Method for the Determination of Three Toxic Non-Ortho chlorine Substituted Coplanar PCBs in Environmental Samples at Part-per-Trillion Levels
Abstract
A method has been devised combining alkali digestion, carbon chromatography and high-resolution gas chromatography for the determination of 3,3',4,4'-tetra, 3,3',4,4',5-penta, and 3,3',4,4',5,5'-hexachlorobiphenyl, the biologically active congeners of PCBs and approximate isostereomers of 2,3,7,8-TCDD. This method permits determinations of parts-per-trillion levels of these toxic residues in biological samples. Interference both from biogenic and from xenobiotic substances was reduced to extremely low levels. Using this method, 13.5 ng of 3,3'4,4'-tetrachlorobiphenyl/g, 0.89 ng of 3,3'4,4',5-pentachlorobiphenyl/g and 0.64 ng of 3,3',4,4'5,5'-hexachlorobiphenyl/g were detected on wet weight basis in the blubber of a finless porpoise. To our knowledge this is the first report on the three toxic non-ortho chlorine substituted PCB residues detected in a higher mammal in the wilderness.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
