“…Kalbitz and Wennrich (1998) and Gonzalez et al (2006) reported that organic matter could act as a major sink for trace elements due to its strong ability to form complexes with metallic contaminants. The role of organic matter in accumulating trace metals to sediments was also emphasized by Wakida et al (2008).

Surface sediment samples were collected from Ziqlab dam in northwestern Jordan to investigate the spatial distribution of selected trace metals and assess their pollution levels. The results showed that the concentrations of Pb, Cd, and Zn exceeded the environmental background values. Cd, Ni, and Cr contents were higher than the threshold effect level (TEL) in 63, 83, and 60 % of the reservoir sediments, respectively; whereas Pb, Zn, and Cu were less than the TEL limit. The concentrations of trace metals in reservoir sediment varied spatially, but their variations showed similar trends. Elevated levels of metals observed in the western part (adjacent to the dam wall) were coincided with higher contents of clay-silt fraction and total organic matters. Multivariate analysis indicated that Pb, Co, and Mn may be related to the lithologic component and/or the application of agrochemicals in the upstream agricultural farms. However, Cd and Zn concentrations were probably elevated due to inputs from agricultural sources, including fertilizers. Evaluation of contamination levels by the Sediment Quality Guidelines of the US-EPA, revealed that sediments were non-polluted to moderately polluted with Pb, Cu, Zn, and Cr, but non-polluted to moderately to heavily polluted with Ni and non-polluted with Mn. The geoaccumulation index showed that Ziqlab sediments were unpolluted with Pb, Cu, Zn, Ni, Cr, Co, and Mn, but unpolluted to moderately polluted with Cd. The high enrichment values for Cd and Pb (>2) indicate their anthropogenic sources, whereas the remaining elements were of natural origins consistent with their low enrichment levels.

“…The concentration data of metals in the Yellow sediments were subjected to the simple linear regression analysis to examine the possible correlation among different metals [9,12,24]. The significant positive correlation among contents of Cu, Fe and Zn concentrations was shown (Table 3).…”

“…Natural sources mainly included weathering of soil and rock, erosion, forest fires, and volcanic eruptions, whereas urban and industrial discharge, mining and refining, and agricultural drainage caused by anthropogenic activities also discharged into the rivers [19][20][21][22][23][24]. Knowledge of the distribution and concentrations of the heavy metals in the sediments could help detect the source of pollution in the aquatic systems.…”

Sediments act as both carriers and sinks for contaminants in aquatic environments [1], which causes pollutants to play an important role and provides a reasonable history of pollution in the river [2]. Metals are regarded as serious pollutants of aquatic ecosystems because of their environmental persistence, toxicity, and ability to be incorporated into food chains [3][4][5]. When the environmental conditions of the water lying over the sediments changes, heavy metals in the sediments could be released into the water, thereby deteriorating its quality [6,7]. Since they can pose potential threats to ecosystems and human health, the distribution and pollution levels of heavy metals in sediments has been extensively studied [7][8][9][10][11][12][13][14][15][16][17][18].Heavy metals have long been continuously introduced into river, estuarine, and coastal sediments. Heavy metals were added to an aquatic system by natural or anthroPol. J. Environ. Stud. Vol. 24, No. 3 (2015), [1041][1042][1043][1044][1045][1046][1047][1048] AbstractThe concentrations of heavy metals in 21 samples collected from surface sediments from the Qinghai section of the Yellow were investigated in order to evaluate their distribution and pollution levels. The total concentrations showed wide variations with Cu 11.86~57.02 mg/kg, Fe 17236.67~41340.00 mg/kg, Mn 431.93~877.27 mg/kg, Ni 14.58~86.11 mg/kg, Zn 67.18~149.00 mg/kg, Cr 87.84~169.70 mg/kg, Pb 1.21~20.69 mg/kg, and Cd 0.27~1.43 mg/kg. The mean values of the heavy metal contents were arranged in the following decreasing order: Fe>Mn>Cr>Zn>Ni>Cu>Pb>Cd. The correlation between Cu, Fe, and Zn concentrations was significantly positive. These heavy metals had common sources, mutual dependence, and identical behavior during transport. However, there was no significant correlation among some of these metals, indicating different anthropogenic and natural sources. PCA extracted three components with eigenvalues explaining 76.259% of the total variance. Fe, Mn, and Zn had a common natural origin controlled by the first component. Cu, Ni, and Cd could originate anthropogenic sources controlled by the second component. The higher values of geo-accumulation index, enrichment factor, and pollution load index of Cr in the Qinghai section were attributed principally to anthropogenic activities such as industrial effluents, vehicular emissions, and terrigenous influx from the river. Zn appeared to pose no risk at all of the sites of the system. In total, the pollution class from the Qinghai section of the river is 0-1, belonging to the unpolluted to moderately polluted degree.

ABSTRAKPulau Bangka kaya akan sumber daya mineral khususnya timah. Kegiatan penambangan timah di pulau ini menghasilkan limbah berupa tailing, dan limbah bahan bakar minyak yang berasal dari kapal pengeruk pasir timah. Limbah tersebut mengandung logam berat yang bersifat toksis terhadap biota laut. Pengukuran kadar logam berat Pb, Cd, Cu, Zn dan Ni dalam sedimen di perairan ini telah dilakukan pada bulan September 2010. Tujuan penelitian ini adalah untuk menprediksi tingkat pencemaran logam berat Pb, Cd, Cu, Zn, dan Ni dalam sedimen dengan menggunakan indeks beban pencemaran (pollution load index, PLI) dan indeks geoakumulasi (geoaccumulation index, I-geo). Contoh sedimen diambil dari 20 stasiun dengan menggunakan Gravity Core. Kadar logam berat dalam semua contoh ditentukan dengan menggunakan Spektrofotometer Serapan Atom (AAS) dengan nyala campuran udara dan asetilen. Hasilnya menunjukkan terdapat perbedaan prediksi tingkat pencemaran sedimen antara Indeks Beban Pencemaran dengan Indeks Geoakumulasi. Berdasarkan nilai indeks beban pencemaran, sedimen di perairan Bangka ini belum tercemar oleh logam Pb, Cd, Cu, Zn, dan Ni (PLI<1). Berdasarkan indeks geoakumulasi, sedimen juga tidak tercemar oleh Pb, Cu, Zn, dan Ni (Igeo<0), tetapi untuk Cd termasuk dalam 3 kategori tingkat pencemaran yakni tidak tercemar ((I_geo<0), tercemar ringan (0
