“…In the present study, the significantly positive correlations between the metals such as Fe, Mg, Mn, As, Co, Cr, Cu, Ni, Pb in the sediments indicated possible co-contamination from similar sources of waste input from the surroundings of Lake Chaohu. Alternately, no correlations were noted between Cadmium and other metals, suggesting that Cadmium contamination might be of different origin than other metals or has different sediment deposition characteristics (Olivares-Rieumont et al 2005).…”

“…There were significantly positive correlations between concentrations of nutrient and Fe, Mg, Mn, Cr, Ni and Pb, indicating that the nutrients transported to this lake contributed, to some extent, to the enrichment of metals (Qu et al 2001). The correlation between trace metals concentrations has been used to demonstrate the co-contamination of anthropogenically derived metal enrichment in sediment (Olivares-Rieumont et al 2005). Significant correlations between trace metal concentrations were observed in marine sediments (Presley et al 1992).…”

Metal contents of surface sediments were analyzed temporally and spatially in Lake Chaohu, China. No obvious temporal variations were observed, which probably due to physio-and bio-mixing, e.g. wind and microbes, in this lake. Enrichment factor of some metals were generally greater than 1.0, suggesting significant anthropogenic impact on metal levels. Significantly positive correlations between concentrations of nutrient and metals indicated that the nutrients transported to this lake contributed, to some extent, to the enrichment of metals. The correlation between trace metals concentrations indicated the co-contamination of anthropogenically derived metal enrichment in surface sediment of Lake Chaohu.

“…The exception was the site T1 that showed lower concentrations for this element. The total lead load does not show any significant spatial or temporal variation when as compared to the others tropical rivers (Eysink et al, 1988;Brigante et al, 2003b;Siqueira, 2003;Jain, 2004;Muniz et al, 2004;Olivares-Rieumont et al, 2005), suggesting that this element was preferentially deposited there by natural occurrence. Total lead ranged from ≤ 0.01 (detection limit) to 1.31 µg g -1 .…”

. The concentrations of metals in the industrial and agricultural areas were higher than those in the urban areas. The results demonstrated that terrigenous sediments from the industrial and agricultural areas are dominating factor controlling the spatial variations of heavy metals on the Tapacurá River. Grain size and anthropogenic influences are also major factors modifying the spatial variations of heavy metals. Pb and Cd had higher enrichment factors. The maximum potential contamination indices for the basin were 218 to Pb and 660 to Cd. The correlation analysis showed that the Fe and OM varied independently from one another, implies that the concentration of metals in sediments can not be interpreted simply by a change in grain size. The first step to apply a remedial measure is the inspection of the agricultural areas and the use controlled of fertilizers and herbicides. Information of this nature on heavy metals can provide valuable contribution to the program of sanitation at the Companhia Pernambucana de Meio Ambiente -CPRH.

“…Contaminated sediments of heavy metals are currently a widespread problem with the potential to threaten water quality and aquatic ecosystems [1,2]. In most cases, heavy metals entering into rivers can be stored in the river sediments in various forms.…”

Remobilization of heavy metals during the resuspension of Liangshui River sediments using an annular flume

The release and transport of heavy metals (Ni, Cr, Cu and Pb) from Liangshui River sediments into the overlying water column during the resuspension event were determined using an annular flume with a velocity ranging from 0.15 to 0.35 m/s. It is shown that the suspended particulate matters (SPM) increased as much as nearly 25 times from 165 to 4220 mg/L as the velocity increased. Heavy metals showed an increase in dissolved phase as the velocity increased due to their desorption from the SPM. Acid-soluble heavy metals increased as the velocity increased, indicating that part of the heavy metals transformed from stable phase to labile phase during resuspension. Heavy metal concentrations in the SPM on volume normalization increased by approximately 2-6 times. However, on the mass weighted basis they decreased, approaching the bulk-sediment contents at high velocity, due to the "particle concentration effect". The distribution coefficients (K D ) of heavy metals were higher at slower velocity during the sediment resuspension, which could be attributed to the decrease of fine particles (silt/clay fraction) during resuspension.heavy metals, sediment resuspension, suspended particulate matters, acid-soluble heavy metals, annular flume Citation:Huang J Z, Ge X P, Yang X F, et al.
