Air des lieux de travail — Dosage de l'arsenic particulaire, des composés particulaires de l'arsenic et des vapeurs de trioxyde d'arsenic — Méthode par production d'hydrures et spectrométrie d'absorption atomique

Gives a method by hydrid generation for the atomic absorption spectrometric determination of the mass concentration of particulate arsenic, arsenic compounds and arsenic trioxide vapour in workplace air. Applicable to the determination of mass concentrations of approximately 100 ng to 125 g of arsenic per sample. Not suitable for the determination of arsenic in the form of metal arsenides.
