All house prices in ChichesterIs the air quality good in Chichester?
Background NO₂ in Chichester is 7.3 µg/m³, below the WHO guideline of 10, and higher than the typical area (7.2). That puts it in the Typical band. Background PM2.5 in Chichester is 8.4 µg/m³, 1.7 times the WHO guideline of 5, and higher than the typical area (7.4). That puts it in the Very High band. Most of England and Wales is above the WHO guideline for PM2.5, so the bands compare places with each other rather than giving a pass or fail.
Nitrogen dioxide (NO₂): 7.3 µg/m³
NO₂ level is Typical, on a scale from Very Low to Very High.
Typical means the middle fifth of areas in England and Wales for NO₂.
| Very Low | up to 4.7 |
|---|---|
| Low | 4.7 to 6.5 |
| Typical | 6.5 to 7.7 |
| High | 7.7 to 9.2 |
| Very High | over 9.2 |
WHO guideline: 10 µg/m³ (in the Very High band). UK legal limit: 40 µg/m³.
Fine particles (PM2.5): 8.4 µg/m³
PM2.5 level is Very High, on a scale from Very Low to Very High.
Very High means the highest fifth of areas in England and Wales for PM2.5.
| Very Low | up to 6.0 |
|---|---|
| Low | 6.0 to 7.2 |
| Typical | 7.2 to 7.7 |
| High | 7.7 to 8.2 |
| Very High | over 8.2 |
WHO guideline: 5 µg/m³ (in the Very Low band). UK legal limit: 20 µg/m³, with a target of 10 µg/m³ in England by 2040.
The bands split every area we cover into fifths by its level, from Very Low to Very High. The map uses the same colours.
