Abstract
Abstract The extremely toxic antifouling pesticide tributyltin (TBT) was regulated in many countries in the 1980s and 1990s. The regulations have been successful in reducing the toxic threat posed by TBT in many locations around the world. However, there are also many locations at which recovery has not been seen, even 10 years after regulation. Because of continuing concern about the environmental hazards of TBT, the International Maritime Organization proposes to prohibit all antifouling uses of TBT by 2003, and the presence of TBT on ship hulls by 2008. Canada has recently announced a prohibition on the use of organ-otin antifouling paints by January 1, 2003. This article reviews the persistence, bioaccumulation and toxicity of TBT in aquatic environments, and concludes that TBT meets all such criteria for designation as a Track 1 substance under Canada's Toxic Substances Management Policy, necessitating measures to virtually eliminate it from the Canadian environment. Because of the long persistence of TBT in sediment, there may be a "legacy problem" in sediments in some locations in Canada for perhaps 20 to 30 years after a total ban.

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
