Analyser Air Quality Quarterly Data
Data provided by the environment team. A valueof 0 indicates the data has not yet been provided for that timeframe. All data is to be treated as provisional until the final ratified annual averages are determined. The annual average objective for PM10 and NO2 is 40µg/m3 and for PM2.5 20µg/m3 Results for ADA1 and ADA2 are indicative due to the monitoring technique being used.
