  1. Determination of thiaarenes and polycyclic aromatic hydrocarbons in workplace air of an aluminum reduction plant.

    Article - En anglais

    Quantitation of a variety of tetra-penta-and hexacyclic aromatic sulfur heterocycles (thiaarenes) in workplace air of an an aluminum reduction plant has been made by help of gas chromatography with atomic emission detection (GC-AED).

    Personal exposure to those thiaarenes and to polycyclic aromatic hydrocarbons depending on work categories has been evaluated.

    Summarized concentrations of the thiaarenes investigated have been found to be 0.4-19.0 mug/m3.

    When using sulfur selective AED, samples could be analyzed without a prior separation of the thiaarenes from the PAH.

    The present data indicate a contribution of thiaarenes to the overall toxicity of coal tar pitch volatiles in this work environment.
