Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, where the limit values set in the Air Quality Standards Regulations 2016 to control concentrations of particulate matter (PM10) in ambient air apply.

The limit values set in the Air Quality Standards Regulations (2010) to control concentrations of particulate matter (PM10) in ambient air apply across the UK. Compliance with the limit values is assessed through a combination of monitored and modelled data, with non-compliance being determined if any one location breaches the limit value.
