Assessment of microplastic contamination in some marine species collected in Ba Ria – Vung Tau province
Summary
This study documented microplastic contamination in four commercially important marine species — oysters, green mussels, mullet, and tonguefish — from aquaculture and fishing areas in Ba Ria-Vung Tau Province, Vietnam. Microplastics were found in 100% of samples, with oysters having the highest concentrations. Because these species are widely consumed, the findings highlight a direct pathway for microplastic ingestion by humans via seafood and underscore the need for monitoring in Vietnamese coastal waters.
Recently, there has been increasing interest in studying microplastic pollution because of its dangerous effects on human health through the food chain. This paper presents the first results obtained on microplastic density in some marine species (including oysters, green mussels, mullet and tonguefish) cultured in Ba Ria – Vung Tau Province. The results indicated that microplastics were present in 100% of the analyzed samples with different concentrations in the order: oysters (10.3 ± 1.5 microplastics/individual) > blue mussels (7.4 ± 0.7 microplastics/individual) > mullet fish (4.1 ± 1.3 microplastics/individual) > tonguefish (1.2 ± 0.9 microplastics/individual). There are four main types of plastic found in the digestive organs of marine species including Polypropylene, Polyethylene Terephthalate, polyethylene, and polystyrene.
