Effects of sub-urban area development in Selangor to air pollution index from 2012-2014: article

This study aims to explore the trend of ambient air pollution (i.e. PM10, CO, NO2, O3) within the two selected Malaysian air monitoring stations in Selangor of three years database from 2012 to 2014. The air pollution databases were compared to the recommended Malaysian Ambient Air Quality Guidelines (MAAQG) and the association between air pollutants and meteorological factors also assessed. In addition, data analysis has been carried out in the following developed sub-urban areas: Banting and Kuala Selangor. Hourly API from each air monitoring station was analysed where API was based on the average concentration of PM10, PM2.5, O3, CO, SO2, and NO2. Based on the result, it can be said that the year 2014 was indeed the worst year for Banting and Kuala Selangor especially during the month of March, the highest reading recorded in Malaysia was in Banting and Kuala Selangor reaching hazardous level exceeding 300. The government has spent RM2.244 billion for environmental protection which increased by 0.3 percent compared to the previous years. Air quality trends for the criteria pollutants in these research generally continuing to show downward trends or stable trends well below the level of MAAQG except for particulate matter. However, PM10 and O3 are the crucial pollutants in Selangor.
