“…Hnatukova et al (2009) also found Pb to be mainly bound to the reducible fraction. Jain et al (2008) also found only 1-3 % of exchangeable Pb in the sediments of the River Narmada, India. The weak association of Pb with the exchangeable fraction is equally observed in the study by Carter et al (2006).…”

Spatial and temporal fractionation of trace metals and major elements in suspended particulate matter in the Seine River was investigated to study the impact of the increasing urbanization in the Greater Paris Region. Suspended sediments in the Seine River were collected between December 2008 to August 2009 upstream and downstream of Paris. They were subjected to total digestion and sequential extraction procedure certified by the Bureau Communautaire de Référence and trace metals along with major elements were analyzed with inductively coupled plasma mass spectroscopy. Metal enrichment factors increased up to eight folds after the Seine River downstream of the Greater Paris Region showing a significant contribution of urbanization. Enrichment of copper, lead and zinc downstream of Paris are followed by the increase of their reducible fraction of at least 10% implicating an increase in metals associated with iron oxides. The exchangeable fraction, which includes the carbonate-associated metals, is only significant for cadmium, nickel and zinc (more than 2 %) while the oxidisable fraction accounts for less than 20 % for the anthropogenic metals downstream except for copper. The metals can be divided to (a) "reducible" group including cadmium, lead, and zinc, associated with more than 60 % of the total Bureau Communautaire de Référence extractable metals to the reducible fraction containing mostly iron oxide phases for the downstream sites. (b) A "distributed" group including chromium, copper, and nickel that are associated to at least 3 different phase-groups: (1) oxides, (2) organic matter and sulphides and (3) mineral phases.

This r esearch was carried out along the banks of the Bogacayi River in the western part of Antalya in Turkey. We investigated the concentration, average distribution, and level of contamination of the sediments by heavy metals for monitoring purposes. In this study, 25 sediment samples from different stations were collected and analyzed along the Bogacayi's banks. Heavy metals detected in order of abundance are Mg> Fe > Al > Ti> MN > Cr > Ni > Ba > V > Zr > Zn > Co > Cu > Pb > As > Mo > W > Cd > Sb > Ag. The average concentration of each heavy metal elements was compared to those of the earth crust, sandstone, ultrabasic rock, especially with the acceptable limit for Turkey, in order to determine their anomalies. The concentration of Cr in sample 24 was 19.85 times and Ni in sample 25 was 19.29-7.71 times higher than the acceptable limit for Turkey. In samples 24 (1.87 times) and 25 (1.85 times), Co was also higher than the acceptable limit for Turkey. As confi rmed by the coeffi cient correlation analysis, the PCA, anthropogenic activities is thought to have possibly contributed most of the Sb, Mo, and Pb, and led to an increase in the quantities of elements such as: Fe, V, Mn, Co, Ni, Mg, Cr, and As. Most of the Al, Ti, Zr, Zn, W, Ba, and Cu, and a majority of the Fe, V, Mn, and Sn, potentially resulted from a natural source. Samples 24 (Zn, Co, Mn, Fe, V, Cr, Mg, and Ba) and 25 (Ni, Co, Fe, and Mg) contain several numbers of heavy metals, each showing high anomalous concentrations, which are related to anthropogenic sources. The ANOVA model summary reveals the high explanatory power of R 2 = 100.00%, indicating that the number of samples used in this study was suffi cient.

“…These five categories have different behavior with respect to remobilization under changing environmental conditions (Jain et al, 2008). The fractions introduced by human's activity include the adsorptive, exchangeable and bound to carbonates/acid soluble phase, which are considered to be weakly bound metals and may equilibrate with the aqueous phase thus becoming more rapidly bioavailable (Gibbs, 1977).…”

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.
