Analisa Cemaran Logam Merkuri Pada Ikan Air Laut Dan Udang Secara Spektrofotometri Serapan Atom (Ssa)

Abstract

Mercury is a heavy metal that can have a toxic effect on the body so it can cause death. Mercury metal contamination in food is regulated in SNI number 7387 of 2009 regarding the Maximum Heavy Metal Limit. Some metal waste disposal ends up in rivers, lakes, or sea waters so that metal pollution can occur in the ecosystem. This study aims to determine levels of mercury metal contamination in seawater fish, including shark, mackerel, salmon, tuna, red snapper, and white shrimp. Sample preparation was carried out by wet digestion method using a microwave digestion device. Mercury analysis was carried out using the AAS (Atomic Absorption Spectrophotometry) method. The wavelength used is 253.7 nm. The results showed that mercury in sharks was 0.2045 ± 0.0099 mg/kg, mackerel 0.4184 ± 0.0297 mg/kg, salmon 0.3848 ± 0.0794 mg/kg, tuna fish 0.3706 ± 0.0674 mg/kg, snapper 0.4088 ± 0.0397 mg/kg, and shrimp 0.4289 ± 0.0813 mg/kg. The results of the analysis showed that of the six samples of seawater fish that had been tested, the maximum metal contamination limit determined by SNI 7387 the Year 2009 was 0.5 mg/kg.

Literature Review: Overview of Heavy Metal Contamination of Shrimp in Indonesia

“…Hasil Uji merkuri pada udang menunjukkan hasil negatif merkuri yakni tidak ada perubahan warna pink kebiruan/keunguan atau bisa dikatakan kadar merkuri <0,5 mg/kg. Penelitian uji merkuri menggunakan metode kualitatif (Uji warna/Rapid Test Kits) maupun metode kuantitatif (AAS (Atomic Absorption Spectrophotometer)) (Dewi, 2022), (Silalahi, Marpaung and Supartiningsih, 2020), (Zuhairiah, Sitompul and Elly, 2019).…”

Analisis Unsur Logam Berat Kadmium pada Kerang Darah di Pasar Tradisional Kota Lhokseumawe

“…Kadmium dapat menyebabkan nefrotoksisitas (toksik pada ginjal), yaitu dengan beberapa gejala proteinuria, glikosuria, dan juga aminoasidura yang disertai dengan penurunan laju filtrasi glomerolus pada ginjal. SSA (Spektofotometri serapan atom) merupakan salah satu metode analisis kandungan logam berat berupa kadmium dimana pada pengukurannya berdasarkan penyerapan cahaya dengan Panjang gelombang tertentu oleh atom logam dalam keadaan bebas (Pitaloka, 2019).…”
