Nanoparticles and interfaces with toxic elements in fluvial suspended sediment

Studies examining nanoparticles (NPs) and hazardous elements (HEs) contained in suspended sediments (SSs) are vital for watershed administration ecological impact evaluation. The biochemical consequence of titanium-nanoparticles (Ti-NPs) from SSs Colombia's Magdalena River was examined utilizing an innovative approach involving nanogeochemistry this study. In general, the toxicity human health risk assessment associated with presence some Ti-NPs + HEs riverine systems need to be determined a robust analytical procedure. mode occurrence Ti-NPs, total Ti other within were evaluated through advanced electron microscopy (field emission scanning microscope-FE-SEM high resolution transmission microscope-HR-TEM) coupled energy dispersive X-ray microanalysis system (EDS); X-Ray Diffractions (XRD); inductively plasma-mass spectrometry (ICP-MS). This work showed that enormous quantities present river studied they displayed diverse geochemical properties posed various possible dangers. Ti-NP contamination indices must established measuring environmental magnitudes NP determining rank among rivers. Finally, SS guidelines recommended on international level. study contributes scientific understanding relationship HE dynamics around world.
