Hubungan Mikroplastik dan Kualiti Air di Sungai Melaka, Melaka, Malaysia
AI summary Read the abstract
Researchers surveyed microplastic abundance and physicochemical water quality across nine stations in the Melaka River, Malaysia, finding an average concentration of 569 particles per liter. Black fragments of polyamide (PA) and polyethylene terephthalate (PET) dominated, with total suspended solids correlating with fiber microplastic levels.
Sungai Melaka adalah sumber pendapatan utama bagi masyarakat di negeri Melaka telah tercemar oleh mikroplastik. Penyelidikan ini bertujuan untuk mengkaji kelimpahan dan ciri mikroplastik yang dijumpai di dalam sampel air daripada 9 stesen pensampelan di sepanjang Sungai Melaka. Kualiti air dan perhubungan antara mikroplastik dengan sifat fizikokimia kualiti air juga dianalisis dalam kajian ini. Purata kelimpahan mikroplastik di Sungai Melaka adalah 569 zarah L-1. Mikroplastik warna hitam dan bentuk serpihan merupakan ciri-ciri mikroplastik yang dominan. Poliamida (PA) dan polietilena tereftalat (PET) adalah jenis polimer yang banyak dijumpai di dalam semua sampel air. Jumlah pepejal terampai (TSS) ditemui sebagai parameter yang mempunyai pengaruh terhadap mikroplastik gentian di Sungai Melaka. Secara keseluruhan, keputusan ini memberi maklumat terkini mengenai pencemaran mikroplastik di Sungai Melaka dan menyediakan data penting untuk penyelidikan lanjut mengenai mikroplastik dalam ekosistem air tawar.

AI summary Read the abstract
Researchers surveyed microplastic contamination along an urban-to-rural gradient in Malaysia's Klang River and found widespread pollution across all six sampling stations, with HDPE, LDPE, polypropylene, and nylon fibers and fragments dominating — patterns pointing to urban runoff and industrial discharge as primary sources entering the Malacca Strait.
Analysis of the Relationship Between Microplastic Abundance and the Presence of Plastic Waste in the Mahakam River, Muara Kaman District
AI summary Read the abstract
Indonesian-language research linked the abundance of plastic debris in the Mahakam River to the concentration of microplastics in the water, confirming that larger plastic waste is a direct source of microplastic contamination in this river system. The study supports the importance of plastic litter control as a strategy to reduce microplastic pollution.
Abundance and Distribution of Microplastics in the Water and Riverbank Sediment in Malaysia – A Review
AI summary Read the abstract
Microplastic abundance and distribution were surveyed in the water column and riverbank sediments of a Malaysian river. Results showed microplastics throughout the river system, with fiber shapes dominating in water and fragments more common in sediments, reflecting contributions from domestic wastewater and plastic litter.
