Item Open Access 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 Open Access Evaluation and assessment of baseline metal contamination in surface sediments from the Bernam River, Malaysia(Springer, 2016) Safaa A. 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 Restricted Evaluation of the status and distributions of heavy metal pollution in surface sediments of the Langat River Basin in Selangor Malaysia(Elsevier, 2015) Safaa A. Kadhum; Mohd Yusoff Ishak; Syaizwan Zahmir Zulkifli; Rohasliney binti HashimThe concentration of four metals: Cd, Ni, Cr, and Sn, in the surface sediment samples from the Langat River were evaluated. Multivariate techniques were used to apportion the sources of the metals.Item Restricted Impacts of and adaptation to climate change on the oil palm in Malaysia: a systematic review(Springer, 2021) Ahmed Abubakar; Mohd Yusoff Ishak; Abdullah Ahmad MakmomThe study aims to examine the impact of climate change on oil palm production and identify the farmers’ adaptation strategies to the impacts of climate change in Malaysia. This study was conducted a comprehensive review of the articles published from 2000 to 2021 in the contexts of climate change and oil palm production in Malaysia.
