Microplastic in Gonggong snails (Laevistrombus turturella) and sediment of Bintan Island, Kepulauan Riau Province, Indonesia

Microplastics (1 um - 5 mm) had been pollutants in marine habitat and can be consumed by fauna. This study aims to determine the number of microplastic particles found in sediments and Gonggong snails Laevistrombus turturella in four station at coastal areas of Bintan Island. Ten snails were taken,...

Description
Summary:Microplastics (1 um - 5 mm) had been pollutants in marine habitat and can be consumed by fauna. This study aims to determine the number of microplastic particles found in sediments and Gonggong snails Laevistrombus turturella in four station at coastal areas of Bintan Island. Ten snails were taken, and its sediment collected at a depth of 1-2 cm from the surface as much as ± 250 gr. The tissue of gonggong snails were destructed on HNO3 for 24 hours and diluted 10 times with 50% NaCl solution before observed under a light microscope. Our findings at four stations showed the average number of microplastics concentration in the snail presence at Madong Village (492 ± 107.68 particles/ind.), Pengudang Village (476 ± 171.34 particles/ind.), Busung Village (360 ± 118.43 particles/ind) and Kawal Village (628 ± 191.93 particles/ind) wet weight. Microplastics concentration in the sediment at Madong Village (956 ± 171.18 particles/kg), Pengudang Village (928 ± 118.58 particles/kg), Busung Village (604 ± 119.26 particles/kg) and Kawal Village (1,136 ± 154.75 Particles/kg). Our observations also showed many plastics waste on the coastal area.
