Abstract

This study was to collect ambient air TSP, dry depositions, PM10, PM2.5 compositions and analyze the ionic species (F-, Cl-, NO3-, SO42-) compositions which attached in TSP, dry depositions, PM10, PM2.5 for these semi-open/outdoor environments at a concrete processing factory in ChangHua Coastal Park. And the comparisons of ambient air ionic species (F-, Cl-, NO3-, SO42-) in TSP, dry depositions, PM10, PM2.5 compositions for these semi-open/outdoor environments were also discussed during the year of 2017-half year observations. And the results indicated that the average ionic species SO42- was ranked highest average compositions in dry depositions, PM10, PM2.5 when compared with those of the other ionic species (F-, Cl-, NO3-) while the ionic species for Cl- was ranked highest average compositions in TSP when compared with those of the other ionic species (F-, NO3-, SO42-) at this semi-open/outdoor environments sampling site at a concrete processing factory in Changhua Coastal Park. In addition, the average ionic SO42- compositions in semi-open environment were higher than that of outdoor environment. In addition, ionic species SO42- occupied were than 60% of the compositions percentages when compared with all the ionic species at both PM10 and PM2.5. And ionic species SO42- compositions in TSP was occupied more than 50% of than concentrations percentages when compared with all the ionic species. Finally, ionic species SO42- compositions in dry depositions was occupied more than 40% of compositions percentages when compared with all the other ionic species in this study.
