The Environmental Health Section undertakes monitoring for Nitrogen Dioxide (NO2) at sites throughout the district.
Nitrogen dioxide is a colourless gas produced by combustion processes and is emitted from vehicle exhausts.
It can have an adverse health impact at high levels. To protect the public a level is set by legislation that is sufficiently low that the concentration of nitrogen dioxide normally found is unlikely to have any health effects.
We also submit an annual report on air quality in our area to the department of the environment, food and rural affairs (defra).
Mid Sussex District Council are members of the Sussex Air Quality Partnership (Sussex Air) which benefits from the co-ordinated monitoring of air pollutants across the region.
Recent air quality reports undertaken are:
- Air Quality Annual Status Report 2017
- Air Quality Annual Status Report 2016
- Air Quality Updating & Screening Assessment 2015
- Air Quality Progress Report 2014
- Air Quality Progress Report 2013
- Air Quality Updating & Screening Assessment 2012
- Detailed Assessment 2011
- Air Quality Progress Report 2011
- Air Quality Progress Report 2010
- Air Quality Updating & Screening Assessment 2009
The Updating & Screening Assessment 2009 identified that NO2 concentrations were likely to exceed the annual objective of 40 ug/m3 at dwellings at Stonepound Crossroads, Hassocks. Further monitoring was undertaken and a Detailed Assessment was completed in 2011. This confirmed that the objective would be exceeded in the area, which meant that it had to be designated an Air Quality Management Area with defra. The Council has since published an action plan, approved by defra,which can be viewed at Stonepound Crossroads AQMA Hassocks and sets out how air quality may be improved to meet the objective.
