(1) Indoor air quality operations
There are 30 first and second batches of site inspections in February, and some sites have exceeded the standard during peak hours, which are caused by poor ventilation or large crowds. The plan has been announced and provided for many years. Relevant information is for the reference of the place. In the autonomous management part, the place can respond to the contingency measures when the indoor empty product is bad. In addition, we conducted investigation and counseling work on floor area, number of people in and out, and indoor air-conditioning for non-listed places, including parent-child pavilion, baby care center, sightseeing factory, underground parking lot, and non-listed gym in this county, and the survey results have been uploaded To the EPA web platform. At the same time, according to the inspection of the 30 listed places, 5 places will be conducted on September 20 for experts and scholars to provide guidance and advice on improving the place.
(2) Operation and maintenance of air quality monitoring station
Maintain the normal operation of the air quality manual measurement stations (3 places) and automatic measurement stations (2 places) within the jurisdiction of the county to complete the collection and placement of TSP, PM10, PM2.5, and dust in the three manual stations twice a month Maintenance work; the automatic measuring station part also completes the regular maintenance of the two stations twice a month, and the data availability rate is more than 96%.
1. Operation and maintenance operations and monitoring results of manual stations
The TSP, PM10, and PM2.5 samplers in the three manual stations under normal operation and regular maintenance operations have performed a total of 24 regular maintenance operations as of the end of December 108. No temporary faults have occurred and additional maintenance is required. And perform multi-point calibration and maintenance on a quarterly basis. The 108-year manual survey station TSP had an average value of 30 μg / m3 from January to December, which was 5% lower than the average of the first three years. The average measured value of PM101 in December was 24μg / m3, which was an increase of 8% compared with the average of the first three years. The average value of PM2.5 from December to December was 11 μg / m3, which was an increase of 6% compared with the average of the first three years. The amount of dust falling in 108 years has not changed much from that in 107 years. The average amount of dust falling from January to December in 108 was 3.7 (metric tons per square kilometer per month) in compliance with regulatory standards. (Dustfall water samples in October due to mistakes made by logistics companies during the delivery process, resulting in no dustfall data this month).
2. Operation and maintenance operations and monitoring results of automatic stations
This year's plan requires two regular maintenances per month. As of the end of December 108, the team conducted a total of 24 regular maintenance work on the monitoring equipment of Fenglin Station, and performed annual maintenance and calibration of the automatic station on a quarterly basis. During the implementation of this project, the data availability of Fenglin Station from January to December averaged 96%, and the monthly sampling data of the automatic station was completed as scheduled. The monitoring items SO2, NO2, CO, O3 and other monitoring items of Feng 林 station from January to December in 108 are shown to be not much different from the previous years. In addition, the average measurement value at PM10 108 年 from January to December in Feng 林 is 34μg / m3, an increase of 23% compared with the average of the first three 年.
3. Effectiveness of local characteristics control and related PM10 and PM2.5 related control or research work
Sampling results of PM10 and PM2.5 on the Taiwan-Kowloon Line: PM10 was 12 μg / m3, PM2.5 was 7 μg / m3, and PM2.5-10 was 5 μg / m3 when the characteristics of traffic pollution sources were measured on the sidewalk of the front line of Dahan Technical College. The measured PM2.5 / PM10 ratio is 0.61, which is higher than the ratio of 0.47 at the Hualien Kongpin Station during the same period, which should be caused by PM2.5 contribution to traffic pollution sources.
Estimated sources of PM2.5 traffic pollution sources: secondary-derived particulates accounted for 43%, traffic pollution sources accounted for 30%, sea salt-related ions accounted for 5%, non-sea salt-derived Ca2 + and Mg2 + (dust-related) accounted for 2%, not The appraisal accounted for 20%. In the same period, the proportion of PM2.5 particles at the Dahan Station, which is 4 stories high, originated from traffic pollution sources was 17%. It shows that traffic pollution sources still contribute to PM2.5 particles.
Correlation analysis between species: the correlation coefficient R of PM2.5 particle mass concentration and SO42- and NH4 + in the particles is as high as 0.93 and 0.93, showing the variation of the leading particle concentration of derivative particles. The PM10 particle mass concentration and the correlation coefficient R of SO42- and NH4 + in the particles reached 0.87 and 0.86; the correlation coefficient R of the NO3-, Ca2 + and Mg2 + reached 0.82, 0.88 and 0.89, inferring that the traffic dust caused by traffic pollution sources is not negligible Contribution source.
Correlation analysis with vehicle flow composition: the correlation between the particle mass concentration and the vehicle flow composition is not high. The PM10 and PM2.5 particle mass concentrations collected by the Taijiu Line meet the air quality standards, and the impact of traffic pollution is still at an acceptable level .
