Seasonal variation in physico-chemical properties and zooplankton biomass in Greater Zab River -Iraq
صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...
متن کاملParasitic fauna of spiny eel Mastacembelus mastacembelus from Greater Zab river in Iraq
A total of 128 spiny eels Mastacembelus mastacembelus (Mastacembelidae) were collected from theGreater Zab river at Iski Kalak town, west of Erbil city, Kurdistan region, Iraq, from July 2007 to the end ofJune 2008. The fish were examined for ecto and endo parasites. The study revealed the existence of 16species of parasites (with a total prevalence of 89.06%) including: two species of protozoa...
متن کاملDesigning a Dynamic Data-Driven Application System for Estimating Real-Time Load of Dissolved Organic Carbon in a River
Understanding the dynamics of naturally occurring dissolved organic carbon (DOC) in a river is central to estimating surface water quality, aquatic carbon cycling, and global climate change. Currently, determination of DOC in surface water is primarily DDDAS developed in this study for estimating the real-time variation of DOC in a river ecosystem.
متن کاملInfluence of dissolved organic matter on dissolved vanadium speciation in the Churchill River estuary (Manitoba, Canada).
Diffusive gradients in thin films (DGT) devices were used to investigate the temporal and spatial changes in vanadium (V) speciation in the Churchill estuary system (Manitoba). Thirty-six DGT sets and 95 discrete water samples were collected at 8 river and 3 estuary sites during spring freshet and summer base flow. Dissolved V concentration in the Churchill River at summer base flow was approxi...
متن کاملThe Effect of Pollutants Dissolved Oxygen and Temperature Change (Case Study:Ghezel-Ozen River)
Rivers can absorb certain amounts of contamination relying on different factors such as: river discharge, the primary conditions of the river, the river depth, discharge and the river viscosity of the offloaded wastes in the river. From parameters of water quality point of view, it is recom-mended to determine some parts of the river which are lower than the standard level in order to find out ...
