Abstract
Abstract Mytilus edulis were collected intertidally from 16–18 sites located around the perimeter of Halifax Harbour, of an island located at the entrance to the harbour and from the Northwest Arm. The concentrations of 31 polycyclic aromatic hydrocarbons (PAHs), lipid and moisture content were determined in pools of this filter feeder sampled over three seasons spanning two years, along with calculating individual condition indices. Contaminants were nearly undetectable in many of the summer mussels and highest in some of the spring samples. At several sites, the sum of PAHs expressed on a dry or lipid weight basis, was either equal or higher in April compared to November. Fluoranthene was the most predominant PAH followed by pyrene and phenanthrene. At most sites, parental PAHs, associated with combustion sources of contamination, were more abundant than alkylated derivatives. A larger petroleum input was noticeable in mussel extracts from sites in close proximity to potential sources.

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 it
