Studying the Seasonal Changes of some Heavy Metals and Chemical Properties in Main Outfall Water and Evaluating Their Suitability for Irrigation Purposes

Abstract

Abstract A study was conducted for the purpose of evaluating some chemical properties of main outfall water within the city limits of Babylon to demonstrate its suitability for irrigation purposes pH, Electrical conductivity, Calcium, magnesium, sodium, potassium, chloride, carbonate, bicarbonate, sulfate, nitrate, and Boron and some were estimated Heavy metals (Cadmium, Lead, Copper, and Nickel) in four time periods (June 2023, September 2023, December 2024, March 2024) and for the regions (Latifiya, Suwaira, Maamra, and Shomali). The results showed that the salinity of the main outfall water falls within the category that causes a severe salinity problem, and that the degree of reaction of the water is within the normal range, tending to light alkalinity, and that the sodium values increase towards the main outfall towards the south, and falls within the category that shows a severe salinity problem, and that the chloride concentrations were They are all located within waters that cause a severe problem for the classification. The boron problem was slight to moderate for sensitive crops. The main outfall water is classified as no problem in terms of its nitrate content. Concentrations of heavy metals in main outfall water follow the following sequence: Cd < Ni <Pb< Cu.
