The impact of human activities on some water properties of the Tigris River in Baghdad Governorate

Abstract

The study was conducted to determine the impact of activities, including industrial activity, represented by the Taji, Al-Rashid, and Doura power stations, agricultural activity of agricultural lands overlooking the Tigris River in Taji and Doura, and service activity, represented by the Bouaitha sewage station, on some properties of the river water. The research included an analysis of 10 standards, pH, turbidity, and electrical conductivity E.C. Chlorides CL, carbonates Co3, phosphorus Po4, hydrogen sulfide H2S, The biological oxygen requirement (BOD), the chemical oxygen requirement (COD), and radioactive materials. The results of the study showed that the pH took the basic side in industrial and service activities, while it took the acidic side in agricultural activity. The results of turbidity are outside the environmental determinants for both industrial and service activities But they are among the determinants of agricultural activity, while electrical conductivity was among the environmental determinants, and the percentages of carbonates and hydrogen sulfide recorded values ​​exceeding the permissible limit in service activity, while chlorides, phosphorus, the biological and chemical requirement for oxygen, and materials with radioactivity were exceeding the permissible limit within the Iraqi and international standards
