Cleanup of sediment extracts prior to PCB analysis
- Army Engineer Waterways Experiment Station, Vicksburg, MS (USA)
Data for PCB in sediment are often difficult to evaluate because different laboratories use different sediment extraction, extract cleanup, and analytical techniques to obtain the information. The presence of interfering substances in sediment extracts is a major potential source of error in PCB analysis of sediment. Failure to adequately remove such interfering substances prior to analysis can result in erroneous values for sediment PCB concentration. The authors report here comparative effects of four commonly used sediment extract cleanup procedures on oil and grease and sulfur concentrations determined in Chicago River sediment extracts. concentrations of PCB were also determined in the extract to determine what effect if any, interfering substances remaining in extracts following cleanup would have on capillary column GC determinations.
