Summary

Scientists measured microplastic contamination in shellfish living in coral reefs off the coast of Vietnam, finding an average of about 5.6 microplastic particles per individual. Polyethylene and polyamide fragments smaller than 100 micrometers were the most common types found. Since bivalves are filter feeders that people eat whole, these findings mean that consuming shellfish from these reefs involves direct ingestion of microplastics.

Study Type Environmental

This study aimed to assess the presence of microplastics in bottom sediment and bivalve species, including Pinna bicolor, Atrina vexillum, Saccostrea sp., and Pinctada margaritifera, living in coral reefs on Vietnam's Southern coastal. The average microplastic abundance were 0.45 ± 0.13 items/g of wet soft tissue weight or 5.60 ± 1.49 items/individual in bivalve samples and 294 ± 43 items/kg dry weight of sediment samples. The fragment shape, size smaller than 100 μm, and polyethylene, polyamide, cellophane and polyethylene terephthalate were identified as the predominant constituents of the microplastics. The pollution load and potential ecological risk index of microplastics were at a minor level, whereas the polymer hazard index was at a high level. Overall, this study provides a basis for assessing the risks posed by microplastics in the marine ecosystems of Vietnam.
