IAEA-459

Marine Sediment    
Inorganic   Sediment

Origin and preparation of the material

A marine sediment sample was collected in Han River estuary, South Korea. This sediment was freeze-dried, ground and sieved at 125 µm.

The sieved sediment obtained, around 26 kg, with a particle size of less than 125 μm was homogenized by mixing it in a stainless steel rotating homogenizer for three weeks. Then, aliquots of about 50 g were packaged into cleaned amber glass bottles with aluminium screw caps, labelled IAEA-459 and sealed with Teflon tape.

This certified reference material is intended to be used as a quality control material for the assessment of a laboratory’s analytical work, for the development and validation of analytical procedures, and for quality assurance within a laboratory in the determination of chlorinated pesticides, PCBs, polybrominated diphenyl ethers and polycyclic aromatic hydrocarbons in sediment samples with very low concentration levels.
