Kelimpahan Mikroplastik Pada Kolom Air Dan Lambung Ikan Di Danau (Oxbow) Lubuk Siam Desa Lubuk Siam Kecamatan Siak Hulu Kabupaten Kampar Provinsi Riau
Abstract
Microplastics originated from degraded plastic materials may be flown to water body and accidentally swallowed by aquatic organisms. A research aims to understand the microplastics in the water body and in the stomach of fish living in the Lubuk Siam lake was conducted from September to November 2020. Samplings were conducted 3 times, once/ month, in 3 sampling points. In each sampling point, 100 L of water was taken and filtered using a plankton net (60 μm mesh size). To obtain the microplastics, the filtered water was again filtered using Whatman filter paper No.42 and the type of microplastics were identified using a binocular microscope. The fish used for the microplastic identification consist of 39 fishes, consisting of Notopterus notopterus, Thynnichthys thynnoides, Barbonymus schwanenfeldii, Helostoma temminckii, and Ompok hypophthalmus. The microplastics in the fish stomach was obtained by destroying the organic materials using 10% KOH solution and the microplastics present were identified using a microscope. Results shown that the types of microplastics found in the water and in the fish stomach were similar, namely fibers, films and fragments. The microplastic density was 10 fibers/m3, 93.33 films/m3 and 40 fragments/m3 in the water. While the abundance of microplastics found in the fish stomach ranged from 0.14 to 4.50 particles/fish. The highest abundance of microplastics was found in the O. hypophthalmus stomach (4.50 films/fish). Data obtained indicate that the most common type of microplastic found in the waters and in the fish stomach was film.
