“…It is reported that decomposition of organic matter may lead to decrease the value of pH due to the formation of humic acid (Nobi et al 2010) and consequently increase the metal release. On the other hand, the higher values of pH can reduce the reduction rate of SO 4 2− through the inhibition of activity and growth of sulfate reducing bacteria (SRB) (Hou et al 2013). Our findings also demonstrated that stations with higher concentrations of AVS and SEM had lower pH compare with other stations.…”

Sediment samples from the coastal area of Asaluyeh harbor were collected during autumn and spring 2015. The acidvolatile sulfide (AVS) and simultaneously extracted metals (SEMs) were measured to assess the sediment quality and potential ecological risks. The average concentrations (and relative standard deviation (RSD)) of AVS in the industrial sediments were 12.32 μmol/g (36.91) and 6.34 μmol/g (80.05) in autumn and spring, respectively, while in the urban area, these values were 0.44 μmol/g (123.50) and 0.31 μmol/g (160.0) in autumn and spring, respectively. The average concentrations of SEM (and RSD) in the industrial sediments were 15.02 μmol/g (14.38) and 12.34 μmol/g (20.65) in autumn and spring, respectively, while in the urban area, these values were 1.10 μmol/g (43.03) and 1.06 μmol/g (55.59) in autumn and spring, respectively. Zn was the predominant component (34.25-86.24 %) of SEM, while the corresponding value for Cd, much more toxic ingredient, was less than 1 %. Some of the coastal sediments in the harbor of Asaluyeh (20 and 47 % in autumn and spring, respectively) had expected adverse biological effects based on the suggested criterion by United States Environmental Protection Agency (USEPA), while most stations (80 and 53 % in autumn and spring, respectively) had uncertain adverse effects.

“…Numerous researchers have previously reported on the distribution of heavy metals, assessment of sediment quality, and computation of pollution load on sediments such as Mighan Lake, USA [12]; Nansihu Lake, China [13]; Dojran Lake, Macedonia [14]; Qaroun Lake, Egypt [15]; Mwanza Lake Victoria [16]; and Dalinouer Lake, China [17]. Determining heavy metal contents and their contamination in sediments leads to enhance the understanding of their behavior in the aquatic environment and is extremely significant for assessing pollution sources [18].…”

Heavy metals pollution is a worldwide problem that has grown during the past few decades because of their toxicity, extensive sources, non-biodegradable characteristics, and accumulative behaviors in aquatic environments [1][2][3]. These metals are identified as a significant indicator for degradation of aquatic environments. Enormous quantities of metals are being released into the environment both from anthropogenicrelated processes and natural sources through direct discharge into water or indirectly through stormwater runoff, domestic effluents, fossil fuel combustion, and atmospheric depositions [4]. Heavy metals ultimately Pol. J. Environ. Stud. Vol. 27, No. 2 (2018), 675-688 Original Research Heavy Metals Contamination and Ecological Risk AbstractHeavy metal concentrations were determined using inductively coupled plasma-optical emission spectrometry (ICP-OES) in surface sediments of Namal Lake, Pakistan. The metals content in sediment varied significantly and were in the order of Al>Fe>Mn>V>Zn>Cr>Ni>Cu>As>Co>Pb>Cd. Except for Al, the average concentrations of metals were higher than the average value of the upper continental crust (UCC). The significant positive correlations among heavy metals (p<0.01) suggested that these metals originated from the same sources. The pollution indices indicated severe contamination of sediments with As, Cd, and Ni. The sediment quality guidelines (SQGs) revealed that 19.2% of As, 11.5% of Cr, and 88.5% of Ni from all the sampling sites exceeded the probable effect level (PEL). The computed average risk index (RI) of single elements were in the following order Cd(411.9)>As(69.0)>Ni(15.4)>Cu(10.0)>Cr(4.3)> Pb(3.66)>Zn(1.7). Principle component analysis (PCA) extracted three components explaining (76.136%) of total variance of chemical data and were highly to moderately loaded with Fe, Mn, Co, Cu, Zn, Al, As, Cd, Ni, V, Cr, TOC, pH, CaCO 3 , and Pb in three principal components (PCs). The results obtained from cluster analysis, correlation of heavy metals, and principal component analysis suggested the origin of metals from both anthropogenic and natural sources.

“…Sediments in deeper parts of the lake are characterized by a high content of organic matter and fine mineral fractions which bind metals [11,20]. In Lake Sunia, the lowest levels of trace elements were observed in the shallow zone separating the main body of the lake from the bay, whereas the highest concentrations were reported in the western part of the water body.…”

Abstract:Various elements are accumulated in bottom deposits in concentrations that significantly exceed the levels observed in lake water. Under certain conditions, this can lead to secondary contamination of water, posing a threat to aquatic organisms. The aim of this study was to evaluate the spatial distribution of Pb, Zn and Cr pollutants in the bottom deposits of Lake Sunia. The investigated water body is situated in the Olsztyn Lakeland (western part of the Masurian Lakeland), approximately 30 km north of the city of Olsztyn, in the municipality of Swiatki. The lake has a total area of 111.6 ha and a maximum depth of 8.8 m. The inflow to and the outflow from lake are situated in its south-western and north-western part, respectively. The lake features a bay which is separated from the main water body by a shallow zone. Its catchment area comprises mainly agricultural land. The total area of supply of lake is 450 ha of which inflow catchment area is 70 ha. Most of the catchment area is agricultural land (91%), and in particular arable land, the rest of the area (5%) are the barren, and trees (4%). In the area of the lake is dominated by power-sandy loam soil in the passing sands and clay loam strong little sandy. In terms of particle size are a summary of the soil that is difficult permeable to water and nutrients. Taking into account the valuation of soil classification in the vast quantities of soil are included in the class IVa, IIIa and IIIb. The average content of organic matter in the lake was determined at 24%. Significant accumulation of organic matter results from intense inflow of biogenic substances from farmed areas in the catchment. The average concentrations of trace elements in the analyzed water body were arranged in the following series: Cr < Pb < Zn, and their ratios were determined at 8.1 < 22.9 < 45.2. Higher levels of heavy metals were observed in the profundal zone, whereas lower concentrations of the analyzed elements were noted in littoral zone sediments.Keywords: anthropogenic pressure, bottom deposits, heavy metals All water reservoirs have their bottom, which settle on the organic and inorganic suspensions. They form a bottom deposits characteristic for catchment and morphological feature [1]. The settlement of allochthonous material formed outside the sedimentation zone and autochthonous material created at the place of sedimentation leads to the formation of bottom sediments in water bodies [2]. The content of chemical compounds in sediments is determined by the type of bed rock forming lake catchments as well as land use patterns in the catchment area. Rock strata constitute a point of reference (geochemical background)
