دراسة التلوث بالمتغيرات الفيزيوكيمائية وعنصري من العناصر الثقيلة (الحديد والنحاس) للمياه الصناعية والمطروحة من معمل الاسمنت وشركة غاز الشمال في مدينة كركوك

Abstract

The study included the quality of industrial water from the cement plant and the North Gas Company in the city of Kirkuk. Water samples were collected October 2017 to February 2018. Chemical and physical tests were conducted, including temperature estimation, electric conductivity (EC), total soluble solids (TDS) , (pH) , phosphates (PO-24) , nitrates ( NO-13) , sulphates (SO-24) and chlorides (CL-1) The results of physical analysis,( temperature, conductivity (EC), and soluble solids (TDS) were found to be higher than Iraqi standard limit except for temperature. The chemical anaylsis results showed that the water was characterized by the rise of the most chemical properties such as,( pH (8.49) , phosphates (3.29), nitrates(27.5), sulfates( (353.5, and chlorides(310.6)) mg/l which exceeded the environmental determinants except for nitrate sulfate and chlorides which were within Iraqi standards .The second stage included industrial water pollution and heavy Metals such as iron and copper (Fe - Cu) . It was found that the iron element had a concentration(5.57)mg/l higher than the permissible limit. While the concentration of copper(0.183) mg/l was less than the limit allowed locally and globally. The results were analyzed using the F( ANOVA) test. The mean was measured using the Duncan Multidimensional Test with probability level (0.05) by applying the Duncanes multiple range program. Morphological differences were determined by the use of letters. Similar letters mean that there are no significant differences between them.
