Assessment of Ecological Hazard of Heavy Metals (Cr, Zn, Cu, Pb) in Surface Sediments of The Bashar River, Yasouj, Iran
Background & Aims of the Study: Heavy metals pollution in aquatic ecosystems threats living organisms' health and environment. Hence, the present study aims to assess concentration of lead, chromium, copper, zinc and their ecological risk in the surface sediments of the Bashar River during the summer and winter seasons. Materials & Methods: This is a field study; sampling of...
متن کاملPhosphorus cycling in sediments of the Bohai and Yellow Seas
Using a box-sampler, surface and core sediment samples were collected from the Bohai and Yellow Seas in 1998e1999. The sediments were sequentially extracted to determine six phosphorus fractions, and non-sequentially extracted for total P (TP) and inorganic P (IP), where the difference between TP and IP was assumed to be organic P (OP). It was found that more than 70% of the total P is inorgani...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Heavy Metals Contamination in Sediments from the North of the Strait of Hormuz
The objective of this study was determining the heavy metal contents in sediment along the coastlines of Hormuzgan province. Sediment constitutes are important part of aquatic ecosystems. They provide habitat for benthic organisms and could be a significant sink as well as a potential source of contaminants. Three sources of heavy metals pollution in this area are industry, natural mineral...
متن کاملOrganic Carbon and Organic Matter Levels in Sediments of the Strait of Hormoz, the Persian Gulf
Total organic carbon has a major influence on both the chemical and biological processesthat take place in sediments. Algal bloom is one of the organic carbon levels in aquatic ecosystems. In 2009 algal bloom occurred in the Hormozgan province and prolonged for months, which finally setteled down in 2010. In this study the variations of total organic carbon (TOC), organic matter (TOM) and tot...
