    Microplastics (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.

    Microplastics analysis in Malaysian marine waters: A field study of Kuala Nerus and Kuantan
    (Elsevier, 2018) Wan Mohd Afiq Wan Mohd Khalik; Yusof Shuaib Ibrahim; Sabiqah Tuan Anuar; Sharumathiy Govindasamy; Nor Fadilah Baharuddin
    The first report on the emergence of microplastic in Malaysian marine waters was documented in this study. Water samples were collected from two regions, namely Kuala Nerus and Kuantan port, as the representatives of different anthropogenic activities. Identification of microplastic was performed based on physical characteristics (colour, shape, density) and chemical characterisation (ATR-FTIR analysis) for a functional group of polymers.

    Microplastics in seawater and zooplankton: A case study from Terengganu estuary and offshore waters, Malaysia
    (Elsevier, 2021) Zakaria Daoud Taha; Roswati Md Amin; Sabiqah Tuan Anuar; Ammar Arif Abdul Nasser; Erqa Shazira Sohaimi
    Widespread accumulation and distribution of microplastics at the sea surface raise concerns as the habitat is a feeding ground for zooplankton. As primary consumers, these organisms are closely connected to microplastic input in the marine food chain. Little comparative information currently exists about this problem in estuary and offshore systems. This study investigates microplastic distribution in the surface water and the potential ingestion of microplastics in selected taxonomic groups of zooplankton from the Terengganu Estuary to offshore waters, Malaysia.

    Spatiotemporal microplastic occurrence study of Setiu Wetland, South China Sea
    (Elsevier, 2021) Yusof Shuaib Ibrahim; Siti Rabaah Hamzah; Wan Mohd Afiq Wan Mohd Khalik; Ku Mohd Kalkausar Ku Yusof; Sabiqah Tuan Anuar
    This study reports the distribution of microplastics (MPs) in surface water and estuarine sediments in South and North Setiu Wetland in the South China Sea. Sampling was conducted bimonthly for one year from November 2016 to November 2017, including the northeast and southwest monsoons. Water surface and sediment samples were collected from six different sampling stations (STs). Samples were sorted based on physical analysis (optical observation) and selected particles were further analyzed by chemical characterizations.

    The degradation and toxicity of commercially traded vegetable oils following spills in aquatic environment
    (Elsevier, 2022) Arularasu Muthaliar Tamothran; Kesaven Bhubalan; Sabiqah Tuan Anuar; Jonathan M. Curtis
    The production of commodity and specialty vegetable oils is increasing every year to fulfill the ever-increasing demand where the trading of oils occurs primarily via sea shipping. Spills of vegetable oil into the aquatic environment may result in detrimental effects on aquatic ecosystems. Environmental degradation of vegetable oil spills occurs mainly via microbial activity, chemical oxidation, wave and wind actions. However, the polymerization of oils can hinder their ability to naturally degrade. Thus, human intervention in the form of both short- and long-term remediation, is desirable to reduce the effects of vegetable oil spills on aquatic ecosystems.
