Microplastics Characteristics in Water and Sediment From Three Ecosystems on Sari Ringgung Beach, Pesawaran Regency, Lampung Province
Summary
Researchers sampled water and sediment across mangrove, seagrass, and coral reef ecosystems at an Indonesian beach, finding microplastic contamination in all three habitats with the mangrove ecosystem showing the highest concentrations — up to 467 particles per kilogram of sediment. Fibers, films, and fragments smaller than 1 mm were the most common forms found, highlighting widespread microplastic pollution across multiple coastal ecosystem types.
Plastic waste that pollutes the ocean will lead a degradation process until it becomes small particles measuring less than 5 mm called microplastics.The durability and microscopic properties of microplastics can have a harmful effect on mangrove, seagrass, and coral reef ecosystems.The purpose of this study was to analyze the microplastics characteristics that found in the water and sediment of the three ecosystems.The study was conducted in August 2024 at Sari Ringgung Beach, Pesawaran Regency, Lampung Province.Samples of water and sediment were taken from three stations representing three ecosystems.According to the results that the mangrove ecosystem had the highest microplastics abundance, namely in water 410 particles/m3, and in sediment 466.67 particles/Kg.Microplastics abundance in the water from seagrass ecosystem was 203.33 particles/m3, and in sediment 360 particles/Kg.Microplastics from the water of coral reef ecosystem had an abundance 283.33 particles/m3, and in sediment 160 particles/Kg.The microplastic contamination found was in the form of fibers, films and fragments.The size of microplastics is dominated by small sizes (<1 mm), except in sediments in the mangrove ecosystem which are mostly large sizes (1-5 mm).The dominant microplastics colors are black, blue, red and brown.Data and information related to the characteristics of microplastics that pollute Sari Ringgung Beach are needed so that they can be managed more optimally and sustainably.
