Investigation of Microplastic Contamination in Sediments, Water and Aquatic Biota in Lake Beratan, Tabanan Regency, Bali Province – Indonesia
Summary
This study detected microplastics in sediments, water, and aquatic organisms from Lake Beratan in Bali, Indonesia, finding contamination across all sample types in this tourist and agricultural area, with fiber and fragment morphologies dominant across a range of polymer types.
Microplastics (MPs) has become a very serious global threat, especially to the health of animals, humans and the environment. In this study we aim to investigate the contamination of MPs in sediment, air, and aquatic biota collected from the waters of Lake Beratan in Bali Province, Indonesia. Lake Beratan is one of the strategic areas that continues to develop as a tourist destination, agriculture and fisheries, as well as a source of water for daily needs.Sediment, water, and aquatic biota samples were collected from 4 stations that represent the Beratan Lake area. Each sample obtained was then followed by the pre-treatment stage using 5 M NaCl solution. Furthermore, the extraction process for each sample used wet oxidation peroxidation (WPO) with the addition of Fe (II) catalyst. The highest average weight of MPs in the sediment samples was obtained at the 1st sampling point of 2.53% which was dominated by soft fragments. The percentage of MPs weight in the water samples was varied at each sampling point with the highest obtained at the 4th point of 99.2% and was dominated by hard-shaped fragments at all sampling points. The collected aquatic biota (fish and shrimp) was also contaminated by MPs of 68% in fish and 36.40% in shrimp. The types of MPs found in the digestive tract of aquatic biota are in the form of fragments, filaments, films and foam. These results indicate that the aquatic environment of Lake Beratan, Bali has MPs content that varies in sediment, water and aquatic biota which are often consumed by the local community. This must be of particular concern and further investigation, especially regarding the environmental management of the lake area and the relevant authorities in formulating regulations to reduce the harmful effects of MPs contamination.

Microplastic Abundances in the Sediment of Coastal Beaches in Badung, Bali
Microplastics were found in sediment at all five coastal beaches studied in Badung, Bali, with fibers dominating and concentrations varying significantly between sites. Bali's status as a major tourist destination and its coastal pollution levels raise concerns for both marine ecosystems and the many visitors exposed through swimming and seafood consumption.
Spatial and temporal trends of microplastic contamination in surface sediment of Benoa Bay: An urban estuary in Bali-Indonesia
Researchers examined microplastic contamination in sediments of Benoa Bay, an urban estuary in Bali, Indonesia, across rainy and dry seasons. The study found concentrations ranging from 9.51 to 90.60 particles per kilogram, with the highest levels near a landfill site, and polyethylene, polypropylene, and polystyrene were the most commonly identified polymers.
Microplastic Pollution in Waters and Sediments in a Lentic System: A Case Study in a Tropical Wet Urban Lake of Samarinda, Indonesia
Researchers sampled water and sediment from a tropical urban lake in Samarinda, Indonesia, finding microplastic contamination at all 10 sampling sites with an average of 0.91 particles per litre in water and 375 particles per kilogram in sediment. Fibres — likely from textiles — dominated in both water and sediment, and polyethylene was the most common polymer identified. The study highlights how urban lakes in rapidly developing tropical cities are becoming significant repositories of microplastic pollution, driven by inadequate waste management infrastructure.
