AbstractAir pollution in Malaysia is largely attributed to motor vehicles and land transportation, industrial activities and open burning. It has a hazardous effect on the public’s health and the environment. This study focuses on the spatial analysis of carbon monoxide (CO) and ozone (O3) concentrations trend in Klang Valley stations, specifically in Klang, Petaling Jaya, Kajang, Shah Alam and Cheras from 2000 to 2009. The study used the Inverse Distance Weighted (IDW) interpolation technique under the Geographic Information System (GIS). This study found that the distribution pattern of CO spatial concentrations in the Klang Valley is the highest concentration and reached 2.5 ppm, especially in Klang and Petaling Jaya stations in 2002 and 2003. However, the annual concentration of O3 recorded in Klang, Petaling Jaya, Kajang, Shah Alam, and Cheras stations from 2004 to 2009 is between 0.01 to 0.025 ppm. While air quality legislations have been introduced in Malaysia, policies and regulations being established by the government, their enforcement is still weak. Subsequently, air pollution is still a significant issue in Malaysia. Strong cooperation between the government, stakeholders and the local community is important to promote environmental sustainability and improve the community’s well-being. Keywords: Air pollution; Geographic Information System (GIS); Air Quality Policy; Malaysia

Air Pollution Control

The development of industry and the increase of transportation mode are directly proportional to the decrease in air quality. Some important pollutants have a negative impact on human health and the environment such as nitrogen dioxide (NO2) and ozone (O3). Distribution of NO2 and O3 concentrations from various sources of emissions in urban areas will provide basic information in the determination of policies, programs and regulations related to air pollution control. This study aims to map and analyze the concentration distribution of NO2 and O3 pollutants in Medan City. This research was conducted by a manual sampling of NO2 and O3 at 12 (twelve) points in Medan City. The sampling of NO2 and O3 concentrations is using impinger and then analyzed in a laboratory. The results showed that NO2 pollutant concentration in Medan City ranged from 21.33-306.19 |ig/m3. Meanwhile, for O3 concentrations ranged from 19.7-205.8 |ig/m3. Mapping of NO2 and O3 concentration using Geographic Information System obtained area that has the highest concentration of both NO2 and O3 is in Sub District of Medan Belawan. Furthermore, efforts to control air pollution can be done by applying clean technology to industry and encouraging the use of mass transportation.
