Snapshot air quality measures are often not representative of statutory compliance. International air quality management practice typically requires 8 to 24 hours average figures for assessment, so to avoid transitional or intermittent type of contaminants. Purpose of these snapshots serves only as random & quick check for any need of further investigation.
