The purpose of this project was to monitor the mass concentration of fine suspended particle (PM2.5) by manual collection in southern area of Taiwan. 10 monitoring stations of this project were included Putz, Chiayi, Sinying, Tainan, Cianjin, Meinong, Pingtung, Hengchun, Taitung and Magong. Each station estimates every year of the monitoring number was 121 times. 　　This project monitoring system was using a sampler of EPA provides (BGI PQ200), and to whom the method according to NIEA A205.11C. Since November 1, 2016 began monitoring operations every three days one time, up to October 31, 2018 for each station should monitor 243 times. 　　By the monitoring results, net of lack of time failure, the efficiency of each station samples ranged from 93.4%～99.2%, which Hengchun Station sample rate was the highest. For most monitoring stations, seasonal variations were obvious, PM2.5 concentration was highest in winter and lowest in summer.
