Agriculture plays an important role in the sustainable development of country. Use chemical fertilizers escalate certain components excess quantity thereby deteriorate productivity and leads to unpredicted outcome. This study makes effort reckon accumulation some selected heavy metals [Lead (Pb), Nickel (Ni) Cadmium(Cd)] related indices [bio concentration factor(BCF) translocation factor (TF)] ...

Red Sea coastal development has rapidly accelerated in recent decades that led to a rise the anthropogenic heavy metal levels sediments. A total of 80 surficial sediment samples were collected from shallow waters along eastern coast near Jeddah, Saudi Arabia. These three locations, designated as North, Middle and South assess concentrations six metals: chromium (Cr), manganese (Mn), nickel (Ni)...

The main purpose of the research was to analyze distribution Arsenic (As), Cadmium (Cd), Copper (Cu), Iron (Fe), Nickel (Ni), Cobalt (Co), Mangan (Mn), and Zinc (Zn) in soft tissues, shells, associated surface sediments Cerithidea obtusa (C. obtusa) mangrove snails collected from Sungai Besar Sepang. concentration iron (Fe) found be highest relation other toxic elements sediments, shells C. obt...

To better understand heavy metal pollution and the potential ecological risk of mangrove sediments in Nanliu River estuary, speciation distribution characteristics metals Fe, Mn, Zn, Co, Ni, Cd, Cr, Cu, Pb 13 surface study area were determined analyzed using a modified four-step BCR extraction method, was assessed Geo-accumulation Index (Igeo), Potential Ecological Risk (RI), Assessment Code (R...

In order to investigate concentrations, variability, sources, and human health risk of trace elements, 38 atmospheric dust samples were collected around Arak industrial area. The average concentrations Cd~Zn, As, Pb 3.3, 2.5, 2.4 times higher than the corresponding geochemical background, respectively, while Co, Cu, Ni, Hg lower. Based on geo-accumulation index (Igeo), elements classified betwe...

Background & Aims of the Study: Regarding to development of industry, soil contamination has become a serious problem in many countries, such as Iran. The aim of the present work was the illustration of the accumulation of potentially harmful trace elements and the potential risk which is posed to human health in surface soils of three industrial estates of Aran-o-Bidgol city, Isfah...

It is a well–known fact that heavy metal pollution in sediments causes serious problems not only the Danube basin, but also large and small adjacent river streams. A suitable method for assessing level of metals their toxicity calculation indices. The present research aims to assess Lower surface collected along course (between 180 60 km) up point where River flows into Delta Biosphere Reserve ...

Constructed wetlands are an affordable and reliable green alternative to conventional mechanical systems for treating domestic sewage. This study investigates the potential of 14 tropical wetland plant species removing heavy metals from sewage through bioconcentration factor (BCF), translocation (TF), enrichment (EF), geoaccumulation index (Igeo) using batch mesocosm studies. Plants with BCF &g...

Background & Aims of the Study: Heavy metals are the most important contaminants in the soil. Due to their non-biodegradable property, heavy metals can persist in the ecosystem for a long time. Therefore, this research focuses on heavy metal contamination in urban park soils in Asadabad, Hamedan, Iran. Materials & Methods: Altogether 18 composite soil samples were collect...
