“…This study provides valuable information on the potential mobility and bioavailability of heavy metals in river sediments. As it is indicated in lots of studies, toxicities and bioavailabilities depend on heavy metal species, e.g., free ion and labile complexes are more toxic and bioavailable to aqueous organisms and plants (Ibrahim Korfali and Davies 2004;Murakami et al 2009;Degryse et al 2006;Rijstenbil and Poortvliet 1992). Accordingly, it may be concluded from the chemical partitioning data that there are significant differences in the distribution of the metals studied.…”

The Haraz River is one of the most significant rivers in the southern Caspian Sea basin. Towards the estuary, the river receives discharges of industrial, agricultural, and urban wastes. In the present investigation, bulk concentrations of Cu, Zn, As, Cd, Pb, Fe, Ni, Cr, Co, and Sr in Haraz River (Iran) bed sediments were measured from several sample locations. In addition, association of studied metals with various sedimentary phases was assessed to determine the proportions of metals in different forms. The intensity of sediment contamination was evaluated using an enrichment factor (EF), geo-accumulation index (I(geo)), and a newly developed pollution index (I(poll)). Both EF and I(geo) formulae compare present concentrations of metals to their background levels in crust and shale, respectively. In a specific area with its own geological background like Haraz River water basin where naturally high concentrations of metals may be found, such a comparison may lead to biased conclusions regarding levels of anthropogenic contamination. Accordingly, chemical partitioning results are substituted for the mean crust and shale levels in the new index (I(poll)). The Pearson correlation coefficient between the anthropogenic portion of metallic pollution in Haraz river-bed sediments with I(poll) showed much more value in comparison with those of geochemical accumulation index and enrichment factor. The order of metals introduced by anthropogenic activities are as follows: Sr > Pb > Co > Cd > Zn > Cu > Ni > As > Cr > Fe. The results showed relatively higher concentrations of Cd, As, Sr, and Pb in comparison with those of shale. However, based on the chemical partitioning of metals, it is found that Sr, Pb, Co, and Cd are the most mobile metals. In spite of the high As concentrations in sediments, it is not likely that this element is a major hazard for the aquatic environment since it is found mainly in the residual fraction. Also, Fe, Cr, and Ni are present in the greatest percentages in the residual fraction, which implies that these metals are strongly linked to the sediments.

“…Series of physical, chemical and biological reactions, such as sorption-desorption [4], ion exchanges, complexation [5], oxidation-reduction [6], precipitation [7], and bioaccumulation [8], will occur, once heavy metal enters water bodies. The sorption of heavy metals onto suspended and riverbed sediments can reduce their concentration in aquatic systems, whereas desorption can lead to secondary heavy metal pollution [9,10]. Thus, sorption and desorption of heavy metals on sediments play extremely important roles in influencing water quality to a considerable extent [11].…”

Sorption is a crucial process that influences immobilization and migration of heavy metals in an aqueous environment. Sediments represent one of the ultimate sinks for heavy metals discharged into water body. Moreover, the particle size of sediments plays an extremely important role in the immobilization of heavy metals. In this study, the sorption and desorption of cadmium (Cd) and copper (Cu) onto sediments with different particle sizes were investigated to predict the rate and capacity of sorption, to understand their environmental behaviors in an aqueous environment. Batch sorption and kinetic experiments were conducted to obtain the retained amount and rate of Cd and Cu in a binary system. Experimental data were simulated using sorption models to ascertain the sorption capacity and the kinetic rate. Results of European Communities Bureau of Reference (BCR) sequential extraction showed the highest concentration of Cd (0.344 mg kg −1 ), and its distribution varied with sediment particle size and site. Furthermore, most of Cu (approximately 57% to 84%) existed as a residual fraction. The sorption of Cu onto six sediments followed a pseudo-first order reaction, whereas that of Cd followed a pseudo-second order reaction. Additionally, the competitive Langmuir model fitted the batch sorption experimental data extremely well. The highest sorption capacities of Cd and Cu reach 0.641 mmol kg −1 and 62.3 mmol kg −1 , respectively, on the smallest submerged sediment particles. The amounts of Cu and Cd desorbed (mmol kg −1 ) increased linearly with the initial concentration increasing. Thus, sediment texture is an important factor that influences the sorption of heavy metal onto sediments.

“…However, these variations are found to be influenced by particle characteristics as the pollutants are generally strongly bound to particles (Badin et al, 2008;Charlesworth and Lees, 1999;Sansalone and Buchberger, 1997b;Vaze and Chiew, 2004;Vaze and Chiew, 2002;Zafra et al, 2011). Several studies have reported the fact that pollutant adsorption by particles depends on their physical and chemical characteristics such as particle size, surface area, surface charge distribution, surface coatings and organic matter content (Gunawardana et al, 2013;Gunawardana, 2011;Khanal et al, 2014;Murakami et al, 2009;Sposito, 2008;Zhang et al, 2016). Therefore, the influence of such characteristics is inevitable in the context of process variability.…”

“…Consequently, this signifies the influence of particle size on the variations in load and composition of associated pollutants over time in response to the different behaviour of particles, which in effect generates process variability. Additionally, several other particle characteristics such as, surface coating, organic matter content, pH and dissolved organic carbon (DOC) are found to either enhance or limit the adsorption capacity of particles, thereby, influencing the amount of adsorbed pollutants (Bradl, 2004;Murakami et al, 2008Murakami et al, , 2009Zhang and Zhao, 1997). Surface coatings generally exist in the form of hydrous metal oxides and organic matter, producing a variable charge on the particle surface (Gunawardana, 2011).…”
