Abstract
The study was conducted on the water quality of Tigris River in upstream of AL-Kut Barrage during the period of August 2018 to June 2019. Six vertical sections have been selected upstream of Al-Kut Barrage. The distance between one section to another was 100 m, the first section begins at 350 m from the origin of Barrage. The result showed that the values of cadmium ion were 0.0346 ug/L to 0.0707 ug/L. The Lead values of the Tigris River water samples were 4.29 ug /L to 8.33 ug /L. The values of nickel ion have been ranged between 7.59 ug/L to 9.75 ug/L. Zinc ions have been recorded 53.5 ug /L to 72.1 ug /L. The concentration of above ions was situated within Iraqi and world Health organization (WHO) criterions that relating with propriety of water of Tigris River for drinking and irrigation.
Highlights
Water quality is indicator of the suitability of water using by humans, animals and plants [1]
The cadmium values in the Tigris River water samples and for all sections were within the permissible limits, according to the Iraqi, the World Health Organization world Health organization (WHO) and Canadian standards, the results have been recorded 0.003, 0.0051, 0.0002 ppm respectively (Fig. 1), whether for drinking, irrigation or aquatic biology purposes
The results showed that the lead values in the Tigris River water samples and for all sections were within the permissible limits. according to the Iraqi and the World Health Organization WHO and Canadian standards, samples were recorded 0.01, 0.2, 0.007 ppm respectivety, except the sections S1, S3, and S6, whose water samples were brought on 27/4/2019 and were outside the permissible limits (Fig. 2)
Summary
Water quality is indicator of the suitability of water using by humans, animals and plants [1]. The used water that used in different activity contains a lot of dissolved salts in different concentration and ionic composition. This is coming with negative results on chemical and physical properties of the soil and productivity of plants. According to International Food and Agriculture Organization (FAO), the water quality depends on the total concentration of salts as the main quality factor for the use of irrigation water [8]. Heavy metals in the environments indicate that it is exposure to contamination [9], indicated that the concentration of these elements in the river depends on the temperature, salinity, pH, organic and mineral materials. The aims of this study: 1- Study of the elements in Tigris River and their effect on water quality. 2- Determine the heavy elements in the Tigris River. 3- Study the water quality and its suitability for agriculture
