Nitrogen dioxide (NO2) and Volatile Organic Compounds (VOC’s)
NO2 is measured in real time at Halkett Place and at 12 sites around the Island using passive diffusion tubes which are sent off monthly for analysis. Diffusion tubes are also used to measure four VOC’s at six other sites around the Island.
The results and analysis of this monitoring is published annually in a report by UK consultants Ricardo-AEA and is available to download below.

Halkett Place
Howard Davis Park
Environmental Health operates two Osiris units which measure Particulate Matter in real time.
One is based at Halkett Place in St. Helier and the other is at Howard Davis Park in St. Helier. The data from these is shown in the graphs above. The data shown covers the latest 24 hours of reporting.
View further real-time air quality data monitoring at our monitoring sites on the
AirQWeb website and on our air pollution monitoring website.
Apps
Download the AirQApp application that displays results from environment sensors that collect data on air quality information along with any external sensors such as pollutant gases and noice levels.
Air quality reports and documents
Environmental Health publishes analysis and discussion of the particulate monitoring program annually which can be found below along with our Air Quality Strategy, which sets out targets and objectives aimed at maintaining or improving the Air Quality on the Island and our Air Quality Project Plan which details more specifically what actions are planned over the coming year.
