[ 1 ] - تعیین غلظت کادمیوم در بافت‌های ماهی سفید (Rutilus kutum) و ارزیابی خطر مصرف آن در سواحل جنوبی دریای خزر

محصولات دریایی ﺑﻪ رﻏﻢ تأمین بخشی مهمی از پروتئین مورد نیاز انسان‌ها، موجب به‌وجود آوردن خطراتی برای سلامت آن‌ها می‌شوند. از این رو هدف از این مطالعه تعیین تجمع کادمیوم در بافت‌های پوست و عضله جنس‌های نر و ماده ماهی سفید و در نهایت مطالعه ارزیابی خطر مصرف آن می‌باشد.پس از انجام هضم اسیدی تعداد 30 عدد ماهی سفید نمونه‌برداری شده از سواحل جنوبی دریای خزر، میزان کادمیوم در آن‌ها با استفاده ا...

[ 2 ] - Evaluating the Potential of Plants (leaves) in Removal of Toxic Metals from Urban Soils (Case Study of a District in Tehran City)

Urban soil pollution has become a major concern in megacities around the world. Due to their non-degradable characteristic, toxic metals are among the most notorious pollutants. In this study determination of total and bioavailable fraction of toxic metals Ni, Cu, Cr, Zn, Co, Cd, Pb and Mn, in surface soils of district 16th in Tehran municipality is considered. Furthermore, metals uptake potent...

[ 4 ] - Removal of 2,4-dichlorophenoxyacetic acid and 4-chloro-2-methyl phenoxyacetic acid herbicides from aquatic environments by a novel polymer magnetic nanoparticles

Background and Objective: Increased use of pesticides and chemical fertilizers in agriculture in order to increase the productivity of fertile lands has led to pollution of water resources with a variety of pollutants, including herbicides. In this study, a new polymer magnetic nanoadsorbent named PV/S-g-3D-GO/N was synthesized and used to remove 2,4-D and MCPA herbicides from aquatic environme...
