Logam Berat Mercury (Hg) dan Arsen (As) pada Hasil Tangkapan Nelayan Pesisir Semarang dan Tegal Jawa Tengah
Summary
This Indonesian study measured mercury and arsenic levels in fish caught by coastal fishers in Semarang and Tegal, finding heavy metal concentrations that highlight contamination risks for communities depending on local seafood.
The Semarang and Tegal coastal waters are traditional fishing ground areas. However, the increasing use of coastal areas for various activities will increase pollutants in the coastal waters. Heavy metals are pollutants that always appear in waters and accumulate in marine organisms. These study aims to determine As and Hg metals contained in the tissues of several marine organisms caught on the coast of Semarang and Tegal, Central Java. The analysis of As and Hg concentrations in organismal tissues using ICPMS. The results showed that As and Hg were found in biota such as white shrimp (P. merguensis), blue crab (P. pelagicus), shellfish (A. inaequivalvis) and gastropods (H. ternatanus). Arsenic concentrations in the four biotas caught in Tegal (1.6 – 5.3 ppm) and Semarang (2.58 – 4.9 ppm). Meanwhile, Hg metal (0.02 – 0.15 ppm) in Tegal and (0.034 – 0.15 ppm) in Semarang. The concentration level of As based on the biota caught in the Tegal waters are sequentially Shellfish > White shrimp > Gastropods > Blue swimming crab. Meanwhile, the concentration of Arsenic in the biotas in Semarang waters are sequentially shellfish > white shrimp > blue crab > gastropods. However, Hg metal in the biota obtained in these two areas is very low Pesisir Semarang dan Tegal merupakan daerah penangkapan perikanan tradisional. Namun dengan semakin meningkatnya pemamnfaatan wilayah pesisir untuk berbagai kegiatan akan meningkatkan polutan dalam perairan. Logam berat merupakan polutan yang selalu muncul dalam perairan dan terakumulasi organisme laut. Penelitian ini bertujuan untuk mengetahui logam As dan Hg yang terdapat dalam jaringan beberapa biota yang ditangkap pesisir Semarang dan Tegal Jawa Tengah. Analisa konsentrasi As dan Hg dalam jaringan organisme menguunakan ICPMS. Hasil penelitian menunjukan logam As dan Hg ditemukan dalam biota seperti udang putih (P. Merguensis), rajungan (P. pelagicus), kerang bulu (A. inaequivalvis) dan gastropoda (H. ternatanus). Konsentrasi Arsen di keempat biota yang ditangkap di Tegal (1,6 – 5,3 ppm) dan Semarang (2,58 – 4,9 ppm). Sedangkan logam Hg (0,02 – 0,15 ppm) di Tegal dan (0,034 – 0,15 ppm) Semarang. Tingkat konsentrasi logam As berdasarkan biota yang tertangkap di perairan Tegal secara berurutan Kerang bulu > Udang putih > Gastropoda > Rajungan. Sedangkan konsentrasi Arsen dalam biota di perairan Semarang secara berurutan Kerang bulu > Udang putih > Rajungan > Gastropoda. Namun logam Hg dalam biota yang didapat di kedua daerah tersebut sangat rendah.

Konsentrasi Logam Berat Timbal (Pb) dan Tembaga (Cu) pada Hasil Tangkapan Nelayan Pesisir Semarang dan Tegal Jawa Tengah
This study measured lead (Pb) and copper (Cu) concentrations in fish caught by coastal fishermen in Semarang and Tegal, Central Java, Indonesia. Heavy metals were detected in fish tissues, reflecting contamination in the coastal waters. Since microplastics can adsorb and concentrate heavy metals before being ingested by fish, they may amplify the metal burden in seafood consumed by local communities.
Residual Levels of Mercury, Cadmium, Lead and Arsenic in Some Commercially Key Species from Italian Coasts (Adriatic Sea): Focus on Human Health
Researchers assessed mercury, cadmium, lead, and arsenic levels in two commercially important fish species from the Adriatic Sea, finding that while individual metal concentrations were generally below safety thresholds, cumulative exposure from high fish consumption may pose health risks.

Not a microplastics paper — this study measures heavy metal concentrations (nickel, zinc, copper, lead, cadmium) in marine fish from the Persian Gulf and assesses the associated human health risk from fish consumption.
Bioconcentration of Heavy Metals in Milkfish Reared in Stick-Net Pens System: Implications for Open Water Environmental Contamination and Food Safety
Researchers measured concentrations of heavy metals including chromium, cadmium, copper, and lead in both the coastal waters and milkfish meat at stick-net pen cultivation sites in Tanjung Mas, Semarang City, Indonesia. The study assessed bioconcentration of these metals in farmed milkfish and the implications for food safety and open water environmental contamination.
Kontaminasi Logam Cr dan Fe pada Organisme Benthik Laut yang Ditangkap di Perairan Jawa Tengah
This Indonesian study measured chromium and iron contamination in benthic marine organisms from coastal waters near industrial areas in Central Java. While focused on heavy metals, industrial coastal areas are also significant sources of microplastic pollution, and benthic organisms accumulate both types of contaminants.
