All house prices in South GloucestershireIs the air quality good in South Gloucestershire?
Background NO₂ in South Gloucestershire is 9.6 µg/m³, about the WHO guideline of 10, and higher than the typical area (7.2). That puts it in the Very High band. Background PM2.5 in South Gloucestershire is 8.1 µg/m³, 1.6 times the WHO guideline of 5, and higher than the typical area (7.4). That puts it in the 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): 9.6 µg/m³
NO₂ 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 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): 8.1 µg/m³
PM2.5 level is High, on a scale from Very Low to Very High.
High means the second-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.
