In this study, the concentrations of heavy metals (Ca, Zn, Cu, Fe, Mn, Ni) in thesediment of Shavoor River in Khuzestan Province in Iran has been investigated. After the library studies and field studies, six samples of water and sediment were taken from the river in order to evaluate heavy metal pollution in sediments. To determine the geochemical phases of metals in sediment samples the 5-ste...

the  present study was aimed  at comparing the ability of three crop plants for phytoremediation of zinc (zn) and nickel (zn) from soils. a factorial (3×2×3) experiment based on rcbd was  used to compare the treatments,  and was repeated three times. the first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (zn) and nickel (ni)) and the third fac...

As a result of the continuous urbanization and industrialization in China over the last few decades, heavy metals have been continuously emitted into urban environments and now pose serious threats to human health. In the present study, an extensive urban near-surface dust survey was conducted in Changchun, China, to evaluate the current status of heavy metal contamination in urban dust and to ...

Accurate monitoring of heavy metal stress in crops is of great importance to assure agricultural productivity and food security, and remote sensing is an effective tool to address this problem. However, given that Earth observation instruments provide data at multiple scales, the choice of scale for use in such monitoring is challenging. This study focused on identifying the characteristic scal...

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...

in recent years, heavy metal contamination of rice in different parts of the world has raised concerns about its safety and provoked crisis in it's global production and trade. in iran, also some studies have reported on the heavy metal contamination of native products. however, the concentration of heavy metals in rice grain could be influenced through preparation and cooking. this study aimed...

An effective method to monitor heavy metal stress in crops is of critical importance to assure agricultural production and food security. Phenology, as a sensitive indicator of environmental change, can respond to heavy metal stress in crops and remote sensing is an effective method to detect plant phenological changes. This study focused on identifying the rice phenological differences under v...

Introduction: Uncontrolled and improper landfilling of solid waste increases the concentration of heavy metals in the soil. Therefore, this study aimed to investigate soil contamination with heavy metals in the landfill of municipal and hospital waste in Sabzevar city by compiling a map of the severity of heavy metal pollution in the soil. Materials and Methods: Concentrations of heavy metals ...
