Studies on heavy metal content of Meritrix meritrix and surrounding waters as well as the quality of Banjarmasin waters were done. Observation was carried out in June, August and October 2003 at 6 sampling points, 3 stations were 1 mile while 3 others were 2 miles from coastal line. Distance between stations was approximately 1 mile. The samples collected from each station were hard clam (Meritrix meritrix), sea water and sediment. Heavy metals content, Hg, As, Cd, Cu and Pb, in hard clam and mercury content in sea water and sediment were analyzed by atomic absorption spectrophotometer (AAS). The result showed that Hg content of Banjarmasin waters in June, August and October 2003 were 6.05, 3.17, and 4.91 ppb, respectively, indicated that Banjarmasin waters had been polluted by mercury. Whereas the hard clam in Banjarmasin waters contained Hg (1.91 ppb), As (0.88 ppb), Cd (0.22 ppb), Cu (0.46 ppb), and Pb (0.32 ppb) which were still under the maximum concentration for consumable clam.

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.

Abstract Sea cucumber is a commodity fishery that is traded international. One of the sea cucumber that has economic value is the local sea cucumber (Phyllophorus sp.) believed that contain compounds can be immunomodulatory. Phyllophorus sp. is one of the three dominant species of sea cucumbers in abundance and distribution in the Surabaya East Coast (Winarni,dkk., 2010). Coastal environmental issues that deserve the attention is the problem of heavy metal pollution in coastal waters. The highest toxicity of heavy metals for aquatic animals and humans are mercury (Hg) (Widowati dkk, 2008). The purpose of this study was to determine levels of heavy metals bioaccumulation of mercury (Hg) in the local sea cucumber (Phyllophorus sp.) From the East Coast Surabaya and to determine the heavy metal content of mercury (Hg) in the local sea cucumber (Phyllophorus sp.) has exceeded the threshold or does not. The experiment was conducted on the East Coast Surabaya and analisys of heavy metal Mercury (Hg) in Balai Besar Laboratorium Kesehatan (BBLK) Surabaya. The method used is the method of field observation and analyzed descriptively. The results showed levels of mercury bioaccumulation of heavy metals (Hg) from BCFo-w value from 454.78– 802.05 and BCFo-s from 31,42 – 111,26. This shows Phyllophorus sp. have the ability to accumulate heavy metals with low until middle accumulation level category. Mercury content of the Phyllophorus sp. obtained range from 0.031 to 0.061 ppm, sea water ranged from 0.0015 to 0.0023 ppm and sediments ranged from 0.0417 to 0.112 ppm. Mercury levels in Phyllophorus sp. and sediment is below the NAB, but the sea water has exceeded from NAB. Water quality parameters are still in normal conditions in accordance with the quality standards KMLH (2004) that temperatures 26-28 º C, pH 7-8, salinity ranged from 28-29 ‰, DO value range 4-5 mg / L and brightness between 2-3 m.

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.

In order to investigate the effects of mining pollution to LongJiang River and to know the situation of LongJiang River, we collected water and sludge samples along the river and analyzed the heavy metal content of samples. Results showed that LiDeFen factory and JinHe mining released most of the heavy metals to LongJiang River two years ago, and the upstream of LongJiang River also released some metal to the river. These heavy metals were precipitated to the bottom of LongJiang River by using weak alkaline chemical precipitation technology, and water quality of LongJiang River can reach the second national environmental quality standards of surface water now. The precipitation effects were different in different remediation sites.

<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.
