Analysis of Microplastics on Digestive and Respiration System of Horse-Eye Jack Fish (Caranx latus) in Coastal Bungus Bay, West Sumatra
AI summary Read the abstract
Researchers analyzed microplastic contamination in the digestive and respiratory systems of Horse-Eye Jack fish from Bungus Bay, West Sumatra. Microplastics were found in all fish samples, with fibers being the dominant shape and particles smaller than 0.5 mm being most common, indicating widespread microplastic exposure in this coastal marine ecosystem.
Microplastic pollution accumulates in the marine environment, thus impacting the health of marine organisms. The purpose of this study was to analyze and identify the abundance and characteristics of microplastics in Horse-Eye Jack fish (Caranx latus) in coastal Bungus Bay, West Sumatra. Fish samples were taken at three different locations, namely, Sako beach, Caroline Beach, and the east side of Bungus Bay. The average abundance of microplastics in horse-eye Jack fish samples in digestive is 21.63 ± 3.99 particles/fish, and in respiration, 9.23 ± 1.92 particles/fish. The shape identified forms of microplastics are fibers, films, fragments, granules, and foam, and the dominant color of microplastics is red. The most common size of microplastics found was <0.5 mm. FT-IR spectroscopy analysis showed that the polymer types of microplastics found were PE, PVC, PET, and PS. Statistical tests showed differences between the abundance of microplastics in two pathways of microplastic uptake (digestive and respiration), and the sampling location P<0.05. The results showed that microplastics were found in all Horse-Eye Jackfish samples in Bungus Bay, West Sumatra.These findings highlight microplastics' harm to the marine ecosystem and the necessity of managing plastic waste if we hope to avoid future plastic pollution catastrophes

Microplastic Contamination of Four Important Commercial Fish in East Coast of North Sumatera Province, Indonesia
AI summary Read the abstract
Researchers identified and characterized microplastic pollutants in the gastrointestinal tracts of four commercially important fish species (Johnius borneensis, J. macropterus, Osteomugil engeli, and Sardinella fimbriata) collected from the east coast of North Sumatra Province, Indonesia between May and December 2022. The study quantified microplastic types, shapes, and colors across multiple sampling sites and species to assess contamination levels in these economically significant fisheries.

Microplastic Occurrence in Different Fish Organs from Two Coastal Waters in Java Sea, Indonesia
AI summary Read the abstract
Researchers assessed microplastic accumulation in the gut and gill tissues of six economically important fish species from Jakarta Bay and Cirebon Bay in Indonesia. They found microplastics present in all samples, with variations in abundance and polymer type across species and locations. The study raises concerns about the potential transfer of microplastics to human consumers through commercially harvested fish in the Java Sea region.
The presence and physico-chemical properties of microplastics in seawater, sediment, and several organs of the spotted scat fish (Scatophagus argus, Linnaeus, 1766) collected from different locations along the East Java coast in Indonesia
AI summary Read the abstract
Scientists examined microplastic contamination in seawater, sediments, and spotted scat fish along the East Java coast in Indonesia. Microplastics were found in every sample, including in the fish's gills, stomach, and intestines, with fibers being the most common type. Since these fish are consumed by local communities, the presence of microplastics throughout their organs raises questions about human dietary exposure through Indonesian seafood.
