📊 5 Norwich-Specific Air Quality Topics
1. PM2.5 4 µg/m³ Excellence
Performance: Below WHO 5 µg/m³ guideline - among UK's cleanest cities
Norwich's PM2.5 level of 4 µg/m³ is exceptional and puts the city among the UK's cleanest for fine particulate pollution. This is 20% below the WHO's strict annual guideline of 5 µg/m³ and far below the UK legal limit. Residents can enjoy outdoor activities without air quality concerns.
2. Lakenfields DEFRA AURN Station
Monitoring: Automatic monitoring station providing continuous PM2.5, NO2, PM10 data
The Lakenfields AURN (Automatic Urban and Rural Network) station is Norwich's DEFRA-operated automatic monitoring station, part of the UK's national network of 164 stations. It provides continuous, hourly measurements of PM2.5, NO2, PM10, and other pollutants, contributing to national air quality assessments and informing local policy decisions.
3. AQI 22-37 (Good) Performance
Rating: Consistent Good air quality ratings reflecting low pollution levels
Norwich's Air Quality Index typically ranges from 22-37, classified as "Good" on the UK Daily Air Quality Index (DAQI) scale. This indicates low pollution levels and minimal health risks for the general population. "Good" air quality means outdoor activities can be enjoyed without concern - a stark contrast to larger urban areas with Moderate or Poor ratings.
4. No Air Quality Management Areas
Achievement: Norwich avoided AQMA designation through successful pollution prevention
Unlike many UK cities, Norwich has successfully avoided the need for Air Quality Management Areas (AQMAs). AQMAs are designated when pollution levels exceed legal limits, requiring councils to implement action plans. Norwich's achievement reflects proactive planning, lower traffic density, and geographic advantages that naturally disperse pollutants.
5. Indoor Air Quality Still Matters
Importance: Even with excellent outdoor air, indoor sources require filtration
Despite Norwich's excellent outdoor air quality (PM2.5 4 µg/m³, AQI 22-37 Good), indoor air quality still requires attention. Indoor sources like cooking (PM2.5 spikes from frying, grilling), cleaning products (VOCs), and poor ventilation can degrade indoor air regardless of outdoor conditions. MERV13/16 air purifiers remove 85-95% of indoor pollutants, ensuring healthy air year-round.
