Analysis of fin and non‐fin fish products for azamethiphos and dichlorvos residues from the Canadian retail market
Bibliographic record
Abstract
Summary The organophosphate pesticides, azamethiphos and dichlorvos, have been used in the aquaculture industry for sea lice control around the globe. Only azamethiphos was registered for aquaculture purposes in the 1990s and early 2000s in Canada; however, dichlorvos is used for this activity in other countries. Canada imports fish and shellfish from around the world for human consumption. To complete human exposure assessments, the determination of these organophosphate pesticides in fin and non‐fin fish products from Canada and other countries was performed ( n = 140) using liquid chromatography‐tandem mass spectrometry. Neither of these compounds was found at levels above the method detection limit (0.01–2 and 0.1–14 ng g −1 of azamethiphos and dichlorvos, respectively) in any fish product analysed in the present study, suggesting that their use does not contribute to dietary intake via consumption of fish.

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.
