The almost closed environment means that high levels of air pollution often occur inside the tunnels. The limit values for the pollutants are often higher in tunnels than in open ambient air because the exposure time is normally limited, but it may still be necessary to monitor that the limit values are not exceeded. Traffic tunnels often have to be provided with ventilation to keep the levels of air pollutants below the applicable limit values. To save energy, however, it is common not to operate the fans more ...

Monitoring the air quality at and around airports can be done for several reasons. It may be a question of monitoring the pollutants that employees and passengers are exposed to, but it may also be a matter of studying the contribution of aviation and ground traffic to pollution. Regardless of purpose, monitoring can be a challenge. The location of the measurement site must be representative. A large number of gaseous components need to be monitored with high accuracy and high ...

Port environments can be particularly exposed to air pollution, both in gaseous form and as particles. The ships are an obvious source, but both activities related to the unloading and loading of goods and land traffic to and from the ports can also contribute. Monitoring the concentration of air pollutants can be done both in order to monitor the environment in general and to map the sources. In the case of emissions from ships, it may be of particular interest to monitor sulfur dioxide (SO2) levels near the ...

How clean is the ambient air in our cities? A common strategy for monitoring the air quality in a city is to measure at ground level where people actually live and are at risk of exposure to air pollution. Often, there is also a requirement that the measurements are made in a place where you can expect the air pollution to be relatively high, which often means along one of the city's busier streets. Limit values for air quality often apply precisely to these locations. OPSIS offers several monitoring systems for ...

Air pollution at regional and national scales. It is important to monitor air pollution where many people stay, i.e. in cities and especially at street level. In order to better understand where the pollution comes from, a so-called background monitoring may also be needed. Then the monitoring station is placed in the countryside, at a great distance from obvious sources of the ...

There can be several purposes for monitoring the air quality in an urban area. If the aim is to assess what the residents are exposed to in the worst case, a so-called street-level monitoring is carried out. If the aim is to monitor the general levels of air pollution and follow up long-term trends, you should instead monitor further away from the busiest roads, for example at roof level. ...

Benzene monitoring around refineries: Measuring benzene emissions from a refinery plant can be challenging, but OPSIS makes it easy. Benzene is a liquid hydrocarbon that evaporates rapidly when exposed to ambient air. It is one of the more common substances used in the chemical industry and is particularly prevalent at refineries and similar operations. Benzene causes cancer and is therefore subject to ...
