| Abstract | Microplastics, as plastic fragments less than 5 millimeters (mm), are a global environmental concern that can provide a primary risk related to food contamination. Shellfish are marine organisms that are commonly subjected to microplastic contamination. The objectives of this study were to investigate microplastic contamination in spotted babylon (Babylonia areolata) and green mussels (Perna viridis) from supermarkets, local markets, and wholesale shops in Lampang province, Thailand. The results showed that spotted babylon and green mussels from the wholesale shop had the highest number of contaminated microplastics, with 1.67 ? 2.89 and 0.67 ? 0.58 particles/g wet weight, respectively. The average number of microplastics in the spotted babylon and green mussels were 0.89 ? 0.69 and 0.44 ? 0.19 particles/g wet weight, respectively. However, the number of microplastics was not significantly different among supermarkets, local markets, and wholesale shops (p > 0.05), and there was no significant difference between spotted babylon and green mussels (p > 0.05). The average length of microplastic particles found in spotted babylon and green mussels was 0.13 ? 0.14 and 0.12 ? 0.07 mm, respectively. The predominant fragment shape of microplastics found in spotted babylon and green mussels were 100.00% and 66.67%, respectively. The dominant colors of the microplastics found in spotted babylon and green mussels were blue (50.00%) and black (66.67%), respectively. The major microplastics detected were polypropylene (PP) in spotted babylon; PP and polyethylene terephthalate in green mussels. These polymers are commonly used in protective packaging and containers. Therefore, the findings of this study recommended microplastic prevention policies, especially regarding fishing and aquaculture sources. These policies could include monitoring the concentrations of microplastics in both wild and farmed seafood, encouraging circular design for fishing, evaluating the hazards and effects of microplastics on consumers, marking and tracking fishing gear to discourage discarding and facilitating the recovery of missing gear, and requiring the reporting of lost fishing and aquaculture gear to public authorities. |
