The results show that a proportion of the BB plume was blocked and compressed at the windward side of CMR. High-altitude BB plume is shown to influence air quality on the ground via three mechanisms: (1) the subsidence in the anticyclone, (2) the downward motion in the cold surge, and (3) the vertical mixing of the boundary layer over land. Two case studies are further investigated to probe the chemical evolution of the air parcel approaching Mt. Lulin. The first case shows that the third mechanism also explained the increase in the concentrations of peroxyacyl nitrate (PAN), higher peroxyacyl nitrate (PANX), NH 3 , SO 2 , and volatile organic compounds in the BB plume when entering the land over western Taiwan. Meanwhile, the percentage of NO 3 − in the plume is also significantly increased. The second case reveals that valley wind transported air pollutants from the ground to the mountains. The air parcel, accompanied with considerable concentrations of PAN, PANX, SULF, and anthropogenic secondary organic aerosol, moved up Mt. Lulin. The pollutant concentrations, except for elemental carbon, in the air parcel decreased on approach to Mt. Lulin because the air parcel was mixed with a clean air. 其他題名： Aerosol Air Qual.

We monitored Asian dust events in Taipei County, Taiwan from January 2003 to June 2004. We used duplicate Burkard portable air samplers to collect ambient fungi before, during, and after dust events. Six transported Asian dust events were monitored during the study period. Elevated concentrations of Aspergillus ( A. niger , specifically), Coelomycetes , Rhinocladiella , Sporothrix and Verticillium were noted ( p < 0.05) during Asian dust periods. Botryosporium and Trichothecium were only recovered during dust event days. Multiple regression analysis showed that fungal levels were positively associated with temperature, wind speed, rainfall, non-methane hydrocarbons and particulates with aerodynamic diameters ≤10 μm (PM 10 ), and negatively correlated with relative humidity and ozone. Our results demonstrated that Asian dust events affected ambient fungal concentrations and compositions in northern Taiwan. Ambient fungi also had complex dynamics with air pollutants and meteorological factors. Future studies should explore the health impacts of ambient fungi during Asian dust events, adjusting for the synergistic/antagonistic effects of weather and air pollutants. 其他題名： Int J Biometeorol 出版者： Berlin/Heidelberg: Springer Science and Business Media LLC 出版日期： 2012-03-01 出處： International Journal of Biometeorology, 2012-03, Vol.56 (2), p.211-219 資源來源： Agricultural & Environmental Science Collection 版權： ISB 2011 版權： ISB 2012 識別號： ISSN: 0020-7128 識別號： ISSN: 1432-1254 識別號： EISSN: 1432-1254 識別號： DOI: 10.1007/s00484-011-0413-x 識別號： PMID: 21328007 <br> Thu, 23 Apr 2026 07:08:49 GMT https://ir.lib.ncu.edu.tw/handle/987654321/108820 title: The association of ambient air pollution with airway inflammation in schoolchildren abstract: 出版者： Oxford University Press (OUP) 出版日期： 2012-03-09 出處： American Journal of Epidemiology, 2012-03, Vol.175 (8), p.764-774 識別號： ISSN: 0002-9262 識別號： DOI: 10.1093/aje/kwr380 <br> Thu, 23 Apr 2026 07:08:47 GMT https://ir.lib.ncu.edu.tw/handle/987654321/108817 title: Simulating the transport and chemical evolution of biomass burning pollutants originating from Southeast Asia during 7-SEAS/2010 Dongsha experiment abstract: 摘要： This study aimed to simulate the transport of biomass burning (BB) aerosol originating from Southeast Asia (SEA) during the Dongsha Experiment conducted from March 2010 to April 2010. Transport pathways were reanalyzed and steering flow in the mid-latitude areas and anticyclones in low-latitude areas were found to control the transport of BB plume after it was injected to a high atmosphere. For the 12 simulated and observed events at Mt. Lulin (2862 m MSL; 23°28′07″ N, 120°52′25″ E), the 72 h backward trajectories were all tracked back to southern China and northern Indochina, which were the locations of the largest BB fire activities in SEA. Chemical evolutions of BB pollutants along the moving trajectories showed that organic matter was always the dominant component in PM2.5, consistent with the observations at both near-source regions and Mt. Lulin. For nitrogen species, nearly all NOx molecules oxidized into HNO3, NO3−, PAN, and PANX in fires or near fires. The synchronic consumption of NOx, SO2, and NH3 explained the production of the major components of inorganic salts. In the moving BB plume, sulfate concentration increased with decreased nitrate concentration. Ratios of ammonium to PM2.5 and elemental carbon to PM2.5 remained nearly constant because additional sources were lacking. •Reanalysis of transport of biomass burning plume originating from SEA.•Chemical evolution of biomass burning pollutants during long-range transport.•Combine WRF/HYSPLIT/CMAQ to analyze the compositions of biomass burning plume. 出版者： Elsevier Ltd 出版日期： 2015-07 出處： Atmospheric environment (1994), 2015-07, Vol.112, p.294-305 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2015 Elsevier Ltd 識別號： ISSN: 1352-2310 識別號： EISSN: 1873-2844 識別號： DOI: 10.1016/j.atmosenv.2015.04.055 <br> Thu, 23 Apr 2026 07:08:38 GMT
