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.

The present study was conducted to figure out the heavy metals (Cd, Co, Cu, Fe, Hg, Mn, Mo, Ni, Pb and Zn) concentrations in water, sediments and fish species from the Rupsha River, Khulna, Bangladesh to spot the heavy metal contamination level. Heavy metals are dangerous because they're non-biodegradable and having an extended half-life period. The heavy metal contamination could also be an excellent concern, especially for aquatic life. The metal concentration within the water sample from the Rupsha River was significantly above the rule values of WHO and USEPA respectively. Moreover, the concentration of metal within the sediments was also greater than the respective probable effect concentrations of the sediment quality guidelines. Furthermore, consistent with the fish standards, these studied fish species weren't found to be contaminated by heavy metals. It’s concluded that each of the heavy metals from the whole sample didn't exceed the standard maximum level. This study demonstrated that water of Rupsha River isn't safe for aquatic organisms also like humans in terms of Pb, Cd and Cr contents as accumulated through consumption.

Background: Heavy metals are materials naturally occurring in nature and increase with a rise in human activity. Ex-mining areas and domestic waste from human settlements are sources of heavy metal contamination that enter and pollute water, which then accumulates in various organisms including the Caulerpa racemosa community. The accumulation of heavy metals in C. racemosa has a wide impact on the food chain in aquatic ecosystems and humans because this alga is a consumptive commodity.   Methods: Sampling of C. racemosa was carried out at seven sites on Bintan Island, Indonesia covering the eastern (Teluk Bakau, Beralas Pasir, Malang Rapat), northern (Berakit and Pengudang), western (Sakera), and southern parts (Tg. Siambang). Sampling was carried out during different monsoons, and heavy metals in water and sediment samples were measured to determine the heavy metal concentration. Heavy metals were analyzed by a spectrophotometric method using Atomic Absorption Spectrophotometry.   Results: The results showed that heavy metal concentrations fluctuate according to changes in the wind season, which carry currents and spread pollutants into the water. The concentration of metal in the water is also from anthropogenic activities. The heavy metal content of cadmium (Cd), lead (Pb), copper (Cu), iron (Fe), and zinc (Zn) in C. racemosa is high in locations close to settlements. Meanwhile, in seawater samples, Fe and Zn metals have the highest concentrations compared to others.  Conclusions: Ex-bauxite mines are a source of Fe and Zn metal contamination in the environment, especially at Tg. Siambang. The levels of these heavy metals in the sediment are also high, as surface particle deposits accumulate at the bottom of the sediment. In general, the levels of heavy metals Cd, Pb, Cu, Fe, and Zn increase in the northern monsoon because the dynamics of the water transport greater heavy metal pollution.

<strong>Heavy Metal Contamination in the Coastal Area of Tanjung Selor North Kalimantan.</strong> The establishment of the North Kalimantan Province transformed the Tanjung Selor region and its surroundings into the provincial capital so that it will grow rapidly, both in terms of development and other activities. Monitoring environmental conditions, one of which is heavy metals in the waters need to be carried out as a starting environment before the area develops. This is important given the nature of heavy metals that change toxic at concentrations that exceed the threshold. The purpose of this study is to identify the potential for heavy metal contamination in the coastal area of Tanjung Selor, Bulungan Regency, North Kalimantan Province. Heavy metals studied is limiting to mercury (Hg), Chromium (Cr), Arsenic (As), Cadmium (Cd), Copper (Cu), Lead (Pb) and Zinc (Zn). The location of the sampling was carried out using Landsat 8 imagery designed to represent the condition of the coastal area. Samples come from well water, river water, seawater, and marine sediments at 4, 9 and 5 observation stations respectively. Samples were taken on August 2014  using the grab sample method and analyzed for heavy metal content using the standard American Public Health Association (APHA) method with the Atomic Absorption Spectroscopy (AAS) instrument. Of the 23 samples produced, only 3 observation stations were not contaminated with heavy metals. While in the other 20 samples one of three types of heavy metals were found that exceeded the threshold. In general, Cu is the most detected metal exceeding the threshold in the study area found in samples of river water, sea water and sediment. Zn is found to exceed the threshold in well water. Pb is found to exceed the threshold in sample 5 of river water. Cd is found to exceed the threshold in samples of river water, sea water and sediment. The source of pollution is thought to originate from coal mining activities, oil palm plantations, and household waste. The overall results of this study show that river estuaries tend to accumulate heavy metals.

Abstract: Soil is a major and important natural resource, which not only supports human life but also furnish commodities for ecological and economic growth. Ecological risk has posed a serious threat to the ecosystem by the degradation of soil. The high-stress level of heavy metals like chromium, copper, cadmium, etc. produce ecological risks which include: decrease in the fertility of the soil; reduction in crop yield & degradation of metabolism of living beings, and hence ecological health. The ecological risk associated, demands the assessment of heavy metal stress levels in soils. As the rate of stress level of heavy metals is exponentially increasing in recent times, it is apparent to assess or predict heavy metal contamination in soil. The assessment will help the concerned authorities to take corrective as well as preventive measures to enhance the ecological and hence economic growth. This study reviews the efficient assessment models to predict soil heavy metal contamination.

Resource Reutilization

Heavy metals accumulate in high water table coal mining subsidence ponds, resulting in heavy metal enrichment and destruction of the ecological environment. In this study, subsidence ponds with different resource reutilization methods were used as study subjects, and non-remediated subsidence ponds were collectively used as the control region to analyze the heavy metal distributions in water bodies, sediment, and vegetation. The results revealed the arsenic content in the water bodies slightly exceeded Class III of China’s Environmental Quality Standards for Surface Water. The lead content in water inlet vegetation of the control region and the Anguo wetland severely exceeded limits. Pearson’s correlation, PCA, and HCA analysis results indicated that the heavy metals at the study site could be divided into two categories: Category 1 is the most prevalent in aquaculture pond B and mainly originate from aquaculture. Category 2 predominates in control region D and mainly originates from atmospheric deposition, coal mining, and leaching. In general, the degree of heavy metal contamination in the Anguo wetland, aquaculture pond, and fishery–solar hybrid project regions is lower than that in the control region. Therefore, these models should be considered during resource reutilization of subsidence ponds based on the actual conditions.

Contamination Of Soils

As a result of accidental spills or leaks, industrial wastes may enter in soil and in streams. Some of the contaminants may not be completely removed by treatment processes; therefore, they could become a problem for these sources. The use of synthetic products (e.g. pesticides, paints, batteries, industrial waste, and land application of industrial or domestic sludge) can result in heavy metal contamination of soils.
