Assessment of Heavy Metal Contamination in Surface Sediment of the Darreh-Morad Beyg River
Background and Purpose: The heavy metal pollution and its fractionations in the surface sediments of Darreh-Morad Beyg River, Hamedan City were monitored for Cd, Cr, Cu, Fe, Ni, Pb, and Zn in 2014. Materials and Methods: Totally 30 surface sediment samples were taken from 10 stations with three replicates. The samples subjected to bulk digestion and chemical partitioning. The concentr...

متن کاملAdsorption of Heavy Metal onto the Materials Prepared by Biomass
The amount of heavy metal ions released into the environment has been increased due to industrial activities and technological development. Furthermore, indiscriminate disposal has caused worldwide concern for many years because of the toxicity, accumulation in the food chain, persistence in nature, and concentration by organisms [1–3]. Heavy metals are not biodegradable and tend to accumulate ...
متن کاملSurface Complexation Model for the Heavy Metal Adsorption on Natural Sediment
Surface complexation models (SCMs) have been successfully used to describe metal ion adsorption on pure mineral materials. However, such models have rarely been applied to model adsorption on natural materials. In this study, the surface complexation model approach was used to describe the surface properties and adsorption behavior of natural aquatic sediment. Three typical versions of the surf...
متن کاملSurface sediment properties and heavy metal pollution assessment in the Pearl River Estuary, China
Grain size and concentrations of heavy metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), and zinc (Zn)) of 148 surface sediments and activities of 210Pb and heavy metal concetrantions of one sediment core from the Pearl River Estuary were analyzed. The surface sediments were dominated by silt and sandy silt. Sediment type controlled the spatial distributio...
