Due to the great possibility of water contamination of many rivers by human activities in Iran, the study of water quality is crucial for water resource protection and human health. High level of phosphorous is the main reason for eutrophication of freshwater systems. The main aim of this study was to investigate the concentration of phosphorus in the rivers feeding into Taham dam in Zanjan, us...
Background; Contamination of water and soil through non-point sources such as road runoff causes environmental concern. The aim of this study is to determine the effect of Zanjan – Chavarzagh road on the total organic carbon (TOC) content of sediments in tributaries and the river that lead to Taham Lake. Methods; In tributaries and the river 69 soil and sediment samples were taken and the Tota...
Dam construction is one of the challenges among large-scale projects of a country. Among different types of dams, due to special features, earth dams are the most kind of dams that were constructed in Iran in the past three decades. Features such as efficiency and stability of earth dams have an important effect on their operation and prevent them to be damaged. Taham dam is clay core dam which...
Background and purpose: Presence of heavy metals in the environment could constitute a hazard to food security and public health. These can be accumulated in aquatic animals such as fish, therefore, this study was conducted to investigate the As, Hg, Zn, Pb, Cd and Cu concentrations in muscle tissue of Cyprinus carpio in Taham Dam Lake in 2013. Material and Methods: Twenty five fish samples we...
