Title：Uptake rate evaluation of common tree species against volatile organic and other air pollutants
This project is to evaluate the uptake rate or air-cleaning efficiency of common tree species against nitrogen dioxide, sulfur dioxide, ozone and peroxyacetyl nitrate in Taiwan and to measure the isoprene emission rates of them. A branch enclosure method using corresponding monitors was used to measure the pollutant uptake rates of more than 20 common tree species in this study. Results showed that in the winter season most of the trees still uptake the pollutants including nitrogen dioxide and sulfur dioxide, although the uptake rates were lower. The uptake rates showed significant diurnal fluctuation and this phenomenon needs more studied in the future. . Generally the air cleaning efficiency varied among different tree species, with 10 folds difference between the top and the least. The PAN uptake rates were generally 10 t0 100 times lower than those of ozone, nitrogen dioxide or sulfur dioxide. In the winter with low temperature the isoprene emission rates were near zero as compared to those in the summer. This study also screened 21 shrub, 11 herbaceous plant species for their isoprene emission rates, showing only two shrubs emitted the isoprene. A comprehensive evaluation was given to all tested common tree species and a ranking scale from A to D was adopted for ranking them on the basis of pollution uptake rates. These results suggest that the species with high uptake rates should be grown in urban areas to clean the dirty air and uptake the air pollutants and carbon dioxide. ， 欄位Project Year的內容是2004 ， 欄位Organizer的內容是Department of Air Quality Protection ＆amp; Noise Control ， 欄位Executive Unit的內容是國立台灣大學植物病理與微生物學系 ， 欄位Reporting download URL的內容是https://epq.epa.gov.tw/ProjectDoc/FileDownload?fid=3516&proj_id=A000000357915&doc_kind=1 ， 欄位Publish Date的內容是20060101 。
