“…En sistemas hí-dricos, los sedimentos son grandes reservorios de todos los contaminantes incluyendo los metales pesados [3][4][5]. Estos elementos contribuyen significativamente a la contaminación del agua, aire y suelo [2,6] debido a su toxicidad, persistencia, bioacumulación, biomagnificación, ciclos biogeoquímicos y el riesgo ecológico que representan [1,5,[7][8][9][10].…”

En las muestras analizadas, el 43 % del Na, el 93 % del Fe, el 70 % de Mg, el 62 % de Mn y el 94 % de K están asociados con la fracción fina de los sedimentos. Las concentraciones de Mg, Na y Mn están influenciadas por las actividades petroleras mientras que el contenido de Fe, K y Al está relacionado con el origen natural de los sedimentos. Sin embargo, aguas abajo, hasta la frontera con Perú, no se observa un incremento significativo en las concentraciones de elementos mayores en relación a los puntos de control, aguas arriba de la ZIL, Zona de Influencia Local de las actividades petroleras. Palabras Analisis of major cations in bottom sediments from oil impacted Rivers, in the Ecuadorian Amazon AbstractHeavy metal pollution is one of the biggest problems of great concern at the global, regional and local levels due to mining and oil activities, because those elements constitute a threat to aquatic biota and human health. The major elements and heavy metals tend to accumulate in sediments, which act as secondary sources of contamination, and this process is closely related to the redox conditions, the particle size distribution of the sediments and the amount of sedimentary organic matter. Therefore, the aim of this work conducted in the frame of the MONOIL Research Program between France and Ecuador, is to determine the concentration of major elements (K, Mg, Na, Fe, Mn and Al) in the fine fraction of sediments, particles <4 µm, collected in the basins of the Aguarico, Napo and Esmeraldas Rivers, which are areas affected by the oil industry in Ecuador. Concentrations of major elements in the fine fraction are then compared to concentrations in the bulk, which was determined in the same sampling points in a previous work. Environmental parameters in surface waters such as temperature, dissolved oxygen (DO), pH, conductivity and oxide reduction potential (ORP) were determined in situ in each sampling point. The isolation of the fine fraction was carried out based on Stokes' law after a homogenization, quartering and dissolution of the sediment in distilled water. Mineralization in sediments was performed by a triacid attack with HCl, HNO3 and HF. The major elements were determined by atomic absorption spectrophotometry (AAS). The ranges of major elements in the fine fraction of sediments were: Fe: 18-49, Al: 26-59, K: 3-15, Mg: 3-13, Na: 1-11 and Mn: 0.38-0.89 mg g −1 ; while concentrations in the bulk sediment concentrations were: Fe: 25-49, Al: 45-82, K: 5-20, Mg: 4-16, Na: 3-24 and Mn: 0.43-1.28 mg g −1 . In the sediment samples of the Northern Ecuadorian Amazon rivers, 43 % Na, 93 % Fe, 70 % Mg, 62 % Mn and 94 % K are associated with the fine fraction. The concentrations of Mg, Na and Mn in bottom sediments are influenced by oil activities, while Fe, K and Al concentrations depend on the natural origin of sediments. However, downstream up to the border with Peru, no significant increase in the...

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.

Background and Purpose: The heavy metal pollution and its fractionations in the surface sediments of Darreh-Morad Beyg River, Hamedan City were monitored for Cd, Cr, Cu, Fe, Ni, Pb, and Zn in 2014. Materials and Methods: Totally 30 surface sediment samples were taken from 10 stations with three replicates. The samples subjected to bulk digestion and chemical partitioning. The concentrations of heavy metals in sediment were determined by ICP-OES. I-geo, EF, CF, and PLI were also used to assess the sediment contamination. Results:The results of the present study showed that the proportions of residual fraction for Cu, Ni, Pb, Cd and especially Cr (93.61%) were relatively high, which implied their lower pollution risks due to low mobility characterization, while Zn was mainly associated with the anthropogenic portion of the existing pollution which meant an increase in mobility for this element. Also, on the basis of the mean, the I-geo values of metals were found in the following order: Cr>Cu>Zn>Ni>Pb>Fe>Cd. At the same time, the average EF of metals in the sediment samples was in the order of Cr>Cu>Zn>Ni>Pb>Fe>Cd. According to the calculated PLI, the pollution class of heavy metals in sediments from the Darreh-Morad Beyg River was between 1 and 2, indicating a moderately polluted degree. Conclusion: Regarding the high Zn concentrations in sediments, it is likely that this element is a major hazard for the aquatic environment since it is mainly found in the anthropogenic portion. Also, Cu, Ni, Pb, Cd, and Cr are present in the greatest percentages in the residual fraction, which implies that these metals are strongly linked to the sediments.
