오염물질 분석의 QC-한국의 예

Abstract

Standard reference materials (SRM) for contaminants analysis in sediment and biota were provided by NMEMC, China for intercalibration exercise. These SRM consist of freeze-dried mussel tissue, oyster tissue and sediment. Analyses of heavy metals, PAHs, PCBs and OCPs in SRM were conducted in the laboratory of KORDI. Hg was analyzed using CVAAS with gold-amalgamation. Cu, Pb, Cd, As, Cr, Mn, Co, Ni, Sn and Sb were analyzed using ICP-MS. Zn and Fe were measured by flame AAS method. 16 priority PAHs were analyzed on soxhlet extracts using pyrene d10 as a surrogate standard. Biological samples for PAHs analysis were subjected to Sephadex cleanup. GC-ECD were used for the qualification of PCB and OCPs after FLorisil cleanup of extracts. Compatible analytical technique will be set up through exchange of experts following the results of intercalibration exercise
