Item Restricted A preliminary study on humic-like substances in particulate matter in Malaysia influenced by Indonesian peatland fires(Elsevier, 2021) Yusuke Fujii; Susumu Tohno; Kazuhiro Ikeda; Mastura Mahmud; Norimichi TakenakaIn this paper, ambient total suspended particulates (TSP) with a focus on humic-like substances (HULIS) are characterized based on intensive ground-based field samplings collected in Malaysia during non-haze and haze periods caused by peatland fires on the Indonesian island of Sumatra. Furthermore, concentrations of water-soluble organic carbon (WSOC) and carbon content of HULIS (HULIS-C) were determined, and fluorescence spectra of the HULIS samples were recorded by excitation emission matrix (EEM) fluorescence spectroscopy.Item Metadata only Greenhouse Gas Emissions From A Land Use Change Activity During A Haze Episode in Southeast Asia(Penerbit UKM) Mastura MahmudItem Open Access Influence of urban air pollution on the population in the Klang Valley, Malaysia: a spatial approach(Springer, 2022) Siti Haslina Mohd Shafie; Mastura Mahmud; Suzani Mohamad; Nor Lita Fadilah Rameli; Ramdzani Abdullah; Ahmad Fariz MohamedUrban air pollution resulting from economic growth as well as urbanization impacts the health of inhabitants. This study aims to examine the spatial distribution of particulate matter (PM10) and the risk of exposure for the population in the Klang Valley, an urban conglomeration centred in Kuala Lumpur, Malaysia.The inverse distance weighted (IDW) interpolation technique in the ArcGIS platform was used to map the air quality from fve air monitoring stations. Spatial statistics of the Global Moran’s I Spatial Autocorrelation and Optimized Hot Spot Analysis were used to estimate the spatial clustering of PM10. The population-weighted exposurelevel (PWEL) technique was used to calculate the population density susceptible to PM10 and the AirQ+model was applied to estimate the proportion of the adult population at risk of chronic bronchitis due to long-term exposure to PM10 concentrations in the Klang Valley.Item Metadata only Kajian Pencemaran Udara Berikutan Peristiwa Jerebu Pada Tahun 2005: Kajian Kes diPerai,Pulau Pinang(Penerbit UKM) Mastura Mahmud; Nuur Huraizah Abu HanifiahItem Metadata only The La Nina Episode And The Heavy Winter Rainfall Of 1999 Over Peninsular Malaysia(Penerbit UKM) Mastura MahmudItem Metadata only
