Abstract

This study investigate the effects of the city on the water quality of Tigris River, Water samples were collected from upstream, midstream and downstream sections of the river within Baghdad city. This study included the analyzed of Physico-chemical parameters and compared them with CCME Standard Values for protection of aquatic life and application of CCME mathematical model that facilities the expression of the result and gives a clear picture for the river status, eleven parameter were used to compute the CCMEWQI which are: pH, Water Temperature, Dissolved Oxygen, Total Dissolved Solids (TDS), Chloride (Cl), Ammonia (NH4), Nitrate (NO3), Nitrite (NO2), phosphate (PO4) Turbidity, Lead (Pb) and Copper (Cu). The result show that all stations in both seasons (winter &summer) have poor valuation, which indicate that’s Tigris River in Baghdad city are heavily polluted for the aquatic life.

Abstract

Atmospheric wet depositions have distinct characteristics in terms of associated pollutant types and influential parameters. This paper discusses the concentration of some heavy metals (Pb, Cd and Ni) in selected urban areas for wet depositions. Wet deposition samples, which are represented as rainwater collected from October 2013 through April 2014. The results indicated that industrial area exhibits the higher mean concentrations of Cd, Ni and Pb. Overall results imply that important anthropogenic sources are likely the most sources of heavy metals in this region.

Abstract

The proposed water and sediment quality of Shatt Al-Basrah was assessed by (1) using Geographic Information Systems (GIS) using Inverse Distance Weighting (IDW) method for calculating nutrient concentrations of water and sediment samples, (2) evaluating Partition Coefficient (Kd) and cluster analysis for water and sediment samples. The GIS facilitates the explanations of the spatial relationships among key environmental processes. It employs spatial distribution modeling to analyze the nutrient concentrations of Nitrite as N (NO2-N), Nitrate as N (NO3-N), Ammonia as N (NH3-N), Ammonium (NH4), and Sulfate (SO4) in the water and sediment. This paper shows that the results of Partition Coefficient (Kd) is always less than 3 for all sites illustrating that the pollutants are present in liquid phase preferentially which have high solubility and are less sediment-associated.
