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. aireas.com).
To measure the air quality in a city is a challenge. A large number of gaseous components need to be measured with high accuracy. The monitoring site needs to be representative for the city and the system has to be easy to maintain and calibrate. The OPSIS open-path monitoring systems provide a flexible solution, giving the average concentration for an area. A single OPSIS system can measure all relevant gaseous components set by the authorities, such as NO, NO2, SO2, O3, BTX, NH3.
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 DICeMï¿½University 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 1ï&iq...
With the application of air quality PM2.5 standards, people have a clear understanding and attention on ambient air quality, countries also present clear requirements and control objectives. Due to the speeding up of development process of cities construction in recent years, unceasing expands of the urban area and population scale, sustained growth of energy demand, motor vehicle ownership, various construction projects, the situation of urban air quality improvement work is more severe.
According to US EPA IO - 3.3 standard method of heavy metals, PMMS – 5000 uses XRF nondestructive testing technology and atmospheric automatic enrichment technology to realize the accurate measurement of atmosphere heavy metals such as lead, mercury, cadmium, chromium, arsenic, etc. It is widely used in environmental air quality monitoring places such as industrial pollution area, residential area, city, etc.
