(1) Indoor air quality work
The 111-year plan has carried out direct-reading instrument inspection operations for a total of 28 managed units and 17 non-listed units in the county. The inspection operation began in April, and the CO2 test results of the managed units were between 350 and 670ppm, and the CO2 in the non-tube field is also lower than 700ppm, and all places meet the legal
standards. And selected 7 listed or non-scheduled places with poor indoor air or special circumstances in the inspection units, and invited 2 experts and scholars related to indoor management to provide improvement measures and other methods to conduct on-site diagnosis services. Another plan is to track the achievement of the independent marks of the county's listed places and non-listed places. In 2011, 7 companies have completed the part of obtaining the excellent mark (has reached the evaluation standard). For non-scheduled establishments, the evaluation criteria will be replaced by inspections with three times the number of establishments.
(2) Operation and maintenance of air quality monitoring stations
Maintain the normal operation of air quality manual measurement stations (3 locations) and automatic measurement stations (2 locations) within the jurisdiction of the county, in order to complete the collection and release of TSP, PM10, PM2. Maintenance work; the automatic station part also completes the regular maintenance of the two stations twice a month.
1. Manual station operation and maintenance operations and monitoring results
TSP, PM10, and PM2.5 samplers in the three artificial stations are under normal operation and regular maintenance operations. As of the end of December 2011, a total of 24 regular maintenance work have been carried out, and no temporary failures have occurred and additional maintenance is required. The situation and perform multi-point calibration and maintenance on a quarterly basis. The average measured value of TSP from January to December in 111 years was 16 μg/m3, which was 24% lower than the average value of the same period last year, and 40% lower than the average value of the same period of the previous three years. The average measured value of PM101-December was 15μg/m3, which was 22% lower than the average value of the same period last year, and 32% lower than the average value of the same period of the previous three years. The average measured value of PM2.51-December is 6μg/m3, which is 26% lower than the average value of the same period last year and 40% lower than the average value of the same period of the previous three years. The dust fall in 2011 was not much different from the same period in 110, and the average dust fall in 111 from January to December was 3.4 (metric tons/square kilometer/month), which met the legal standards. On the whole, the average value of each measurement item of the manual measurement station in 111 has a trend of being lower than last year and the previous three years. According to the plan, it is judged as a project adjacent to the measurement station of the Environmental Protection Bureau (Taiwan Presbyterian Church Meilun Church 109/4/30 ~110/12/31).
(TSP annual standard value 130μg/m3, PM10 annual standard value 35μg/m3, PM2.5 annual standard value 15μg/m3)
2. Automatic station operation and maintenance and monitoring results
This year's plan calls for scheduled maintenance twice a month. As of the end of December 2011, the team has carried out 24 regular maintenance work on the monitoring equipment of the Fenglin station, and carried out the annual maintenance and calibration of the automatic station on a quarterly basis. During the implementation of this plan, the data availability rate of the Fenglin station from January to December reached an average of over 85%, and the monthly sampling data of the automatic station were submitted as scheduled. From January to December 2011, the monitoring items of SO2, NO2, CO, O3, etc. at the Fenglin Station are not much different from those at the Hualien Station of the Environmental Protection Agency. The measured value is 17μg/m3, which is 32% lower than the average value of the same period last year, and 41% lower than the average value of the same period of the previous three years. The average value of PM10 in Yuli from January to December was 13 μg/m3, which was 23% lower than the average value of the same period last year, and 13% lower than the average value of the same period of the previous three years.
(PM10 annual standard value 35μg/m3)
3. Effects and achievements of local characteristic regulation PM10 and PM2.5 related control or research work
1.. Compare the differences in the characteristics of PM2.5 particles collected at designated stations in Hualien County from January to October 2022 and 2021 under the influence of different airflow sources. Compared with 2021, the average mass concentration of PM2.5 measured without distinguishing the influence of the airflow source decreased by 1.0 μg/m3; among them, the highest decrease was 1.4 μg/m3 under the influence of high-pressure backflow; the decrease was 0.3 μg/m3 under the influence of the northeast monsoon. The m3 is the lowest; under the influence of the Pacific high pressure and the southwest airflow, both decrease by 1.0 μg/m3; under the influence of the mainland China, it increases by 1.0 μg/m3. Although the overall PM2.5 mass concentration from January to October 2022 is lower than that in 2021 , but the mass concentration of PM2.5 particles collected under the influence of airflow originating from mainland China is higher than that in 2021, which also makes the PM2.5 mass concentration decrease in the northeast monsoon type, which is easier to bring pollution from mainland China to Hualien, by less than that in 2021. Average throughout the year.
2.. Analyzing the differences in dominant species under the influence of airflow originating from mainland China from January to October 2022 and 2021, the increase of SO42- is still as high as 0.62 μg/m3, accounting for 62% of the increase in mass concentration. The estimated amount of secondary derivative particles in PM2.5 particles increased by 1.13 μg/m3, and the estimation results of water-soluble ion composition in particles were estimated by the chloride ion loss method. PM2.5 particles increased by 0.58 μg/m3 and ammonium sulfate salts. Sodium sulfate increased by 0.26 μg/m3. From January to October 2022, the impact of pollution from mainland China will be higher than in 2021, and SOX is still mainly converted into secondary derivative salts such as sulfates (ammonium sulfate and sodium sulfate) as the main source of contribution.

(3) Green landscaping and air quality purification area
In order to continue the pollution purification work, this project will assist the Hualien County Environmental Protection Bureau to continue to promote the inspection and counseling of the air quality purification area. If there are deficiencies found, the management unit will be urged to improve, and the air purification area application briefing will be held to assist in the update. Many townships and cities have applied for the establishment of air purification areas, with the goal of maintaining good air quality in the county. From January to December, a total of 144 air purification areas in the county were completed, 24 new inspections were established, 4 on-site evaluations of air purification areas were completed, 24 base adoptions were completed, 2 campus green wall constructions, and 12 carbon sinks were completed. A total of 5 bases were surveyed and subsidized for idle vacant land. In addition, the reporting unit participated in the selection activities of the Environmental Protection Agency, and the results have not yet been announced.
(4) Take a big breath
In order to cooperate with the county government's "big breath", this plan selects Taroko National Park Visitor Center, Qixingtan Recreation Area, Stone Sculpture Museum, Dongdamen Night Market Commercial District, Hualien Railway Station Commercial District, Cultural and Creative Park Golden Triangle Commercial District, Liyutan Commercial District, Qingxiuyuan, Pacific Park (the monitoring point has been changed to Zhika Xuanlu Forest Water Park since the third quarter of 2011 due to construction closure), Beibin Park, Hualien Port Fourteen popular low-carbon tourist attractions, including Landscape Bridge (the monitoring point was changed to Meilunshan Park due to construction closure in the third quarter of 2011), Meilunxi Riverside Park, New Paradise, and Lintian Mountain, will be closed every season. Carry out a simulated tourist route (walking for about 1 hour) in the "holiday daytime period" once, and use real-time particle monitoring equipment to measure PM2.5. The monitoring results of each season in 2011 are summarized as follows:
In 2011, we cooperated with the county government to carry out a comprehensive table of the PM2.5 mass concentration measurement results of low-carbon scenic spots. In the first quarter, the mass concentration of PM2.5 measured by a real-time PM2.5 measuring instrument varied between 9 and 36 μg/m3, with an average of 17 μg/m3; the PM2. The mass concentration of 5 varies between 8 and 22 μg/m3, with an average value of 14 μg/m3.
In the second quarter, the mass concentration of PM2.5 measured by a real-time PM2.5 measuring instrument varied between 8 and 17 μg/m3, with an average of 11 μg/m3; during the same period, the PM2. The mass concentration of 5 varies between 2 and 10 μg/m3, with an average value of 5 μg/m3.
In the third quarter, the mass concentration of PM2.5 measured by a real-time PM2.5 measuring instrument varied between 9 and 16 μg/m3, with an average of 12 μg/m3; during the same period, the PM2. The mass concentration of 5 varies between 4 and 13 μg/m3, with an average value of 9 μg/m3.
In the fourth quarter, the mass concentration of PM2.5 measured by a real-time PM2.5 measuring instrument fluctuated between 7 and 19 μg/m3, with an average of 13 μg/m3; during the same period, the PM2. The mass concentration of 5 varies between 2 and 13 μg/m3, with an average value of 7 μg/m3.

(6) Publicity briefings and meetings
1. Operation and management of air purification area and indoor plant publicity briefing
This meeting invites all bureaus and divisions in the county government and township and city offices to handle the establishment of relevant personnel and the existing staff of the maintenance unit of the empty product area to conduct one session on February 16, 2011. Through the briefing, we hope to encourage and supervise the villages and towns The Municipal Office is responsible for proposing the plan for setting up air purification areas and supervising and promoting the maintenance and management of existing air quality purification areas. The briefing session can also enhance the concept of what suitable indoor plants can change the air quality in the public environment, and explain The EPA subsidizes the content of the green wall program. According to the statistics, by the end of December, 2 schools have built campus green walls and 5 units have applied for greening subsidies.
2. CEMS Connection Briefing Session
The participating manufacturers included Zhonghua Pulp Mill, TCC Hualien Plant, TCC Heping Plant, Ya Cement Hualien Plant and Heping Thermal Power Plant attended the meeting. This meeting requires all industries to abide by the relevant regulations of the management measures for continuous automatic monitoring facilities of air pollutants from fixed pollution sources, so as to avoid being fined for violating laws and regulations.
3. Indoor air quality self-management publicity briefing
Invite the head of the Environmental Protection Agency to serve as a lecturer for the first batch, the second batch of announcement sites and pre-announcement sites. For establishments and units with special needs for indoor air quality, explain the audit standards, procedures, improvement methods, penalties and 111 years to promote independent management of indoor air quality, etc., and how to implement the independent management mechanism of indoor air quality so that all Units and agencies can do a good job of indoor air quality management in advance to meet the requirements of this law in the future. At the same time, discuss the common problems encountered by the Environmental Protection Bureau during the inspections over the years. According to the statistics, by the end of December, 7 establishments have completed the application for the excellent grade label.
(7) Innovative actions
In order to improve the bad situation of indoor air quality caused by formaldehyde and TVOC in the controlled places and enable the managed places to obtain the excellent grade mark and the good grade mark smoothly, and make the county's managed places feel the attention and dedication of the Environmental Protection Bureau to the managed places , in 2011, the "indoor air quality formaldehyde and TVOC counseling and testing service" was carried out for 14 of the county's first batch of managed units and 17 non-scheduled units (including kindergartens with more than 100 people), and it was divided into 3 stage executes the following instructions. The plan is to conduct site surveys according to the planned schedule, and the statistics have completed the first to third phases of operations by the end of December (investigate and record the peak hours of business hours of each listed and non-listed units, whether renovations have been carried out in the past 3 years, etc. ). According to the results of the second stage of the planned inspection, and the results of the planned investigation, the formaldehyde detection value of 17 first-batch sites and non-listed sites was higher than the standard announced by the Environmental Protection Agency by 0.08ppm. From July to July, due to the rise of the new crown pneumonia epidemic during the first testing period, each unit is an education place for children and students, and the classroom space is relatively narrow compared to the management place,In addition, the frequency of classroom cleaning and disinfection is frequent, and the gas escaped from the disinfectant is likely to remain, which affects the value of the formaldehyde concentration detected by the testing equipment. It is planned to carry out the second inspection in October, and all sites will meet the 0.08ppm formaldehyde announcement standard of the Environmental Protection Agency. It is also planned to select units whose test data are slightly close to the standard value and non-scheduled places to provide guidance from experts and scholars. After counseling and suggestions from the committee, a total of 7 units applied for the completion of the excellent label.
