The Musi River is the main route for community activities in Palembang City, which makes it vulnerable to plastic pollution, including microplastics. The Juaro catfish (Pangasius polyuranodon), a food fish found in this river, is likely to ingest microplastic particles through its digestive tract. The study was conducted from December 2024 to February 2025 at two locations: Musi 2 and 13 Ulu Ta…
Cerithidea quadrata (suction snail) is a gastropod species from the Sungsang coastal area and is a marine biota that has potentially toxic secondary metabolite compounds. The presence of this species in the Sungsang coastal area is quite dominant compared to other species so that it has great potential to be utilised as a medicinal material. The research was conducted to analyse the toxicity le…
Sungsang is a water area in Banyuasin Regency, South Sumatra, where tthe majority of the community earns their livelihood from fishing. Gulamah fish is characterised by its yellow fins. The purpose of this study was to measure and compare the concentration of Cd metal in the flesh, liver, and gills of Gulamah fish as well as to assess the Cd metal content in humans after consuming Gulamah fish …
Heavy metal lead, commonly found in industrial waste, is toxic to aquatic organisms. Its presence in water can harm organisms such as climbing perch. Lead can cause liver damage, close the gill membrane, and even lead to death in fish. Additionally, it can cause reproductive disorders, inhibit vitellogenin induction, delay oogenesis, increase hormone secretion, and decrease gonadal somatic inde…
