Analysis of Microplastic Contamination on Water and Sediment in the Brantas Subwatershed of the Malang Area
This Indonesian study (published in Bahasa Indonesia) analyzed microplastic contamination in both water and sediment of the Brantas River sub-watershed in the Malang area, one of the most important river systems in East Java. Microplastics were found in both water and sediment samples across sampling locations, with fibers being a dominant form. The Brantas River supports millions of people for drinking water and irrigation, making evidence of microplastic contamination in this system a significant public health and environmental concern.
Identifikasi Dan Kepadatan Mikroplastik Di Sekitar Muara Sungai Banjir Kanal Barat Dan Banjir Kanal Timur, Kota Semarang, Jawa Tengah
