NIOSH 7048

CADMIUM and compounds, as Cd

This test method uses atomic absorption (flame) to monitor cadmium. This is an elemental analysis and it will not distinguish Cd fume from Cd dust. Aliquots of the ashed samples can be analyzed separately for many additional metals. Method 7300 (ICP-AES) is an alternate, multielement measurement method with approximately the same sensitivity. Perform all acid digestions in a fume hood. Cadmium is a byproduct of zinc production. It was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to colour glass, and to stabilize plastic.

Analysis Type (Application Method): Atomic absorption
