Item Embargo A multidimensional approach for microplastics monitoring in two major tropical river basins, Malaysia(Elsevier, 2023) Sabiqah Tuan Anuar; Nor Salmi Abdullah; Nasehir Khan E.M Yahya; Teen Teen Chin; Ku Mohd Kalkausar Ku Yusoff; Yuzwan Mohamad; Alyza Azzura Azmi; Maisarah Jaafar; Noorlin Mohamad; Wan Mohd Afiq Wan Mohd Khalik; Yusof Shuaib IbrahimMicroplastics (MPs) with the size of 1 µm–5 mm are pollutants of great concern ubiquitously found in the environment. Existing efforts have found that most of the MPs present in the seas mainly originated from land via riverine inputs. Asian rivers are known to be among the top in microplastic emissions. However, field data are scarce, especially in Malaysia. This study presents the distribution and characteristics of MPs in the surface water of two major river basins of Malaysia, namely Langat River (West Coast/Straits of Malacca) and Kelantan River (East Coast/South China Sea). Water samples were collected at 21–22 locations in Kelantan and Langat rivers, covering the river, estuary and sea.Item Embargo BTEX compositions and its potential health impacts in Malaysia(Elsevier, 2019) Mohd Talib Latif; Fatimah Ahamad; Md Firoz Khan; Mohd Shahrul Mohd Nadzir; Murnira Othman; Mazrura Sahani; Muhammad Ikram Abdul Wahab; Noorlin Mohamad; Royston Uning; Seng Chee Poh; Muhammad Fais Fadzil; Justin Sentian; Norhayati Md Tahir; Haris Hafizal Abd HamidThis study aims to determine the composition of BTEX (benzene, toluene, ethylbenzene and xylene) and assess the risk to health at different sites in Malaysia. Continuous monitoring of BTEX in Kuala Lumpur City Centre, Kuala Terengganu, Kota Kinabalu and Fraser Hill were conducted using Online Gas Chromatograph.Item Embargo Composition of heavy metals in indoor dust and their possible exposure: A case study of preschool children in Malaysia(Springer, 2013) Mohd Talib Latif; Saw Mei Yong; Azlina Saad; Noorlin Mohamad; Nor Hafizah Baharudin; Mazlin Bin Mokhtar; Norhayati Mohd TahirThe aim of this study is to determine the levels of selected heavy metals (Pb, Zn, Cd, Fe and Cr) at ten preschools in Selangor, Malaysia. Dust samples from the interior of classrooms and surface soils were collected using soft paint brushes while Kimwipes were used to collect samples of dust from interior walls and children's palms. Heavy metals in the dust samples were determined using inductively coupled plasma mass spectrometry (ICP-MS).Item Embargo Composition of selected heavy metals in road dust from Kuala Lumpur city centre(Springer, 2014) Nur Mun’im Mohd Han; Mohd Talib Latif; Murnira Othman; Doreena Dominick; Noorlin Mohamad; Hafizan Juahir; Norhayati Mohd TahirThis study was carried out in order to determine the concentration of heavy metals, e.g., lead (Pb), cadmium (Cd), copper (Cu), zinc (Zn), iron (Fe), manganese (Mn), nickel (Ni) and chromium (Cr) in road dust in Kuala Lumpur's city centre. Samples were collected from four sampling locations, each of which had four sampling points and three replications.Item Embargo Concentration and source apportionment of volatile organic compounds (VOCs) in the ambient air of Kuala Lumpur, Malaysia(Springer, 2017) Puteri Nurafidah Hosaini; Md Firoz Khan; Nur Ili Hamizah Mustaffa; Norhaniza Amil; Noorlin Mohamad; Shoffian Amin Jaafar; Mohd Shahrul Mohd Nadzir; Mohd Talib LatifThe accumulation of volatile organic compounds (VOCs) in ambient air affects air quality through the generation of surface level ozone and secondary organic aerosol. A study of the distribution and source apportionment of VOCs was conducted at two stations to investigate the air quality status of Kuala Lumpur. Samples of ambient air were collected into Tedlar sampling bags using an air sampling pump and then pre-concentrated with solid-phase micro-extraction fibre. Gas chromatography-mass spectrometry (GC-MS) was employed to measure the VOC species.
