Summary

Microplastic abundance in seawater and coastal sediments from two East Java sites differed significantly — Surabaya (north coast) showed 2,100 particles/m³ in water vs. 170 particles/m³ in Tulungagung (south coast) — with fragment and fiber types dominant at both sites.

Study Type Environmental

This research attempted to determine the abundance and characteristics, including morphology, color, and size of microplastics found in coastal sediment and seawater of Wonorejo, Surabaya, which is located on the north coast of East Java, and Popoh, Tulungagung on the south coast of East Java. Water and sediment samples were collected during the dry season with two replications. The standard method of water sample laboratory preparation and microplastic identification was carried out using NOAA Technical Memorandum NOS-OR&R-48, while the sediment sample was prepared with several modifications. The average microplastic abundance in Surabaya and Tulungagung seawater samples is equal to 2100 particles m-3 and 170 particles m-3, respectively. Meanwhile, as many as 740 particles kg-1 and 350 particles kg-1 were found consecutively in sediment samples of Surabaya and Tulungagung. Microplastics in seawater samples were dominated by 44.7% red and 80.9% fiber, while 43.1% black and 51.4% fiber microplastics were primarily found in sediment samples. The microplastic size ranges from 30—1450 μm in seawater samples and 50—3750 μm in sediment samples. Keywords: abundance, characteristics, microplastics, seawater, sediment.
