The air we breathe contains a mixture of gases and particles that can vary according to human activity, weather conditions and natural phenomena. Atmospheric pollution degrades air quality in the environment and inside buildings, exposing people to real health risks.
Unfortunately, human activities are the main source of air pollution in many parts of the world:
industrial activities: factories, thermal power plants, oil refineries...
- transport: cars, trucks, planes...
- domestic heating: wood, coal, fuel oil
- agricultural practices: intensive livestock farming, use of fertilizers, etc.
- daily activities in a context of increasing urbanization.
To combat this ambient air pollution effectively, it is essential to monitor air quality in real time by setting up measuring stations that continuously analyze the main pollutants, and enable air quality indices such as ATMO or CAS (Quebec) to be calculated.
The evolution of a certain number of atmospheric pollutants can thus be monitored on a daily basis, including nitrogen dioxide, sulfur dioxide, carbon monoxide, hydrogen sulfide, fine particles, volatile organic compounds...
For indoor air quality monitoring, which concerns all buildings (shopping centers, schools, hospitals, offices, parking lots, workshops...), instruments are also needed for effective monitoring and intelligent control of ventilation systems.
- OSTARA, ambient air quality measurement station, dedicated to outdoor environments, particularly harsh environments; the Ostara station can also be fitted with auxiliary sensors for :
— global air monitoring: ultrasonic anemometer for wind speed
— global water monitoring: WiMo probe for measuring physicochemical parameters such as temperature, pressure, conductivity, turbidity, pH, etc. - AIRTEST : coming soon
Air pollution measuring stations can be installed at all sites requiring air quality monitoring due to dust and gas emissions, including :
- mining and quarrying
- oil and natural gas refineries, plants
- aluminum smelters, steel mills, foundries
- boilers and industrial furnaces,
- pulp and paper mills,
- power plants,
- construction sites,
- ports and coastal areas,
- urban environments
