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.

Soils and water bodies near auto mechanic village (MV) contain heavy metals, which pollute the environments and are hazardous to human and environmental health. Assessment of heavy metal concentration in three replicate soil and water samples from three MVs (Fajol, Id-Aba and Kotopo) in Abeokuta metropolis in Nigeria was conducted. Heavy metal concentrations in topsoil of the MVs showed copper ranging from 0.02 mgkg-1 in the topsoil at Idi-Aba MV to 126.89 mgkg-1 for topsoil at Kotopo MV. The level of copper detected in Kotopo MV soil is however higher than the allowable limits for Sweden, Netherlands and Germany. Mean concentration of zinc in soils of the MVs were 2.89, 0.91 and 86.23 mgkg-1 respectively for Fajol, Idi-Aba and Kotopo MV respectively. Metal enrichment factor indicated that the contamination degree ranged from unpolluted to moderately polluted areas. Copper is the most enriched metal in the soil of the MVs especially at Kotopo MV. Relative abundance of the metals in the topsoil (0-15cm) in Fajol MV follow the order Zn > Ni> Cr >Pb >Cu > Co> Cd.  For the Idi-Aba MV, relative abundance is in the order Ni > Zn > Cr > Pb> Cu > Co and Cd, and that of Kotopo MV was Cu >Zn> Pb > Ni > Cr, Co and Cd. Mean heavy metal in the water samples were lower than those found in the soils of the MVs. Stream water near the Kotopo MV had the highest concentration of most metals. Zinc had the highest mean concentration of 2.02 mgL-1 while copper was 1.09 mgL-1.  There is an urgent need to put measures in place to monitor the activities in these MVs in order to safeguard peoples’ health environmental integrity.

<div> <p>This paper present migration of some selected heavy metal (zinc, lead, copper, chromium and nickel) of roadside soil samples from along Ilesa-Akure highway with a view to assess the degree of contamination such soils contain and the likelihood that this contamination can be remobilized. Soil samples were collected from 5 locations (Ilesa, Ipetu-ijesa, JABU, Ilara-mokin and FUTA north gate) at depths of 0-5, 15-20, 35-40 and 55-60cm and analysed for the five selected heavy metals in the bulk sample and clay fraction. Their concentrations and distributions in four different road verge zones (5m, 30m, 60m and 110m) were determined. The 5m zone had the highest mean concentration of the five metals whereas the 110m zone exhibited the lowest mean concentration. Zinc and lead exhibited a significant decrease in the roadside soils with the increasing distance from the road while chromium and nickel showed significant increase, copper on the other hand showed no significant difference. Quantitative assessment of the heavy metal contamination using the I<sub>geo </sub>and <em>PI</em> indexes showed that the selected heavy metals were in the order of Cu &lt; Pb &lt; Zn &lt; Ni &lt;Cr for both Indexes. Soil characteristics (which include pH, Cation exchange capacity {CEC}, organic matter and other basic geotechnical tests) responsible for the mobility and vertical distributions of these heavy metals from the road side soil were also assessed.</p> </div> <p>&nbsp;</p>

Heavy Metals In Soils

The aim of the study was to determine the source for contents of heavy metals in soils of landfill sites in Ulaanbaatar. Samples were collected from ash of the burned waste near the landfill sites to identify content of heavy metals such as plumbum, chromium, cadmium, nickel and zinc. There are total of 300 mg/kg chromium and 700 mg/kg zinc identified from ash of burned electrical wire, 1000 mg/kg plumbum is identified from the ash of burned tires. According to the comparison of heavy metal contents in landfill sites, landfill of industrial waste has higher content rate of chromium and cadmium than other landfill sites. These open burnings and industrial waste have considerable influences on contaminated soil with heavy metals. This is not only a source for soil contamination but also a risk to air and water pollution or resident health. Therefore, it is indispensable to develop waste management for human health and environmental protection.

The physicochemical properties and the concentrations of heavy metals of water samples collected from four different rivers of Nkanu east and west Local Government Areas of Enugu of state Nigeria were investigated because of the prevalent water borne diseases in these localities attributable to the drinking of contaminated water. The water samples were collected from different sites of Esu, Umuekwe, Umuobeagu and Atafu rivers and their physicochemical properties and heavy metal contents were measured. Sampling Stations were selected; samples were collected avoiding contamination from the selected sites in same season, from same depth. On site measurement of parameters was done with the same instruments. Rests of the parameters were measured in Laboratory. Lead (Pb) was present in Esu, Umuekwe, Umuobeagu and Atafu rivers at a concentration of 0.14, 0.03, 0.00 and 0.16 mg/L respectively; Zn was only detected in Esu and Umuobeagu at 0.07 and 0.01 mg/L respectively and cadmium (Cd) concentrations of 0.14, 0.14. 0.08 and 0.08 mg/L respectively. Iron was detected in only Umuekwe river having 0.17 mg/L and Atafu river having 0.21 mg/L while Ni was detected at 3.01, 4.20, 1.20 and 3.83 mg/L respectively. Only Atafu river had Cr at 0.01 mg/L, only Esu river had Co content at 0.05 mg/L, Mn content in Esu, Umuekwe, and Umuobeagu was found to be 0.01, 0.02 and 0.02 mg/L respectively with Atafu river having none. Hg concentration was found to be 0.57, 0.06, 0.42 and 0.82 mg/L for Esu, Umuekwe, Umuobeagu and Atafu rivers respectively. The concentrations of Pb and Cd were higher in all the four samples especially in Esu river as a result of its closeness to construction sites and refuse dump and the concentrations were above the acceptable limits of WHO standard of 0.010 and 0.005 mg/L respectively for drinking water while Hg, Fe, and Ni were found within the W.H.O limits of 0.001, 3.000 and 0.100 mg/L respectively. The rest were below the standard, thus confirming conclusively that the rivers are polluted with the presence of heavy metals.

Introduction: Contaminated water is linked to diseases worldwide. Aims: To investigate the heavy metals concentration in underground water around the Solous dumpsite in Igando Lagos State, Nigeria and its effect on human. Materials and Methods: water samples from 12 different locations within a distance range of 0.07 - 0.72 km was collected. And a structured questionnaire was administered to 120 respondents to find out their perceptions about the dumpsite environment and ill-health effect of their drinking water. The physicochemical parameters was measured and heavy metals concentration of the water samples were determined using Flame Atomic Absorption Spectrometer. Results: The water samples from the 12 sites contains heavy metals concentrations: Lead (Pb) (0.08-1.20mg/L), Cadmium (Cd) (0.03-0.08mg/L), Iron (Fe) (1.4-12.3mg/L), Nickel (Ni) (0.08-0.19mg/L), Zinc (Zn) (0.05-0.13mg/L) and Manganese (Mn) (0.01-0.04mg/L) respectively. It was revealed that age, educational qualification and year of living in the community of the respondents explain a significant amount of the variance in the value of the perception of the respondents on effect of heavy metal contamination. The result shows that over 75% of the respondents was not sure of any prior ailment linked to any heavy metal contamination affecting anyone among them. Conclusion: all water samples collected were contaminated by heavy metals and respondents using this water are ignorant of the danger. Thus, there is a need for proper provision of safe alternative water supply to the dumpsite community for domestic use and awareness on environmental heavy metal toxicity from drinking water to avert global health challenges.

Abstract The study was conducted to investigate heavy metal contents namely, Iron (Fe), Copper (Cu), Zinc (Zn), and Manganese (Mn) from surface sediment and water samples collected from the Ujjani Reservoir. The concentrations (mg kg− 1) of Fe, Cu, Zn and Mn in sediment detected were 4455.0, 184.05, 97.4, 1090.5 respectively, while in water metal contents (mg l− 1) Fe, Cu, Zn, and Mn were 3.05, 0.5, 0.82, and 2.56 correspondingly. The contents of metals in the studied samples showed a descending order such as Fe, Mn, Zn and Cu. It was observed that the mean concentrations of Fe, Cu, and Mn were more in sediment and water, whereas, Zn contents were detected lesser than the standard levels proposed by USEPA 2004. The sediment pollution analysis was achieved using a Pollution load index (PLI), Geoaccumulation index (Igeo) and Potential ecological risk index (RI). Similarly, risk of metals in water was evaluated using Average absorption dose (ADD), Hazardous quotient (HQ), and Hazardous index (HI). In our study, the ADD, HQ and HI values for metals were lower than 1, indicating that there is no health risk associated with studied heavy metals present in surface water. Also sediment quality assessment shows that there is minor ecological risk of studied heavy metals. Even though, the Ujjani Reservoir has a lower ecological risk, its water and sediment quality is declining day by day. Therefore, there is a need to make a policy for ecological restoration to avoid further damage to the ecosystem and human beings.
