Microplastic Contamination in Waters and Sediments in the Selorejo Reservoir, Malang Regency, East Java
AI summary Read the abstract
This study measured microplastic contamination in water and sediment samples from the Selorejo Reservoir in East Java, Indonesia, finding widespread contamination across all sampling sites. The reservoir serves as a water source for surrounding communities, raising concerns about human exposure through drinking water.
Microplastics are small plastic particles under 5 mm in size that have contaminated a lot of ecosystems, both aquatic and on land. The existence of heaps of garbage and the existence of fishing activities around residential areas are some examples of anthropogenic activities that are on the edge and water bodies of the Selorejo Reservoir. This study aims to observe the contamination of various types of microplastics and their abundance in water and sediment samples taken from the Selorejo Reservoir. Sampling was carried out using the selected method (purposive sampling) at five different stations, including the Konto River inlet, Kwayangan River inlet, settlements (blendrang), tourism areas, and reservoir outlets. Each station has 3 transects (as replicates) and about 100 liters of water and 1000 grams of sediment are taken. Destruction of water and sediments uses 30% H2O2 and 30% H2SO4 acid to remove organic components that are still attached and to facilitate observation under a stereo microscope with 400X magnification. Based on the results of an analysis of the abundance of microplastics in the waters of each station, the highest abundance of microplastics was successively found in the Konto river inlet with a total abundance value of 39.27x101 particles/liter, then in the residential part (blendrang) a number of 35.34x101 particles/liter, tourist areas 33.67x101 particles/liter, outlet 30.36x101 particles/liter and Kwayangan river inlet 29.67x101 particles/liter. Meanwhile, the highest total abundance of microplastics found in sediments in the Selorejo Reservoir was found successively in the Konto river inlet with a total abundance value of 3.68 particles/gram, then in the tourist area 2.08 particles/gram, in the Kwayangan river inlet 1.56 particles/gram, in the residential part (blendrang) a number of 1.2 particles/gram and outlets 1.12 particles/gram. Each type of microplastic is then counted based on the amount found. The results of the identification of microplastic contamination in waters and sediments in the Selorejo Reservoir found several types of microplastics, namely fibers, fragments, filaments, and films. The dominating type and color of microplastic is black fiber.

Analysis of Microplastic Content in Surface Water of the Gajah Mungkur Reservoir in Indonesia
AI summary Read the abstract
Researchers analyzed surface water from Indonesia's Gajah Mungkur Reservoir, a drinking water source, and found microplastics at every sampling location, with concentrations ranging from 340 to 820 particles per cubic meter. The dominant shapes were filaments and fibers, and the plastics identified included polypropylene and polystyrene. The highest contamination was found at an upstream river inlet, suggesting that rivers are a key delivery route for microplastics into the reservoir. The findings raise concerns about microplastic exposure through drinking water drawn from Indonesian surface water sources.

This study analyzed the abundance, type, size, color, and distribution of microplastics in sediments of Selorejo Reservoir in Malang Regency, Indonesia. Fragment-type microplastics (42%) in the 125–250 µm size range (48%) and black color (46%) were dominant, with an overall average abundance of 56,637.5 particles per kilogram of sediment. The highest concentrations were found at the reservoir outlet, and FTIR analysis was used to identify polymer compositions.

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.
