This study aims at investigating the effect of distance from source, species type and soil physical chemical properties on the absorption ability of heavy metals by tree species around the Nahavand cement factory. In the present research, soil and tree leaf (Pseudoacacia L, Populus nigra L, Elaeagnus angustifolia L, Fraxinus excelsior and Thuja orientalis L) samples were taken from 300, 500, 80...
Heavy metal accumulation in aquatic organisms has been an important issue due to environmental pollution resulting from anthropogenic activities. In this study, Cr, Mn, Fe, Cu, and Zn in the selected fish species (Mullus barbatus, Solea solea, and Siganus rivulatus) from three consecutive bays (İskenderun, Mersin, and Antalya from North-Eastern Mediterranean Sea) were considered to provide some...

the potential risk of metal accumulation in periurban agricultural areas is a matter for concern.the climate characteristics and carbonate content of calcareous agricultural mediterranean soils typical inthese areas favour metal accumulation at the surface level; however there is also a risk of potential metalmobility. our study focuses on the soil properties affecting metal mobility in these s...
Background: Due to environmental contamination in recent years, contamination of food chain by heavy metals is not far-fetched. The purpose of this study is to determine heavy metals in soybeans cultivated in Iran to monitor the food chemical contaminants. Methods: To assess metal contamination, four varieties (Sahar, Katool, Williams, and M7) of soybean cultivated in Iran, were collected. Met...
Plant growth, pigment concentration, biochemical parameters and uptake of heavy metals were determined for Brassica juncea L. in response to cadmium and lead stress. The plant exhibited a decline in growth, chlorophyll content and carotenoids with Cd and Pb but Cd was found to be more detrimental than Pb treatment in B. juncea. The protein content was decreased by Cd (900 μM) to 95% and 44% by ...
The task of modern agriculture is to safeguard the production of high quality food, in a sustainable natural environment under the precondition of pollution not exceeding accepted norms. The sustainability of current land use in agro-ecosystems can be assessed with respect to heavy metal accumulation in soils by balancing the input/ output fluxes. The objectives of this study were to model accu...
Chromium is a heavy metal toxic for plants that due extensive industrial applications over the last decade, has become a serious environmental pollution. On the other hand, chelator dissolution and absorption of metal by the plant increase and their use in phytoremediation is important. The aim of this study was to evaluate the effect of different concentrations of chromium and ethylene diamine...
Heavy metals including cadmium (Cd) and lead (Pb) are entering agricultural soils from different routes and mainly due to human activities. Accumulated Cd and Pb in the soil would eventually enter the human and animal food chains and pose threat to their health. Therefore, evaluating heavy metal accumulation is necessary to prevent soil and environmental pollutions and should be considered by r...
