mapping based on total concentrations of micronutrients may be useful in fertility management including fertilizer and/or wastewater application. the aims of this work were to (1) investigate the spatial distribution of total concentrations of copper (cu), zinc (zn), manganese (mn) and iron (fe); (2) to select the suitable spatial estimator; and (3) to understand the effect of wastewater irriga...

soil reduces the hazardous effects of compounds on the components of ecosystem because of self –purification property and the ability for their fixation. playing such a role in soils under redox conditions is performed by pedogenic fe-mn concentrations. in order to investigate cobalt, copper and lead accumulation in iron and manganese concentrations, at first the concentrations were precisely s...

concentrations of six heavy metals including cr, mn, ni, pb, v and zn were determined in topsoil (from 47 grid cells), surface water (4 streams) and groundwater (8 wells and 4 qanats) from an agriculturalarea located at south part of the iranian capital, near the tehran oil refinery. concentrations of the elementswere measured using flame and flameless atomic absorption spectrometry. based on t...

since heavy metals are considered as one of the major pollutants threatening, the main goal of this study was to bring out the concentrations of pb, zn and mn in the surface sediments off bushehr in the persian gulf. for this purpose, after collection of samples, the concentrations of the three metals in surface sediments were measured through the atomic absorption. the results were compared wi...

background: iron, manganese, and aluminum are three abundant metals on earth and their concentrations have increased in aquatic environments as a result of natural and industrial activities. this study was undertaken to report the median acute toxicity (lc50) and accumulation of the sub-lethal concentration (10% 96-h lc50) of iron (fe), manganese (mn) and aluminum (al) in kutum (rutilus kutum) ...
