The vanadium geochemistry was estimated in the topsoil of Kirkuk, northern Iraq, and its potential sources are forecasted by using multivariate statistical analysis as useful tools in this field, in addition to assessing soil pollution with vanadium by using individual indices such as enrichment factor, geo-accumulation index (Igeo) and contamination factor (CF). Eighteen topsoil samples were collected with a depth ranges 0–20cm, and analyzed by using the inductively coupled plasma-mass spectrometer technique (ICP-MS). The results showed that the concentration of vanadium ranged from 37-51 mg/kg, with an average of 46 mg/kg, relatively it was high concentrations in the agricultural and residential areas compared to the industrial areas. Statistical analysis indicated the contribution of oil combustion and the use of phosphate fertilizers in increasing vanadium concentrations in topsoil. Pollution indices of enrichment factor were in the minimal enrichment category for all samples, geo accumulation index was non-contamination categories for all samples, while Contamination factor was low for all samples.

Heavy metal pollution of water, sediments and Algae in the upper region of River Benue at Jimeta-Yola, Adamawa state, Nigeria was assessed. The concentrations of the heavy metals (Pb, Hg, Ni, Cu, Cr, Zn, Mn, Fe) in the samples were analyzed using Atomic Adsorption Spectrometer. Pollution parameters such as enrichment factor, contamination factor, pollution load index and geo-accumulation index were evaluated. The result of heavy metal analysis showed that, the concentration (ppm) of the metals in water samples ranged as follows: Pb(0.25-0.50), Hg(0.00-2.00), Ni(0.10-0.31), Cu(0.03-0.13), Cr(0.00-1.33), Zn(0.01-0.04), Mn(0.03-0.06) and Fe(105.15-118.75) respectively. This result when compared with the EPA maximum permissible limits for drinking water showed that, all the metals except Cu and Zn had values above the permissible limits. The evaluation of enrichment factor revealed that, Hg showed extremely high enrichment while Pb showed significant enrichment for Algae, water and sediment samples. The contamination factor showed low contamination for all metals except Hg which showed considerable contamination for sediments, water and Algae samples. The pollution load index for sediments, water and Algae indicated no pollution. The geo-accumulation index of the metals in sediments, water and Algae indicates no or minimal pollution. The samples were enriched with Hg and Pb. These metals are capable of causing various types of cancer, brain and kidney damage among other ailments.

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).

The sediment pollution caused by different metals has attracted a great deal of attention because of the toxicity, persistence, and bio-accumulation. This study focuses on heavy metals in the hyporheic sediment of the Weihe River, China. Contamination levels of metals were examined by using “geo-accumulation index, enrichment factor, and contamination factor” while ecological risk of metals were determined by “potential ecological risk and risk index”. The pollutant accumulation of metals ranked as follows: “manganese (Mn)   >   chromium (Cr)   >   zinc (Zn)   > copper (Cu)   >   nickel (Ni)   >   arsenic (As)   >   lead (Pb)”. The geo-accumulation index identified arsenic as class 1 (uncontaminated to moderate contamination), whereas Cu, Cr, Ni, Zn, Pb, and Mn were classified as class 0 (uncontaminated). According to the enrichment factor, arsenic originated through anthropogenic activities and Cr, Ni, Cu, Zn, and Pb were mainly controlled by natural sources. The contamination factor elucidated that sediments were moderately polluted by (As, Cr, Cu, Zn, Mn, and Pb), whereas Ni slightly contaminated the sediments of the Weihe River. All metals posed a low ecological risk in the study area. The risk index revealed that contribution of arsenic (53.43 %) was higher than half of the total risk.

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

Abstract The present study is an attempt to assess the pollution intensity and corresponding ecological risk of phosphorus and metals including Cd, Cr, Cu, Zn, Pb and Fe using various indices like geo-accumulation index, enrichment factor, pollution and ecological risk index. In all, 20 surface soil samples were collected from the Ait Ammar iron mine of Oued Zem city, province of Khouribga, in central Morocco. The concentrations of heavy metals in soil samples were used to assess their potential ecological risks. According to the results of potential ecological risk index (RI), pollution index (PI), geo-accumulation index (Igeo), enrichment factor (EF), potential contamination index (Cp), contaminant factor (Cf) and degree of contamination (Cd), based on the averages, considerable pollution of metals in soils of study area was observed. The consequence of the correlation matrix and principal component analysis (PCA) indicated that Fe, Cu, Zn, Cr and P mainly originated from natural sources and Cd and Pb are mostly derived from anthropogenic sources. The results showed that these metals in soil were ranked by severity of ecological risk as Pb > Cd > Cu > Cr > Zn, based on their single-element indexes. In view of the potential ecological risk (RI), soils from all soil samples showed a potential ecological risk. These results will provide basic information for the improvement of soil environment management and heavy metal pollution prevention in Ait Ammar.

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.
