The Aireas metrology network in and around Eindhoven, the Netherlands has been operational since 2013. The network is consisting of 30 stations, 6 of which are equipped with the stationary NanoMonitor (successor device of the NanoTracer RM). The Network is used to drive public awareness of the impact of environmental parameters. Actual values are available via a life map open to the public, and awareness is further driven by social media activities (eg YouTube). See website (in Dutch): www. ...

Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error. Automating the ...

Monitoring real emissions from vehicles with combustion engines. Emissions from vehicles powered by fossil fuels have traditionally been tested in laboratories, but the results rarely reflect reality. Therefore, rules regarding "Real Driving Emissions" (RDE) have been added. The emissions are then measured correctly in a real environment and during real driving. OPSIS offers an RDE monitoring system based on the well-proven DOAS ...

The US EPA’s method 30B is designed as a reference method for determination of mercury emissions with stack gases. The method uses sorbent traps to capture total mercury from stack gas. Use of different sorbent traps also enables mercury speciation measurement. Method 30B is widely used for regulatory CEMM verification and for national and international research programs. This technology was also adopted for PRC (HJ 917-2017) and EC (TS ...

Stack emissions testing (stack sampling or stack monitoring) is the experimental process for evaluating the characteristics of waste gas stream emissions into the atmosphere from industrial facilities to meet environmental standards. Stack testing measures the amount of specific regulated pollutants or surrogates being emitted or determines the destruction or removal efficiency of a control device used to reduce emissions at facilities. Stack monitoring is an important tool used to determine a facility’s ...

Environics units are a powerful tool in the fields of hypoxia, hyperoxia and hypercapnia. Scientists have successfully used the standard ROBD2 and ROBD3 as well as more tailored S3000 Gas mixers (such as the ReDO2 shown below) for these highly varied projects. To see some recent research topics that have appeared in peer-reviewed publications, including a recent study entitled, "Uncovering Latent Deficits Due to Mild Traumatic Brain Injury by Using Normobaric Hypoxia Stress" and a review of the potential ...

UFP exposure in urban areas may be dependent on the selected mode of operation. In this study (carried out by Institute of Environmental Assessment and Water Research Barcelona Spain and DICeM�University of Cassino and Southern Lazio, Cassino Italy) 78 trips with walking, bus, tram and subway have been assessed. The particle concentration proved to be lowest in subway travel, and highest while travelling in diesel bus. City centre traffic crossings show particle transient peaks above ...

Refrigerants such as R134a, R125, R404a and many others used in refrig-erants are combustible and extremely harmful to the environment. In accordance with the EU F-Gas Directive, refrigerating systems must therefore not only fulfil stringent leakage control requirements, but must also be equipped with a leak detection system for HHC refrigerants. ...

OPO-based photoacoustic spectroscopy (PAS) provides ultimately fast and sensitive trace gas analysis The photoacoustic infrared spectroscopy (PAS) is a very promising technology for trace gas detection and analysis in environmental or atmospheric monitoring, industrial process control or medical diagnostics. PAS is based on exciting rotational and vibrational states of gas-molecules with infra-red light pulses. The absorbed energy translates into kinetic energy pulses, which form an acoustic wave that can ...
