    Polycyclic aromatic hydrocarbons (PAHs) and linear alkylbenzenes (LABs) were used as anthropogenic markers of organic chemical pollution of sediments in the Selangor River, Peninsular Malaysia. This study was conducted on sediment samples from the beginning of the estuary to the upstream river during dry and rainy seasons.

    Examination of barnacles potential to be used as bioindicators of persistent organic pollutants in coastal ecosystem: A Malaysia case study
    (Elsevier, 2021) Vahab Vaezzadeh; Margaret William Thomes; Tatsuya Kunisue; Nguyen Minh Tue; Gan Zhang; Mohamad Pauzi Zakaria; Yang Amri Affendi; Fook Choy Yap; Li Lee Chew; Hong Wooi Teoh; Choon Weng Lee; Chui Wei Bong
    This is the first study attempting to assess the suitability of barnacles as bioindicators of persistent organic pollutants (POPs) in coastal environments. Barnacles were collected from the coasts around Peninsular Malaysia and analyzed for POPs including polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs).

    The aim of this a pioneering research is to investigate linear alkylbenzenes (LABs) as biomarkers of sewage pollution in sediments collected from four rivers and estuaries of the south and east of Peninsular Malaysia. The sediment samples went through soxhlet extraction, two-step column chromatography purification, fractionation and gas chromatography–mass spectrometry (GC–MS) analysis.

    Seasonal variability of anthropogenic indices of PAHs in sediment from the Kuala Selangor River, west coast Peninsular Malaysia
    (Springer, 2018) Najat Masood; Normala Halimoon; Ahmad Zaharin Aris; Mohamad Pauzi Zakaria; Vahab Vaezzadeh; Sami M. Magam; Shuhaimi Mustafa; Masni Mohd Ali; Mehrzad Keshavarzifard; Sadeq Abdullah Abdo Alkhadher; Chui Wei Bong; Murad Ali Alsalahi
    Rapid increase in industrialization and urbanization in the west coast of Peninsular Malaysia has led to the intense release of petroleum and products of petroleum into the environment. Surface sediment samples were collected from the Selangor River in the west coast of Peninsular Malaysia during four climatic seasons and analyzed for PAHs and biomarkers (hopanes).
