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, assessing the suitability of the locations for the monitoring stations and submitting the proposal for proper station adjustment.
The quality assurance auditing manual was revised and all audits were carried out accordingly. The field audit results are complete; the deficiencies have improved. The data quality audits in each PAMS met the quality assurance criteria (90%) except for Wan Hua PAMS in October, Tu Cheng PAMS in October, Tai Hsi PAMS in January, September and December, Pu Tze PAMS in February, Tainan PAMS in October, Chau Jou PAMS in May, August and September, and Mobile laboratory 5 in August, September and October of 2014, Zhong ming PAMS in February, Pu Tze PAMS in May, Tainan PAMS in June, Xiao gang PAMS in June, July, September and October, Chau Jou PAMS in December, Mobile laboratory 5 in March, May, June, August, September and October, Mobile laboratory 6 in April and October for 2015, respectively. System audit results indicated that the relative percent deviations of retention times for n-Pentane, Toluene, Cyclopentane and 1,3,5-Trimethylbenzene of all stations met the quality assurance criteria of ±5% for 2014 and 2015. The absolute retention time differences for all the above compounds were less than one minute which met the requirement as well. The annual performance check results indicated a few compounds, such as Ethylbenzene and Styrene, were found to exceed the ±25% limit for Tainan PAMS and Mobile laboratory 5. Most of the other PAMS analyses met the quality assurance criteria. Tainan PAMS started using a new standard gas 103 in November, standard gas purchases of 2015 will give priority to replacing that used in Mobile laboratory 5, the annual performance check results indicated that all stations met the quality control criteria of ±25% for 2015.
The comprehensive review of the results for all PAMS indicated that Wan Hua, Tu Cheng and Chau Jou PAMS’ were not as effective at meeting the monitoring objectives as the other stations were. It is suggested that if any PAMS are to be relocated, Tao Yuan County should be considered high priority. Tao Yuan County has the largest number of technology companies in Taiwan. The possible monitoring targets of the station in the county include the Industrial Parks of Ministry of Economic Affairs and Industrial Parks developed by private sector or by urban planning renovation. The station could also serve as a tool to monitor vehicular pollutants.
