Urban lakes had significantly higher microplastic concentrations than rural ones, with fibers being the most common particle shape across all sites. The study provides one of the most comprehensive assessments of freshwater microplastic pollution in India, revealing that even relatively remote lakes are not free from contamination.
Research status and prospects of microplastic pollution in lakes
This review systematically covers microplastic pollution research in lakes, including sampling and identification methods, distribution patterns, ecological effects, and knowledge gaps, identifying lakes as important but understudied sinks for microplastic contamination.
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.
Plastic pollution in freshwater ecosystems: macro-, meso-, and microplastic debris in a floodplain lake
Researchers surveyed macro-, meso-, and microplastic debris in a South American floodplain lake and found an average of 704 microplastic particles per square meter in sediments, with plastic contamination comparable to marine beaches — demonstrating that freshwater lakes can be major plastic pollution reservoirs.
Microplastics in surface water of Laguna de Bay: First documented evidence on the largest lake in the Philippines
Microplastics were detected for the first time in the surface water of Laguna de Bay, the largest lake in the Philippines, at all ten sampling stations. Fibers were the dominant type, consistent with textile sources, and concentrations varied across the lake. The study establishes the first baseline data on microplastic contamination in a major Philippine freshwater body.
