[ 1 ] - Effects of Cadmium and Dimethoate on Some Biological and Biochemical Indices in Freshwater Green Algae, Spirogyra sp.
The present study investigates the influence of an organophosphorus pesticide, namely Dimethoate, and cadmium on biomarkers of the green alga, Spirogyra sp., in a 14-day experiment. For so doing, it has exposed Spirogyra sp. to 0.0, 100, 200, and 400 mg L-1 of Dimethoate and/or 1 mg L-1 of cadmium chloride (CdCl2) to observe a reduction in chlorophyll a and b level in Spirogyra sp., exposed to ...

[ 3 ] - بررسی ضریب همبستگی میان فلزات سنگین در جلبک Chaetomorpha sp، آب و رسوب در آبگیر تصفیه خانه های آب شرب محدوده رودخانه کارون
در مطالعه حاضر به منظور سنجش میزان فلزات سنگین (سرب، روی، کروم و کادمیوم) در رودخانه کارون از جلبک به عنوان شاخص زیستی استفاده گردید. بدین منظور نمونه برداری از جلبک غالب منطقه (Chaetomorpha sp.)، آب و رسوبات 6 ایستگاه در رودخانه کارون در فصل تابستان (1394) صورت گرفت. پس از هضم اسیدی نمونه ها، غلظت فلزات سنگین با استفاده از دستگاه جذب اتمی شعله اندازه گیری شد. نتایج نشان داد که میانگین غلظت سرب...
[ 4 ] - Evaluation of Heavy Metal Contamination and Ecological Risk Assessment in Sediments of Karun using Aquatic Pollution Indices
Background & Aims of the Study: The current study was designed to determine the quality of sediments in Karun in Ahvaz, Iran, according to aquatic pollution indices. Materials and Methods: The sediment samples were obtained from six river stations in summer and winter. The sediment samples were air-dried, sifted, homogenized, and stored in plastic bags, and the concentrations of metals were...
[ 5 ] - Bio-Accumulation of Lead and Cadmium by Radish (Raphanus sativus) and Cress (Lepidium sativum) under Hydroponic Growing Medium
In order to investigate the accumulation and bio-absorption of lead and cadmium in radish and cress, the present study has been conducted in a completely randomized design in three replicates in a hydroponic growing medium. The first factor includes the plant type at two levels (radish and cress), and the second factor is consisted of lead (Pb) (first experiment) at two levels (50 and 100 mg/L)...

[ 7 ] - Rare Earth Elements as Emerging Contaminants and Applications, Occurrence, Sources, and Environmental and Human Health Risks Caused by Them: A Review Study
Background and Objectives: Rare earth elements (REEs) are examples of emerging contaminants that have recently been increasingly spread to the environment through the extensive use in modern commodities, medical facilities, petroleum refining, mining, chemical fertilizers, electronic wastes and recycling plants. However, these elements are considered due to their potential human and ecological ...
