چکیده
زمینهوهدف: صنایع سیمان از آلاینده های صنعتی، به خصوص آلودگی فلزات سنگین محسوب می‌شوند. امروزه گیاه پالایی یکی از بهترین روش‌ها برای حذف و یا کاهش آلودگی فلزات سنگین می‌باشد. مطالعه حاضر با هدف بررسی توان گیاه پالایی کادمیوم، روی، سرب و منگنز بر روی گونه‌های عرعر، زبان گنجشک، اقاقیا، نارون‌چتری، اکالیپتوس، بلوط، سرو سیمین، کاج تهران و سرو شیراز در اطراف کارخانه سیمان ایلام انجام شد.
مواد و روش ها: برای اندازه‌گیری فلزات ترسیب شده در برگ گونه‌های مورد بررسی، 0/2 گرم از مادة خشک گیاهی (برگ) توزین و به هر نمونه 4 میلی‌لیتر اسید نیتریک 65 درصد اضافه شد و به مدت 24 ساعت در دمای اتاق قرار داده شدند. سپس توسط دستگاه جذب اتمیک مدل novAA-P400 میزان فلزات مورد نظر در نمونه ها قرائت شدند. تجزیه و تحلیل داده ها با استفاده از نرم‌افزار SPSS 20 و آزمون‌هایKolmogrov-Smirnov، Leven، وOne way Anova انجام شد.
یافته ها: نتایج نشان داد که میزان کادمیوم در الکتروفیلتر کارخانه تقریباً نزدیک به میزان کادمیوم ترسیب شده در برگ گونه ها می‌باشد، اما میزان سرب، روی و منگنز در الکتروفیلتر کارخانه خیلی بیشتر از میزان ترسیب این سه فلز در برگ گونه‌ها بود. بیشترین و کمترین مقدار ترسیب سرب به ترتیب مربوط به اکالیپتوس و سرو شیراز بود. علاوه براین بیشترین مقدار ترسیب منگنز در عرعر و کمترین میزان مربوط به کاج تهران بود. نتایج همچنین نشان داد بیشترین مقدار ترسیب روی مربوط به بلوط و کمترین مقدار مربوط به زبان‌گنجشک و بیشترین مقدار ترسیب کادمیوم مربوط به عرعر و کمترین مقدار مربوط به کاج تهران بود.
نتیجه گیری: گونه های پهن برگ ترسیب بیشتری از فلزات سنگین را دارند، لذا پیشنهاد می‌شود در برنامه‌های آتی توسعه فضای سبز، کاشت گونه های پهن برگ به ویژه گونه های بلوط، عرعر و اکالیپتوس در اولویت قرار گیرند.

چکیده [English]
Background and abjective: Cement factories are considered as one of the most important pollution sources, especially heavy metals pollution. At present, Phytoremediation is known as one of the best strategies to eliminate or reduce these pollutants. In the present study the phytoremediation ability of Cd, Zn, pb and Mn by nine trees species including Ailanthus glandulosa, Fraxinus rotundifolia, Robinia Pseudo Acasia, Ulmus umbraculifera, Eucalyptus microtheca, Quercus branti, Cupressus arizonica, Pinus eldarica and Cupressus sempervirens were investigated around the Ilam Cement Factory.
Material and Methods: For measuring the deposition of metals in the leaves of studied species, 0.2 grams of their biomasses were separately weighed then 4 ml nitric acid (65%) was added to each sample. After 24-hincubation at room temperature, the proportions of considered metals were determined by atomic absorption spectrometry.. The obtainedresults were analyzed by SPSS 20 software usingKolmogrov-Smirnov, Leven and One-way ANOVA Tests.
Results: Results showed that the amount of Cd in electro filter of factory was approximately close to the amount of Cd deposited in leaves of considered species, however; the amounts of pb, zn and mn in electro filter of factory were much more than the amounts of these three metals in leaves. The maximum and minimum accumulation of pb were related to Eucalyptus microtheca and Cupressus sempervirens respectively. In addition, the maximum and minimum amounts of deposited Mn were in Ailanthus glandulosa and Pinus eldarica respectively. The results also indicated that the maximum and minimum accumulation of Zn were in Quercus branti and Fraxinus rotundifolia respectively.
Conclusion: It can be concluded from the results; the broad-leaf species are much more efficient than narrow-leaf ones in heavy metals remediation, so; it is suggested that in future development plans of green space, the broad-leaf species, especially Quercus branti, Ailanthus glandulosa Desf and Eucalyptus microtheca are more considered.
