چکیده

در این مطالعه به بررسی کیفیت آب رودخانه ازنا بر­ اساس عناصر اصلی و سنگین پرداخته شده است. نتایج نشان داد، واکنش ناشی از سازندهای منطقه از عوامل کنترل­کننده عناصر اصلی و سنگین در آب­ های سطحی منطقه است. باتوجه به مطالعات آماری، اعمال روش تحلیل مؤلفه­های اصلی بر­اساس عناصر اصلی و سنگین در منطقه مشخص شد بیشترین میزان همبستـگی بین مجموع مواد جامد محلول و کلر می­باشد و آزمون تحلیل رگرسیون خطی کاتیون­ها، آنیون­ها و هدایت الکتریکی به­عنوان متغیر وابسته در مقابل مجموع مواد جامد محلول به عنوان متغیر مستقل همبستگی بالایی بین مواد جامد محلول با هدایت الکتریکی و کلر در نمونه­های مورد مطالعه نشان می­دهد. از نظر عناصرسنگین در منطقه مورد مطالعه میزان عنصر کادمیوم بیش از مقدار استاندارد بین المللی است و سایر عناصر در محدوده استاندارد قرار دارند. درمنطقه مورد مطالعه بالاترین همبستگی بین روی با کادمیوم و منگنز با کروم وجود دارد.

چکیده [English]

Surface water quality is largely influenced by physical processes, chemical and biological processes such as weathering of minerals, rocks, climate and precipitation amount. Human activities (domestic and industrial wastewater, atmospheric sediment, irrigation return flow, etc.) also can reduce the quality of surface water and disrupt using it for drinking, industrial and agricultural consumption. The investigation of saturation index changes is useful to determine the different stages of the evolution of hydro chemical and chemical reactions to control the water chemistry. The control processes of water chemistry including physical, chemical and biological processes, structural, geological and mineralogical composition of the host rocks, and human activities such as household and industrial wastes, excessive use of chemicals and pollution emissions of wastewater tanks can effectively affect the surface water chemistry. Hierarchical clustering methods are appropriate methods for data analysis of water samples which are applied to assess the water quality data and the possibility of sample hydrochemical grouping having the highest importance of the statistical viewpoint in hydrology, hydrogeology and geology. In this study, Azna river water quality has been investigated based on the major elements and heavy metals. Results showed that the reactions due to area formations are the factor that affects the major elements and heavy metal in the surface waters of area.
