Coal mining activities openly cause the formation of mine pits and are currently used by the community for fish farming. This research aims to determine the histopathological status of gills, heavy metal content (Pb, Cd, and Fe) in tilapia fish (Oreochromis niloticus) and water bodies ponds. Samples were taken by purposive sampling technique at four locations with different ages, namely Senong Pit (5 years), Goldstar Pit (10 years), Bendang Galactic Pit (15 years) and Control. Measuring heavy metal content was carried out using AAS. Fish gills are processed by the paraffin method and hematoxylin-eosin staining. The results of the analysis of the heavy metal content of Pb, Cd, and Fe in surface water in all ponds are below the Class II Water quality standard based on the Provincial Regulation of East Kalimantan No. 02 of 2011. The value of heavy metal concentrations in sediments is higher than in water. Pb content in Tilapia (O.niloticus) meat from all ponds is between 2.92 to 4.41 mg / kg, while Cd is between 0.02 to 0.03 mg / kg. The Pb metal content status of the results of this study is above the limit of heavy metal contamination determined by BPOM Decree No. 5 of 2018 which is 0.02 mg / kg, while the heavy metal Cd is still below the specified limit of 0.10mg / kg.The total content of Fe metal ions in fish meat is 83.64 sd 144.92 mg/kg bw These results indicate the total content of Fe ions is far above the safe limit standard for the presence of Fe contaminants in all food sources based on FAO / WHO (2011) of 0.8 mg/kg. Fish originating from all post-mining pond ages indicate damage to the histological structure gills which are characterized by damage to epithelial cells, changes in secondary lamella structures characterized by hyperplasia, destruction of secondary lamella structures and filaments, lamella aneurism and secondary lamella fusion. The results showed that histopathologically and bioaccumulation of heavy metals in fish meat from post-mining ponds showed unhealthy conditions

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 paper presents the results of compost tests from home composters and earthworms living there, that treating waste into compost. The samples were taken from home composters and allotment gardens from Opole Region. The composting material was green waste. The total content of heavy metals (Cd, Pb, Cu, Zn, Ni Cr) in compost and compost earthworms’ samples were determined. It was found that the compost samples were not contaminated with heavy metals. According to the Polish classification of composts from municipal wastes, the composts met the requirements for first class of quality. The composts did not exceed the limits of heavy metals specified in the Polish law for solid organic fertilizers. The degree of metal accumulation by compost earthworms depended on the type of metal. The high value of the bioaccumulation factor (BAF) was obtained for Cd, Pb and Zn. No accumulation of other metals (Ni, Cr, Cu) in earthworm bodies was found. It has been found that earthworm species, naturally occurring in Poland, can also be used as potential bioindicators of metals in the environment, such as the species Eisenia fetida. The aim of the study was to evaluate the heavy metal content in composts from home composters and ability to accumulate metals by compost earthworms.

To date, environmental issues become increasingly prominent, especially heavy metal (Pb and Zn) pollution of soil. This paper describes the procedure of detecting heavy metal content in soil from Zhuzhou Smelting in order to understand the contamination degree of heavy metals. An extensive soil survey was conducted in the plant include lead and zinc major production areas. Microwave digestion and ICP-AES technology were used to test metal content in soil. The results revealed that the soil in the area had been polluted by Pb and Zn, however, the pollution degree of each type of metals was not identical. In general, the Smelting was slightly polluted by heavy metals, with the highest concentration being in the Zinc sulfide plant. The heavy metal content in deep soil was a little bit higher than surface except for the Zinc sulfide plant. The reason may related to its particular location.

The aim of this study was to evaluate heavy metal content in carrots (Daucus carota) from the different localities in Serbia and assess by the cluster analysis (CA) and principal components analysis (PCA) the heavy metal contamination of carrots from these areas. Carrot was collected at 13 locations in five districts. Chemometric methods (CA and PCA) were applied to classify localities according to heavy metal content in carrots. CA separated localities into two statistical significant clusters. PCA permitted the reduction of 12 variables to four principal components explaining 79.94% of the total variance. The first most important principal component was strongly associated with the value of Cu, Sb, Pb and Tl. This study revealed that CA and PCA appear useful tools for differentiation of localities in different districts using the profile of heavy metal in carrot samples.

Present studies were conducted on the study of heavy metal content of three popular freshwater fish, tilapia Oreochromis niloticus, shing, Heteropneustes fossilis and pangus, Pangasius sutchi collected from pond and open water in Mymensingh. All samples were evaluated by studying unwanted heavy metal concentrations. Cadmium (Cd) concentration (μg/g) of pond water O. niloticus, H. fossilis and P. sutchi was found to be 0.21±0.02, 0.20±0.01 and 0.22±0.02 respectively and open water was 0.28±0.03, 0.25±0.02 and 0.29±0.03, respectively. Copper (Cu) concentration (μg/g) of pond water O. niloticus, H. fossilis and P. sutchi was 0.25±0.02, 0.29±0.03 and 0.21±0.02 respectively whereas open water had 0.28±0.01, 0.59±0.04 and 0.35±0.01 respectively. Lead (Pb) concentration (μg/g) of pond water O. niloticus and H. fossilis contained 0.07±0.01 and 0.08±0.01, respectively whereas the open water had 0.15±0.02 and 0.15±0.01, respectively. Pb concentration both in pond and in open water P. sutchi was nil. Pb concentration of O. niloticus was higher in open water fishes (0.15±0.02 μg/g) than the fishes of pond water (0.07±0.01 μg/g). Heavy metal concentration of O. niloticus, H. fossilis and P. sutchi was within permissible limits except Cd of open water fishes. The result revealed that open water fishes have higher concentration of heavy metals in their muscle than the fishes of pond water. The results indicate that the open water environment is polluted by various chemical composition as well as various toxic heavy metal pollutants.Res. Agric., Livest. Fish.5(1): 117-126, April 2018

Increased consumer awareness of heavy metal content in virgin and post-consumer recycled polymers for direct food-contact packaging has necessitated developing analytical methods that identify and quantify heavy metals. Two common acid digestion methods incompletely digest polyethylene terephthalate samples and, thus, additional methods are required to properly analyze polyethylene terephthalate. This study developed two modified microwave-assisted acid digestion methods resulting in complete polyethylene terephthalate digestion, which subsequently produced visually clear solutions. Inductively coupled plasma-optical emission spectrometry analysis of the completely digested polyethylene terephthalate resulted in heavy metal concentrations statistically higher for lead and antimony than for the methods that did not completely digest the polyethylene terephthalate polymer. This study indicates that previously published research results might have unintentionally created bias toward lower heavy metal contamination in polymers used for food packaging. This is of concern when considering end-of-life disposal for food packaging with regulatory threshold levels for specific and total heavy metal content.

Monitoring of heavy metal content (Pb, Hg, Cd) in biomass of water plants (algae, mosses, macrophytes) and sediments had been carried out in the Dyje/Thaya River basin during 1992-1994. Heavy metal content was investigated in all the more abundant species or groups of plants in 14 localities along the entire Dyje/Thaya River. High heavy metal concentrations were also measured in sediments and in algal water bloom (Cyanophyta) in Vranov and Nové Mlýny Reservoirs. A substantial part of lead, mercury and cadmium contamination in the Dyje/Thaya River basin has its origin in the non-point sources of pollution such as atmospheric deposition, application in agriculture of mineral fertilisers containing trace elements, preservation of cereal grains before planting with mercury agent until 1990, etc. Despite the fact that atmospheric deposition of lead from traffic emissions has been decreasing, in 1992-1994 it represented probably the largest source of lead in the Dyje/Thaya River basin.

Removing bottom sediment from water reservoirs and rivers can, on the one hand, be an effective method to restore lakes, and on the other - be used for plant production, ensuring the recycling of nutrients. The aim of this research was to evaluate the possibilities of using various types of bottom sediment and its impact on heavy metal content in soil and plants. For this purpose, a pot experiment was carried out using white mustard (Sinapis alba) as a test plant. The total content of heavy metals (Cd, Cu, Zn, Pb) was determined in soil and plant. The addition of all types of bottom sediment increased heavy metal content in the soil. The results indicate that adding bottom sediment resulted in a significant increase in plant yield in comparison to the control. The highest yield as a result of direct effect was obtained for a combination with a 5% addition of dam sediment, while as a result of residual effect, the highest yield was achieved for a mixture with a 10% addition of pond sediment. The values of the transfer factor (TF = Cplant/Csoil) indicate a high accumulation of zinc and low accumulation of lead in the plant.

Aims: To investigate the level of heavy metal contamination in the lettuce cultivated in Place: Savadkooh County in Mazandaran, Iran. Methodology: five samples were taken from the lettuce produced in this area and also from the soils in which they were cultivated, and the concentrations of Nickel, Lead, and Cadmium were measured by atomic absorption spectrometry. Descriptive and inferential statistics were used to analyze the measured data. Data analysis was performed by SPSS ver.16 at the 0.05 significance level. Results: The highest lead concentration, 0.07ppm, was observed in the sample No. 5 (Lettuce 5), the highest cadmium concentration, 0.008ppm, was measured in the sample No. 2 (Lettuce 2), and the highest nickel concentration, 0.07ppm, was observed in the samples No. 1 and 4 (Lettuce 1 and Lettuce 4). Conclusion: The results of this study show that while all the lettuces cultivated in the Savadkooh region contain some amounts of nickel, cadmium, and lead, these amounts are much lower than the limits specified in Iran’s national standard, and therefore these products are perfectly safe to consume. Also, the concentration of each heavy metal in the lettuces was found to be directly correlated with the corresponding concentration in the soil in which they were grown, indicating that the heavy metal content of the products increases with the increasing heavy metal content of the soil.
