Profiling Accumulated PAHs and Metabolomic Responses in Truncate Soft-Shell Clam (Mya truncata) in the Canadian Arctic
Bibliographic record
Abstract
This dataset included contaminant data of polycyclic aromatic hydrocarbons (PAHs) and a variety of metabolites measured in truncate softshell clams (Mya truncata) collected near Iqaluit, Canada. Clams were hand collected during extreme low tide from two locations (n = 10) in Koojesse Inlet in August 2022. Samples were collected to determine the extent of PAH contamination in the region and the possible impacts it would have on clam populations as well as local communities that rely upon this species as a locally harvested food source. In total, 52 alkylated and non-alkylated PAHs were assessed in clam whole bodies, including the US Environmental Protection Agency’s 16 priority PAHs. 51 metabolites were assessed in both the mantle and gills, and all clams were assessed for length, width, thickness, body mass and body condition. This study was performed as a follow-up to a previous study of clams from the same locations performed in 2019 that investigated growth, biomarker responses and accumulation of inorganic elements in response to municipal wastewater exposure. This project is part of the Coastal Environmental Baseline Program Initiative under the Oceans Protection Plan of Fisheries and Oceans Canada and is funded through the Ecosystems and Oceans Science Contribution Framework.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
