Abundance of microplastic in green mussel Perna viridis, water, and sediment in Kamal Muara, Jakarta Bay

Abstract

Research on the abundance of microplastic in green mussel Perna viridis, water and sediments in Kamal Muara, North Jakarta in September 2017 has been done. The research determined the abundance of microplastic in water, sediment and green mussel (base on the sizes and microplastic storage organs), also the correlation between abundance of microplastic in green mussel, water and sediments. Samples of green mussel, water and sediments were taken from 3 different stations with a distance of about 500 meters. Analysis of abundance of microplastic was done by isolating microplastic in each sample. The isolation of the green mussel samples was done by dissolving the mussels in the HNO3 solutionfor 24 hours and added saturated NaCl solution. The microplastics from water and sediment samples were separated by immersion of samples in a saturated NaCl solution. The results obtained were, on average, abundance of microplastic in green mussel size 3, 6, and 9 cm i.e., 5.35; 24.99; and 39 particles/gram. The microplastic fiber was dominant in mussel sample. The average abundance of microplastic in water and sediment are 13.15 particles/L of sea water and 0.92 particles/gram of dry sediment respectively. The microplastic film was dominant in water and sediment samples. Meanwhile, pellet was not found in all three samples. There was a correlation between abundance of microplastic with green mussel size, as well as with abundance of microplastic of film and fiber in water and sediment.

Microplastics in wild clams harvested from coastal waters of Lamongan, Indonesia

“…Compared to the abundance reported in other studies (Table 2), G. tumidum in this study had much lower microplastics content than in Pari Island, Jakarta, Indonesia (13.44 to 17.33 items/individual, 9.1 items/g) [52]. In Jakarta Bay, other bivalve species, Perna veridis, were also found to contain a high number of microplastics, 5.39 to 39 items/g [53], while the total average of microplastics concentration from all bivalve species from the Lamongan coast was only 3.2 ± 2.52 items/g. Pari Island is located in Jakarta Bay.…”

Microplastics characteristics of lorjuk Solen sp. in east coastal waters of Surabaya

“…The samples of lorjuk were collected ±5 cm shell lengths respectively. The length of this shell was chosen as a representation of the size of consumption and the average adult size of lorjuk found on Kenjeran Beach [11] [12]. The lorjuk shell was measured using a caliper.…”

“…Water samples were taken at each point of the research station to see the microplastic content. Microplastics are obtained from sea water filtered using a plankton net [12]. The mesh size of the plankton net used is 100 μm [14].…”

“…Sediment samples were taken at a depth of 5 cm from the surface using a trowel. Sediment taken is 0.5 kg per station [12]. Sediment samples were stored in stainless steel from each station [15].…”

Occurrence and distribution of microplastics in the beach sediment of Anday Beach, West Papua (Indonesia)

“…These small particles are available to be ingested by various organisms. The marine mammals such as whales, dolphins and seals [9], sea turtles [10], marine birds [11], crustaceans [12][13]; fish [14][15][16][17][18]; sea cucumber [19][20]; bivalves [21][22][23]; plankton [24][25][26] have been reported to be affected by microplastic debris.…”
