System and scale

Air quality depends on transport, heating, industry, weather and terrain. A daily average concentration and a short peak answer different exposure questions.

Observation and evidence

Water risk includes quantity, quality, infrastructure and transboundary governance. Network wear and source condition are distinct causes of water-supply problems.

Public significance

The Aral, Semipalatinsk and industrial zones have different harm mechanisms and evidence bases. Linking pollution to illness requires epidemiology and exposure data, not geographic coincidence.

Uncertainty and risk

A monitoring station describes its location and period, not automatically an entire city or region. A public statement should name pollutant, unit, interval, comparison standard and source.

Chronology

Chronology does not apply. The dossier describes a system; observations and assessments have their own dates and methods.

Environmental risks vary by basin, city and source; water, air, soil and health data cannot be collapsed into one indicator.
