Abstract Ten samples were studied from sediments collected the Tigris River in city of Mosul, and gamma ray spectroscopy NaI(TI) was used order to detect calculate content natural radionuclides for all collected. The results analyzed specific activity 226 Ra ranged 6.30±0.319 Bq/kg 13.73±0.411 with mean 9.86±0.385 Bq/kg, 232 Th 13.39±0.626 29.84±0.923 23.05±0.838 while 40 K, it 166.83±6.456 275...

Aromatic hydrocarbons present in Iraqi national surface water were believed to be raised principally from combustion of various petroleum products, industrial processes and transport output their precipitation on water.Polycyclic aromatic (PAHs) included the priority pollutant list due toxic carcinogenic nature. The concern about contamination consequent human exposure have encouraged developme...

In this research, Artificial Neural Networks (ANNs) technique was applied in an attempt to predict the water levels and some of quality parameters at Tigris River Wasit Government for five different sites. These predictions are useful planning, management, evaluation resources area. Spatial data along a river system or area locations catchment usually have missing measurements, hence accurate p...

Abstract Agricultural production of high yielding varieties requires the freely use pesticides and fertilizers, in order to protect crops from pests. Thus, it helps improving quality quantity crops. The aquatic environment is polluted through pesticides, which poses serious health risks ecosystem as well humans. This exposure can directly affect biological regulation, including primary producer...

Abstract In this study, physicochemical and biological examinations of water samples were performed. These analyses included measuring the pH, EC, TDS, TSS, DO, BOD, COD. Turbidity was also measured. Along with primary cations anions, heavy metals such as Fe, Mn, Zn, Cd, Cu, Co, Pb, Ni, Cr, As, Mo, Hg, Al, Li, Be, Se, V, U, Sr are included. The study hydrochemistry incorporates both geochemistr...
