| FIA is a very successful method in simplifying chemical assays. The main reasons for the success are the following advantage of FIA over conventional manual techniques: High sampling rate, smaller sample and reagent consumption and waste generation, simplicity and low cost instrumentation, Availablability of instrumentation in all laboratories, increased precision compared to batch methodologies and Automation in sample preparation and detection. A Study was conducted monthly to estimate the levels of some nitrogen and phosphorous species : Nitrite (NO2 -), Nitrate (NO3 -) Ammonium (NH4 +) and phosphate (PO4 -3) in waters of shatt Al-Arab from nine stations: (1) Qurnah (Tigris) (2) Qurnah Euphrates (3) Saad bridge (4) Qarmat Ali (5) Al-Najeebia(6) Ashar(7) Abu Al-khasib(8) Seeba and (9) Fao for the period October 2009 to September 2010. The higher concentrations of nitrite were recorded in the station 5 (Al-Najeebia) in march 2010 was 0.110 μgml and station 8) Seeba( in Jan 2010 was 0.095 μgml while the higher concentrations of Nitrate were recorded in station 7 (Abu Al-khasib) in Jun, July 2010 were 0.225,0.275 μgml respectively. The results indicated that (NH4 +) concentrations increasing during May, June and July 2010 especially in stations 5 and 6 was (0.95, 1.35),( 1.30, 1.25) and (1.45, 1.40 μgml) respectively. phosphate concentrations increasing during winter and spring 2010 especially in stations (Ashar, Abu Al-Khasib, Seeba,and Fao) 1.566, 2.033, 0.966, 1.266 μgml respectively. This can be attributed to increasing in temperature in summer, salinity of Shatt Al-Arab water and decay of organic and inorganic compounds in high temperature. | ||
