According to the data of EPA Tainan Automatic Test-Site (Sin-ing & Sanhwa Test-site), it shows that the reason for PSI>100 is due to the aerosol and the ozone, the aerosol is mainly from the cars and the building development. The Bureau of Environmental Protection Tainan County matches up with the “Project of enhancing street dust sweeping & washing” of EPA, and goes keeping the execution from last year. At first the test-sites of the county, the boundaries and population dense place, high flow of transportation and heavy dust area should be done to improve the air quality.The project is executed by scheduled progress and achieved the assessed score of EPA for street dust sweeping & washing. It results in reducing the thickness of aerosol and the rate of harmful PSI at two tested-sites. We are looking forward to promoting the cognition and support for the project from people, meeting the middle & long term aim of the Bureau of Environmental Protection Tainan County, and lifting up the environmental quality of residents’ life.
