Abstract Threshold limit values are set for molecules or chemical forms specified according to their toxicity. Pollutant quantification for inorganic substances is very often performed using elemental analytical techniques, but the need for speciation analysis of the different chemical forms is increasingly felt, despite the fact that the required methods are not always available. This article explains the meaning of speciation (determination of the chemical form in which an element is present in a given sample), provides examples of potential problems (e.g. in the areas of galvanization, and exposure to silver and chromium compounds) and proposes a prevention approach in cases for which there are no analytical methods.
