Air quality reports and monitoring information

The District Council have monitored air pollution at sites throughout Derbyshire Dales for a number of years. More recently the effects of air quality on human health have received greater public attention and this has been recognised by the Government leading to the introduction of the National Air Quality Strategy.

The National Air Quality Strategy provides a framework for air quality control through air quality management and air quality objectives that should be met at designated receptors.

All local authorities were required to undertake an initial air quality review in 2000 and to assess where the air quality objectives for seven designated pollutants would be unlikely to be met by the appropriate compliance date. We completed the review and assessment and found that all the air quality objectives should be met and this has been confirmed in subsequent years.

The most recent report (June 2016) and earlier reports are available to download below.

The Derbyshire Environmental Protection Group (DEPG), a consortium of all local authorities within Derbyshire, has produced a summary document [PDF 92kb] containing the results of the 2009 Updating and Screening Assessments for the whole of Derbyshire. The document is available to download in PDF below.

Air Quality Monitoring - nitrogen dioxide

A nitrogen dioxide diffusion tube

We currently operate a network of 13 nitrogen dioxide diffusion tubes, located throughout the district.

New locations for sampling were identified in Autumn 2007, focusing on the main towns and busiest roads, and the latest round of sampling commenced in December 2007 for an indefinite period. The location of previous sampling points are presented in the 2007 Progress Report. Annual reports continue to detail locations.

Nitrogen oxides are formed during high temperature combustion processes from the oxidation of nitrogen in the air or fuel. Nitric oxide (NO) and nitrogen dioxide (NO2) are collectively known as NOX. The principal source is road traffic, which is responsible for approximately half the emissions in the UK. The greatest NO and NO2 emissions occur in urban areas where traffic is heaviest. Power generation and heating are other important sources.

Nitrogen oxides are released into the atmosphere mainly in the form of nitric oxide that is then readily oxidised to nitrogen dioxide by reaction with ozone. Elevated levels of NOX occur in urban environments under stable meteorological conditions when the air mass is unable to disperse. Nitrogen dioxide has a variety of environmental and health impacts. It is a respiratory irritant, may exacerbate asthma and possibly increase susceptibility to infection. In the presence of sunlight it reacts with hydrocarbons to produce photochemical pollutants such as ozone. In addition nitrogen oxides have a lifetime of approximately one day with respect to conversion to nitric acid. This nitric acid is in turn removed from the atmosphere by direct deposition to the ground or transfer to cloud or rainwater thereby contributing to acid deposition.

There are no predicted exceedances of the air quality objective for nitrogen dioxide.

Air Quality Monitoring - dust

The District Council did, until February 2011, undertake dust monitoring using frisbee-style deposition gauges at a number of locations around the district.  The introduction of the Environmental Protection Act 1990 and the Pollution Prevention and Control Regulations 2000 saw a marked improvement in dust suppression at mineral workings within the district, and a corresponding improvement (reduction) in the amount of dust recorded by the deposited gauges. There are no statutory limits for deposited dust or deposited calcium (deposited calcium is used to indicate whether the main source of the dust is from limestone quarrying activity).

A number of mineral planning consents require that quarry operators undertake routine dust assessments within, or adjacent, to the boundary of the mineral planning consent. These are routinely submitted to Environmental Health for review.

Air Quality Monitoring - Lead (Pb)

Airborne concentrations of lead from H J Enthoven and Sons have been monitored on a weekly basis by Derbyshire Dales District Council at different sites in South Darley since 1986.

The current site at Warren Carr has been monitored since 1991 and allows trends to be plotted for residential property located close to the site. The monitoring results are contained in the air quality reports below.
