1. Intriduction
The annual average concentration of PM2.5 at Touliu in 2013 was 34.0μg/m3, which is highest one among 30 sites managed by EPA in Taiwan. To realize the people living in Yunlin area's health risk exposured long term on such high air pollution, and explore the improvement strategy of air pollution for reducing health risk, we have to do something in the future including air quality monotoring, composition analysis of PM2.5, emission reduction measures for various sources, health risk analysis, and etc. This study is subjected to proposed a study plan for the work to collect more information about air quality and its composition, a better understanding of the causes of air pollution, and control strategies to further impove air quality and reduce health risk caused by air pollution in Yunlin area.
2. Object
(1) Collection and analysis of information about air quality data and past studies regarding Yunlin's air pollution.
(2) To realize the chacteristics of Yunlin's air pollution issue, and propose a study plan for the work to collect more information about air quality and its composition, a better understanding of the causes of air pollution, and control strategies to further impove air quality in Yunlin area.
(3) To realize the chacteristics of Yunlin's health risk issue, and propose a study plan for a better understanding of current health risk, and control strategies to reduce health risk caused by air pollution in Yunlin area.
3. Results
(1) Among the three monitoring sites built by Taiwan EPA, the highest PM2.5 concentration ocurred at Touliu, the next on is Lunbei, and lowest on is Taisi.
(2) The exact reason why PM2.5 higher at Touliu is not clear so far, but the terrain effect and fugitive dust of river surrounding Touliu could be somehow possible reason have been pointed out.
(3) A procedure of air quality management have been prososed in the study including air quality monitoring and observation, source inventory and emission estimation, air quality modeling, control strategy for emision reduction, and policy decision and implementation.
(4) A future study plan have been proposed for the work to collect more information about air quality and its composition, a better understanding of the causes of air pollution, and control strategies to further impove air quality in Yunlin area including long-term monitoring and obsevation of PM2.5 and its compostion, receptor model analysis, emission estimation for VOCs released by off-shore industry park, fugitive dust estimation model, integrated processes analysis for formation mechanisms of PM2.5, effectiveness assessment of control strategy, establishment of warning system for deteriorate event, and establishment of comunication platform for information exchange about PM2.5 and others.
(5) A future study plan have been also proposed for a better understanding of current health risk, and strategies to reduce health risk caused by air pollution in Yunlin area including long term, totally, and deeply health risk and effect analysis for PM2.5 exposure, establishment of data bank for health effect by PM2.5 in Yunlin, exploreing the relation between PM2.5 concentration and mortality rate, and etc.
