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.

Abstract The urbanization is regarded as the major factor related to human activities that may interfere with the natural ecosystem. In this study, we have selected the wetland of East Dongting Lake as the research area. We have collected 180 soil samples (within the range of 0–20 cm, and 20cm-40cm), and we have measured the contents of their physicochemical properties (including salinity, pH value, soil particle composition, soil organic carbon, nitrate nitrogen and rapidly available phosphorus) as well as heavy metal elements (including As, Hg, Cd, Pb, Ni and Cr). We have adopted the methods of multivariate statistical analysis and inverse distance weighted (IDW) interpolation, so as to to reveal the sources and distribution characteristics of heavy metal content in soil in the research area. By adopting the potential ecological risk index (PERI) method proposed by Hakanson, we intend to assess the PERI values of heavy metals. Our research findings have shown that: (1) 8 sorts of heavy metals have shown positive correlation with each other. As, Hg and Zn have shown a significantly positive correlation with SOC (P < 0.01); As, Ni, Cr and Zn have shown a significantly positive correlation with AP (P < 0.01); As and Pb have shown a significantly positive correlation with Clay (P < 0.01); whereas Hg and Zn have shown a significantly negative correlation with Silt (P < 0.01); As and Pb have shown a significantly negative correlation with Sand (P < 0.01). (2) During urbanization, the elements of Cd, Ni, As, Hg and Pb might be enriched due to agricultural and industrial activities, whereas the use of fertilizers and pesticides constitute one of the major factors contributing to the increase of Cd and Pb contents in soil. (3) Influenced by the varying land patterns and with exception to Cu, the Fe-normalized concentrations have shown significant variations among different types of land use (P < 0.05). Specifically, there is a significantly higher level of Cd, Zn, Pb and Hg contents in the agricultural land than other types of land use, whereas there is a slightly higher level of heavy metal content in the mudflats than that in the grassland. In addition, the content of heavy metals in woodland remains relatively stable, and with exception to As, the content of heavy metals in woodland is the lowest among the five types of land. (4) The average value of the comprehensive PERI in heavy metals amounts to 555.03, representing a strong degree of ecological risks. Specifically, the proportion of sampling points of Cd that have a high level of ecological risks amounts to 36.51%, which is the primary element contributing to heavy metal pollution in the region, especially in the agricultural land.

The environmental effects of mining and its impact on natural resources are of a holistic nature. One of the modern methods employed for the remediation of technogenically disturbed soils is the application of microorganisms. This paper studies the impact made by soil microorganisms on the accumulation rate of heavy metals in the substrate of waste rock dumps in the process of soil reclamation. Suspensions of soil microorganisms (microorganisms utilising mineral nitrogen forms / MUMN; microorganisms decomposing silicates / MDS; microscopic fungi / MF) were applied to the rock dump surface. Separate groups as well as their combinations were applied. The heavy metal content analysis did not indicate a significant exceedance of the maximum allowable concentration limits (MACL) in the soil of the waste rock. The only metal whose content exceeded the maximum admissible concentration limits was nickel. It has found that the application of microorganisms influences the concentration of several heavy metals due to pH level changes of the rock dump soil.

Determination of  heavy  metal  content  (Hg, Pb, Cd, Cu, Cr, Zn) in some seafoods collected from  Muara  Angke  Fish  Auction  Place  were carried out during February to July 1979. The results showed  that Zn  content  in seafoods a nalyzed  was always much higher than the other heavy metals. The concentration levels of  the  six  heavy  metals observed were low. It is almost of the same level as the metal concentration of  other  seafoods  observed  in various parts of the world oceans, but still lower  than the maximum standard set  for human  consumption  as  established  by   Tasmania, Australia and  World Health Organization. The  mean  per capita  consumption of  fish  in Jakarta is only  about 165 g  per week, while  the  Provisional Tolerated Weekly Intake for Hg, set by WHO/FAO at 300 ug level, would be attained by consuming 1500 g Rastrelliger sp., or 698 gPenaeus setiferus, or 545 g Sepia sp., and or 1250 g Pecten sp.  Therefore,  at   present the  level of metal content in fishes sold at TPI  Muara  Angke  can be  considered  as  not  dangerous  to human health as long as these quantities are not surpassed.

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
