This project carrying out two major scopes, one for the air quality management development project (hereinafter referred to as SIP) to enhance Penghu County to improve the air quality and control the working quality of each sub-project and developing the control measures base on the air quality level, the other is to analyzise the source of PM2.5 and develop the improvement strategies.
1. Achievements in SIP
(1)In Penghu County, according to data of EPA Air Quality Automatic Monitor Stations, the level of PSI 50 is 158 days (43.2%) form Janeray to December at 2013, 51 PSI 100 is 207 days (56.7%), there is no significant difference between last year, only the EPA Published alert at November and December the PSI 100 is 5 days, and the average PSI is 79~86, in accordance with the deterioration of air quality contingency measures, project group published the LED, press releases and messages in time, remind peoples to avoid outdoor activities.
(2)Comparing PSI in the past years, the most content is ozone and TSP, the ratio of each is 56.46% and 43.54%, indicate that the component in PSI of Penghu County is TSP became ozone, it’s also mean that the TSP, SO2, NO2, ...etc. are declining these years. And over 67% people are approve of the air quality in Penghu County.In addition to increase the control of TSP continuously, the precursor for ozone are also the most important issue in the future.
(3)To assist EPA to accomplish the assessment, including each sub-project implementations integration, such as idling stop, refueling autostop, gasoline recovery, outdoor combustion, and air quality purification areas promotion, ... etc.,total of 17 activities, and EPA quarterly, and also according to the pollution control plan of 2013, all the work item are accomplished and meet the target. Proposed "to maintain the existing good air quality, reduce pollution emissions," as the goals, sets the reduction targets by different categories of each pollution for each sub-projects as the main objective of the future.
(4)About the 17 air quality purification areas, project group accomplished each work item, environmental Maintenance and air quality purification areas billboard updates, conducts the painting event and environmental education activities, and ycling Events for the peoples in Penghu get closes to nature life.
2. Achievements in PM2.5 source developing and improvement strategies.
(1)The project aims to execute for PM2.5 sampling and chemical composition analysis, in order to discern the physical and chemical characteristics and to explore the ontribution of pollution sources and analysis the feasible transmission paths by backward trajectory.
(2)Establish the distribution characteristics of PM2.5 in air quality unhealthy event in the past year, and analyze trends variation between seasonal and PM2.5 concentrations, PM2.5 sampling, chemical composition analysis, fingerprint data establishment, path sources and to develop analytical and PM2.5 contribution and measures.
