An investigation on the relationship between land use composition and PM10 pollution in Iskandar Malaysia
This paper discusses the relationship between land use composition and the degree of air pollution, specifically PM10, in Iskandar Malaysia. Aspires to be a low carbon region and a smart city, Iskandar Malaysia has to meet the social and economic needs of its growing population while taking care of...

This paper discusses the relationship between land use composition and the degree of air pollution, specifically PM10, in Iskandar Malaysia. Aspires to be a low carbon region and a smart city, Iskandar Malaysia has to meet the social and economic needs of its growing population while taking care of all the environmental challenges that come with rapid urbanization. The occurrence of regional haze episodes in the past has shrouded this region with particulate matters including PM10, but the major cause of the haze was extensive agricultural open burning rather than land use change. Since there is no doubt land use change itself can be a significant contributor to local PM10 concentration, separating PM10 caused by the local (land use change) source from that of the regional source would enable us to investigate the trend in local PM10 pollution level. Therefore, a study on the Iskandar Malaysia’s PM10 readings for the years 2002, 2006 and 2008 was carried out with the aim to identify the relationship between land use composition and PM10 concentration. The background concentration of the readings was extracted by using the base flow separation process commonly used in the hydrograph study. The extracted background concentration was then interpolated with the Terra MODIS level 2 product to identified the PM10 concentration for the whole Iskandar Malaysia region, spatially.
