Analysis of Heavy Metal Content of Copper (Cu) in Milkfish (Chanos chanos Forsk) from Milkfish Farms in Bima Bay 2020

Abstract

Fish are aquatic organisms and are often used as biological indicators of heavy metals in waters, because fish belong to the highest trophic level and their nature is to settle in certain habitats. This research aims to explore the Cu content in milkfish from the Bima Bay milkfish aquaculture to determine the copper content in milkfish from the Bima Bay milkfish aquaculture. The usefulness of this research is to provide information on the Cu content of milkfish aquaculture in Bima Bay. This research was conducted for four months, starting from February - June 2021. Sampling was carried out by purposive sampling at 2 location points with three repetitions. Samples were analyzed at BLKPK NTB Province using the Atomic Absorption Spectrophotometry tool. The results showed that the Cu Content in Palibelo ranged from 0.814 mg/kg (ppm) to 0.915 mg/kg (ppm), so that an average of 0.856 mg/kg (ppm) was obtained. Meanwhile, the Cu Content in Melayu ranged from 0.351 mg/kg (ppm) to 0.441 mg/kg (ppm), so that an average of 0.387 mg/kg (ppm) was obtained. The average total Cu content in milkfish in the Bima Bay area is 0.621 mg/kg (ppm). Based on these results, it can be concluded that the Cu content in milkfish meat from milkfish aquaculture in Bima Bay is 0.621 mg/kg (ppm). The content is very far below the threshold according to the Regulation of the Dirjen POM No.03725/B/SK/VII/89 which is 20 mg/kg so that it is safe for consumption by the public.

Analysis of cadmium heavy metal content in rice snail (Pila ampullacea) from Rawa Taliwang Lake

“…On rice snails obtained from rice fields in the Rancaekek District area that Cu levels in each sample of rice snails (65.7 mm/kg, 3.5 mm/kg, 6.2 mm/kg, 5 mm/kg, 5.8 mm/kg, 6.2 mm/kg, and 4.9 mm/kg) did not exceed the maximum threshold for metal contamination in a food regulated by the Decree of the Director General of Drug and Food Control No.03725/B/SK/VII/1989) and also safe for daily consumption with a consumption limit of no more than one kilogram per day [11]. Similar results are also in line with [28] research but in different aquatic biota; it was found that there was a heavy metal Cu content in milkfish flesh of 0.621 mg/kg from Bima Bay milkfish farms. The Cu content is still below the threshold according to the Director General of POM Decree No.03725/B/SK/VII/89, which is 20.0 mg/kg.…”

Analysis of Cadmium (Cd) Heavy Metal Content in Mosambique Tilapia Fish (Oreochromis mossambicus) Derived from Rawa Taliwang Lake to Enrich Ecotoxicology Lecture Material in 2022

“…Ikan adalah hewan air yang mempunyai pergerakan cepat sehingga dapat terhindar dari pencemaran, namun pergerakannya terbatas pada habitat tertutup seperti danau (Yusuf et al, 2013). Ikan sering digunakan sebagai indikator biologis logam berat (Yunanmalifah et al, 2021). Jenis ikan yang digunakan sebagai bioindikator adalah ikan mujair.…”

Analysis of Cadmium (Cd) Heavy Metal Content in Headsnake Fish (Channa striata) Derived from Rawa Taliwang Lake, West Sumbawa Regency 2021

“…Ikan dalam rantai makanan di suatu perairan air dapat mengakumulasi logam dari lingkungannya. Apabila ikan yang terakumulasi logam berat dikonsumsi oleh manusia, hal itu dapat berbahaya bagi kesehatan (Cahyani et al, 2016;Yunanmalifah et al, 2021). Ikan yang hidup di danau lebih mudah terkontaminasi oleh logam berat dibandingkan dengan ikan yang hidup di perairan terbuka dikarenakan danau adalah habitat yang terbatas sehingga lebih mudah untuk terkontaminasi (Kahiruddin et al, 2021).…”
