PFAS raise their ugly head in malaria control: Diverging views on risk substitution
Bibliographic record
Abstract
A controversy has arisen over whether or not the replacement of PFAS compounds as a binder between insecticides and nets by other compounds has affected the nets' efficacy in preventing malaria transmission. Robert Bos places this matter in a broader and historical context and concludes that now is the time to revisit earlier concepts and provide sustainable malaria prevention and control with a broader foundation aiming for truly resilient results. The need to promote institutional arrangements conducive to intersectoral action is as great in WHO Member States as it is within the structure of the World Health Organization itself. Robert Bos is former Executive Secretary, WHO/FAO/UNEP/UN-Habitat Panel of Experts on Environmental Management for Vector Control, WHO, Geneva (1983-1995) former Scientist, Division of Environmental Health, later Department of Sustainable Development and Healthy Environments, later Department of Public Health and Environment, WHO, Geneva (1995-2009) and former Coordinator, Water, Sanitation and Health, WHO, Geneva (2009-2013).

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.
