Microplastic in Gonggong snails (Laevistrombus turturella) and sediment of Bintan Island, Kepulauan Riau Province, Indonesia
AI summary Read the abstract
Microplastics were detected in both sediment and Gonggong snails at four coastal sites on Bintan Island, Indonesia, indicating contamination of the local marine food web. The results suggest organisms in this area are ingesting microplastics from their environment.
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.

Identification of the Types and Abundance of Microplastics in Telescopium telescopium in the Coastal Waters of Karimun Island, Riau Islands Province
AI summary Read the abstract
Researchers identified and quantified microplastics in telescope snails (Telescopium telescopium) from coastal waters in Karimun Island, Riau Islands, and examined whether snail size affected microplastic accumulation. The study found microplastic contamination in all sampled snails, demonstrating that benthic invertebrates in this region are exposed to plastic particles.

Evidence of Microplastics Accumulation in Selected Marine Molluscs for Consumption in The Meranti Islands of Riau Indonesia
AI summary Read the abstract
Researchers found microplastics — primarily fibers — in all four species of edible marine molluscs sampled from the Meranti Islands in Indonesia's Riau region, with larger individuals ingesting more plastic. Since these shellfish are consumed whole by local communities, microplastic contamination in them represents a direct pathway for human exposure through seafood.
