Abstract

Cockles Anadara antiquata (Linnaeus,1758) have important economic value on the Bintan Island. The clam is consumed by many people both local people and tourists. The cockles can be found in coastal areas and are epifauna, causing the organism to be highly susceptible to contamination with pollutants such as microplastics. This study aims to determine the number of microplastics in the cockles from the coast of Bintan Island, Riau Islands. We collected samples of the clam, seawater and sediment from four stations. This research showed 100% of the sample contained microplastics. Microplastic types found are fiber, film and fragments. The average number of microplastics was found in the cockle, water and sediment were 496 ± 98,63 particle/ind, 12,3 ± 2,8 particle/liter and 16.580 ± 3.727,5 particle/kg respectively. Station 4 was recorded the highest amount of microplastic (650 ± 82,98 particle/ind). Based on the correlation test, the number of microplastics in the clam correlated with the mass of the clam. Correlation was shown between the microplastics in the cockle and water, and also sediments and there was a correlation between the microplastics in the water and the sediments.
