The Government takes new steps in particulate monitoring aided by ET

Defra collects, monitors and reports on particulate counting and speciation via its Particulate Counting and Speciation Network, which researches the composition and nature of particulate matter in ambient air.

The network's main aim is to provide information on the chemical composition of particulate matter for source apportionment and modelling.

As part of Defra's strategy to update equipment and use the best available monitoring technology it has commissioned Enviro Technology to expand the scope and capability of its network by installing two URG 9000B Ambient Ion Monitors.

The monitors will be configured for automatic particulate phase ion sampling and analysis, and installed at two London sites- one kerbside and the other urban background.

These will provide automatic, accurate, reliable and time-resolved measurements of particulate phase ions in ambient air including those contained in, for example, sea salt. The instruments will generate data that will lead to a clearer understanding of particulate composition in near real-time.

The two automatic ion monitors will measure anion and cation compounds in PM2.5 particles focusing on SO4-2 (sulphate), Na+ (sodium), NH4+ (ammonium), Ca2+ (calcium), NO3- (nitrate), K+ (potassium), Cl- (chloride) and Mg2+ (magnesium).

The URG installation will enable Defra to: measure a far wider suite of anion and cation species, remove or reduce the need for laboratory analysis and be able to automatically measure and record ions in real-time.

Duncan Mounsor from Enviro Technology, said: "ET, Defra and URG have invested considerable time into sourcing, testing and evaluating the equipment and we are confident that it will meet and exceed Defra's requirements. Real-time, on-line monitoring will also make a huge difference to how the data is collected making the whole process overall more effective."
