Dissolved and Particulate PBDE Concentrations in the Strait of Georgia, Juan de Fuca Strait, Burrard Inlet and the Fraser River (2013-2018)
Bibliographic record
Abstract
Fifty-five filtered seawater and twenty-one suspended particles samples were collected in the Strait of Georgia and surrounding areas on multiple research cruises between 2013 and 2018. The samples were processed within 48 hrs after collection and sent to SGS AXYS Analytical Services Ltd. (Sidney, B.C., Canada) to measure PBDEs. The dataset includes the dissolved and particulate concentration (pg/kg and pg/L, respectively) of 40 PBDE congeners in each sample, the weight of water (kg) from which dissolved PBDEs were extracted or the volume of water (L) filtered to collect the suspended particles, and mass of congeners in the analytical and procedural blanks. The limits of detection and quantification were determined from the standard deviations of the analytical blanks (3 and 10 standard deviations, respectively). The reported congener concentrations have been blank-corrected. The mass of congeners found to be below their limit of detection or quantification are reported as ranges (0 - LoD, or LoD - LoQ, respectively).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
