Traffic, especially in urban locations, is one of the greatest contributors to local air pollution. Traffic produces a variety of different pollutants, notably particulates, but also including NO2, NO, CO, hydrocarbons and in some cases SO2.
Monitoring of roadside pollution can be challenging as often it is difficult to find suitable locations for large air quality monitoring systems, thus monitoring sites are too far away to be representative of roadside air pollution. Small, compact units which can stand the harsh elements are ideal for this type of monitoring.
Roadside pollution concentrations can change quickly as types and volume of traffic changes and so instrumentation used must be able to cope with these rapidly changing conditions. Real time particulate monitoring such as the Protinus 1000 allow monitoring of particulates in real time, providing data that can give a true and accurate indication of particualte levels and how they change throughout the day.
Compact monitoring shelter can also be used in tandem with real time particulate monitors. These shelters are fitted out with a variety of analyzers and particulate monitors offering fast response, minimal maintenance and are uesd widelyfor roadside monitoring.
Instruments may include:
Ecotech can also incorporate our Aurora 2000 Correlating Aurora Nephelometer into these stations for provide real time (1 minute) data on PM concentrations.
