Sediments represent a critical compartment of marine coastal ecosystems due to the toxic and long-lasting effects contaminants buried therein. Here, we investigated properties surficial sediments in front Southern Marche Region coast (Central Adriatic Sea, Italy). The grain size was determined by X-ray sedigraphy. TN OC contents were elemental analysis. concentrations Al, Fe, Mg, K, S, Ca, Ti, ...

Introduction: Heavy metal pollution is one of the most serious environmental issues globally.In this research we were studied the heavy metal concentrations in sediment and fish in Persian gulf. Materials & Methods For determination of heavy metal concentrations in sediments 8 sampling stations were selected to measure Cd, Zn, Ni, Pb and Fe in the sediments and in the muscle tiss...

The river environment is complex and receives a variety of contaminants from numerous sources that are persistent, bioaccumulative, toxic. distribution, source, contamination, ecological risk status Zn, Pb, Cu, Ni, Cr, Cd were evaluated in the surface sediments at 45 sites on Moyang Jian rivers Western Guangdong, China. Single pollution indices, including contamination factor (CF) enrichment (E...

ABSTRACT This study aims to evaluate potential ecological risks and heavy metal pollution in sewage sludge. For these purposes, domestic sludge samples were collected for a period of one year from wastewater treatment plant Bursa, Turkey analyzed metals. The average content the was wherein decreasing order Zn>Cu>Ni>Cr>Pb>As>Se>Cd. As whole, concentration metals below limit values indicated with...

Some trace elements in various lichens as biomonitors of pollution were investigated. Also, the status was assessed by enrichment factor, contamination and loud index. Investigated Ta, Bi, Hf, Nb, Ga, Sc, Li, Y, Ce, Sr. The lichen species Rhizoplaca chrysoleuca, Umbilicaria vellea, Aspicilia calcarea, Pseudevernia furfuracea, Cetraria islandica. According to results, accumulate Sr element well....

This paper describes the concentration of selected heavy metals (Co, Cu, Ni, Pb, and Zn) in the Mamut river sediments and evaluate the degree of contamination of the river polluted by a disused copper mine. Based on the analytical results, copper showed the highest concentration in most of the river samples. A comparison with Interim Canadian Sediment Quality Guidelines (ICSQG) and Germany Sedi...

Present study consists geochemical variations and spatial distribution of trace elements (Fe, Mn, Cr, Co, Cu, Ni, Pb and Zn) of the ocean floor sediments collected along the continental shelf off East coast Tamil Nadu (Chennai to Velanganni) during the 2009 southwest monsoon period. Results indicate sand dominance with abundant calcareous debris and shell fragments. Normalisation of trace metal...

The water quality of the Persian Gulf is influenced by various industrial and urban discharges. The study area is a small linked estuary with the Straits of Hormuz in the Persian Gulf. This study was conducted to evaluate anthropogenic assessment, pollution status and potential ecological risk of some heavy metals (Pb,Ni, Zn, and Fe) in intertidal surface sediments of a mangrove estua...

Environmental enrichment (EE) increases dentate gyrus (DG) neurogenesis and brain-derived neurotrophic factor (BDNF) levels. However, running is considered an element of EE. To dissociate effects of physical activity and enrichment on hippocampal neurogenesis and BDNF levels, young female C57Bl/6 mice were housed under control, running, enrichment, or enrichment plus running conditions, and inj...
