Ambient Air Quality Monitoring Plan in year 2017

Absrtact	This project has started since November 11th, 2017. The project scope included ●operation, maintenance and calibration of equipment at Air Quality Monitoring Station and renewal of the equipment of one station; ●noise monitoring and case handling; ●mobile van monitoring; ●maintenance of PM2.5 continuous monitoring stations; ●maintenance of equipment at meteorological stations; ●update and maintenance of digital signage; ●functional audits of stations in offshore industrial park; ●maintenance of acid rain stations and setting up simple Air Quality Monitoring network. The achievements of project were summarized as below: 1)60 Air Quality Monitoring Station were performed scheduled monthly maintenance and 120 TSP samples had been completed. 2)Flow rate calibrations were completed on 2nd January 2018. The result regression coefficient was 0.9999 which comply with the standard. (The regression coefficient shall be larger to 0.999) 3)Multi-point calibrations were performed on 10 January 2018, 11 April 2018, 5 July 2018 and 3 October 2018. The results were fulfill with the standard requirements including flow accuracy shall be less than 5 % difference and regression coefficient shall be larger to 0.995. 4)Every half of the month, one point calibrations were performed before and after sampling at each station. The flow accuracy shall be less than 7% difference. 5)TSP：The highest(57μg/m3) geometric average concentration were found at Huwei station and Beigang station. And the lowest(42μg/m3) geometric average concentration were found at Gukeng station.The monitoring results at all stations met the air quality standards(TSP 24 hour 250 μg/m3). The geometric mean over the years were below the air quality standards(130 μg/m3), and since 2013, there was a gradual downward trend. 6)Dustfall：The highest(2.92 ton/km2/month) and lowest(1.29 ton/km2/month) average concentration were found at Hsilo station and Gukeng station. In the annual average, the average annual measured value was the lowest in 2017 at 2.54 ton/km2/month and the highest in 2015 at 14.05 ton/km2/month. The average measured value in 2016 was 6.02 ton/km2/month, showing a decreasing trend compared with the monitoring results in recent years. 7)Compared with the corresponding sections of neighboring counties (Taichung, Changhua, Nantou, Chiayi, Tainan, Kaohsiung and Pingtung), the trends of TSP in all counties and cities were approximately the same, but the Kaohsiung City had a higher tendency than other counties and cities. Among the monthly averages, Kaohsiung City had the highest value of 112 μg/m3 in December 2017. The lowest value of 13 μg/m3 in Yunlin County (August 2018) and 18 μg/m3 in Changhua County (June 2018). The Dustfall in counties and cities did not have the same trend. The highest was 30.40 ton/km2/month (December 2017) in Kaohsiung City and the lowest was 0.12 ton/km2/month (June 2018) in Changhua County 8)The equipment of one Air Quality Monitoring Station had renewed, including high volume samplers, voltage regulators and dust sampling platform. 9)Ambient and traffic noise monitoring have been performed 80 days and all results fulfilled the limit. According to historical monitoring data, in ambient noise monitoring was easier to detect high values. In traffic noise monitoring, monitoring values were more concentrated because they were less disturbed by external factors. 10)12 times maintenances were completed at fixed noise monitoring station. The sources of noise were proposed. During weekdays, the noise would be come from high flow of vehicles at peak periods and operation of machine during gardening. During the weekend, the sources would be park visitors and temporary exhibitions. 11)Checking of noise level from vehicles has been performed 42 times and checked 1,407 vehicles. 44 vehicles were requested to perform further noise assessment in which 20 vehicles passed, 10 vehicles unqualified and 14 vehicles unclassified. Among vehicles that can't be inspected on site due to factors such as lack of vehicle information or bad condition on the spot will be notified to the inspection. As selection by police before further assessment, the rate of unqualified was reach 33 % and average exceed 3.87 dB of limit. 12)Completed measurement of non-ionizing electromagnetic radiations of 1 mobile phone platform during which 0.0044 mW/cm2 was the highest result recorded, and 39 ultra-low frequency floor-type transformers with 7.417mG and 1.651mG recorded as the highest and lowest frequencies. Results were way below the suggested non-ionizing electromagnetic radiations values (0.455mW/cm2 in radio frequency and 833mG in ultra-low frequency) under the EPA Notice. 13)Had completed two sets of electronic firecracker purchase and delivery. 14)Completed 12-day mobile van air quality monitoring in Douliu Industrial Park and surrounding area of Yunlin Technology-based Industrial Park. All measurements complied with the air quality objective of 8-hourly average of ozone emission except the measurements from 30 Apr, 2018 to 1 May, 2018 and 15 Oct, 2018 to 16 Oct, 2018 at Fudegong, Meilin. Measurements under the same period of time at Douliu station also exceeded the limit, during which 69.0ppb and 65.3ppb were the highest values measured respectively in the two periods, indicating a widespread deterioration of air quality. 15)Completed the maintenance works of 24 PM2.5 continuous monitoring stations. The stations are in good conditions, and monitoring is kept going. 16)Completed maintenance works of equipment at 60 meteorological stations. Standby wind sensors are being used at Sin-sing Elementary School and Liuhing Nanmen, and standby carbon dioxide detectors are being used at Sin-sing Elementary School, Liuhing Nanmen and Siyi Activity Centre. 17)Completed connection system update for 1 LED digital signage, and implemented 12-time monthly maintenance on digital signage. 81 updates on broadcasting content had been completed. 18)Completed functional audits for 2 stations (Tungshih Station ＆ Tuku Station) in offshore industrial park. Audit results were satisfactory. 19)Completed 26 times bi-weekly maintenance, 12 times monthly maintenance and 4 times quarterly maintenance for acid rain stations. 20)Completed building of 32 simple air quality monitoring stations and 2 sets of anemometers in Douliu Industrial Park, and 9 monitoring works had been completed by far. All works are being carried out in accordance with schedule.
