The Supply & Installation of PM2.5/PM10 Dual Particulate Monitor

The Supply & Installation of Dual PM2.5/PM10 Particulate Monitor

Background

Local Authorities have a statutory duty under the Environment Act 1995 to review an assess levels of air pollution in its Borough under a regime known as Local Air Quality Management (LAQM) . Sefton has been undertaking this review and assessment for a number of years and currently monitors certain atmospheric pollutants using a combination of real time automatic monitoring stations and passive diffusion tubes.

The LAQM regime has recently been reviewed by Government and a number of changes were made to the requirements. Most of these were administrative however an additional new role has been included in relation to PM2.5 (particulate matter less than 2.5 microns in diameter) Sefton along with all Local Authorities now has a duty to assess and then work towards reducing emissions and concentrations of PM2.5 in their local area.

Levels of PM2.5 are not currently measured in Sefton as this has never been a legal duty before.

In view of the above Sefton is looking to purchase and install a PM2.5 monitor in an existing monitoring station within the Borough to allow levels of PM2.5 to be monitored and inform the review and assessment process
