The research estimation of heavy metals in the water, `plants and soils adjacent to agriculturalareas of the waters of the Tigris river in Al- Grea't-Baghdad-Iraq region. In order to recognize thequality of these pollutants in the water we conducted a series of physical measurements and chemicalanalysis included physical measurements - measurement of temperature, conductivity electricalquality and turbidity The chemical analyzes encompassing measure pH and brackish and basalgroup dissolved solids (TDS) and total suspended solids (TSS) chemical oxygen demand (COD)and estimate the amount of grease and oil gravimetric methods. Chemical analysis also includedthe estimate of negative ions using Visible Spectroscopy region - UV. Such as sulfates (SO4-2) andphosphate (PO4-3) and nitrate (NO3-) and to identify the concentration of cationic main water ionswere estimated ions K+1, Ca+2 , Mg+2. Due to the importance of assessing the trace heavy metals inwater and that their direct impact on human health has been measured elements mediated by flameatomic absorption spectroscopy technique. Previous analyzes of the use of chemical analyzes classicvaried as in the measurement of ions (Cl-, HCO3- ,Ca+2 ,Mg+2) or use a spectrometer visible area - UVtechniques. The current study also was conducted to demonstrate the possibility of using some of theaquatic life as evidence of contamination with heavy metals in the Tigris River in Al- Grea't area.The study included measurement of the concentration and distribution of some heavy metals and iscadmium, cobalt, lead, copper, iron, zinc, metals) sodium potassium and magnesium in the tissues oftwo types of aquatic plants (lentil water and flower Nile-Helianthus annuus L) as well as the evaluationof some physical and chemical properties of the three stations of the soils in Al- Grea't area
