Item Embargo An assessment of selected trace elements in intertidal surface sediments collected from the Peninsular Malaysia(Springer, 2010) Syaizwan Zahmir Zulkifli; Ferdaus Mohamat-Yusuff; Takaomi Arai; Ahmad Ismail; Nobuyuki MiyazakiConcentrations of 11 trace elements (V, Cr, Co, Ni, Cu, Zn, As, Ag, Cd, Pb, and U) were determined in the intertidal surface sediments of Peninsular Malaysia.Item Embargo Greenhouse gas emissions during plantation stage of palm oil-based biofuel production addressing different land conversion scenarios in Malaysia(Springer, 2017) Faradiella Mohd Kusin; Nurul Izzati Mat Akhir; Ferdaus Mohamat-Yusuff; Muhamad AwangThe environmental impacts with regard to agro-based biofuel production have been associated with the impact of greenhouse gas (GHG) emissions. In this study, field GHG emissions during plantation stage of palm oil-based biofuel production associated with land use changes for oil palm plantation development have been evaluated.Item Restricted Imposex in Thais gradata as a Biomarker for TBT Contamination on the Southern Coast of Peninsular Malaysia(Springer, 2010) Ferdaus Mohamat-Yusuff; Syaizwan Zahmir Zulkifli; Ahmad Ismail; Hiroya Harino; Mohd Kamil Yusoff; Takaomi AraiThais gradata samples were collected from six locations along the southern shores of Peninsular Malaysia and analyzed for imposex incidence and organotin (butyltins (BTs), including tributyltin, dibutyltin, and monobutyltin, and phenyltins (PTs), including triphenyltin, diphenyltin, and monophenyltin concentrations), in tissue burden.Item Embargo Johor Strait as a hotspot for trace elements contamination in Peninsular Malaysia(Springer, 2010) Syaizwan Zahmir Zulkifli; Ahmad Ismail; Ferdaus Mohamat-Yusuff; Takaomi Arai; Nobuyuki MiyazakiPresent study was conducted to evaluate current status of trace elements contamination in the surface sediments of the Johor Strait.Item Embargo Nitrous oxide emission from nitrogen fertiliser application in oil palm plantation of different stages(Inderscience Enterprises Ltd, 2016) Faradiella Mohd Kusin; Nurul Izzati Mat Akhir; Ferdaus Mohamat-Yusuff; Muhamad AwangThe release of nitrous oxide (N2O) from agricultural activities contributes to the increase of greenhouse gases in the atmosphere. In this study, the amount of nitrogen fertiliser used in an oil palm plantation of different stages (immature and mature) was estimated. Data of fertilising scheme at the oil palm plantation for oil palms varying in age (planted between 1986 and 2009) was used. Estimation of nitrous oxide emissions and the resulting CO2-equivalent (CO2-eq) emissions were calculated for each category of the oil palm.
