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, see the Air Quality Monitoring in Jersey 2019.

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 are shown in the graphs below. The data shown covers the latest 24 hours of reporting.
The Halkett Place Osiris 2131 particle analyser is currently in the UK for calibration.

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.

Jersey Air Quality Project Plan
Jersey’s air quality outside the home is generally very good. We’ve been assessing and reporting on the quality of Island air since 1997 and
annual reports are available here.
