ملخص المقالة :
زمینه وهدف: رسوبات به‌عنوان مهم ترین محل ذخیره و جذب فلزات و آلاینده های دیگر در اکوسیستم‌های آبی محسوب می‌شوند و می‌توانند کیفیت سیستم‌های آبی را منعکس کنند. در این مطالعه میزان آلودگی رسوبات به فلزات روی، مس، سرب و کادمیوم براساس شاخص بار آلودگی (PLI) و ارزیابی میزان خطرات عناصر فلزی بر روی موجودات زنده براساس شاخص اولویت‌بندی پتانسیل خطرات بیولوژیک (MERMQ) در رسوبات سطحی رودخانه‌های سواحل جنوبی شرقی دریای خزر انجام شد. روش بررسی: به منظور سنجش و تعیین شاخص‌های آلودگی فلزات، نمونه‌برداری از رسوبات سطحی مصب و فاصله 1000متر از مصب برخی رودخانه های سواحل جنوب شرقی دریای خزر شامل گرگان‌رود، قره سو، نکاءرود ، تجن ، تالار و بابلرود انجام پذیرفت. نمونه‌ها در آزمایشگاه با استفاده از مخلوط سه اسید نیتریک، فلوریدریک و کلریدریک آماده‌سازی گردید و سپس به وسیله دستگاه جذب اتمی مورد آنالیز قرار گرفتند. یافته‌ها: نتایج تحقیق حاضر، گویای آن است کهمیزان شاخص MERMQ عناصر فلزی در رسوبات رودخانه‌های سواحل جنوبی دریای خزر بین 073/0 تا 12/0 و میزان شاخص آلودگی PLI بین 36/0 تا 58/0 متغیر بوده است. نتایج مقایسه غلظت فلزات در نمونه‌های رسوب سطحی با استاندارد کیفیت رسوب (NOAA) نشان داد که در تمام ایستگاه‌های مورد مطالعه مقدار عناصر اندازه‌گیری شده کم‌تر از مقدار ERL می‌باشد. نتیجه‌گیری: نتایج شاخص اولویت‌بندی پتانسیل خطرات بیولوژیک ((MERMQ برای رسوبات نشان داد که در مصب رودخانه های قره‌سو، تالار و فاصله 1000متر از مصب رودخانه بابلرود از لحاظ اولویت‌بندی میزان خطرات بیولوژیک در سطح اولویت پایین تا متوسط قرار دارد و در دیگر ایستگاه های مورد مطالعه در اولویت پایین قرار گرفته اند. نتایج شاخص آلودگی PLI نشان داد که میزان آلودگی رسوبات به فلزات در سطح آلودگی کم می باشد. نهایتاً می توان اشاره نمود که اعمال رهنمودهای مدیریتی صحیح از قبیل، دفع اصولی فاضلاب های شهری، روستایی و صنعتی، استفاده از آفت‌کش های مناسب و همچنین مطالعات هم‌زمان غلظت عناصر در آب، رسوب و جانداران در رودخانه ها به صورت دوره‌ای می تواند در بهبود وضعیت فعلی منطقه موثر باشد.
