Air Monitoring
professional engineers who are able to reach your facility within a certain timeframe. Monitoring equipment is highly specialist, often incorporating complex components such as spectrometers. Engineers need expert knowledge and training in order to service it adequately.
Modern technology means that many common glitches – such as the need for recalibration after a filter change - can be dealt with remotely. A good service provider will offer dedicated technical support with the capability to diagnose problems in quick time. In some cases, this will enable issues to be resolved remotely, or if an engineer does need to be deployed, they will have an understanding of the problem before they arrive and come equipped to deal with it.
You need to have confidence in the ongoing performance of equipment and be certain that any emergent problems will be dealt with quickly and efficiently. Cheaper service doesn’t necessarily equate to better value, and it could put a fracture in the foundations of your air quality or emissions monitoring.
Ultimately, good monitoring is the cornerstone of good management - and this is particularly true of air quality and emissions monitoring. As legislative requirements surrounding air quality and pollution increasingly go hand-in-hand with public demand for accessible air quality information, a robust strategy is essential. The best equipment and service providers understand this. As well as ensuring that your monitoring makes the grade, they will go the extra mile to provide intuitive graphs and tables making the data accessible to anyone who’s interested.
Case Study ET devises mobile monitoring units for Air Quality Cell
The Environment Agency-chaired Air Quality Cell, set up to provide a multi-agency response to major air quality incidents, is using sophisticated mobile units from Enviro Technology as a core strategy component.
Enviro Technology was selected for the multi-million pound project after a competitive pitch involving a complex brief. The air quality monitoring specialist is providing two bespoke, well-equipped vehicles that use groundbreaking technologies and meet stringent requirements, such as weight and power restrictions.
“In the event of a major incident the Air Quality Cell will be convened, and rapid response measures including vehicle deployment, are implemented,” explains Gillian Hickey from the Environment Agency. “The mobile stations need to be in situ, gathering data and samples for analysis, within hours of the initial alert. We chose to work with Enviro Technology as the team’s response to our challenging brief demonstrated intelligence and innovation.”
Enviro Technology has also secured a three year service and maintenance contract for the mobile monitoring stations. A dedicated engineer has been recruited to accompany the vehicles, provide onsite technical support and ensure all equipment is functioning at its optimum level for the duration of an incident.
Pollutants that can be detected and measured by equipment on
the mobile stations include SO2, Nox, NH3, CO, PM10 and PM2.5. The vehicles also carry their own generators and are fitted with pneumatic stabilisers. In addition, a 360° weather-proof webcam and net mast enable Agency staff to keep in touch with remote colleagues and share real-time incident information.
“This is probably the most exacting brief we have ever had to work with,” says Duncan Mounsor, Sales & Marketing Director at Enviro Technology. “But the result is a pair of truly state-of-the-art mobile air quality monitoring stations.”

3D Aerial Maps Help Model River Pollution
Computer generated 3D visualisations are being used to help study river pollution in the UK of the River Doe Lea. The research project, carried out by the National Trust with partner institutions the University of Sheffield, Environment Agency, Natural England and other consultancies aims to develop a multi-targeted catchment management strategy. Airborne remote sensing data, supplied by Bluesky (UK), was used as part of a PhD study carried out within the project. The digital aerial photography, Colour Infrared Imagery (CIR) and photogrammetrically derived digital height models were used to model the flow of agricultural pollutants and assess the diffusive effect on the landscape.
Results from the project ‘Modelling Catchment Landscapes Potential to Mitigate Diffuse Pollution from Agriculture’ were recently presented at an international conference on Catchment Science organised and attended by members of CatSci a multidisciplinary research programme in catchment science funded by the European Commission under the Marie Curie Early Stage Training Fellowship scheme.
Nataliya Tkachenko, author of the research project commented, “The primary aim of the study was to develop an interactive landscape model, which would give the possibility to evaluate mitigation options in scenario context and open opportunities for
participatory GIS applied to agriculture. This model is novel in the aspect of geotargeting of mitigation options within the real landscape, where solutions can be downscaled to the finer elements.
Evaluation of landscape processes in the context environment is highly complicated process, which requires substantial amount of data input on various temporal and spatial scales. Both 3D visualisation, CIR derived indicators and temporal data are powerful source of input information.”
She continued, “Being able to represent and visualise the countryside in all aspects was essential for the accurate modelling of the mitigating effects of the landscape on the agricultural pollutants studied. The Bluesky data was available off the shelf and in a format and specification suitable for use in our geographical information system (GIS) and image analysis software.”
The Bluesky data supplied to the University of Sheffield for this study is part of the GeoPerspectives product range. GeoPerspectives offers nationwide coverage of high resolution aerial photography and Colour Infrared imagery as well as highly accurate, photogrammetrically derived Digital Terrain Models (the earth’s surface excluding buildings and vegetation) and Digital Surface Models (the earth’s surface including buildings and vegetation).
Bluesky is also able to provide ultra detailed LiDAR (Light Detection and Ranging) data and services covering the majority of England and Wales including all major urban centres, coastal areas and flood plains.

Enviro Technology Appointed to Service Kent AQN
Enviro Technology (UK) has been selected by energy and climate change consultancy AEA Technology to manage the service and maintenance contract for the following Kent and Medway Air Quality Network sites: a background site just outside Ashford, a site on the cliffs above Dover Port, a suburban station in Folkestone and a town centre location in Tunbridge Wells.
The all-inclusive service contract incorporates a 48-hour response to breakdown, six-monthly services for each site, replacement of expendable and consumable parts as well as all spare parts. Air conditioning equipment within monitor housing is covered in addition to the main active components.
Equipment in operation across the network includes
NOx, PM10, O3 and SO2 analysers. The suburban station in Folkestone incorporates a full suite of Teledyne API
analysers. All of the analysers support remote interrogation, enabling Enviro Technology to diagnose and rectify any emerging problems quickly and efficiently.
“When we subcontract to third parties, it is vital that we have absolute confidence in their core capabilities and service levels – our reputation depends on their performance,” says Jo Green, Senior Air Consultant at AEA Technology. “Enviro Technology shares our commitment to customer service, and understands the importance of good, consistent air quality data.”
“Our offering is founded on the principle of excellence
– in terms of the service levels we meet, the technical skill of our engineers and the depth and breadth of our support,” says Nigel Macefield, Technical Services Manager at Enviro Technology. “We refuse to compromise on quality, and that’s why we insist on measures such as providing genuine manufacture replacement parts and spares within the contract fee.”
