| چکیده | ||
| فلزات سنگین به خصوص جیوه به علت سمیت، پایداری و اثرگذاری بر روی موجودات آبزی از نظر سلامت عمومی حائز توجه و اهمیت هستند. در این مطالعه به منظور بررسی غلظت جیوه در رسوبات بین جزر ومدی خوریات ماهشهر در استان خوزستان، 8 ایستگاه انتخاب و از هر ایستگاه سه نمونه رسوب برداشت شد. عملیات نمونهبرداری در دی ماه 1394 انجام شد. پس از تجزیه و تحلیلهای آزمایشگاهی، محتوای جیوۀ آنها با استفاده از دستگاه جذب اتمی و به کمک تکنیک بخار سرد سنجیده شد. میانگین غلظت جیوه در رسوبات ایستگاههای مورد بررسی در محدودۀ 490- 90 نانوگرم بر گرم قرار داشت. مقادیر بالای جیوه در خور پتروشیمی یافت شد و با افزایش فاصله از این خور به تدریج از میزان آلودگی کاسته میشد. به طور کلی محاسبۀ فاکتور آلودگی منطقهای، آلودگی خیلی شدید را برای اکثر ایستگاهها نشان داد، درحالی که بر طبق فاکتور آلودگی جهانی، میزان آلودگی در حد کم تا متوسط قرار داشت. | ||

| چکیده [English] | ||
| Heavy metals, especially mercury due to its toxicity, persistence and the impact on aquatic organisms is important in terms of public health noteworthy. This study aimed to assess mercury concentrations in surface sediments of estuaries Mahshahr, Khuzestan province, eight stations were selected and three sediment samples were collected from each station. Sampling operations were conducted in January 2016. After laboratory analysis, the content of mercury using cold vapor atomic absorption technique was measured. The average concentration of mercury in sediments of stations studied in the range of 90-490 was nanogram per gram. High levels of mercury were found in petrochemical estuary and with increasing distance from this estuary, the pollution of the gradually decreased. In general, the calculation for regional factor pollution, pollution is too severe for most stations showed, while According to global factor pollution was low to moderate. | ||
