TAILIEUCHUNG - AIR POLLUTION DETERMINATION USING REMOTE SENSING TECHNIQUE

Historically, the Ontario Medical Association (OMA) has taken a strong stand advocating reductions in air pollution in Ontario as an essential means to improve public health. Beginning in 1967, the Ontario Medical Association Council endorsed a program of air pollution control in Ontario which included the establishment of monitoring stations and regulation of emissions from industry and vehicular traffic (15). Shortly thereafter, the government enacted the Air Pollution Control Act encompassing a number of the recommendations from the OMA. This initiative established the principle of preventative health care through improvements in environmental quality. The OMA has continued in these early footsteps and in. | 5 Air Pollution Determination Using Remote Sensing Technique H. s. Lim M. z. Matjafri K. Abdullah and c. J. Wong School ofPhysics Uniuersiti Sains Malaysia 11800 USM Penang Malaysia. 1. Introduction Environmental pollution become more and more serious due to today s development all around the world. Environmental pollution is our concern nowadays because all the daily activities are related to the environment. In order to ensure this situation is under control Malaysia s government has already established a network throughout Malaysia to monitor this situation. Air pollution is one of the most important environmental problems which concentrates mostly in cities. Air pollution in Asian cities has grown with the progressing industrialization and urbanization. Air quality standards often refer to respirable suspended particulate matter PM being aerosols with a diameter smaller than 10 gm PM10 UNEP . Fine particles are of the greatest concern since they are capable of being easily transported over long distances on currents of air. Also fine particles may be drawn into the respiratory airways where they may adversely affect health. Recently the attention of scientists has been drawn towards studying the fraction and even smaller particles which can penetrate the very deepest parts of the lung Environmental Protection Service Tameside MBC Council Offices 2008 . The effects of environmental pollution in the study area are shown in Figure 1. The objective of air quality monitoring is to obtain an estimate of pollutant total suspended particulates TSP concentrations Ung et al. 2001a 2001b . First compared to atmospheric gases aerosol is highly inhomogeneous and variable that is aerosol observations have to be global and continuous. Second the available accuracy of aerosol characterization is often not sufficient. For instance in situ measurements traditionally considered as the most reliable observations are inappropriate for global monitoring of aerosol radiative .
