Vertical Distribution of Airborne Particulate Matter in a Tropical Urban Environment: Changes in Physical and Chemical Characteristics

摘要: Air pollution has become a subject of great interest on the global scale from both regulatory and scientific points view. This is result expanding economies, increasing population urbanization. Particulate matter serious concern in urban areas due to its adverse impacts human health (US EPA 2009). Most previous studies reported literature particulate air deal with temporal spatial distributions as part routine quality monitoring (Hitchins et al. 2000; Wu 2002; Levy 2003; Morawska 1999; Zhu 2002), but little work been done vertical distribution vicinity buildings. The horizontal particles because it helps town planners decide location buildings amenities considering degree exposure occupants fine ultra particles. In addition those studies, also merits consideration provides an understanding how are distributed respect height building so that one can natural intake building, or orientation based source pollution.
