Local Air Quality Management (LAQM)
Local Authorities are required to carry out regular reviews and assessments of air quality in their areas. This involves measuring air pollution and trying to predict how it will change in the next few years. The aim of the review is to make sure that thenational air quality objectives. will be achieved throughout the UK by the relevant deadlines. These objectives have been put in place to protect people's health and the environment.
These are reported annually to DEFRA and placed on the Councilwebsite. If an exceedence of any objectives are likely the Local Authority is required to declare an Air Quality Management Area (AQMA) and then prepare an Action Plan which outlines what must be done to meet the objectives in future.This area could be just one or two streets, or it could be much bigger.
In Breckland, we have 2 continuous monitoring stations. The one at East Wretham is equipped to monitor fine particles (PM10) oxides of nitrogen (NOx) and the Swaffham one monitors oxides of nitrogen (NOx). The stations measure 15 minute averages so we can see the daily fluctuations in pollutant concentrations.
We currently have a district wide nitrogen dioxide (NO2 ) network of over 30 NO2 diffusion tubes. Diffusion tubes measure monthly average pollutant concentrations and allow the annual average to be measured.
The figures from the continuous monitors and the diffusion tubes are used in the reports made to DEFRA.
Breckland has declared an AQMA inSwaffham.
Information on our AQMA can be found on theDEFRA website.
