Penghu County is an outlying island county located on Taiwan Strait, and is composed of several Islands. There are 1 city and 5 townships in Penghu County, and 60% of the population lives in Magong City. The early economic activities were mainly fisheries. With the reduction of the fishery resources, it has been transformed into tourism county so far.
The Fireworks Festival and water sports in Penghu County every summer bring tourists, coming to travel by plane or ship. The number of tourists in 2018 reached a peak of 1,286 thousand people. In 2020 and 2021, affected by the COVID-19 epidemic, the number of tourists dropped to 1,143 thousand and 618 thousand respectively. According to the statistics of October 2022 of 1,070 thousand people, the epidemic slowed down and tourists rebounded.
Penghu County has an air quality monitor station in Magong of the Environmental Protection Agency to monitor the air quality of various pollutants. The proportion of AQI > 100 has dropped from 8.5% in 2018 to 3.0% in 2021, and 5.7% in November 2022. The largest index pollutant O3_8hr over the years is mainly distributed in March-May and September-November, PM2.5 is mainly distributed in January and February in 107-110 years, and there are no PM2.5 as the index pollutants in 2022 yet.
The average concentration of PM2.5 from 2016 to 2022 at Magong Station, both the automatic statistics and the manual statistics showed a downward trend year by year, and turn Penghu County to Class 2 control regions. As for O3_8hr, Penghu County does not meet air quality standards and still remains in Class 3 control regions from 2021. Compared with 2019~2020, it was affected by the interaction of longer days and higher concentration of overseas pollution migration in 2022, resulting in higher concentration of O3-8hr, which is the only pollutant that has not yet met the the air pollution control scheme target of 2022.
The Environmental Protection Agency announced in 2022 that it revised the emission inventory TEDS11.1. Compared with the previous version of TEDS10.1, the changes in emissions from various pollution sources were compared, including PM10, PM2.5, SOx, NOx and NMHC.
Penghu County air pollution control scheme has 9 control strategies, all of which have reached their quantitative targets by the end of November; among them, there are 3 strategies with reduction benefits, and all pollutants reduction achievement rates have all reached 100%.
In April and October of this year, two "Air Pollution Control Scheme Tracking and Review Meetings" were held, and three scholars were invited to attend the meeting for consultation and suggestions. 3 new control strategies were drawn up and the 3 existing strategies were adjusted. In addition, the "Air Pollution Reduction Inter-Bureau Coordination and Indoor Air Quality Management and Health Impact Explanation Meeting" was held to urge all bureaus to assist in control measures, and to promote the importance of indoor air quality.
This project establishes the inspection procedures for each project and checks the statistics submitted by each project, and hold relative review meetings to improve the overall execution effectiveness. In addition, this project invited scholars to evaluate the on-site implementation effectiveness of each project, and tracked the results in the following month.
As of November 2022, emergency response measures for poor air quality have been adopted 6 times, all of which have notified each project and reported to the agency website on time. In order to strengthen the county's ability to respond when the air quality deteriorates, the "Air Quality Deterioration Emergency Response Education Training and Air Quality Management and Health Impact Explanation Session" was held in June to explain the revision of regulations and the main points of response operations. At the end of September, "Emergency Practice for Severe Deterioration of Air Quality Meeting" was held.
This project cooperated with the relevant bureaus of the county government to promote environmental greening and beautification, reduce the emission of dust from wind erosion on bare land, and increased the green area from 8.85m2/person in 2010 to 12.52 m2/person in November 2022. This year, 7 air quality purification areas were promoted to be adopted by private enterprises and volunteers, and experts were invited to self-evaluate the air purification areas. A promotion meeting on the installation of green walls was held, and setting up planning were carried out for campuses that were willing to set up green walls. Subsequently, 5 schools submitted applications, and the number of installations was 5 times that of last year.
