Penelitian Lingkungan dan Kebencanaan Geologi Kelautan Perairan Teluk Jakarta (Tanjung Kait – Muara Gembong) dilakukan pada bulan Oktober - November 2010. Uji logam berat (Cu, Pb, Zn, Cd, dan Cr) dilakukan terhadap 28 contoh air laut dan 28 contoh sedimen dasar laut menggunakan metoda Atomic Absorption Spectrophotometry (AAS). Tujuan penelitian ini adalah untuk mendapatkan data dan informasi kondisi lingkungan terkini dari kandungan logam berat dalam air laut dan sedimen dasar laut. Kandungan logam berat (air laut dalam mg/l : sedimen dasar laut dalam ppm) terukur sebagai berikut : Cu ( <0.005 : 15.000-169.500 ); Pb (0.005-0.011 : 14.000-58.100); Zn (0.005-0.007 : 95.800-333.000); Cd (0.006-0.015 : 0.012-0.750); Cr (<0.001 : 45.320-139.180). Berdasarkan Metode Storet dapat dilihat nilai status mutu air laut perairan ini adalah -12, berarti bahwa kualitas air laut di perairan termasuk kelas C (tercemar sedang). Sedangkan status mutu sedimen di perairan menunjukkan skor nilai status mutu sedimen adalah 0, yang berarti bahwa kualitas sedimen termasuk kelas A (tidak tercemar/memenuhi baku mutu). Jelas terlihat bahwa nilai ambang batas (NAB) logam berat dalam sedimen jauh lebih tinggi dari NAB logam berat dalam air. Kata kunci: logam berat, sedimen dasar laut, air laut, nilai status mutu Marine Environmental and Geological Hazard Survey In Jakarta Bay Waters (Tanjung Kait - Muara Gembong) conducted in October-November 2010. Testing of heavy metals (Cu, Pb, Zn, Cd, and Cr) performed on 28 samples of sea water and 28 subsurface sediment samples using the method of Atomic Absorption Spectrophotometry (AAS). The purpose of this study was to obtain data and information on current environmental conditions of heavy metal content in seawater and subsurface sediment. Heavy metal content (sea water in mg/l: subsurface sediment in ppm) measured as follows: Cu ( <0.005 : 15.000-169.500 ); Pb (0.005-0.011 : 14.000-58.100); Zn (0.005-0.007 : 95.800-333.000); Cd (0.006-0.015 : 0.012-0.750); Cr (<0.001 : 45.320-139.180). Based on the Storet method shows the value of water quality status of sea waters is -12, which means that the seawater quality in these waters belong to a class C (medium contaminated). While the status of sediment quality in these waters indicate subsurface sediment quality score status value is 0, which means that subsurface sediment quality belongs to the class A (not polluted/correspond to the quality standards). It is clearly seen that the threshold value (NAV) of heavy metals in sediments is much higher than the NAV of heavy metals in water. Keywords: heavy metal, subsurface sediment, seawater, quality score status

Kebutuhan bahan pangan sangat tergantung pada ketersediaanya di lingungan. Bahan pangan yang diperlukan untuk memenuhi kebutuhan sehari-hari harus sehat dan bebas dari bahan pencemar, termasuk logam berat. Ikan kakap putih (Lates calcarifer) sering dijumpai pada kawasan muara sungai di hampir seluruh wilayah Indonesia, bahkan di Papua. Tujuan penelitian ini adalah untuk mengkaji kandungan logam berat Pb, Cd, Cu, Fe, As, dan Hg pada ikan kakap putih (L. calcarifer) yang hidup di perairan estuari Mimika Papua. Perairan estuari di Mimika diketahui sebagai salah satu daerah pengendapan pasir sisa tambang (tailing). Metode yang digunakan adalah survei dan analisis laboratorium kandungan logam berat pada tubuh ikan. Analisis Pb, Cd, Cu, Fe, As, dan Hg ditentukan dengan spektroskopi serapan atom (AAS, Atomic Absorpsion Spectroscopy). Penentuan tingkat pencemaran logam berat dilakukan dengan Metode Standar APHA 3113 Cetac Technologies SPR IDA. Analisis data dilakukan dengan membandingkan kandungan logam berat dalam air dengan baku mutu air laut menurut SK MNLH No. 51 tahun 2004. Untuk kandungan logam berat pada organ tubuh ikan dibandingkan dengan kandungan maksimum logam berat berdasarkan SNI 7387: 2009 tentang batas maksimum cemaran logam berat bahan pangan. Kandungan logam berat pada ikan kakap putih masih tergolong aman dikonsumsi karena mengandung logam berat di bawah ambang batas baku mutu. Kondisi ini didukung oleh hasil analisis logam berat pada air yang menunjukkan masih dalam kondisi baik.   Kata kunci: L. calcarifer, logam berat, Sungai Kamora, Sungai Ajkwa, Mimika.   The need for food depends on the availability in the environment. Foods needed to meet daily needs should be healthy and free of pollutants, including heavy metals. White snapper (Lates calcarifer) is often found in the estuary of the river in almost all parts of Indonesia, even in Papua. The purpose of this research is to study the heavy metal content of Pb, Cd, Cu, Fe, As, and Hg on white snapper (L. calcarifer) which live in Mimika Papua estuary waters. The estuary waters of Mimika are known as one of the deposition areas of tailings sand. The method used is survey and laboratory analysis of heavy metal content in fish body. Analysis of Pb, Cd, Cu, Fe, and Hg was determined by Atomic Absorption Spectroscopy (AAS). Determination of the level of heavy metal contamination was done by Standard Method of APHA 3113 Cetac Technologies SPR IDA. Data analysis was done by comparing the heavy metal content in water with sea water quality standard according to SK MNLH No. 51 year 2004. For heavy metal content in fish body organs compared with maximum content of heavy metals based on SNI 7387: 2009 on the maximum limit of heavy metal food contamination. The content of heavy metals in white snapper is still considered safe for consumption because its below the quality standard threshold. This condition is supported by the results of heavy metal analysis on the water which shows still in good condition. Key words: L. calcarifer, heavy metal, Kamora River, Ajkwa River, Mimika.

Water samples of six sampling sites (two downstream, two abattoir sites and two upstream sites) were analyzed using standard methods to determined and assessed heavy metal content of abattoir effluent on surface water quality of River Katsina-Ala, Benue State, Nigeria for rainy and dry seasons. Rainy season heavy metals results were; Cr6+ (0.032+0.06mg/l); Mn2+ (0.16+0.034mg/l); Cu2+ (0.86 +0.46mg/l); Pb2+(0.006+0.002mg/;Cd2+(0.0023+0.004mg/l) and the dry season results were: Cr6+(0.028+0.007mg/l); Mn2+(0.07+0.05mg/l); Cu2+(0.85+0.16mg/l); Pb2+(0.0030+0.014mg/l); Cd2+(0.0021+0.012mg/). Most heavy metals for both seasons were within the maximum permissible limit set by Federal Ministry of Environment, Nigeria (1991). The mean concentrations of Zn2+(1.70+0.29 mg/l) for rainy season and Zn2+(1.33+0.23mg/l) dry season were above the control and standard safe limits of < 1mg/l FMEnv (1991) for surface water quality. There was no significance difference (p<0.05) between the means from upstream and downstream sites for both seasons; though significance difference (p<0.05) existed at the abattoir sites. River Katsina –ala is slightly polluted. Heavy metal content from effluents from abattoir contributed to upset the physicochemical balance of the river. Bioaccumulation and bio-magnification of heavy metals may occur from prolong usage of the river water for drinking. It is suggested that the abattoir effluent be treated before discharge into the river to reduce environmental and health hazards.
