance was corrected accordingly for the rest of the year. The data quality audits in each PAMS met the quality assurance criteria (85%) except for Tainan PAMS in February and March, and Chiau Jou PAMS in March and August of 2010, respectively. Analytical system audits for the response factors indicated that the standard deviations for n-Pentane exceeded the quality assurance criteria ±8% once in Wan Hua, Tainan, Chiau Jou and mobile laboratory 3, respectively. The standard deviations for Toluene were also found to exceed the quality assurance criteria ±10% once in Pu tze and mobile laboratory 3, respectively. The yearly performance evaluation result indicated that all analytes met the quality assurance criteria ±25% for Pu tze, Chao Tou and mobile laboratory 5. A few compounds, such as Toluene, n-Pentane, Isoprene, n-Dodecane and Styrene, were found to exceed the ±25% limits in other PAMS. Most of the other analytes met the quality assurance criteria.
According the statistics of the historical data, it is found that the stations in Tainan and Chiau Jou did not provide a distinct effect. We therefore suggest relocating a station in Jen Wu. A PAMS in this location can be useful in the monitoring of China Petroleum Corp., Jen Wu and Da Sir industrial district as well as the exhaust from the heavy traffic in the area. We also suggest that some monitoring stations be established for background data collection in the upwind locations, such as Wan Li in North and Hen Tsun in South, according to the seasonal wind directions.
