Speciation of metal(loid)s in environmental samples by X-ray absorption spectroscopy: A critical review

[Display omitted] •Strengths and weaknesses of XAS as a speciation technique are reviewed.•We explain the novel XFM approach referred to as XANES image stacking.•The X-ray absorption process is explained tangibly.•Linear combination fitting and abstract factor analysis of mixtures is explained.•Exam...
