The Influence of Meteorological Parameters on Respirable and Inhalabe Particle During wet Season

Air Pollution is a problem because human activities threaten to overload the atmosphere with wastes beyond the ability of wind and weather to disperse and dilute these pollutants. An effective air resources management program must take into account, the effects of meteorological parameters on transport and dilution and the natural cleansing processes of the atmosphere. Particulate pollutants tend to coagulate, increase in size and fall to earth. Thus coarse or inhalable particulates generally cause air pollution problems of a localized nature. However, lighter particulate and gaseous pollutant are influenced by action of atmospheric diffusion and may be carried to great distances from their sources of origin. Any study of air pollution should include a study of the weather patterns (meteorology) of the local area because the fate of air pollutants is influenced by the movements and characteristics of the air mass into which they are emitted. The main concentration of respirable suspended particulate matter was 104.17 – 260.42 and the inhalable suspended particulate matter was in a range of 104.17 - 434.03. The correlation of inhalable and respirable suspended particulate matter was good and positive (r = 0.73.); And the correlation of respirable and inhalable fraction with wind speed and temperature were positive while with relative, humidity were negative. The spatial distribution of inhalable and respirable were significant and remarkable (P<0.05).
