“…The concentrations of heavy metals in surface sediment can be affected by geochemical processes and human activities. Heavy metals discharged into a lake can strongly accumulate in sediment, biomagnify through foodchains, and affect human health (Rashed 2001;Yuan et al 2004;Chen et al 2013;Li et al 2014;Gupta et al 2015). Heavy metals are not degraded in the environment, so they can often cause toxic effects far from their sources (Guagliardi et al 2013;Gao et al 2014).…”

The aquatic environment is affected by heavy metal pollution. This study was conducted to test the hypothesis that environmental factors and anthropogenic activities influence the distributions and the risks posed by heavy metals in surface sediments in shallow lakes in eastern China, which is an area affected by rapid urbanization, industrialization, and population growth. Total Cd, Cr, Cu, Ni, Pb, Se, and Zn concentrations in sediment samples were determined using inductively coupled plasma optical emission spectrometry. The I geo showed that sediments in the lakes were moderately polluted with Cr,Cu,Pb,and Zn,and the EF method showed that Cd and Se were significantly enriched in lakes. The heavy metals were found to pose moderate risks in most of the lakes, except for Gaoyou Lake, Honghu Lake, Poyang Lake, and Weishan Lake. The RI method indicated that very high risks were posed in Dongting Lake and Poyang Lake. Cd was found to pose much higher levels of risk than the other metals. Significant correlations were found between the heavy metal concentrations and the total carbon, nitrogen, phosphorus, and sulfur concentrations. The gross domestic product represented anthropogenic activities well. The gross domestic product of an area and the gross domestic products of primary and secondary industries in an area all had significant relationships with the concentrations of Cu and Pb, indicating that anthropogenic activities have different impacts on pollution with different heavy metals. The gross domestic product index was found to be a driving force behind the pollution of lakes with heavy metals.

“…Considerable differences exist between the chemical composition of the pore water and the sediment. Yuan, et al, 2004 studied the speciation of heavy metals in marine sediments from the East China Sea by ICP-MS with sequential extraction. They found that more than 90% of the total concentration of V, Cr, Mo and Sn existed in the residual fraction.…”

Sediment serves as a reservoir for heavy metals and therefore, deserves special consideration in the planning and design of aquatic pollution research studies. An undisturbed sediment column contains a historical record of geo chemical characteristi cs. It will allow an investigator to evaluate geo chemical changes over time, and possibly, to establish baseline levels against which current conditions can be compared and contrasted. Metals may be mobilized as a result of natural processes (e.g., weathering and erosion of geo chemical formations) as well as by anthropogenic activity. In the mobilization process, trace elements may be absorbed by days, can complex with organic compounds or may co-precipitate with oxide and hydroxides. Indeed sediment shows a high capacity to accumulate and integrate on time.

“…2 and 3). The probable explanation for association of Pb in the residual fraction may be due to the incorporation of Pb in alumino-silicate minerals (Yuan et al, 2004) therefore, it is unlikely to be released to pore waters through dissociation. So that incorporation into the crystalline structures of minerals particles could be regarded as the major transport mechanism for this metal.…”

Problem statement: Urban river sediment pollution due to Zn and Pb is a serious problem in all over the world. The source and level of Zn and Pb pollution in sediments of Nomi River of Ota Ward, one of the most industrialized areas in Tokyo, Japan is still lacking. Approach: The present study focused on Rare Earth Elements (REEs) and geochemical partitioning of Zn and Pb in sediments of 19 sampling sites of Nomi River in order to examine the mobility pattern. The amounts of Zn and Pb in the liquid extract of 5 (five) geochemical phases were measured by using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and the concentrations of REEs in sediments were determined by using X-ray Fluorescence Spectroscopy (XRF). Results: Speciation data indicate dominant labile fraction of Zn, which is related to the presence of several anthropogenic influence of the investigated area. Enrichment Factor (EFc) and Index of geoaccumulation (I geo ) value were compatible with the result, which confirm pollution status of Zn. Environmental risk of Zn and Pb were also evaluated using the Risk Assessment Code (RAC) and sequential extraction results and found Zn poses high to very high risk (34-59), whereas Pb poses low to medium environmental risk (0-19). Conclusion: The mean values of REEs and other minor elements were lower or very close to average shale and Japanese river sediment value but Sr, Sn, Zr and Sb contents were little bit higher than average Japanese river sediment values. Anthropogenic activities, prevalent in the study area play a key role in the accumulation of Zn and Pb in aquatic system. Early warning on the sediment pollution to respective authorities help in preserving the aquatic system from further degradation of the river.
