چکیده مقاله :

زمینه و هدف: از مهم ترین روش های بررسی فلزات سنگین، استفاده از گونه های ماکروفیت بعنوان پایشگر های زیستی می باشد که به عنوان شاخصی مناسب جهت بیان کیفیت محیط زیست مورد استفاده قرار می گیرند. در پژوهش حاضر به منظور بررسی وضعیت آلودگی تالاب هشیلان کرمانشاه و تأثیر گونه غالب گیاهی Phragmites australis در منطقه ، غلظت فلزات سنگین Cu, P b, Zn در اندام های زیرزمینی و هوایی گیاه نی و رسوبات سطحی تالاب، مورد مطالعه قرار گرفت. مواد و روش‌ها: آماده سازی نمونه ها با ا سید نیتریک، پر کلریک و پراکسید اکسیژن آن جام گرفت و غلظت عناصر مورد مطالعه با دستگاه جذب اتمی اندازه گیری گردید. یافته‌ها : نتایج حاصل نشان داد، غلظت فلزات مس، سرب و روی در رسوبا ت به ترتیب 23/17،47/6 و21/24 میکروگرم بر گرم می باشد. همچنین میانگین غلظت فلز مس در اندام های زیرزمینی و هوایی گیاه نی 738/2و190/2، فلز سرب143/15و02/13و برای فلزروی 11/6 و37/6 میکروگرم بر گرم وزن خشک بدست آمد که بیشترین تجمع فلزات در اندام های زیرزمینی گیاه بود. بالا بودن مقدار شاخص انتقال برای فلز روی بیانگر توانایی بالای انتقال این فلز در گیاه است. بحث و نتیجه گیری: در همین راستا بین غلظت فلزروی در اندام های زیرزمینی واندام های هوایی همبستگی مثبت و معنی داری وجود دارد؛ لذا احتمال می رود اندام زیرزمینی گیاه نی، پایشگری مناسب برای آلودگی ناشی از عنصر روی در رسوبا ت منطقه باشد.

چکیده انگلیسی:

Background and Objective: One of the most important methods to investigate heavy metals is to apply bio-monitors used as an appropriate index to express the environment quality. In this study, the concentrations of such heavy metals as Zn, Pb and Cu in the underground and aerial organs of Phragmites australis were investigated to study the pollution status in Hashilan Pond, Kermanshah and the effects of dominant species called Phragmites australis in the region. Method: The samples were prepared by nitric acid, perchloric acid and peroxide oxygen and afterwards, the concentrations of elements were measured by the atomic absorption spectrometry. Findings: Results demonstrated that the concentrations of copper, lead and zinc were estimated at 47.23, 6.17 and 24.21 in the sediments, respectively. Also, the mean concentrations of copper, lead and zinc were 2.738-2.190, 15.143-13.02 and 6.11-6.37 mg-1in the underground and aerial organs, respectively; furthermore, the highest metal concentration was related to the underground organs of plant. High values of transfer index concerning zinc indicated high ability of zinc transfer in the plant. In this regard, a positive significant correlation exists between the concentration of zinc in the underground and aerial organs; Discussion and Counclusion: Therefore, the underground organs of reed are introduced as a suitable monitor for the resultant pollution of zinc in the regional sediments.
