Summary

Researchers examined four species of commercially important marine fish from waters around Johor, Malaysia, and found microplastics present in the flesh of all species sampled. Fibers and fragments were the most common particle types, with polypropylene and polyethylene being the dominant polymers identified. The findings raise concerns about human dietary exposure to microplastics through commonly consumed fish in the region.

Microplastic contamination in marine ecosystems endangered marine organisms such as fish and poses a risk to humans. This research aims to investigate the presence of microplastic contamination in commercial marine fish caught around Johor, Malaysia. This study uses samples from four species of commercial marine fish consists of Indian mackerel, Yellowtail scad, Forktail threadfin bream and Black pomfret. Furthermore, microplastics were extracted, characterized, and identified from fish flesh. The results show that the fish species with the highest number of microplastics were yellowtail scad (23.33%) and Indian mackerel (30%) from all fish analyzed, which had an average of 0.022 and 0.021 particles/g, respectively. The pelagic fish has a higher microplastic number than the demersal fish (p-value = 0.037). Black fragments with < 200 µm in size are the majority of microplastics discovered. Fish flesh predominantly contains microplastics like polyamide (PA) and Ethylene propylene diene monomer (EPDM). Further study and regular monitoring on microplastic contamination in commercial marine fish need to be done to mitigate the impact of microplastics on human health and marine ecosystems, particularly in Johor, peninsular Malaysia.

Microplasticcontaminationincommercial marine fish: A case study in Johor, Malaysia

Researchers examined microplastic contamination in flesh from four commercial marine fish species (Indian mackerel, yellowtail scad, forktail threadfin bream, black pomfret) from Johor, Malaysia. Pelagic fish species had higher MP concentrations (averaging 0.022 and 0.021 particles/g) than demersal species, with black fragments under 200 µm being the most common particle type.

Microplastic ingestion by commercial marine fish from the seawater of Northwest Peninsular Malaysia

Researchers examined microplastic ingestion by four species of commercially important marine fish caught off the northwest coast of Peninsular Malaysia. The study found microplastics in the gastrointestinal tracts of the fish, with fibers being the most common type, highlighting the prevalence of microplastic contamination in seafood from this region.

Occurrence, distribution and characteristics of microplastics in gastrointestinal tract and gills of commercial marine fish from Malaysia

Researchers examined 158 commercial marine fish from 16 species in Malaysia and found microplastics in the gastrointestinal tracts and gills of all species studied. Fibers were the most common microplastic type, and the contamination levels varied between sampling locations. The findings add to growing evidence that microplastics are widespread in commercially important fish species, raising questions about the potential for human exposure through seafood consumption.

Abundance and characteristics of microplastics in commercial marine fish from Malaysia

Microplastics were found in the digestive tracts of eight commercially important marine fish species caught in Malaysian waters, with prevalence and particle types varying by species and location. The study raises food safety concerns for Malaysian seafood consumers and highlights the widespread occurrence of microplastic ingestion in wild-caught fish from Southeast Asian seas.

Quantification, identification, and chemical characterization of microplastics (MPs) in commercial fishes from the Palk Strait, Southeast India

Researchers examined microplastics in the tissues and guts of 75 commercially important fish from the Palk Strait in Southeast India, finding an average of 115 particles per individual. Fibers were the most common form at 51%, with polyethylene and polypropylene as the dominant polymers, and particle sizes ranged from 0.1 to 1.0 millimeters. The presence of microplastics in edible fish tissues suggests a potential route of human exposure through seafood consumption.
