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 ...

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 ...
