introduction: the accumulation of heavy metals (hms) in the soil is of increasing concern due to food safety issues, potential health risks, and the detrimental effects on soil ecosystems. hms may be considered as the most important soil pollutants, because they are not biodegradable and their physical movement through the soil profile is relatively limited. therefore, root uptake process may p...

Heavy metal contamination in lake sediments is a serious problem, particularly in developing countries such as China. To evaluate heavy metal pollution and risk of contamination in lake sediments on a national scale in China, we collated available data in the literature of the last 10 years on lake sediments polluted with heavy metals from 24 provinces in China. Based on these data, we used sed...

This study investigated the impact of air pollution on the spectral reflectance of the epiphytic lichen Ramalina lacera, indicated by the normalized difference vegetation index (NDVI), on the integrity of chlorophyll, indicated by the ratio OD435 nm/OD415 nm, and on the integrity of cell membranes, indicated by electric conductivity. Data relating to physiological parameters of injury were inte...

In the present study, impact of tannery and other industrial effluents on the physico-chemical characteristics of loamy drain water and their consequent impact on soil and plants irrigated with effluent have been studied. The study reveals most of the parameter pH, BOD5 and COD at sampling station I was higher than station II. Waste water quality at both Stations I and II exceeded prescribed li...

In this study, we evaluated the possible role of Ligia italica as a bioindicator for the monitoring of heavy metals pollution in the suppralittoral zone of marine rocky coasts. Between 2004 and 2011 specimens of L. italica were collected along the Eastern Sicilian coasts from sites known for their high pollution levels as they are near to an area where in September 2001 a refinery plant dischar...

In the last three decades, the industrial and human activities in the coastal area of Saudi Arabia have increased dramatically and resulted in the continuous invasion of different types of pollutants including heavy metals. Seven sediment cores were collected from three major industrialized areas; Jeddah, Rabigh and Yanbu, along the coast of Saudi Arabia to determine the spatial and temporal di...

salicylic acid-formaldehyde-m-cresol (sfm) terpolymer had been synthesized in dmf media by conventional method. the resulting resin had been characterized by ftir spectra, elemental and thermogravimetric analyses. the morphology of sfm resin had been studied by sem and optical photograph. various parameters like rate of equilibration, effect of ph on ion exchange capacity and effect of concentr...

Background and Purpose: The Phytoremediation efficiency of heavy metals is one of the important points in environmental studies. This research was conducted to investigate the effect of cow manure, elemental sulfur, and EDTA on Cd uptake by Indian mustard in a Cd-polluted soil in the presence of Thiobacillus thiooxidans. Materials and Methods: Treatments consisted of applying cow manure (0, 5,...

in this research, the effect of air pollution on proline concentration, soluble sugar, anatomical and morphological features was studied in two plant species malva parviflora and hordeum glaucum in 2009. the area of the stand steel factory of khuzestan was considered as the polluted site and shush region was considered as the control site, and sampling was carried out from the two sites, accide...

The nature of surface complexes formed on Ni uptake onto montmorillonite (a dioctahedral smectite) has been investigated over an extended time period by polarized extended X-ray absorption fine structure (P-EXAFS) spectroscopy. Self-supporting films of Ni-sorbed montmorillonite were prepared by contacting Ni and montmorillonite at pH 7.2, high ionic strength (0.3 M NaClO4), and low Ni concentra...
