Heavy metals are considered as one of the important pollutants in the environment, particularly in the aquatic ecosystems. The presence of cadmium in food chain is toxic to human health. Different physical or chemical methods have been used for removing heavy metal ions in the water and wastewater treatments. The aim of this work was to assess the possibility of Cd removal from aqueous solution...
Background and objective: Soil contamination and accumulation of heavy metals in soil and agricultural products is one of the most important environmental that threatens the life of plants, animals and humans. This research was conducted to investigate the geo-statistical analysis of Pb and Cd distributed in the southwest of Isfahan using environmental indexes in 2017. Methods: This study is a ...
The effect of topography on the radiance record in satellite image, probably reduce the accuracy of algorithem impliementation on the images . Therefore, to reduce the effect of topography, various correction models based on interaction between light and object needs to be defined. This research introduces lombertin correction model (Cosine model) and non_lombertin correction model (mineart and...
This study aims to recognize effect of Ordinary Kriging (OK) and Inverse Distance Weighted (IDW) estimation methods for separation of geochemical anomalies based on soil samples using Concentration-Area (C-A) fractal model in Irankuh area, central Iran. Variograms and anisotropic ellipsoid were generated for the Pb and Zn distribution. Thresholds values from the C-A log-log plots based on the e...
