| Popis: | 105 This study measured ambient air particulates, metallic elements and Hg(p) in ambient air by using PS-1, VAP, MOUDI and Wilbur PM2.5 samplers at Gome-Ming Junior High School, Kal-Mei wetlands and H.P.B Optoelectronics sampling sites during Jul. 2016 to Mar. 2017. In addition, the method of HYSPLIT was used to find the pollutants parcels sources. Statistical ANOVA and COD methods were also used to test the mean concentrations differences among seasonal variations for ambient air particulates and metallic elements. Moreover, PCA method was used to identify the pollutants sources at GMS, KMW and H.P.B. sampling sites. The results indicated that KMW has the highest average TSP pollutants concentrations, and H.P.B. has the highest average PM2.5 pollutants concentrations. The main transport pathway was came from Taiwan and China seashores areas. In addition, ANOVA analysis displayed different seasons had no significant differences for particulates and metallic elements pollutants concentrations. Beside, we concluded that three sampling sites have similar pollutants sources by way of Coefficient of Divergence analysis. Finally, Principal Component Analysis have the following results 1) The pollutants sources were came from Taichung airport station and aerospace industrial development corporation at GMS. 2) The pollutants sources were came from Kwan-Lien Park (THKLP) at KMW. 3) The pollutants sources were came from Taichung Science Park at H.P.B. sampling site. |
