What AQ26 is ready for

AQ26 is ready for external methodology, provenance, data-gap and challenge interrogation. It is not yet a public claims engine for causation, breach, compliance or health effects.

External interrogation lenses

IAQM / AQEG / atmospheric-science review

  • Are target-matching and monitor-selection rules sufficiently conservative?
  • Are receptor, background and comparator monitors separated correctly?
  • Are meteorology and time-alignment gates explicit before interpretation?

UKHSA / WHO / public-health review

  • Does the public output avoid unsupported health-causation claims?
  • Are PM2.5, PM10, NO2, SO2, O3 and CO benchmarked separately from source attribution?
  • Are vulnerability/receptor flags presented as context, not diagnosis?

Clean Air Programme / Clean Air Fund / EEA

  • Is the data provenance clear enough for reuse and challenge?
  • Are data gaps visible and actionable?
  • Are official networks and open-data feeds preserved with source URLs and access dates?

UKWIN / ToxicoWatch / GAIA / Zero Waste reviewers

  • Are permitting, compliance, emissions and waste-policy questions kept traceable?
  • Are campaign-source materials separated from official records and peer-reviewed studies?
  • Are alternative explanations and contrary evidence recorded before public claims?

Named scientific reviewers and independent experts

  • Which source record supports each statement?
  • What uncertainty remains before a stronger claim could be made?
  • What additional monitoring, modelling or records would materially improve confidence?

Benchmark cards are public-health context only. They are not source-attribution findings.

Claim boundary

No causal, legal, medical, regulatory, laboratory or source-attribution determination is made by the automated public output.
