Air pollution control is an important part of environmental protection for all mankind, the control methods require multiple fronts, therefore, the Environmental Protection Administration (EPA) has used a portion of air pollution control fund to establish the air quality purification area（hereinafter called the Aquapu Area）for tree planting, as the result, to improve the air quality of Taiwan. Since then, EPA has approved a total of 939 Aquapu areas covering an area of about 1,772.96 hectares and the shaded bike trail length of about 293 kilometers. The content of this project is a continuous work to provide the inventory, assessment and monitoring related works of the existing and newly built Aquapu Area in order to assist EPA to establish a quality living environment in Taiwan. This project has also completed (1) the revision of existing guidelines and criteria used as the bases for Aquapu Areas adoption. (2) on-site inventory, monitoring and assessment works. (3) updating related information regularly, updating and maintaining Aquapu Area website and plant nursery website in order to provide the latest status in implementation as well as to improve the performance and management efficiency. (4) updating and replenishing information of existing Green Network of Bicycle Trails website to provide cyclists with a convenient and fast inquiry system. A four-floor vertical green wall was established at Kaohsiung Municipal Nanzih Primary School and its effect on indoor air quality was determined. Results show that the temperatures, and concentration of formaldehyde, carbon dioxide and ozone were consistently lower in the classroom with the green wall than that with bare wall. Relative humidity ranged between 70%-75% in the classroom with green wall. PM2.5 and PM10 concentrations did not differ between the classrooms with or without green wall, probably due to the frequent variation of wind speed and direction. The optimum wind speed for a module of active living wall (ALW) was estimated at 0.6 m•s-1. Results reveal that ALW had consistently higher capacity for reduction in formaldehyde and PM10 on ten common indoor plants. The ALW module designed in this project had higher efficiency in reducing formaldehyde and CO2 than commercial air purifiers. The ALW could also decrease the formaldehyde concentrations in two clinics tested. Our working group have also provided EPA with all required administrative assistance, such as designing and manufacturing promotional materials; holding ten promotional and interpretive activities; seven「seeding teacher」training sessions and other related administrative assistances.
