"Conventional liquid/liquid extractions (500 ml samples) with gas chromatography/mass spectrometry detection was used to obtain a fingerprint of organic contaminants present in pulp-and- paper mill effluent from the Weldwood of Canada Ltd. bleached kraft mill. These fingerprints were compared with data obtained from small volume (2ul, < 5mg) samples of biofilm exposed to effluent from the same mill. For the biofilm material, advances in tandem mass spectrometry (MS/MS) were used to obtain fingerprints of organic contaminants. The MS/MS technique was amenable to rapid analysis (< 35 min for sample preparation and instrumental analysis), minimal sample extraction steps and provided sensitive detection of target analytes. Preliminary results indicated that the biofilm contained classes of contaminants matching those in the raw effluent. These results suggest that the MS/MS product-ion scans are selective and sensitive for identifying classes of contaminants from pulp mill effluents in small quantities of biofilm. Further refinement of the technique is required for routine quantification of specific contaminants using authentic standards"--Report summary. Issued also in print format.
