Caveats
- Modelled from monitoring plus maps, weighted by where people live — not one street's reading.
- There is no known safe threshold: lower is better all the way down.
- Lower means cleaner air on average.
Missing or suppressed values are never shown as zero — every card above passed validation with a real numeric value.
