Air pollution is define as the presence of chemicals in the atmosphere high enough to affect climate and harm organisms and materials. Gaseous or particulate substances released into the atmosphere in sufficient quantities or concentrations to cause injury to plants,animals, or humans.
Other sources of pollutants included dust and fine particulate, which were contributed by the inefficiency of diesel-powered vehicles and also the smoke aerosol from fires on Peninsular Malaysia. Meteorological aspects like wind profile, temperature, atmospheric pressure, and others also contribute to air pollution, such as the transformation of emissions into photochemical smog, mixing of the pollutants, acid rain and many more. Although the higher phytotoxic risk was found especially in the southern.
Generally, studies have concentrated on those air pollutants typical of the urban and industrial environment namely, nitrogen oxides (NO2 and NO), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3) and particulate matter (vesilind at al 1988)
According to malaysian air quality indices (MAQI) proposed by Azman et al (1994), there are five parameters were chosen for determine air pollution index which are suspended particulate matter with the diameter small than 10 micrometer (PM10), sulfur dioxide (SO2), nitrogen dioxides (NO2), carbon monoxide (CO) and ozone (O3).
These studies were carried out to determine and evaluate the concentration of the five air pollutants in several industrial area namely Sepanggar (sabah), Teluk kalung (Terengganu), Nilai (Negeri Sembilan), dan Air Keruh (Melaka). The calculation of air pollution index from the data collected will determined the situation of air pollution in the study areas.
