“…Previous studies have revealed that different land use types affect heavy metal concentrations in surface soil [ 32 , 33 ]; however, they did not consider the geological background. Therefore, our study further compared the effects of different land use types on soil heavy metals against different geological backgrounds ( Fig.…”

“…The dam construction type is often associated with the reservoir size, the terrain, and other local conditions, which may explain the relationship between construction type and effect on metal concentration. Land Cover was the third most important F.G. Land cover is another well-documented factor of soil-and hydrochemistry [47][48][49]. Different land cover types are associated with different intensities of human impact and different hydrological processes.…”

River sediments often contain potentially harmful pollutants such as metals. Much research has been conducted to identify factors involved in sediment concentrations of metals. While most metal pollution studies focus on smaller scales, it has been shown that basin-scale parameters are powerful predictors of river water quality. The present study focused on basin-scale factors of metal concentrations in river sediments. The study was performed on the contiguous USA using Random Forest (R.F.) to analyze the importance of different factors of the metal pollution potential of river sediments and evaluate the possibility of assessing this potential from basin characteristics. Results indicated that the most important factors belonged to the groups Geology, Dams, and Land cover. Rock characteristics (contents of K2O, CaO, and SiO2) and reservoir drainage area were strong factors. Vegetation indices were more important than land cover types. The response of different metals to basin-scale factors varied greatly. The R.F. models performed well with prediction errors of 16.5% to 28.1%, showing that basin-scale parameters hold sufficient information for predicting potential metal concentrations. The results contribute to research and policymaking dependent on understanding large-scale factors of metal pollution.

Unleashing the Power of Graphene-Based Nanomaterials for Chromium(VI) Ion Elimination from Water

Graphene-oxide-based nanomaterials have gained attention in recent years in the field of heavy metal removal. In this work, graphene oxide (GO) and graphene-oxide-coated silica nanoparticles (GO/SiO2) were synthesized for the efficient removal of Cr(VI) ions from water. Synthesized nanosorbents were characterized by FTIR, Raman spectroscopy, and Transmission Electron Microscopy (TEM). The effects of the pH and the concentration of Cr(VI) ions in adsorption, using GO and GO/SiO2, was studied using the batch process. The results of the study indicated that the maximum removal percentage was shown at pH 3 for both adsorbents. Comparatively, GO/SiO2 showed a higher removal percentage (92.28%) than GO (86.15%) for Cr(VI) at a concentration of 50 ppm. The results validate that the removal of Cr(VI) ions is highly concentration-dependent and pH-dependent. This study shows that GO and GO/SiO2 are efficient adsorbents and that GO/SiO2 has great potential over GO for the removal of Cr(VI) ions from water.
