    High Spatial Resolution Chemical Imaging of Inorganic and Organometallic Pesticides
    Author(s): Richard Ortega and Asuncion CarmonaRichard Ortega and Asuncion Carmona

    The recent development of high spatial resolution analytical methods for inorganic element imaging enables the sensitive determination of inorganic and organometallic-based pesticides, at the cellular and subcellular levels. Some organic agrochemicals can also be investigated providing they contain one or more hetero-element, such as the halogens fluorine or bromine. Several micro-chemical imaging methods are currently available and will be reviewed in this article: Electron Microscopy combined to Energy Dispersive X-ray Spectrometry (EM-EDS), PIXE (Particle Induced X-ray Emission), SXRF (Synchrotron Radiation X-ray Fluorescence) combined to micro-XAS (X-ray Absorption Spectroscopy), and Secondary Ion Mass Spectrometry (SIMS). Although these methods offer a high potential in the understanding of the cellular mechanisms of pesticides toxicity, they have not been much used yet in this d.. Read More»
