| چکیده | ||
| امروزه منابع آب ذخیره‌شده در مخازن سدها یکی از منابع اساسی تأمین آب شرب محسوب میشوند. عناصر موجود در رسوبات مخازن سدها از مهمترین عوامل مؤثر بر کیفیت آب هستند. به‌دلیل مشکلات ناشی از کمآبی، بر‌خلاف برنامهریزیهای اولیه، امروزه تقریباً همۀ آب ذخیره‌شده در مخزن سد کارده به شرب اختصاص داده شده است. از طرف دیگر، در سطح حوضۀ آبریز این سد تغییرات زیادی از نظر کاربری اراضی، توسعۀ اراضی کشاورزی و احداث باغ‌ـ ویلا صورت گرفته است. بنابراین، بررسی وضعیت آلودگی رسوبات مخزن این سد نسبت به عناصر سنگین ضروری است. در این پژوهش ابتدا با مغزهگیری از رسوبات مخزن سد کارده، مقادیر 9 عنصر سنگین در رسوبات با استفاده از دستگاه ICP-OES تعیین و با استفاده از معیارهای کیفی استاندارد رسوبات، وضعیت آلودگی رسوبات مخزن سد به عناصر سنگین بررسی شد. سپس با تعیین دانهبندی رسوبات توسط دستگاه Nano particle size analiyzer، رابطۀ اندازۀ ذرات با میزان و نوع عناصر سنگین موجود در رسوبات بررسی شد. بر‌اساس استانداردهای استفاده‌شده، تقریباً همۀ عناصر بررسی‌شده در حد مجاز قرار دارند. به نظر میرسد که منشأ این عناصر آلایندههای محلی باشد و ناشی از انتقال رسوبات از تشکیلات زمین‌شناسی نواحی بالادست نیست. از طرفی، روند تغییرات اندازۀ ذرات در مخزن سد نشاندهندۀ تأثیر‌پذیری این ذرات از عمل فلاشینگ است. | ||

| چکیده [English] | ||
| Today, water resources stored in reservoirs is one of the basic sources of drinking-water. The elements in the sediments of reservoirs are the most important factors affecting water quality. Unlike the primary plan, due to water shortage problems, nowadays, almost all the stored water in the Kardeh reservoir is allocated to drinking water. From the other side in the catchment area of this dam a lot of changes in terms of land use, the development of agricultural lands and the construction of the garden-Villa Has taken place. Therefore, Surveying the status of the reservoir sediment contamination by heavy metals is essential. In this research, first some cores of sediments from the reservoir was taken and the amounts of 9 heavy metals elements in the sediments were determined using ICP-OES. Reservoir sediment contaminations by heavy metals were studied, by using qualitative criteria of sediments. Then determine the aggregation of sediments by Nano particle size analiyzer machine, the relationship between the particle size with the amount and the type of heavy elements present in the sediments were studied. Based on the standards criteria, almost all the elements are at the acceptable ranges. It seems that the origin of these elements has been the local pollutants and not from sediments resulting from the transfer of the geological structure of the upstream areas. On the other hand trend of changes in particle size in the reservoir reflects the impact of flushing. | ||
