Analysis location of microplastics in green mussel’s Perna viridis Gills (Linnaeus, 1758)

Abstract This study describes the location, type, and range of microplastic sizes found in the gills of green mussel Perna viridis. This study continues the results of Fathoniah’s research on 2017 about microplastic abundance in green mussels at Kamal Muara, North Jakarta. Sample of 3 green mussels with a size of about 7 cm was taken from Kamal Muara. Gills from both the outer and inner demi branch were isolated and made as preparations. Every part of the gills marked into posterior, anterior, proximal, and distal. After that, the gills were observed under the light optical microscope. Position and type of microplastic in the gills was recorded and measured using the LAZ EZ application. The results showed that the distal area of the gill contains more microplastic than proximal. The dominant microplastic group found in the gills of green mussels was fiber. The range of microplastic sizes found in green mussel’s gills was 20-4500 μm.
