Yusoff; Abu Bakar Salleh; Sarva Mangala PraveenaThe aim of the present study was to appraise the levels of heavy metal contamination (Zn and Pb) in sediment of the Langat River (Selangor, Malaysia). Samples were collected randomly from 15 sampling stations located along the Langat River.

Kadhum; Mohd Yusoff Ishak; Syaizwan Zahmir ZulkifliThe Bernam River is one of the most important rivers in Malaysia in that it provides water for industries and agriculture located along its banks. The present study was conducted to assess the level of contamination of heavy metals (Cd, Ni, Cr, Sn, and Fe) in surface sediments in the Bernam River. Nine surface sediment samples were collected from the lower, middle, and upper courses of the river.Item Embargo Estimation and influence of physicochemical properties and chemical fractions of surface sediment on the bioaccessibility of Cd and Hg contaminant in Langat River, Malaysia(Springer, 2017) Safaa A. Kadhum; Mohd Yusoff Ishak; Syaizwan Zahmir ZulkifliThis study applied the use of sequential extraction technique and simple bioaccessibility extraction test to quantify the bioavailable fractions and the human bioaccessible concentration of metals collected from nine stations in surface sediment of the Langat River.Item Embargo Metal concentrations in sediments from tourist beaches of Miri City, Sarawak, Malaysia (Borneo Island)(Elsevier, 2013) R. Nagarajan; M.P. Jonathan; Priyadarsi D. Roy; L. Wai-Hwa; M.V. Prasanna; S.K. Sarkar; M. Navarrete-LópezForty-three sediment samples were collected from the beaches of Miri City, Sarawak, Malaysia to identify the enrichment of partially leached trace metals (PLTMs) from six different tourist beaches. The samples were analyzed for PLTMs Fe, Mn, Cr, Co, Cu, Ni, Pb, Sr and Zn.Item Embargo Geofractionation of heavy metals and application of indices for pollution prediction in paddy field soil of Tumpat, Malaysia(Springer, 2013) Ai Yin Sow; Ahmad Ismail; Syaizwan Zahmir ZulkifliThe present study investigates the concentration of Pb, Cd, Ni, Zn, and Cu in the paddy field soils collected from Tumpat, Kelantan. Soil samples were treated with sequential extraction to distinguish the anthropogenic and lithogenic origin of Pb, Cd, Ni, Zn, and Cu. ELFE and oxidizable-organic fractions were detected as the lowest accumulation of Pb, Cd, Ni, Zn, and Cu. Therefore, all the heavy metals examined were concentrated, particularly in resistant fraction, indicating that those heavy metals occurred and accumulated in an unavailable form.Item Embargo Baseline distributions and sources of Polycyclic Aromatic Hydrocarbons (PAHs) in the surface sediments from the Prai and Malacca Rivers, Peninsular Malaysia(Elsevier, 2014) Mehrzad Keshavarzifard; Mohamad Pauzi Zakaria; Tan Shau Hwai; Ferdius@Ferdius Mohamat Yusuff; Shuhaimi Mustafa; Vahab Vaezzadeh; Sami M. Magam; Najat Masood; Sadeq A.A. Alkhadher; Fatemeh Abootalebi-JahromiIn this study, the surface sediments of the Malacca and Prai Rivers were analyzed to identify the distributions, and sources of Polycyclic Aromatic Hydrocarbons (PAHs).Item Embargo Evaluation of radionuclides transfer from soil-to-edible flora and estimation of radiological dose to the Malaysian populace(Elsevier, 2016) Mayeen Uddin Khandaker; Noor Liyana Mohd Nasir; Kh Asaduzzaman; Michael Adekunle Olatunji; Yusoff Mohd Amin; Hasan Abu Kassim; D.A. Bradley; P.J. Jojo; Tareq AlrefaeMalaysia, a rapidly growing industrial country, is susceptible to pollution via large-scale industrial engagements and associated human activities. One particular concern is the potential impact upon the quality of locally resourced vegetables, foodstuffs that contain important nutrients necessary for good health, forming an essential part of the Malaysian diet. As a part of this, it is of importance for there to be accurate knowledge of radioactive material uptake in these vegetables, not least in respect of any public health detriment.Item Embargo Distribution and source apportionment of polycyclic aromatic hydrocarbons (PAHs) in surface soils from five different locations in Klang Valley, Malaysia(Springer, 2012) Ee Von Lau; Suyin Gan; Hoon Kiat NgThe concentrations of polycyclic aromatic hydrocarbons (PAHs) in soil samples were measured at five different sites within Klang Valley, Malaysia.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 Heavy metals from agricultural soils from Cameron Highlands, Pahang, and Cheras, Kuala Lumpur, Malaysia(Springer, 2006) J.
