Abstract

The National Physical Laboratory (NPL) is contracted to manage the UK Heavy Metals (HM) Air Quality Network. The HM Network measures and reports concentrations of a selection of heavy metals in the PM10 (particulate matter with an aerodynamic diameter < 10 µm) fraction of ambient air and deposition (precipitation) across the UK.

This report was prepared by NPL as part of the HM Network contract with the Environment Agency, on behalf of the Department for Environment, Food and Rural Affairs (Defra) and the Devolved Administrations: the Welsh Government; the Northern Ireland Executive, Department of Agriculture, Environment and Rural Affairs in Northern Ireland; and the Scottish Government.

This 2024 annual report contains:
- A summary of the HM Network structure, operation, and quality procedures.
- Annual mass concentrations of metals measured at all HM Network sites.
- Performance against relevant data quality objectives (DQOs) and requirements of the UK Air Quality Standards Regulations (AQSR) 2010.
- Highlighting of AQSR 2010 exceedances (for lead, nickel, arsenic, and cadmium in PM10), interpretation of data, and discussion of trends across the HM Network.
