Identification of microplastics content in milkfish (Chanos chanos), water and sediment in ponds in Muncung Village, Kronjo District
Summary
Researchers analyzed microplastic abundance and characteristics in milkfish (Chanos chanos), water, and sediment at six stations in Muncung Village ponds, finding fragments, fibers, and films with the highest abundance in intestinal tissue, and FTIR analysis identifying six polymer types including ABS, PVC, PP, and EVA.
Plastic is a product that is currently popular among people, but over time plastic can be dangerous for the environment. Plastic can degrade into smaller particles known as microplastics. Microplastics in waters can harm aquatic biota such as fish. The size of microplastics is so small that it easily enters the fish's body, settles in the digestive tract and affects the fish's life cycle. Apart from biota, microplastics also pollute water and sediment. The aim of this research is to determine the abundance of microplastics and identify the characteristics of microplastics in milkfish in ponds in Muncung Village. The method used is take fish from ponds at 6 stations along with water and sediment. The fish were dissected and the digestive organs and flesh were removed, while the water and sediment were treated with NaCl. The microplastics found will be tested by FTIR to determine the polymer. The results of the observations showed that there were 3 types of microplastics, namely fragments, fibers and films. The highest abundance in organs was in the intestine, while microplastics were also found in water and sediment. FTIR test results show 6 plastic polymers in milkfish, namely ABS, latex, PVC, PP, EVA and nitrile. Keywords: Microplastics, milkfish, FTIR, Muncung Village

Researchers identified microplastics in the digestive tracts of 24 milkfish (Chanos chanos) collected from aquaculture ponds in Pedaleman Village, Indonesia, finding fragments as the most abundant type followed by fibers and films, with FTIR analysis identifying polymers including polyethylene, PTFE, PMMA, and nylon.
Identification of Microplastics Content in Sediment, Water and Digestive Channel of Milkfish (Chanos chanos) in Sidoarjo Pond
Researchers quantified microplastics in sediment, water, and the digestive tracts of milkfish (Chanos chanos) from semi-intensive and traditional ponds in Sidoarjo, Indonesia. Microplastic abundance was higher in traditional pond sediments (613 particles per 50 g versus 300 in semi-intensive ponds), and fish from traditional ponds contained more particles (9.5 per individual versus 6), with polyamide being the dominant polymer type.
