dc.description.abstractMicroplastic pollution in freshwater ecosystems is an emerging environmental concern due to its persistence, widespread distribution, and ecological risks. This study investigates the sources, distribution, and ecological risks of microplastics in the surface waters of the Pinang River (Balik Pulau) and Kerian River (Nibong Tebal), Malaysia. These two rivers are subjected to varied land uses, including agriculture, aquaculture, and urban development. The study integrates historical water quality data (2017–2021), in-situ measurements, stereomicroscopy, FTIR polymer identification, and ecological risk assessment through the Risk Quotient (RQ) method. To identify potential pollution sources, secondary water quality data were analyzed using Principal Component Analysis (PCA), revealing that both rivers are predominantly impacted by diffuse sources such as agricultural runoff, aquaculture effluents, and domestic discharges.
