Air Monitoring 27


is calculated and what are realistic maximum values for them. European standardization organization CEN and its technical committee TC264 Air quality has an important role in this case since CEN/TC264 and its working groups write standards for emission measurements (among other topics). These EN- standards are used as “tools” in compliance assessment when plant owners show to local authorities that their emissions are below set emission limit values (ELVs).


Many TC 264 measurement standards have been written and validated at the time when emissions were on higher level and now, with lower ELVs, we must have new validation tests in order to fi nd out what are realistic MUs for these methods. Therefore, it is important that, both at national and at European level, enough support is given to standardisation work. The work of national experts giving their input to the standardization is typically funded by the Member States themselves. Now, funding for the validation of the standards at low concentration levels is an important, and critical, prerequisite so that standards and their performance characteristics can be revised


for low concentration levels. The overall aim is to ensure that even with low emission levels, the emission measurement results are transparent and robust throughout the EU.

Special off er for air sampling instrumentation


It is estimated that every 30 seconds, somewhere in the world, one worker dies as a result of exposure to hazardous substances.1 Air sampling pumps, once calibrated, can help protect the workforce by quantifying personal exposure and ensuring compliance with regulatory limits. Casella is offering a free Flow Detective™ Plus calibrator with the purchase of its VAPex Pro or Apex2 Plus/ Pro kits to improve air sampling accuracy and traceability and, ultimately, keep more workers safe.


The Flow Detective™ Plus is an electronic air fl ow metre calibrator, designed to measure the fl ow of air sampling pumps to within 2% accuracy. This robust solution can calibrate within airfl ows of 20mL/min to 5,000 mL/min to ensure correct fl ow. Compatible with Casella’s pioneering Airwave App and Bluetooth connectivity, calibration results can be sent via email, ensuring improved traceability and pump calibration procedures.


The Flow Detective™ Plus was the fi rst calibrator on the market capable of measuring pulsation, indicating if the airfl ow pulsation exceeds 10% for true confi dence in the integrity of samples. When used with the Casella Apex2 or VAPex air sampling pumps, the Flow Detective™ Plus can achieve closed-loop automatic calibration, eliminating manual input, and drastically saving time when calibrating pumps.


The VAPex Pro has been designed for the low fl ow sampling of vapours and gases in working environments, with a wide fl ow range of 20mL-500mL/min, this personal sampling pump has outstanding back pressure capability.


Apex2 Plus/Pro is for fl ows up to 5L/min; this medium fl ow air sampling pump is built to monitor workplace dust levels to help protect workers from long latency health problems resulting from occupational exposures.


Until December 16th 2022, any customer who purchases the VAPex Pro or Apex2 Plus/Pro air sampling pump kits, which include fi ve pumps, will receive the Flow Detective™ Plus air fl ow calibrator free of charge.


Tim Turney, Casella’s Global Marketing Manager comments, “Casella is proud to be offering access to the Flow Detective Plus through its quality range of air sampling products. With equipment that is easy to use, providing instant results, identifying any issues and changing processes instantaneously can help enhance the long-term health and quality of life for workers.”

EarthSense, has launched its Air Quality Reporting service, providing local authorities and commercial companies with a selection of reports on their measured air quality data.


The new Air Quality Reporting service provides EarthSense customers with standard, enhanced, and bespoke reports, giving them an option to receive reports that include appropriate levels of information, from a top-level analysis of air quality measurements to a comprehensive investigation into air quality, sources, exceedances, and more.


Tom Hall, Managing Director at EarthSense said: “Understanding air quality data may be a challenging and timely task for some, such as those waiting for reports from external companies, or people who are unfamiliar with analysing measurements. With our new Air Quality Reports, we can deliver usable insights and offer specialist translation of statistics for our clients and present it in a way that provides answers to air pollution challenges.”


The reports use data from EarthSense’s MyAir® web-based data application, such as the raw Zephyr® monitor


measurements, one hour, eight hour and 24 hour mean measurements and trends, as well as integrated meteorological data from the National Oceanic Atmospheric Administration (NOAA).


Hall continued: “Subject to the type of report chosen, the new service means that organisations such as local authorities, transport, and construction companies can make quick, strategic decisions based on empirical evidence to improve air quality. We can tailor reports to support local councils for their Annual Summary Reports, demonstrate a construction company’s compliance with regulatory limits in a specifi ed area, or research a wide range of fi elds such as demographics, urban planning, and explore its relationship with air quality for customers with various challenges.”


Available per calendar month, customers can select their Zephyr® monitors of interest and receive standard reports which


summarise the recorded air quality measurements and ambient climatic data for those locations. This data is presented in a set of graphical information and tabulated metrics following industry standard formats. Standard reports enable users to better understand the performance of their Zephyr®


trends, evidence compliance with regulatory limits, and view how well their intervention strategies are working.


EarthSense also offer enhanced reports which provide a more detailed analysis of air quality data extracted from the MyAir®


web app, with additional contextual insights from EarthSense experts. The reports translate pure statistical information into an easy-to-understand format, giving Zephyr® quality issues and potential improvements.


customers increased knowledge and understanding of air


Customers can select the time period over which they would like their enhanced reports to run, and EarthSense’s in-house experts will use data from deployed Zephyr®


monitors to deliver an analytical assessment of air pollution, exceedances,


and comparisons against UK, European or World Health Organisation (WHO) objectives. The reports will also provide customers with commentary, such as potential reasons why exceedances may have occurred, or guidance about types of mitigation strategies that may be effective for reducing the effects of measured air pollution.


Bespoke reports are also available, these are tailored for the customer to address a particular challenge or requirement. Customers are able to request a report based on a particular subject over a specifi ed time period, such as an exploration into the links between demographics, geographical areas, and air quality exposure; an investigation into how meteorological conditions impact air quality; or a study into the effect of a particular emission type (for example, woodburning stoves) on air pollution levels and community exposure.


Depending on the topic being investigated, the reports may integrate third party data either provided by the customer or obtained by EarthSense, analysed in conjunction with EarthSense’s Zephyr® deliver an in-depth examination of the required topics.
