Industrial companies regulated by us under the Environmental Permitting Regulations are required to measure emissions from their chimney-stacks.
-
Emissions monitoring from chimney-stacks should only be carried out by accredited test laboratories, using certified staff, or industrial companies with their own certified staff.
-
Continuous air quality monitoring ensures that the environment is being properly protected.
-
We require industrial companies to sample some pollutants in chimneys and flues using isokinetic samplers. Isokinetic means the velocity of gas entering the sampler is the same as in the chimney or flue.
-
Portable equipment is often used to monitor pollution from industrial chimney stacks, landfill sites and leaking pipes.
-
AQMAU is the Environment Agency's national focus of expertise on air quality modelling and assessment, providing both leadership and operational support.
