This area, which is located near the Banten Bay, is quite active with anthropogenic activities such as industry, fisheries, settlements, and shipyards that have the potential to pollute the environment with heavy metals. This study aims to determine the chemical environmental conditions of the waters and the concentration of heavy metals in the sediments of Banten Bay. Sediment samples were taken at five stations consisting of river and bay sections in April, May, July, August, and September 2019. Heavy metal content in sediments was analyzed according to APHA 2012 using hydrochloric acid and nitric acid destruction methods. The results of heavy metal concentrations in sediments were compared with ANZECC 2000 regulations and sediment quality was determined using the Geo-accumulation Index. The sediment at the observation site is dominated by the silt fraction. The concentration of heavy metals in this study was obtained in the form of lead (Pb) ranging from <0.05 to 6.408 mg / Kg, copper (Cu) ranging from 0.059 to 8.791 mg / Kg, and cadmium (Cd) ranging from 0.042 to 0.605 mg / K. While based on The level of heavy metal contamination in sediments using the Geo-accumulation index (I Geo), the value of all metal types in each month has a value <0.000 at all observation stations. Thus it is concluded that the concentration of heavy metals in the sediment is lower than the threshold determined during the observation. So that the metal concentration weight in the sediment has no significant effect on the environment.

This study attempted to analyze the distribution and contamination status of heavy metals (Cu, Fe and Zn) along western coast of Bali Strait in Banyuwangi, East Java. Bali Strait is one of the many straits in Indonesia with high fisheries activities that could potentially contributed to high heavy metal pollution. There were five sampling areas from the north to south: Pantai Watu Dodol, Pantai Kalipuro, Ketapang Port, Pantai Boom and Muncar as the fish landing area. Heavy metal pollution in these locations comes from many different activities such as tourism, fish capture and fish industry and also domestic activities. Contamination factor (CF), geo-accumulation index (Igeo) and enrichment factor (EF) of each heavy metal were calculated to obtain contamination status of the research area. The concentrations of Fe were observed the highest (1.5-129.9 mg/kg) followed by Zn (13.2-23.5 mg/kg) and Cu (2.2-7.8 mg/kg). The distribution of Cu, Fe and Zn showed variability among the sampling locations in which high concentrations of Cu and Zn were higher in Ketapang Port, whereas high concentration of Fe was high in almost all sampling locations. According to the pollution index, contamination factors of Cu, Fe and Zn were low (CF < 1 and Igeo < 1). However, high index of EF (> 50) showed high influence of the anthropogenic activities to the contribution of the metals to the environment. This could also because of the high background value used in the calculation of the index due to the difficulties in finding background value from the sampling areas.Keywords: heavy metals, pollution index, contamination factor, geo-accumulation index, Bali Strait

AbstractIn most cases, traffic pollution deposition is linear with regularities in its distribution in transect routes (canyon-type effect). The aim of this study is to identify different characteristics of heavy metal deposition on large roundabouts, which are open spaces atypical in terms of the characteristics of the air mass flow along road lanes. The study was conducted on four large roundabouts in Zielona Góra. The content of the selected elements in the tested soils was: Cd 0.54–1.22 mg·kg−1 d.m., Cu 3.60–29.3 mg·kg−1 d.m., Cr 2.17–4.63 mg·kg−1 d.m., Zn 26.6–89.9 mg·kg−1 d.m., Pb 10.9–75.4 mg·kg−1 d.m. The geo-accumulation index was also calculated. The threshold values for communication areas were not exceeded, and the content of the elements was generally comparable between the roundabouts. However, we found some differences within particular roundabouts.

Contamination and pollution of heavy metals in the bottom sediment can pose serious issues to marine organisms and human health. Jakarta Bay which is located adjacent to the capital city of Indonesia is notorious for its pollution problems. The purpose of this research was to assest the contamination levels of heavy metals Hg, Pb, and Cd in sea-bottom sediments based on an index analysis approach (contamination factors, geo accumulation index, pollution load index). Sediment samples were collected from 31 stations in Jakarta Bay. Heavy metal concentration was measured using Atomic Absorption Spectrophotometer (AAS). The results showed that an average mercury (Hg) concentration ranged from 0.150 to 0.530 µg.g-1 with an total average of 0.362 µg.g-1, Lead (Pb) from 14.870 to 35.650 µg.g-1 with an total average of 21.774 µg.g-1, Cadmium (Cd) 0.110-0.280 µg.g-1 with an total average of 0.190 µg.g-1.The average concentration of Hg, Pb, and Cd is still lower than the sediment quality threshold values set by the Office of the State Minister of Environment of Indonesia  2010. The results of the index analysis showed that the average value of contamination factor (CF) are Hg 0.685, Pb 0.558, and Cd 0.380 respectively (low contamination) and geo accumulation index values are Hg 0.237, Pb -1.655, and Cd 0.069 respectively (unpolluted to moderate polluted). Overall, based on the pollution load index value is -0,511 (PLI 1), sediments in these waters are categorized as not yet polluted by Hg, Pb and Cd. This situation  is so necessary to be maintained, that in order for the preservation of marine resources will remain.Keywords: Jakarta Bay, sediment, pollution, heavy metals, assessmentABSTRAKKontaminasi dan pencemaran logam berat pada sedimen dasar dapat menimbulkan masalah yang serius bagi biota laut dan kesehatan manusia.

Agriculture plays an important role in the sustainable development of the country. Use of chemical fertilizers escalate certain components in excess quantity thereby deteriorate the productivity and leads to unpredicted outcome. This study makes an effort to reckon the accumulation of some selected heavy metals [Lead (Pb), Nickel (Ni) and Cadmium(Cd)] and related indices [bio concentration factor(BCF) and translocation factor (TF)] from roots, leaves and fruits of pineapple plantations in Ernakulam district. Contamination factor(CF), enrichment factor(EF) and geo accumulation index (Igeo) disclose the extent of soil contamination in the pineapple cultivated regions of Ernakulam district. Root to shoot TF derived for Pb, Ni, and Cd were 0.25, 0.733 and 0.6731. TF of Pb, Ni and Cd from root to fruit was 0, 0.5 and 0.195 respectively. Values obtained for BCF of Pb, Ni and Cd in root of the pineapple plant were 0.2013,0.5758 and 0.3288. In pineapple leaves BCF showed the values 0.0503, 0.4222 and 0.2214 by Pb, Ni and Cd. Pineapple fruit showed BCF values Zero, 0.2879 and 0.0641 for Pb, Ni and Cd. Enrichment factor for Pb, Ni and Cd in pineapple cultivated areas comes under the value 4.2, 3.7 and 2.8 respectively. Furthermore, the contamination factor of Pb, Ni and Cd was 9.93, 8.26 and 6.23, respectively. The values of geo accumulation index obtained for different heavy metals pass on that the degree of pollution with respect to Pb (6.621) was very strong and extremely contaminated, heavily to extremely contaminated for Ni (5.513) and Cd (4.15).

This study was conducted at Felda Jengka 8, Pahang in Malaysia to find out the contents of heavy metals in palm oil soil and fruit farm soil adjacent to estimate the pollution level. Four types of selected heavy metals namely Cu, Zn, Pb and Ni in different soil sampling point were collected in triplicates and analysed by Inductively Coupled Plasma – Optical Emission Spectrometer (ICP-OES) after wet digestion. Contamination factor (CF) and geo-accumulation index (Igeo) were used to estimate the degree of contamination heavy metal in soil. Heavy metal concentration range were as follow; 0.910 – 2.000 mg/kg for Cu, 0.460 – 2.060 mg/kg for Zn, 0.080 – 0.220 mg/kg for Pb and 0.020 – 0.100 mg/kg for Ni. Cu and Zn concentration was found to be higher than other metal concentrations. The continuous application of chemical fertilizers possibly related to accumulation of heavy metals in soil. Results showed CF values were between moderate to considerable contaminant especially in palm oil soil. While, for Igeo values were indicated uncontaminated to fairly contaminated for the study sites. This recommends the utilization of chemical fertilizer is still in the monitoring. However, more physicochemical analyses are needed for metal analysis and determination of other heavy metal elements such as Cd, As, Se and Cr for further research.

Over the past two decades, the coastal waters of Jinhae Bay have been extensively used by coastal communities and industries for the disposal of domestic and various industrial wastes, therefore increasing the level of pollutants in coastal waters with a subsequent increase in sediments, especially of heavy metals. Specific objectives of this research are to investigate the distribution of heavy metal concentration in biota, to compare the concentrations with those in sediment and water and to relate the bioconcentration to the different heavy metals in biota obtained from several sites. Sixty one percent of heavy metals was found in particulate form during the high runoff season and 32% during the dry season. The behavior of the particulate metals after flowing in to the enclosed coastal sea is an important factor in heavy metal contamination. Copper, lead and chromium contamination of sediment was revealed at several sites. The bioconcentration factors (BCFs) of zinc, cadmium, copper, nickel, chromium and lead by the mussel (Mytilus edulis) were determined as 2,900, 2,814, 807, 423, 228 and 127 in the decreasing order, respectively. The areas located nearest to highly populated city and industries exhibited mussels with the largest accumulation of copper, lead and chromium.

Abstract Surface sediment samples were collected from four areas (the Jingdezhen Industrialized Area (JDZ), Upstream (UP), the Dexing Mining Area (DX), and Downstream (DM)) to investigate the concentration and chemical composition of heavy metals. The sediments were analysed for Cu, Zn, Pb, Cd, Cr, As, and Ni using a sequential extraction scheme according to the improved BCR (European Community Bureau of Reference) method. The obtained results show that the maximum values of Cu (793.52 μg·g−1), Zn (72.09 μg·g−1), Pb (222.19 μg·g−1), and Cd (1.60 μg·g−1) were collected from the DX sampling area, while the JDZ area had the highest concentrations of Cr (97.09 μg·g−1), As (318.05 μg·g−1), and Ni (66.35 μg·g−1). The majority of metal values far exceeded their corresponding background values. The risk analysis of geo-accumulation index (Igeo) indicated that the heavy metals Cu and As were the main pollution factors and each element of the pollution degree followed the order of: Cu > As > Pb > Cd > Cr > Zn. Metal partitioning characteristics were also considered and more than 80% of metals show potential bioavailability and toxic effects.
