Quality Assurance and Data Validation on Ozone precursor Monitoring from PAMS in 2011

Absrtact	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, and establishing a mechanism for emergency data processing to support unexpected situations. A quality assurance auditing manual was established and all audits were carried out accordingly. The field audit results did not indicate any incidents of non-conformance for the entire year. The data quality audits in each PAMS met the quality assurance criteria (85%) except for Pu Tze PAMS in June, Tainan PAMS in August, Mobile Laboratories 3 and 6 in October of 2011, respectively. System audit results indicated that the relative percent deviations of retention times for n-pentane and toluene of all stations met the quality assurance criteria of ±8%. Two compounds, cyclopentane and 1,3,5-trimethylbenzene were tentatively added to the list this year. Once enough data are collected and evaluated, these compounds will be on the official list for monitoring. Annual performance check results indicated that all stations met the quality control criteria of ±25% (including toluene and styrene) except in Chao Tou station. A mechanism was established to initiate emergency data processing mainly to respond to photochemical incidents or other unexpected situations. In case of such an incident, data processing personnel will coordinate with Environmental Protection Administration (EPA) staff in the collection, processing and analysis of the PAMS data (including mobile laboratories) in order to clarify the problem. Once the station’s maintenance unit is notified or has found anomalies, the emergency response personnel should immediately inform the data processing team, send the appropriate field personnel to correct the problem, and report to the contact person in the Department of Environmental Monitoring and Information Management of EPA, who should send the report up the chain of command.
