| چکیده | ||
| به‌منظور ارزیابی گونههای گیاهان آبزی به‌عنوان موجودات شاخص در پایش اکوسیستمهای آبی، هدف از انجام این مطالعه تعیین میزان تجمع فلزات سنگین روی، مس، کادمیوم و سرب در رسوبات، ریشه، ساقه و برگ گیاهان آبزی Phragmites australis،Myriophyllum spicatum و perfoliatus Potamogeton 2 ایستگاه شمالی و جنوبی رودخانۀ دز است. از هر ایستگاه 3 نمونه رسوب سطحی (تا عمق10 سانتیمتر) به وزن حدود 700 گرم برداشته و نمونهبرداری از اندامهای مختلف گیاهان انجام شد. برای سنجش فلزات سنگین از دستگاه جذب اتمی مدل (Perkin Elmer4100) استفاده شد و به‌منظور حصول اطمینان از درستی نتایج به‌دست‌آمده برای دادههای بافت گیاهان از مادۀ مرجع 3-DORM استفاده شد. نتایج نشان داد که فلز روی و کادمیوم به‌ترتیب بیشترین و کمترین تجمع را در رسوب ایستگاههای مطالعه‌شده داشته و میزان آنها از 33/55 ±67/270 تا 22/50 ±33/240 و 09/0 ±10/1 تا 06/0 ±60/1 میلی‌گرم بر کیلوگرم وزن خشک متغیر بود. الگوی تجمع فلزات مطالعه‌شده به‌ترتیب روی> مس> سرب> کادمیوم بود. در گیاه حاشیهای نی بیشترین تجمع فلز روی در ریشه 22/60±45/300، برای گیاه غوطه‌ور مریوفایلوم در ساقه 66/20±43/104 و پوتاموژتون در برگ 44/21 ±35/122میلی‌گرم بر کیلوگرم وزن خشک مشاهده شد. نتایج بیانگر این نکته بود که هر سه گیاه پتانسیل جذب فلزات سنگین را داشتند و برای هر عنصر انتخابی عمل کردند و میتوان از آنها برای پایش محیط استفاده کرد. | ||

| چکیده [English] | ||
| In order to evaluate the Phragmites australis, Myriophyllum spicatum and Potamogeton perfoliatus aquatic plant species as an indicator organism of heavy metals pollution in bio-monitoring studies of the aquatic ecosystems, the aim of this study was to determine the levels of heavy metals accumulation Zn, Cu, Pb and Cd in sediments, roots, stems and leaves of these plants in north and south of two stations of Dez River. 3 samples of surface sediment (to 10 cm depth) with 700 g weight of each station by plastic tools were collected and sampling was carried out of each different organ of plants. Results showed the highest and lowest of metals were measured in sediment Zn (270± 55.33 ppm) to (240.33± 50.22 ppm) and Cd (1.10± 0.09 to 1.60± 0.06 ppm), respectively. The concentrations of heavy metals in sediments and plants poses the same trends: Zn> Cu> Pb> Cd. The highest of Zn by Ph. australis in root (300.45± 60.22 ppm), M. spicatum in stem (104.43± 20.66 ppm) and P. perfoliatus in leaves (122.35± 21.44 ppm) were showed. According to results, three plants were showed potential for heavy metals and for each metal selectivity and could use for environmental monitoring. | ||
